We just learned about the Processor.

Another part of a computer is Memory.

When a processor is doing the work for a computer, sometimes it needs to a place to keep information while it is doing some work.
Kind of like if you are working on a big math problem, you might need to write down some of the parts of the problem before you are finished with the whole problem.

If you had the problem 10 + 20 + 30 + 40, you might right down the answer for 10 + 20 = 30, and then the answer for 30 + 40 = 60, and then 30 + 60 = 90.
Those middle steps where you have to write down the 30 and the 60 are not part of the math problem and not part of the answer, so they are sort of like middle steps where you need to write down or remember something.

Computer memory kind of works like that, where the processor will have the memory remember some things while it is working on doing something for you.
Memory is sometimes called RAM, and usually looks like rectangular shaped boards with black things stuck on them, that are then plugged into the motherboard.
The computer talks to the memory through the motherboard and gives it the information to save.
