TCP/IP stands for Transmission Control Protocol/Internet Protocol and is a suite of communication protocols used to interconnect network devices on the internet. It is a framework for organizing the set of communication protocols used in the Internet and similar computer networks according to functional criteria. TCP/IP is also used as a communications protocol in a private computer network (an intranet or extranet) . The entire IP suite is commonly referred to as TCP/IP, and TCP and IP are the two main protocols, though others are included in the suite. The TCP/IP protocol suite functions as an abstraction layer between internet applications and the routing and switching fabric.

TCP defines how applications can create channels of communication across a network. It also manages how a message is assembled into smaller packets before they are then transmitted over the internet and reassembled in the right order at the destination address. TCP is a connection-oriented protocol that addresses numerous reliability issues. It enables data to be transferred between applications and devices on a network and is used in the TCP/IP model.

IP is responsible for obtaining the address to which data is sent, and TCP is responsible for data delivery once that IP address has been found. The TCP/IP model divides its data into packets to ensure that each message reaches its final destination accurately. TCP/IP puts a lot of emphasis on accuracy, and it has several steps to ensure that data is correctly transmitted between the two computers.

In summary, TCP/IP is a suite of communication protocols used to interconnect network devices on the internet and is responsible for data delivery and obtaining the address to which data is sent.
