BIOS interrupt call

So, imagine that you have a big toy box with lots of different toys in it. But you really want to play with a specific toy that's in the very bottom of the box. You could dig through all of the other toys and try to find it yourself, but that would take a long time and you might even miss it.

Instead, you ask your mom or dad to help you out. You tell them what you want and they go through the box, find the toy you asked for, and give it to you.

That's kind of like what a BIOS interrupt call is. Your computer has a bunch of different programs and functions that it can perform, but sometimes you want to use a very specific one that's buried deep inside the computer's memory.

By making a BIOS interrupt call, you're telling the computer's BIOS (Basic Input/Output System) to go find that specific function and run it. That way, you don't have to sift through all of the computer's programs and functions yourself - the BIOS will handle it for you.

Overall, a BIOS interrupt call is just a way to ask your computer's BIOS to perform a specific function or task, so you don't have to do it manually.
