Memory: RAM, ROM and Cache Memory Functions
RAM (Random Access Memory)
A volatile memory that stores data for short-term use.
Data is lost when the computer is powered off.
Examples: hard drive, hard disk drive, RAM stick.
ROM (Read-Only Memory)
A non-volatile memory that stores data permanently.
Data is preserved even when the computer is powered off.
Examples: hard drive, chip card, flash drive.
Cache Memory
A shared memory between the CPU and other memory types.
Cached data is frequently accessed by the CPU.
Examples: L1 cache, L2 cache, L3 cache.
Key Differences
RAM is closest to the CPU, while ROM is farthest away.
RAM is volatile, while ROM is non-volatile.
Cache memory is shared between the CPU and other memory types.
How They Are Used Together
RAM holds the data that is currently being processed by the CPU.
ROM contains data that needs to be preserved even when the system is powered off.
The cache memory is used as a temporary storage area for frequently accessed data
