is the most common kind of random access memory (RAM) for personal computers, workstations, printers and almost any kind of data collection equipment.

The readable/writable memory used to store data on the platform. Must be continually refreshed due to its inability to store data longer than a few milliseconds. However, the chips are relatively inexpensive to manufacture and so are worth managing.

is the most commonly used type of volatile memory for the main memory in computing devices.

A type of RAM that requires some external support circuitry. Contrasts with static random access memory. Categorized by speed and memory capacity.

Dynamic random access memory (DRAM) is a type of random access memory that stores each bit of data in a separate capacitor within an integrated circuit. Since real capacitors leak charge, the information eventually fades unless the capacitor charge is refreshed periodically. Because of this refresh requirement, it is a dynamic memory as opposed to SRAM and other static memory.
