I want to know about the ports used in xampp

Question

We use port in xampp but i cant understand the use of it can anyone answer me?
For what they r used and whether we should use a particular port for particular language like php.

Answer 1

A port is the mean of communication in an operating system. And clearly every port is a way of communicating for a specific kind of program(or process) and practically we say that the p1 program listens to some specific port number meaning that this port number is the program's way of communicating...
By default, the port that Xampp listens to is 80.
If there is a conflict in your OS(meaning that something else is listening to that port), you need to change that some port that is not being used by any other program. Refer to the below link to see how:
