What is a Port Number?

To put it simply, a port number is the means through which a specific message is identified when it’s forwarded to a server. Depending upon on the service type, it will either be associated with TCP or UDP port.

TCP vs. UDP

TCP stands for Transmission Control Protocol and sends the data after establishing a connection which makes it more reliable than UDP for data transfers. On the other hand, UDP stands for User Diagram Protocol and sends data packets connection-less which makes it lightweight and significantly faster than TCP.

What is the Difference between an IP Address and Port Number?

A computer network is made up of a collection of devices – such as routers, printers, laptops, and cameras – that are connected together for sharing data and resources.

Each device within the network has a unique numerical label allocate to it, known as the Internet Protocol (IP) address. It helps with two main functions:

• Network or host identification
• Location addressing

In contrast, a single device can have multiple processes running at any given time. The port number is what helps to identify those processes taking place in the device.
