TCP Communication

TCP (Transmission Control Protocol): TCP provides reliable, connection-oriented transport services for high-reliability data transmission. The reliability of TCP protocol is to ensure that each TCP message can reach the client in the order of sending.

The TCP communication process is generally the following steps:

A) server-bound port, waiting for client connections.

b) The client connects to the server through the server's IP and server-bound ports.

c) The server and client set up a data path through the network to interact with the data through this data path.
