Space partitioning

Space partitioning is a way of organizing data in a computer. It basically means breaking up a large area of memory into smaller parts, so that each part can be used for a different purpose. For example, if you had a computer with a lot of memory, but you wanted to store lots of different things, you could break it up into smaller sections, like a big cake that you divide into slices. Each slice can then be used to store different things. This makes it easier to find and use the data that you need.
