Think of a computer as a block of flats and a port as each pigeon hole. You connect to the computer but then you have to decide what service you want from that computer. For example you can get web (HTTP) on port 80 or FTP on port 21. These port numbers can be changed by those are the defaults.

Basically when you have lots of different programs running on one server you need to have a way of saying which program you want to speak to.
