Insurance

In law and economics, insurance is a form of risk management primarily used to hedge against the risk of a contingent, uncertain loss. Insurance is defined as the equitable transfer of the risk of a loss, from one entity to another, in exchange for payment. An insurer is a company selling the insurance; an insured, or policyholder, is the person or entity buying the insurance policy. The insurance rate is a factor used to determine the amount to be charged for a certain amount of insurance coverage, called the premium. Risk management, the practice of appraising and controlling risk, has evolved as a discrete field of study and practice.

The transaction involves the insured assuming a guaranteed and known relatively small loss in the form of payment to the insurer in exchange for the insurer's promise to compensate (indemnify) the insured in the case of a financial (personal) loss. The insured receives a contract, called the insurance policy, which details the conditions and circumstances under which the insured will be financially compensated

Principles

Insurance involves pooling funds from many insured entities (known as exposures) to pay for the losses that some may incur. The insured entities are therefore protected from risk for a fee, with the fee being dependent upon the frequency and severity of the event occurring. In order to be insurable, the risk insured against must meet certain characteristics in order to be an insurable risk. Insurance is a commercial enterprise and a major part of the financial services industry, but individual entities can also self-insure through saving money for possible future losses.^[1]

The Hardware Information Navigational Tool

The Hardware Information Navigational Tool, or HINT, is an information web service developed by the former AG Communications Systems (now Alcatel-Lucent) which displays hardware and software characteristics of a central office switching system. It displays the hardware equipment as it is positioned in the central office and shows how this equipment is being used. The program displays an interactive map, allowing the user to select the applicable states/provinces or country, then select the switching system, and then finally the module, circuit pack, and circuit. The statistical reports allow customers to maintain a watch on their resources. It is also useful for engineering and the daunting task of assigning all of the various telephony services.

All telephone exchanges are customized to local conditions. Because of this, there exists a dynamic difference between one central office to another due to capacity, provided features, and hardware vintages. HINT started out as an internal resource used by GTD-5 EAX Engineering Services, Remote Technical Assistance, and Sales Support. It was created with the intent to accurately view a customer’s unique hardware configuration without physically being present at the site. Deciphering the switch’s own Office Dependent Data (ODD), it provided switching system hardware images that were accurate and up-to-date. Through internal feedback and subsequent modifications, it evolved into a tool that was viable enough to be offered as a product and sought after by customers.

Due to the similarities between the GTD-5 EAX and the 5ESS product lines, numerous requests were made by HINT users to develop and expand the scope of HINT so that it includes the 5ESS switching system. After hearing the same request for several years and realizing the revenue potential of adding the 5ESS, AG expanded HINT to include the 5ESS switch type, providing the same features, look, and feel that has made the GTD-5 EAX version so popular.

Presently^[when?], over 90% of GTD-5 EAX switching systems are supported and maintained by the customer using HINT. These users have been using the tool for several years and purchase the service as a yearly subscription subject to annual scrutiny and review. Because of this, the vendor is continuously upgrading and adding new features to excite interest and retain its customer base.

Area 51

Area 51 is a nickname for a military base located in the southern portion of Nevada in the western United States (north-northwest of Las Vegas). Situated at its center, on the southern shore of Groom Lake, is a large military airfield and one of the most secretive places in the world. The base's primary purpose is to support development and testing of experimental aircraft and weapons systems.

The base lies within the United States Air Force's vast Nevada Test and Training Range. Although the facilities at the range are managed by the 99th Air Base Wing at Nellis Air Force Base, the Groom facility appears to be run as an adjunct of the Air Force Flight Test Center (AFFTC) at Edwards Air Force Base in the Mojave Desert, around 160 miles (260 km) from Groom, and as such the base is known as Air Force Flight Test Center (Detachment 3). Area 51 researcher Glenn Campbell claims that AFFTC Detachment 3 is located at Groom, citing the title of a leaked security manual, the mailbox in Henderson, Nevada he believes formerly served Groom, and the NASA biography of astronaut Carl E. Walz who was formerly a manager at AFFTC detachment 3 (AFFTC-DET3.)

