What is TCP Port?

Port is a 16-bit unique number that identifies  a specific software program on the server system. Ports are unique identifiers. For example, port 80 represents Web Server (HTTP) , port 21 represents FTP server and port 25 represents SMTP server. Without port numbers, the server system would have no way of knowing which application a client wanted to connect to. So, ports are just numbers that representing a server application. A server can have up to 65536 (0-65535) server application running. A TCP port numbers from 0 to 1023 are reserved for specific applications. Don't use these ports for your own custom server programs.
