What is Dynamic random access memory (DRAM)?

Dynamic random access memory (DRAM) is like a super-fast notebook that helps your computer remember things while it’s working.

Imagine you have a toy box full of numbered drawers. Each drawer can hold one tiny note, either a 0 or a 1, which are the two basic numbers computers use to think. DRAM works kind of like this toy box, but it's inside your computer and way faster.

DRAM uses something called capacitors, they’re like little batteries that can hold an electric charge. When a capacitor is charged, it represents a 1, and when it’s not charged, it represents a 0. These capacitors are grouped into rows and columns, just like the drawers in your toy box.

But here's the catch: DRAM needs to be "refreshed" regularly because the capacitors slowly lose their charge over time. It's like if you forgot to water your plants, they'll start to wilt! So, your computer constantly checks and recharges these tiny batteries so your notes don’t get lost. That’s why it's called dynamic, it needs constant attention to keep working well.