How to Fix a Slow Running Computer

Finding your computer isn't running as though it is shiny and new? If so, then you definitely are in the right place. There are many reasons for a slow running computer, and having the proper knowledge, will definitely help you to remedy the problem.
Main Causes of a Slow Running Computer
Virus, Spyware or Malware infection
Windows Registry Problems
Severely fragments hard disk
Not enough hard drive space
The first four reasons are fairly easy to solve. To determine if you have spyware, malware or virus infection, simply scan for malware. To determine if you have a windows registry problem, then use a registry cleaner that will safely scan your computer's registry for errors, and automatically repairs them for you. If the problem is that you need more hard disk, then you can remove temporary files and unwanted programs or flies and run a disk cleanup utility. If your problem is that your hard disk is fragmented, then you will need to defragment your computer.
Other Reasons Your Computer May Be Running Slow
When you are running too many programs at once, your computer will slow down. Close some of them to determine if that is what you are experiencing.
If you are doing tasks such as watching movies, DVD burning, editing graphics, etc. these tasks may result in a slower running computer, as the demands on the computer's system is greater.
Corrupt or misbehaving programs. Files can become corrupt, and when they do, they will cause havoc on your computer.
Another cause may be that your computer does not have enough RAM. RAM stand for Random Access Memory and is your computer's memory. When you are short on RAM upgrading your PCs RAM will enhance its performance.
One major cause of a slow running computer is too many unnecessary programs which automatically load when the computer starts. By disabling these computer programs, you will improve the speed of your computer.
Also, your computer may be overheating. Check the fans to see if they are functioning properly. If for some reason, they are not, it will be necessary to replace or repair the fan unit.
The technology of a computer is a science, and it is proper to have the proper information. Learning how to prevent, and diagnose a slow computer is not something that takes a rocket scientist. There are easy to learn computer fixes that will help you to get your computer in prime running condition, once again, and save you the expense of a computer technician to troubleshoot and repair the problem.
Also, you should always practice maintenance with your computer. This means giving your computer regular tune ups. PC Tune up software is one of the easiest ways to fix endless computer problems and keep your PC in top running shape. By taking the necessary preventative measures, you will keep your computer in top running speed and have fewer problems as the software will help to eliminate the many problems associated with the operation of a computer.

