What is Sockets?

Categories: Python

Sockets are the endpoints of a bidirectional communications channel. Sockets may communicate within a process, between processes on the same machine, or between processes on different continents.

Sockets may be implemented over a number of different channel types: Unix domain sockets, TCP, UDP, and so on. The socket library provides specific classes for handling the common transports as well as a generic interface for handling the rest.

Sockets have their own vocabulary −


Sr.No.Term & Description

1. Domain - The family of protocols that is used as the transport mechanism. These values are constants such as AF_INET, PF_INET, PF_UNIX, PF_X25, and so on.


2. type - The type of communications between the two endpoints, typically SOCK_STREAM for connection-oriented protocols and SOCK_DGRAM for connectionless protocols.


3. protocol -Typically zero, this may be used to identify a variant of a protocol within a domain and type.


4. hostname - The identifier of a network interface −

A string, which can be a host name, a dotted-quad address, or an IPV6 address in colon (and possibly dot) notation

A string "<broadcast>", which specifies an INADDR_BROADCAST address.

A zero-length string, which specifies INADDR_ANY, or

An Integer, interpreted as a binary address in host byte order.

5. port - Each server listens for clients calling on one or more ports. A port may be a Fixnum port number, a string containing a port number, or the name of a service.
