There are three types of port in the computer / internet world:

  • A port is a physical access point for a computer – a small socket that acts as an interface for a link (such as a cable) to another device such as a mouse.
  • A port can also be virtual – it is represented by a number (the number 80 identifies webpage traffic) and points packets (small amounts of data) to the correct network application.
  • You can port an application or software to another computer – this will involve rewriting some of the code so it works on the new computer.