A Face-Saver For The iPhone Police

Apple's newest iPhone, the 4S, has been on the market for a few weeks, but the saga surrounding the leak of a prototype of the previous-generation iPhone 4 is only now coming to a close.
Brian Hogan and Sage Wallower pleaded no contest to a misdemeanor charge of theft of lost property for selling a phone that an Apple tester accidentally left in a bar. The two men, both in their 20s and with no previous criminal records, each received a year of probation and 40 hours of community service. They were also ordered to pay Apple restitution of $250.
According to technology blog Gizmodo.com, it all started when Apple engineer Gray Powell headed out to celebrate his 27th birthday at a German beer garden. Powell accidentally left his phone at the bar. A forgotten phone isn't usually a newsworthy event - unless, of course, the phone involved is a top-secret design produced by one of the world's most notoriously close-mouthed technology companies, cleverly disguised as a run-of-the-mill older model. Which is exactly what Powell's phone was. (1)
Hogan, who was also at the beer garden that night, took the phone home, not realizing its true importance. He intended to return it the next day. Once he discovered what he had, he tried to contact Apple. His calls were ignored. Next, he and Wallower checked to see if perhaps a technology media outlet might take their story more seriously. Gizmodo, which is owned by Gawker Media LLC, listened. It offered $5,000 for the device. The site proceeded to post photos and conjectures about the new phone. Its software had been remotely disabled, but that didn't stop the enterprising editors from examining the hardware. Gizmodo says that when it was asked to return the phone, it immediately arranged to do so.
Apple, however, may not have been satisfied with just getting its phone back. The company, which keeps most of its prototypes bolted to desks in its super-secured campus, was not happy about photos of its upcoming product being splayed all over the Internet. Much of that displeasure was likely directed at Jason Chen, a Gizmodo editor who reported on the dissected phone's innards.
California's Rapid Enforcement Allied Computer Team (REACT) - Silicon Valley's high-tech police - raided Chen's home on the authority of a search warrant issued by San Mateo County Superior Court Judge Clifford V. Cretan. Officers left with a pile of computers and hard drives; Chen was left with a broken door.
Like others at the time, I believed the search to be illegal. While others invoked California's shield laws, which offer special protections for journalists, I saw no reason why anyone, journalist or not, should have been subject to a search when the evidence that any crime had actually been committed was minimal at best.
Eventually, the search warrant was withdrawn, which is a pretty good indication that it should not have been issued in the first place, and Chen's property was returned. Conveniently for Apple, however, Chen didn't get his computers and other research materials back until after the iPhone 4 was safely on the market.
Neither the men who sold the phone nor the journalist did anything obviously wrong in this case. Apple apologists (and government lawyers defending any lawsuits by Chen and Gizmodo, who were never charged) will claim the misdemeanor guilty pleas as evidence that justice, as well as beer, is served in Silicon Valley. If you believe this, I have an old IBM PCjr to sell you that will work just great as a server for your website.
Hogan and Wallower faced a pretty easy choice: They could take a slap on the wrist and get on with their lives, or they could run up a fortune in legal fees (which not every 20-something in Silicon Valley can afford) and risk felony convictions that would ruin their prospects for security clearances and job opportunities. Don't confuse justice with expediency.
REACT needs reform, and the San Mateo County bench could do with a little review on the legal and ethical hazards of being a hometown judge.
There were concerns about REACT long before the iPhone incident. The task force's website states that the organization "depends on our industry partners," who provide know-how and other support. After the iPhone raid, Nick Muyo, the public information officer of the Santa Clara County district attorney's office, told the Los Angeles Times that technology companies, including Apple, "have open invitations" to attend meetings of REACT's steering committee, and that many companies send representatives. (2)
Letting law enforcement get too cozy with private industry can lead to an erosion of professional judgment. Someone needed to tell Apple that interference with the choreography of its product rollouts is not a crime, and that journalists' homes and hard drives are not reference libraries.
Of course, there is another important lesson in this story: Don't take corporate secrets into a bar. According to some reports about a missing iPhone 4S in August, Apple may not have learned that one.
This time, however, no search warrants were issued. Apple's latest gizmo is nevertheless selling quite well.

Can Androids and Human Be Friends?

Is there any other choice?

Today's androids are showing up more human-appearing. They're constructed with new age materials, with artificial intelligence, using faster and more powerful computers. They're, all around, more talented and capable robots, embedded with new technologies. But where do you draw the line dividing the use of 'droids in life and in the workplace, from skilled human workers? So called unskilled workers for that matter. Already we're hearing warnings like: "Don't eat food prepared by a 'droid who can't taste it."

Could we reach a computer runaway, where androids take over, driving humans from all levels of society, including the rich and powerful, to the homeless, and everyone in the middle? Would this be good for humankind? Obviously not.

What if the androids did all the work, and the people all lived like kings from their labors? Would this be better? Initially maybe. But what if the 'droids took an unusual turn, due to the law of unexpected consequences? Maybe because of a mistake in their programming or contradiction in their perceived mandate. Maybe because over-population isn't good for us. How would this all turn out? Uncertain and real scary. Maybe it would end up in the first case anyway: an android takeover. Say you could live like a king if you spent all your waking moments trying to jump through impossible hoops; no joy there. Or maybe your 'droid servants would come to the conclusion ecotopia was best for you, and we'd all be living in the woods and as hunter-gatherers. Still having the title of king, of course. Not so good for the majority-a few would probably think it was great. They could live an idyllic life, unencumbered by technology intrusions: no phone calls, no utility bills, no computer problems, and no television - gulp.

In either case 'droids would be ascendant and humans would be in a bad way, even a threatened species. All 7 billion of us. The point is: Would the downfall of humanity be good for the androids? Not really. Why? Because it's unlikely that 'droids could make significant progress without that spark of human intelligence making it happen. Hopefully the androids would know this before things got too bad for humans. Or better, far-sighted human developers and programmers would instill this into androids in the first place. A lot of thought and adjustments would have to be made along the way. Obviously androids would have to live like humans: working jobs (or jobless) saving money, buying homes (or living with the homeless), paying utility bills, seeing professionals, and even doing travel and taking vacations.

