What is a Port in Networking Definition

The computer ports or connectors are used to connect various devices to a computer system with the help and assistance of a computer motherboard.

These ports can connect a mouse, keyboard, hard disk drives, DVD-RW, Printers, and Monitors,

In other words, “PORT” can be defined as a physical location on a computer system used for data exchange.

In networking, the Port is basically used to send and receive data and information over networks, usually named “Transmission Control Protocol”.

Common Ports are

  • 80 – HTTP (Web browsing)
  • 443 – HTTPS (Secure web browsing).

Data exchange and information can be shared using ports in networking.

A port is an identifier for a physical connection on a computer, router, or switch.

It’s used to identify the network adapter card (NIC) where the Port is located and its associated properties.

Two Types of Ports in Computer Networking.

  1. Physical Ports.
  2. Virtual Ports.
