Bit blit

Okay, let's imagine you have a picture that you want to move somewhere else on your computer screen. Bit blit is like picking up that picture and moving it from one spot to another.

But how does it work?

Well, your computer has a memory that stores information about what's on your screen. When you move the picture, the computer takes a little piece of that memory (called a "bit"), and copies it to a new spot on the screen (which is why it's called "blit", like "blink" but with a "t"). The computer keeps doing this for all the bits that make up the picture, until it's in its new spot.

It sounds simple, but bit blit is actually a really important part of how your computer works. It's used for all kinds of things, like drawing shapes on the screen or scrolling through a web page. And it happens so quickly that you don't even notice it's happening in the background!