The Basics of CISCO Password Management

Cisco is a system that many people take months or even years to fully learn. Thus, many people that are using this often feel as though they have to call in a professional for everything that they may need. However, when it comes to Cisco password the person is going to find that they can change this and make it better for their security, even if they are not the most computer savvy person that is out there.
First things first, the Cisco password is by default one that is going to use an Enable password, which is not helping to protect your router at all and is something that anyone with a little bit of knowledge can break into. Which is why, for security purposes, the person should be sure that they are changing this to an Enable Secret password.
To do this, the person must go into the Privileged Exec mode, which is going to allow them to have access to change the password. They are going to need a series of commands in order to do this, and this is something that they can find through various sources, such as forums and books. Once you think that you have this complete, try it out to make sure that it has taken.
The main question that most people have is how they would go about getting the password to work should they forget it or they were not the ones to program this in the first place. When this happens, first off, the person should not panic. The Cisco system was designed for a way to get around this, so it is possible to do this.
The person will want to get into ROM monitor mode which means that they will have to connect to the router through the actual port instead of wireless. Once they have done this the mode that they enter is basically the go to mode for when passwords are lost or are forgotten.
The rest of the procedure is completed according to what type of route that you have working for you. Thus, the person must consult the Cisco website to find distinct and clear instructions for their particular router. Using the wrong instructions will only lengthen the time it takes to get the router up and running again.
In most cases, once the person changes anything that is security like, including the passwords, they are going to find it best to restart the router in order to ensure that everything takes and the new security field is up and running. If they do not do this, they may find that they are putting their network at risk without taking these precautions.

Overall, changing the password to ensure the most security for your router is something that all Cisco users should do. They are going to find that this is rather simple and if they are ever in need of help there are many sources at their disposal such as http://www.firewall.cx which can be a huge source of information pertaining to Cisco.

Discrete mathematics

Discrete mathematics is the study of mathematical structures that are fundamentally discrete rather than continuous. In contrast to real numbers that have the property of varying "smoothly", the objects studied in discrete mathematics – such as integers, graphs, and statements in logic^[1] – do not vary smoothly in this way, but have distinct, separated values.^[2] Discrete mathematics therefore excludes topics in "continuous mathematics" such as calculus and analysis. Discrete objects can often be enumerated by integers. More formally, discrete mathematics has been characterized as the branch of mathematics dealing with countable sets^[3] (sets that have the same cardinality as subsets of the natural numbers, including rational numbers but not real numbers). However, there is no exact, universally agreed, definition of the term "discrete mathematics."^[4] Indeed, discrete mathematics is described less by what is included than by what is excluded: continuously varying quantities and related notions.

The set of objects studied in discrete mathematics can be finite or infinite. The term finite mathematics is sometimes applied to parts of the field of discrete mathematics that deals with finite sets, particularly those areas relevant to business.

Research in discrete mathematics increased in the latter half of the twentieth century partly due to the development of digital computers which operate in discrete steps and store data in discrete bits. Concepts and notations from discrete mathematics are useful in studying and describing objects and problems in branches of computer science, such as computer algorithms, programming languages, cryptography, automated theorem proving, and software development. Conversely, computer implementations are significant in applying ideas from discrete mathematics to real-world problems, such as in operations research.

Number theory

 

Number theory

 

Number theory is a branch of pure mathematics devoted primarily to the study of the integers. Number theorists study prime numbers (the building blocks of integers) as well as the properties of objects made out of integers (such as rational numbers) or defined as generalizations of the integers (such as, for example, algebraic integers).

Integers can be considered either in themselves or as solutions to equations (diophantine geometry). Questions in number theory are often best understood through the study of analytical objects (e.g., the Riemann zeta function) that encode properties of the integers, primes or other number-theoretic objects in some fashion (analytic number theory). One may also study real numbers in relation to rational numbers, e.g., as approximated by the latter (diophantine approximation).

