Ports can be used for whatever a person may choose to host on them, so long as the connection between the client and server on a given port uses a consistent protocol. While ports make it simple to identify and address specific requests, port-numbering conventions are a standard, not a rule. If you are viewing this guide on the internet and using a web browser, you're probably connected using HTTPS, which operates over port 443.

80 : HTTP (Hypertext Transfer Protocol).

25: SMTP (Simple Mail Transfer Protocol).

Some commonly used ports are shown below. Ports are generally associated with specific services, such that a client can connect to a server on a particular port and assume that the server will accept a connection at that port and respond appropriately.

Different ports can be used simultaneously to separate and parse different types of traffic or requests easily. Networked services and apps running on various devices make use of ports at specific numbers as a means to initiate connections and establish communications.

To overcome the issue, port forwarding can be used to make these devices publicly accessible. While servers with dedicated IP addresses can connect directly to the internet and make ports publicly available, a system behind a router on a local network may not be open to the rest of the web. Ports allow network and internet-connected devices to interact using specified channels.
