Port 80
port 80
By default, most web servers are run on port 80. You can change this in the server's configuration file to something else, but then a web browser may have trouble accessing it.
A Web server - or most other servers - will HAVE TO reserve a port number, to function correctly. For a Web server, this is usually port 80, but this can be changed to any other port.A Web server - or most other servers - will HAVE TO reserve a port number, to function correctly.

1) On the server side, to distinguish different applications. Thus, if the server (the server computer) receives a data packet for port 80, it will usually be forwarded to the Web server; but if it receives a data packet for port 21, it will be forwared to the FTP server. 2) On the client side, to distinguish different conversations. For example, if the browser accesses two files from the same Web server at the same time, the first file might be assigned, for example, port 1024 (for the sending port; the receiving port will be 80), while the next file might be assigned port 1025. When a data packet is sent back for port 1025, in this example the browser knows that it is for the second file.
Port 80
Conventionally, an HTTP server listens on port 80. Regardless of the brand of web server that you are running, the server will typically listen for HTTP traffic on port 80 and HTTPS traffic on port 443.
You would access in the form of: http://<server-address>:<port>/ An example would be http://localhost:8080/

A port number is a kind of address within a computer. It helps distinguish different services on a server. Thus, any data that goes to port 80 (TCP) will be processed by the Web server; data for other ports gets sent to other applications.On the client side, the port number helps separate different "conversations". For example, if I load different Web pages at the same time, in my browser, one might be assigned to port 1024, the next to port 1025, etc. This is the origin port; the destination port is still port 80. But when data comes back from the server, my computer will receive it at port 1024, or port 1025, and thus know to which file the information must be added.A port number is a kind of address within a computer.
