COMPUTER NETWORKING

Detailed explanation-1: -TCP/IP enabled an interconnected network of networks and is the foundational technology of the internet. On Jan. 1, 1983, TCP/IP replaced NCP as the underlying packet-switching technology of ARPANET. Also, in 1983, ARPANET was divided into two networks between military and civilian use.

Detailed explanation-2: -TCP/IP is a family of communication protocols used to connect computer systems in a network. It is named after two of the protocols in the family: Transmission Control Protocol (TCP) and Internet Protocol (IP). Hypertext Transfer Protocol (HTTP) is a member of the TCP/IP family.

Detailed explanation-3: -TCP/IP is responsible for full-fledged internet data connectivity and transmitting the data end to end by providing other functions, including addressing, mapping and acknowledgment. TCP/IP contains four layers, which differ slightly from the OSI model.

Detailed explanation-4: -Known as an IP address, the number can be used to find the location of any Internet-connected device in the world. After the introduction of TCP/IP, ARPANET quickly grew to become a global interconnected network of networks, or ‘Internet’.
