The Internet offers a unique ability so broad and powerful that it can be utilized for any purpose that greatly depends on data, and anybody who associates with one of the many constituent networks has access to it. It supports human interaction through electronic mail, chat rooms, forums, social networking, and online collaboration, and enables individuals to work together at a variety of locations. This means that many companies have an Internet presence, and this fact alone makes the Internet a very powerful medium. Businesses use the Internet as a way to reach a wider audience than they could otherwise and are able to do so at a cheaper and more effective scale than they might be able to achieve through other methods.
The cost of the Internet itself is also a major factor in why so many individuals and businesses are so eager to use the Internet. The cost of setting up a basic Internet connection is relatively low, particularly when you consider what you get out of such a commitment. However, the cost of maintaining an Internet connection of any kind — cable, DSL, or satellite — can quickly add up. In order to protect their subscribers from these rising costs, risks have developed a set of rules known as “network maintenance” which all users must adhere to in order to keep the Internet running smoothly and reliably.
When it comes to Internet connectivity, two types of Internet are usually defined: the local area network (LAN) and the wide area network (WAN). The former is the familiar ISP connection you get when you enter your home; the latter is a much larger area network that covers the entire country, often including the Internet backbone. An ISP service provider usually develops a separate Internet network for residential customers and a separate Internet network for business customers. The former includes the Internet service providers’ own internal switches and routers, whereas the latter refer to public switched telephone networks (PSTN) or commercial backbone connections. The backbone technically serves as a backbone for the entire Internet, but this is an oversimplification.
As far as the Internet goes, there are several major components. For example, all computer networks maintain a “home” directory, a group of mirrors (clients), and a collection of stored passwords. The configuration of the home directory and stored passwords dictate how Internet data is stored on a user’s computer. On a more complex level, e-mail services and web mail services (commonly referred to as “web mail”) are other important components of the Internet that are maintained by Internet service providers.
The final component of the Internet is VoIP, which stands for Voice over Internet Protocol. This technology provides IP-based voice communication between end-to-end using a broadband Internet connection. VoIP allows individuals and companies to make voice calls over the Internet without using traditional phone networks or public switched telephone networks (PSTN). VoIP can either be used internally (within the same network) or externally (on an external network). An example of an externally sourced VoIP service is ; a successful internal Skype service has to be configured such that it can accommodate as many clients as possible.
With all of these components, it seems that an overall description of Internet technology does not adequately represent the true nature of the Internet. In order to get a full picture, one must view all of these components not just in isolation, but from the perspective of a comprehensive network diagram. This is done by looking at the way routers route packets of data, as well as how various Internet service providers to configure their own routing table. A comprehensive graphical representation of how the Internet works can help Internet users and developers better understand the Internet and its workings.
