Sockets are also commonly referred to as "sockets," which describe IP addresses and ports, and are a handle to a chain of communication, where applications usually make requests to the network through "sockets" or respond to network requests.

Sockets originate from UNIX, and one of the basic philosophies of unix/linux is "Everything is file", and the file is operated with "open" "Read and Write" "Off" mode. Socket is an implementation of this pattern, the socket is a special kind of file, some of the socket function is the operation of it (read/write Io, open, close)

The difference between a socket and file:

• The file module is "open", "Read and write" "Close" for a specified document
• The socket module is "open", "Read and write" "Off" for server-side and client sockets
