TCP/IP, short for Transmission Control Protocol/Internet Protocol, currently in its fourth revision known as IPv4, and sometimes referred to as 4bone, serves as a communication framework used to transmit data across networks. It stands as the primary protocol governing the operation of the Internet.

TCP/IP comprises a collection of directives that outline the process of sending data packets across various networks. The TCP segment manages the confirmation of packet delivery, while the IP segment is responsible for the routing of data packets between nodes.
