What Is Memory?

Where is it all stored?

So far in this course, we have learned about how the binary system is used to represent numbers, ranging from integers and signed numbers, to very large and small numbers. In the previous lesson, we have also seen how letters and symbols are encoded to numbers, so that they can be represented in binary, too.

However, there is still the question of where exactly these numbers are stored in our physical computers.

You have probably heard about computer storage and computer memory. You must vaguely know that these have something to do with the CPU. Let’s see what storage and memory actually are, and what purpose they each fulfill.
