Hi,
Port 80 is the port reserved for the http protocol. Almost all ports between 01 and 1024 are reserved for specific protocols or actions. The alternative port for the http protocol is port 8080, so it is reserved for possible use by Wampserver.
If you want to use particular ports, you have a choice between 1025 and 65535, but, whatever port you choose as an alternative port, it must be declared as a listening port by Apache. The simplest way to do this and the easiest way to check for Wampserver is to use the Apache variables.