The older term for number theory is arithmetic; by the early twentieth century,^[1] it had been superseded by "number theory". (The word "arithmetic" is used by the general public to mean "elementary calculations"; it has also acquired other meanings in mathematical logic, as in Peano arithmetic, and computer science, as in floating point arithmetic.) The use of the term arithmetic for number theory regained some ground in the second half of the 20th century, arguably in part due to French influence.^[2] In particular, arithmetical is preferred as an adjective to number-theoretic

Algebraic number theory

 

 

Algebraic number theory studies algebraic properties and algebraic objects of interest in number theory. (Thus, analytic and algebraic number theory can and do overlap: the former is defined by its methods, the latter by its objects of study.) A key topic is that of the algebraic numbers, which are generalizations of the rational numbers. Briefly, an algebraic number is any complex number that is a solution to some polynomial equation with rational coefficients; for example, every solution x of (say) is an algebraic number. Fields of algebraic numbers are also called algebraic number fields.

It could be argued that the simplest kind of number fields (viz., quadratic fields) were already studied by Gauss, as the discussion of quadratic forms in Disquisitiones arithmeticae can be restated in terms of ideals and norms in quadratic fields. (A quadratic field consists of all numbers of the form , where a and b are rational numbers and d is a fixed rational number whose square root is not rational.) For that matter, the 11th-century chakravala method amounts—in modern terms—to an algorithm for finding the units of a real quadratic number field. However, neither Bhāskara nor Gauss knew of number fields as such.

The grounds of the subject as we know it were set in the late nineteenth century, when ideal numbers, the theory of ideals and valuation theory were developed; these are three complementary ways of dealing with the lack of unique factorisation in algebraic number fields. (For example, in the field generated by the rationals and , the number 6 can be factorised both as and ; all of 2, 3, and are irreducible, and thus, in a naïve sense, analogous to primes among the integers.) The initial impetus for the development of ideal numbers (by Kummer) seems to have come from the study of higher reciprocity laws,^[12] i.e., generalisations of quadratic reciprocity.

Number fields are often studied as extensions of smaller number fields: a field L is said to be an extension of a field K if L contains K. (For example, the complex numbers C are an extension of the reals R, and the reals R are an extension of the rationals Q.) Classifying the possible extensions of a given number field is a difficult and partially open problem. Abelian extensions—that is, extensions L of K such that the Galois group^[13] Gal(L/K) of L over K is an abelian group—are relatively well understood. Their classification was the object of the programme of class field theory, which was initiated in the late 19th century (partly by Kronecker and Eisenstein) and carried out largely in 1900—1950.

An example of an active area of research in algebraic number theory is Iwasawa theory. The Langlands program, one of the main current large-scale research plans in mathematics, is sometimes described as an attempt to generalise class field theory to non-abelian extensions of number field

what is Technology

Technology is the making, usage, and knowledge of tools, machines, techniques, crafts, systems or methods of organization in order to solve a problem or perform a specific function. It can also refer to the collection of such tools, machinery, and procedures. The word technology comes from Greek τεχνολογία (technología); from τέχνη (téchnē), meaning "art, skill, craft", and -λογία (-logía), meaning "study of-".^[1] The term can either be applied generally or to specific areas: examples include construction technology, medical technology, and information technology.

Technologies significantly affect human as well as other animal species' ability to control and adapt to their natural environments. The human species' use of technology began with the conversion of natural resources into simple tools. The prehistorical discovery of the ability to control fire increased the available sources of food and the invention of the wheel helped humans in travelling in and controlling their environment. Recent technological developments, including the printing press, the telephone, and the Internet, have lessened physical barriers to communication and allowed humans to interact freely on a global scale. However, not all technology has been used for peaceful purposes; the development of weapons of ever-increasing destructive power has progressed throughout history, from clubs to nuclear weapons.

Technology has affected society and its surroundings in a number of ways. In many societies, technology has helped develop more advanced economies (including today's global economy) and has allowed the rise of a leisure class. Many technological processes produce unwanted by-products, known as pollution, and deplete natural resources, to the detriment of the Earth and its environment. Various implementations of technology influence the values of a society and new technology often raises new ethical questions. Examples include the rise of the notion of efficiency in terms of human productivity, a term originally applied only to machines, and the challenge of traditional norms.

Philosophical debates have arisen over the present and future use of technology in society, with disagreements over whether technology improves the human condition or worsens it. Neo-Luddism, anarcho-primitivism, and similar movements criticise the pervasiveness of technology in the modern world, opining that it harms the environment and alienates people; proponents of ideologies such as transhumanism and techno-progressivism view continued technological progress as beneficial to society and the human condition. Indeed, until recently, it was believed that the development of technology was restricted only to human beings, but recent scientific studies indicate that other primates and certain dolphin communities have developed simple tools and learned to pass their knowledge to other generations

Common sense for smart phone security

Smartphones have done wonderful things for employee mobility, but they have also complicated the security picture at organizations large and small. Where most companies used to limit smartphone use to one platform, such as Research In Motion’s Blackberry, most now cope with multiple smartphone models, platforms, and operating systems, each with its own quirks and vulnerabilities. Add the growing number of employees expecting to use the same device at home and work and things get even dicier.

However, there are steps you can take to secure smartphone use. As usual, they involve education, policy, and technology.

If you allow multiple smartphone platforms, such as iOS, Android, and Windows 7, it’s important to educate users on the security challenges these devices bring to the organization and the proper measures users must take to address them. Users should be educated about the dangers of device theft, data theft, data leakage, and malware and the financial impact they can have on the business. Include some actual use cases and anecdotes that demonstrate just how damaging smartphone breaches can be, and keep users aware of publicized, damaging breaches as they come up. Education should be repeated at least once a year and new employees should be educated immediately to the dangers as well as the company policies related to mobile devices.

Policy is the second obvious defense. Most policies should at least require users to:

• Keep smartphones within their sight at all times
• Activate phone locking after a period of inactivity and use strong passwords or PINs for reactivation
• Back up smartphone applications and content regularly
• Report smart phone theft immediately so remote locking or remote wiping can be activated
• Avoid using smartphones over insecure Wifi networks
• Connect from smartphone to the corporate network over secure VPN’s
• Encrypt all corporate information stored on the phone using provided tools
• Keep Bluetooth out of discovery mode when not in use
• Avoid clicking on links in SMS messages
• Make it clear that no jailbroken phones will be allowed in the organization.

When it comes to malware, things get a bit more complicated. Some smartphone platforms have malware protection software available and some don’t. Even for those that do, the applications are relatively new.

One way to reduce the threat of malware is to educate users on what to look for when downloading new applications. For example, Android displays all the permissions a new application is seeking on the device. Users should be taught to look out for applications that seek access to things like contacts or location unnecessarily and to carefully read user application ratings before downloading. Some companies might want to provide their own online store of pre-approved applications. Users should submit any other applications to the store minders to ensure their safety.

Make Yours A First Rate Job With Teng Tools

When anyone attempts a job, maintenance work or possibly a construction project, they really want the result to be the very best that it can possibly be. When the ideal outcome is not attained after much effort has been invested, one can be left feeling negative and hopeless. This would be an awful shame, and in some cases where such things happen, the blame does not lie with the workman for not working correctly. Often, most of the hard work dedicated to a project can be perfectly executed and the result may still be far from perfect. What’s the reason behind this? This could commonly occur because of tools being used which are simply unsuitable to do the job in hand or they may be of a low quality. This may be a horrendous shame if the only thing stopping the required result being achieved with a job would simply be the type of tool used. So what is the solution to ensure that the tool you select is suitable for the job in hand and is of a sufficient quality to finish a job to a high standard? This can be attained through using Teng tools.

Some of the best quality tools available today are produced and distributed by Teng tools.

Renowned Steve Jobs Passed Away

yesterday’s announcement of the iPhone 4S, Apple co-founder and former CEO Steve Jobs has died. Jobs had fought a long battle with a rare form of pancreatic cancer, and after seeking treatment across the world, he has fallen to the illness at the age of 56.

Jobs passed away today, October 5, just one day after the debut of the next generation iPhone. The iPhone, introduced in June of 2007, launched the mainstream smartphone revolution and is arguably Jobs’ greatest achievement at Apple.

According to Apple’s official website: “Apple has lost a visionary and creative genius, and the world has lost an amazing human being. Those of us who have been fortunate enough to know and work with Steve have lost a dear friend and an inspiring mentor. Steve leaves behind a company that only he could have built, and his spirit will forever be the foundation of Apple.“

How To Build Your Own Social Network

After facebook started in 2004, it swiftly grew to become a large success and it now has many million members. Only one web site is currently rated higher than facebook on alexa's list of top web pages, the number one is google. Quite a lot of the online traffic is centered around social network sites, and lots of newbies, site owners and companies would like to figure out how to setup a social networking site.

