Socket

Overview

Sockets are an endpoint for sending and receiving data across a computer network. They enable communication between different processes, either within the same machine or over different machines. Sockets are a key concept in network programming and are used extensively in internet communications.

Types of Sockets

There are two main types of sockets:

Stream Sockets

• Protocol: Typically use Transmission Control Protocol (TCP).
• Characteristics:
  • Connection-oriented.
  • Data is read in a continuous stream.
• Use Case: Ideal for scenarios where reliable communication is crucial, like file transfers or sending/receiving messages in chat applications.

Datagram Sockets

• Protocol: Usually employ User Datagram Protocol (UDP).
• Characteristics:
  • Connectionless.
  • Data is read in chunks (datagrams).
• Use Case: Suited for applications where speed is more critical than reliability, such as online games or streaming services.
