Q1. What is an Internet? How it differs from Intranet? Explain the various Internet Tools. Ans: INTERNET No discussion on communication would be complete without discussing the Internet, referred to by its millions of users as the Net. So what does Internet mean? Is it same as what we call network? The answer is no. The network is interconnection of two or more computers and Internet is a network of networks.

The Internet evolved from ARPANET, a research network created in the 1960’s by the Defense Department and the National Science Foundation (NSF) to link research institutes and government agencies around the world to exchange information on a wide range of topics. Although the original ARPANET no longer exists, its design and architecture laid the foundations for the Internet.

People all over the world can search the net for information; add new information, and exchange views on different topics.

telnet, and FTP. However, the network and its resources are used privately by businesses and are not available to people outside the company. An Intranet is separated from rest of the Internet by a Firewall. People who work in the company can access the Internet and use its resources, but intruders are kept out of the firewalls. An Intranet, therefore, can be defined as a private system that uses the hardware and software developed for Internet to provide communication, information management, and information publishing services within an organization.
