Ok kiddo, so you know how your computer needs to remember things in order to work, right? Well, one of the ways it does that is with something called "memory."
Imagine that memory is like a bunch of little boxes that your computer can put things in and take things out of really quickly. That way, when you open a program or file, your computer can find it in the memory box and use it right away.
Dynamic Random Access Memory, or DRAM for short, is one kind of memory that your computer can use. Basically, DRAM is made up of a bunch of tiny cells that each hold a little bit of information.
But here's the tricky part: these cells don't actually remember things forever. They need to be constantly refreshed with new information, or they will forget what they were holding onto! It's like when you need to keep repeating a phone number to yourself so you don't forget it.
So, DRAM is "dynamic" because it's always changing and being refreshed. But don't worry, your computer knows how to do this all on its own, so you don't need to do anything special.
Overall, DRAM is really important because it helps your computer work quickly and efficiently. So the next time you open a program or do something on your computer, remember that DRAM is helping you do it fast!
