What Is Network Port?

Regarding networks, a port might be compared to an entrance or exit. A network port enables data to enter and leave your network like a building doorway allows people to enter and leave the building. A network port is a "hole" in your computer network that facilitates communication between individual devices.

Take, for instance, the scenario in which you are attempting to visit a website using your personal computer. After you have typed in the website address, your computer will request the network to connect to the website's server.

There are numerous varieties of ports, each serving a distinct function in the world. For example, HTTP uses port 80, HTTPS uses port 443, and FTP uses port 21. These are known as well-known ports and are typically utilized to operate particular services and protocols. However, just like not everyone enters a building by the main entrance, not all data goes in and out of the building through the commonly known ports. It will occasionally use a separate port, which is referred to as a dynamic or private port. These ports are typically used for making temporary connections, and the numbers they can be assigned range from 49152 to 65535. The ports' level of safety is an additional vital component. In the same way that a building's security guard examines identification cards to ensure that only authorized
