What do file extensions (exe, pdf, etc) actually do?
In: Technology
Imagine you are a teacher and you enter a classroom full of kids who want to go to the bathroom. You know which bathrooms to direct them to (boys/girls), but don’t know which kid is which. So you ask them to identify themselves. When they say „boy“ you direct them to the boys washroom and when they say „girl“ you direct them to the girls washroom.
Extensions are like that, but for computers. Extensions is the kid identifying itself. Teacher is the computer.
It will tell the computer useful information – which helps the computer decide how to handle it (For example what program to open it with etc)
