It can be either connection-oriented or connectionless. On the whole, a socket is a way to establish a connection between a client and a server. 6 | 7 |

what is a Socket ?

10 | 11 | A socket is one end-point of a two-way communication link between two programs running on the network. Socket classes are used to represent the connection between a client program and a server program. The java.net package provides two classes--Socket and ServerSocket--that implement the client side of the connection and the server side of the connection, respectively. 12 | 13 |
14 | 15 | ## Definition: 16 | 17 | "A socket is one endpoint of a two-way communication link between two programs running on the network. A socket is bound to a port number so that the TCP layer can identify the application that data is destined to be sent to." 18 | 19 | 20 | - Oracle docs - 21 | 22 | 23 | 24 | ![Screenshot (1056)](https://user-images.githubusercontent.com/100486080/182596076-98a473d2-d81a-4964-b8a7-f8d07f853f69.png) 25 | 26 |
