TCP/IP (an acronym for Transmission Control Protocol/Internet Protocol) is a software-implemented protocol for connecting different networks to each other. The TCP component of the suite controls the disassembly and reassembly of data packets sent from a computer server, where the data resides. The IP component specifies the formatting and addressing scheme for transmitting data between sender and recipient computers. The software that implements the TCP/IP protocols is typically included as part of the operating system.
