TCP/IP Model and TCP/IP suite

TCP stands for Transmission Control Protocol, and IP stands for Internet Protocol. TCP/IP is used for both a protocol suite and a networking Model.
The TCP/IP suite, or simply the Internet protocol suite, refers to a group of protocols used on modern networks. These protocols work together to provide an end-to-end connection by specifying how data should be segmented, addressed, and routed across networks.
The TCP/IP Model has four layers: Application, Transport, Internet, and Link.