When building a social network, you can more or less use three different approaches. The first and least difficult solution is registering with a social network service which will allow you to setup your social network by just editing your social network settings. This doesn't demand any technological knowledge, so if you are not a computer savvy individual, this might be the best choice. One can find free services out there, however I do not suggest selecting them because you should really buy your own domain name. The starting price for a great platform is about 20$ monthly, however depending on exactly what functionality you desire, you may have to pay more.

Another method you can use is getting a social networking script or downloading an open source software that you set up on your hosting server. The most popular open source social networking software is elgg, that you can download at no cost. The commercially made social networking applications range in starting price from about 99$ to 397$ based on what sort of license and options you are looking for. Creating your social internet site using a software requires some technological knowledge. The advantages are that you are in full control of your own data and that the system is normally not encrypted and it is extensible.

I will not discuss in details how you can setup a social networking site using a script in this brief article, but listed below are the fundamental information:

1. Download your software to your computer
2. Extract the contents of the .zip file
3. Find a hosting company which have the correct features and pay for a web hosting plan
4. Add a new database to your web hosting account
5. Upload the social networking script with a FTP software to your web hosting account
6. Start the software's installation wizard
7. Alter the configuration settings of your social network script
8. Change the design of your social networking site or locate a template that appeals to you

The last option is choosing a coder which can build a tailor made solution for you. This will definitely cost more than paying for or finding an open source software that has already been created. The benefit is that your online community is going to be 100% unique and catered to your requirements. Almost all social networking scripts are unencrypted and extensible, so extending a script that has been developed and tested well before hand, will help save a lot of time and money creating the basic elements that most social sites have.

All the three methods mentioned that can be used to set up a social network has their advantages and disadvantages. When determining how to build a social networking site, you need to give consideration to the cost, if you have got the technical abilities needed, what features you are looking for and if you are in complete control of your database. Personally I would never use a service provider where you can't use your own domain and are not in full control of your files and database, as I would not want to risk losing my business if my provider went out of business.

Routers, To See Different Types of Routers

There are several types of routers you may hear of: wired router, wireless router.

More detailed classification: Internal router (IR): All interfaces belong to the same area; Area Border router (ABR): Interfaces to multiple areas; Backbone router (BR): Interfaces to backbone; Autonomous system boundary router (ASBR): Exchange routing info with other autonomous systems; Designated router (DR): Generates link-state info about the subnet; Backup designated router (BDR): Becomes DR if DR fails.

If you use computers in your home or office, it is likely that your computer is connected with other computers through some type of router. Like a police officer directing traffic at an interchange, a router will direct or route information, data and files to the locations they need to go. Generally, Routers that we used can either be wired or wireless.

A wired router will generally connect to your computer and computers or hardware through an Ethernet cable. This happens with the use of output ports. And the only input port provided on a router will be used for the Internet.

A wireless router may allow access from several computers through wired Ethernet cables and through wireless connections. You will know the router you are using is wireless if it comes with an antenna. The antenna will provide the router with a specific range that allows other computers in the area with wireless capabilities to access the router, provided they have password access.

Two Typical Routers We Usually Used

Commercial Router
If you have ever been to a coffee shop or hotel that offers Wi-Fi access, chances are they are using a commercial-grade router. These routers are much more powerful than what you would purchase at your local electronics or computer store. The best commercial routers will be able to provide access to the Internet, files and printing, for example, with little problem. Commercial routers may also be used by businesses, hospitals or in a university setting as part of a wide area network or WAN. (Cisco is a leading router manufacturer to aim to provide router and networking solution to small, medium and large enterprises) This is a network that allows computers to connect to each other even if they are in another building across town. The commercial-grade router will be used to connect with the wide area network (WAN) on one side and a smaller network called a local area network (LAN) on the other. The local area network may consist of one large office within a building. In that case, you could have multiple LANs connecting to the WAN through one or multiple routers.

