The Internet began in the late 1960s as a network developed by the US Department of Defense to allow communication even if parts were damaged. In the 1980s, the NSFNET allowed researchers to share data. Now many networks are connected, forming the global Internet. Computers communicate using TCP/IP protocols. While the Internet provides advantages like email and information access, it also poses disadvantages like security and privacy risks from hacking, viruses, and cookies that can damage data. Organizations like ISOC and IETF work to support and coordinate Internet development and standards.
