Learn: RAM

Welcome!Today we'll learn about RAM (Random Access Memory). RAM is an essential part of a computer's memory system, and understanding it will help you see how computers work!

What is RAM?RAM is a type of primary storage used by the computer to temporarily store data and instructions while they are being processed. It is volatile, which means it loses its contents when the computer is turned off.

Why is RAM important?RAM allows the computer to quickly access data it needs while running programs. It is much faster than secondary storage like a hard drive. Without enough RAM, a computer may run slowly or struggle to perform tasks efficiently.

Features of RAMRAM is designed to be fast for quick access and processing. It works closely with the CPU to store instructions and data currently being used. The more RAM a computer has, the more tasks it can handle simultaneously.

RAM vs ROMWhile RAM is used for temporary storage, ROM (Read-Only Memory) is used for permanent storage of instructions, such as those needed to start up the computer. ROM retains its data even when the computer is turned off.

Virtual MemoryIf the RAM runs out of space, the computer can use virtual memory by temporarily storing data on the hard drive. While slower than RAM, it helps the computer continue running tasks.
