Wiki link to network sockets: https://en.wikipedia.org/wiki/Network_socket

A TCP/IP Network Socket consists of three things:

• An IP address
• Transport protocol
• A port number

For example:
(10.50.1.2, TCP, 80) is a socket.

A socket is a connection between client (your laptop, PC, etc) to a remote server, for example running a web server on port 80.

Your computer will send and receive data via these sockets.

As the wiki link details, there are more than one type of socket.
