Computers need memory to remember things while they are working. Imagine you're in a classroom, and your teacher gives you problems one by one. You can only solve each problem if you keep track of the numbers in your head, that’s like memory. If the class gets too big, it becomes hard to remember everything at once, so computers use extra memory, like having more notebooks on your desk.
Examples
- A child uses one notebook to solve math problems. If they get more problems at once, they need more notebooks.
- If a computer only has one notebook, it gets confused when many programs are open.
