ELI5: Explain Like I'm 5

Patch (Unix)

So, you know how sometimes you have a shirt with a hole in it, or maybe a toy with a tear? Well, you can try to fix it with a patch!

On a computer, there are programs that are made up of a lot of different parts, just like how a shirt can be made up of different pieces of fabric. Sometimes, there might be a problem with one of those parts, like a bug (which is like a little error or mistake).

Just like how you might use a patch to cover up a hole in your shirt, programmers can use a "patch" to fix a problem in their program! A patch is a little chunk of code that can be put into a program to fix a specific problem.

This can be really helpful because sometimes the problem is small and only affects a few people, or maybe the programmers just found out about it after they released the program. Instead of having to make everyone download a whole new version of the program, the programmers can just release a patch that fixes the problem.

So, just like how a patch on your shirt can save you from having to buy a new one, a patch in a program can save you from having to download a whole new version!
