Define and discuss the Internet
What will be an ideal response?
The Internet (short for interconnected network) is a global network of networks connecting innumerable smaller networks, computers, and users. It is run by a committee of volunteers; no one owns or controls it. The Internet originated in 1969 as ARPAnet, a project of the Advanced Research Projects Agency of the U.S. Department of Defense. The Department of Defense was attempting to create both a national network of scientists and a communications system that could withstand a nuclear attack. The network was, therefore, to be decentralized, forming a communications web with no central authority. The protocol that eventually governed ARPAnet and continues to govern the Internet today is public domain software called transmission-control protocol/Internet protocol (TCP/IP).
