Web server ports are the logical endpoints of a network connection that is used to exchange information between a web server and a web client. These ports are assigned a unique number to identify them separately. Port 80 and 443 are the two standard ports used by web servers to communicate with the web clients.
When data is exchanged through the Internet between a web client and a web server, they need to establish a mutual connection between them. To form this mutual connection, both the web client and the web server need to adhere to the same set of rules which is called a protocol. The standard protocols created for transmitting web content between a web server and a web client are the hypertext transfer protocol (HTTP) and the hypertext transfer protocol secure (HTTPS).
The HTTP utilizes port 80 to format and transmit web content from a web server to a web client over the Internet. This is the port used by your computer when you load web content such as a web page, videos, images and animations using your browser.
The HTTPS is an extension of HTTP which runs on SSL (Secure Sockets Layer) of the computer network. HTTPS utilizes port 443 for communication. This is the port used by your computer when you log into a secure web page using your credentials such as your username and password.
