What is a Port Number?

To put it simply, port numbers allow applications on the same computer to share network resources simultaneously. Depending upon on the service type, it will either be associated with TCP or UDP port.

 

Difference Between UDP and TCP ports

TCP Ports: TCP stands for Transmission Control Protocol. This method sends the data after establishing a connection which makes it more reliable than UDP, at least for data transfers.

UDP Ports: UDP stands for User Diagram Protocol. With this method, it sends data packets without a need to establishing a connection at first, which makes this protocol faster than TCP.

 

What Is The Difference Between An IP Address And Port Number?

An IP address is your device’s address on the network. Think of a port as a location in that address.

To put it simply, when you communicate over a network or the Internet, your PC is identified by an IP address, usually IPv4 or IPv6. That’s how you can browse the Internet, or access to resources on a server across an internal network.

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