What is DRAM？

DRAM (Dynamic Random Access Memory) is volatile memory that stores data in capacitors, requiring constant refreshing to maintain information. It's widely used as a computer's main memory due to its cost-effectiveness and speed.

Simply Put:

Imagine using sticky notes to remember things, but they often fall off or get lost. So you have to keep rewriting new ones to keep the info. That’s what DRAM does, it stores data temporarily but needs constant refreshing to keep it from disappearing.
