What is Internet?

The internet is a chain of interconnected computer networks using the standard internet protocol suite (TCP/IP). This chain is comprised of web servers and client computers. Clients are computers that access this network through an internet connection. Web servers handle the actual web pages. Web servers have a bunch of web sites loaded waiting for clients to request them, which is done through browsers such as Internet Explorer, Firefox, Opera, etc.

The Internet is a network of networks, spread over the whole globe. The foundations for the origin of the Internet were laid back in the 1960s when the United States funded research projects of its military agencies to build robust, fault-tolerant and distributed computer networks. Initially, the network was known as ARPANET, which later became the internet when its capacity was increased with the connection of more number of computers to the network.The Internet has no centralized governance in either technological implementation or policies for access and usage.

The most important component of the Internet is the Internet Protocol (IP), which provides addressing systems (IP addresses) for computers on the Internet. The IP address is a unique naming convention of each and every computers that are part of the Internet.

The Internet has been serving everyone around the world, with every possible means. E-mail is an important communications service that is available on the Internet. The concept of sending electronic text messages among the people similar to the mailing letters or memos predates the creation of the Internet. File sharing helps to send and receive large sized files across the globe. The Internet has also enabled entirely new forms of social interaction, activities, and organizing, through social networking sites such as twitter, facebook, myspace, etc.
