What are the ‘ports’ in FTP or other linked computer connections representing/how do they work? What is their purpose and how do you determine which port number you need?
In: Technology
Your IP Address is the address of your computer, just like a building has a street address. The port is like the apartment number inside the building.
You have Chrome open to browse Reddit and you are playing an online game. Each of those two uses a different port number, so that data sent over the internet to your computer gets to the correct apartment, or program.
So a port number is literally just an extra number in the data being sent so the computer will know which program that data is for.
