Random-access memory, or RAM, is like a super short-term memory that your computer uses to store things while it's working. Think of it like a locker at school - your computer can go in and out of the RAM really quickly to store and retrieve information. It's like a storage space for your computer, but it's only for things that it needs to use very quickly. So when you ask your computer to do something, it can quickly get the information from its RAM.
