Abstraction

Abstraction is thinking about things in a simpler way. It's like making something simpler so that it's easier to understand. For example, a computer has lots and lots of parts that all work together, but when you use the computer, you don't have to think about all of those parts, you just use it in a more abstract way. That way, the parts of the computer are "abstracted away" so that it's easier to understand how to use the computer.
