Importance of Internet and Its Services

The Internet has gained popularity and emerged as an important and efficient means of communication. The idea of introducing the internet was to allow millions of people to share information and ideas, sound, video clips using their computers across the world. The internet is a world wide network of networked computers those are able to exchange information with each other. It consists of thousands of separately administered network of various sizes and type.

Internet:
Internet stands for International Network, which began in 1950's by Vinit Curf known as the Father of the Internet. The term Internet is derived from two words-Interconnection and networks, also referred to as "Net". Internet is a "network of networks" that consists millions of private and public network of local to global scope. Basically, network is a group of two or more computer systems linked together.

Uses and Working of Internet:
Internet has been the most useful  technology of the modern time which helps us not only in our daily lives but also our personal and professional lives developments. Internet helps us in communication, information, business, social networking, shopping, entertainment, job searching and E-commerce.

The computers on the Internet are connected to each other through the small networks.These networks connected through the gateways to the Internet backbone. The data move around the Internet is controlled by protocols. Under TCP/IP protocol (Transmission Control Protocol / Internet Protocol), a file is broken into smaller parts by the file server called packets. All computers on the Internet, communicate with one another using TCP/IP, which is a basic protocol of the Internet.

History of Internet:
In 1969, the university of California at Los Angels. the University of Utah were connected as the beginning of the ARPANET (Advanced Research Projects Agency Network) using 50 kbits circuits. It was the world's first operational packet switching network. The goal of this project was to connect computers at different universities and U.S defence.

In mid 80's another federal agency, the National Science Foundation, created a new high capacity network called NSF net, which was more capable than ARPNET. The only drawback of NSF net was that it allowed only academic research on its network and not any kind of private business on it. So, private organisations and people started working to build their own networks, which were later interconnected with ARPNET and NSF net to form the Internet.