Consumer Routers
If you are looking for a router for your home or small business, you likely can find what you need at your local electronics store. Generally you will want a router that serves as a wireless access point (WAP). It should also be a network switch. The wireless access point (WAP) basically provides the wireless access that everyone wants. That wireless access can be both to the Internet and to other computers in the home or office. Routers that come with a network switch tend to be faster and provide more evenly distributed bandwidth to each port. Consumer routers will come in a variety of price ranges and strengths. Some of the lower priced consumer routers will not have a very strong firewall. (Cisco Linksys E-series routers, powerful home routers, are welcomed by a lot of Cisco fans, more info of Cisco’ home product store you can visit Cisco’s official site: cisco.com).

Network Cabling the Arteries and Veins of the Body Electric

The vampire jack is a good name for one of the ways to insert data, the lifeblood of cyberspace, through cabling from one computer to another. The majority of computer networks use three classes of cabling: coaxial, twisted-pair (unshielded and shielded), and fiber-optic cable. Whether the computers and peripherals are networked by wireless or cable the flow of data will enter and leave the computers via the network adapter card. This article focuses on the uses of physical cabling connections and the variations in major cabling types.

Cabling surrounds us in our offices; much of it runs in the space between dropped ceilings and the structural ceilings so it can be extended down the walls and into the computers. Manufacturers make thousands of variations of cabling; only three major types connect the majority of networks: coaxial, twisted-pair (unshielded and shielded), and fiber-optic cable.

Coaxial cable consists of a copper core covered by a layer of foil insulation and braided metal shielding, and is referred to as dual shielded. In environments where there is unusually high interference there is coaxial cable with a second layer of foil insulation and another layer of braided metal shielding (quad shielding). The material that surrounds the solid copper core is meant to absorb stray electronic signals, or "noise" that would otherwise distort the data.

The outer protection from signal interference and electronic fields known as "crosstalk" from nearby wires is the braided shielding, or mesh. The transmitting copper core can't be allowed to come into contact with the metal mesh naturally or the metal-on-metal overflow of signals would cause a short circuit and destroy the data. To protect the copper wire, a layer of a thermoplastic polymer called Polyvinyl chloride (PVC) or Teflon is used. Over the core, insulation layer, and braided mesh of the cable there's a non-conducting outer shield of rubber or Teflon.

Coaxial cable is the workhorse of long-distance cabling because it doesn't suffer significant deterioration of the signal strength; this made the introduction of cable TV networks possible and practical for widespread use due to its ability to carry large data rates. When signal strength gets weaker and weaker over the distance of the cabling the technical term is attenuation. Any network cabling plan would take into consideration the quality of signal strength and amount of data to be transmitted.

A thick type of coaxial cable, or "thicknet" is used as the standard for heavy-duty connections where outside elements may damage wiring. There is also a thinnet coaxial cable about a quarter of an inch, that's more flexible and easy to work with in any kind of network cable installation. The thinnet center can be stranded wire or solid copper core; the signal attenuates past 185 meters so it is use for short connections.

Twisted-Pair cable is made up of two insulated copper wires twisted around each other; they also have unshielded and shielded types. An example of unshielded twisted-pair cabling is plain old telephone line. The twisting of the wires cancels out noise from other wires and nearby objects emitting electronic signals like motors or transformers. Like coaxial cable, the data isn't secured because it can be tapped and the data stolen.

In situations that involve more than just stealing the neighbor's cable, fiber-optic cable provides high-speed modulated pulses of light to send the data instead of electrical impulses. The data transmission is high-quality, extremely fast, and free of attenuation. Fiber-optic cable has a sending strand and a receiving strand. The core of each strand is made of extremely thin glass, surrounded a concentric glass layer called cladding. The complete cable is two stands covered by a protective jacket to give it sending and receiving capability.

Each type of network cabling has specifications for use and fire ordinance information to observe. Regular home and office standard cable connectors are familiar to most. Special care should be taken to have the correct configuration of the network adapter card; this can be a network adapter, a network interface card (NIC), a LAN adapter, or an Ethernet Controller. Ethernet defines a number of wiring and signaling standards for the physical layer of the standard networking model; Ethernet cable standards use all three cable types.

Speed of data transmission in megabits per second increases with technological breakthroughs to keep our computer networks humming along communicating efficiently while we as mere humans are left standing at home or in the office with our hands full of bunches of unfamiliar squid-like colored cables with strange-looking connectors, desperately trying to find which holes they go into.
