*Volatile
*Temporarily stores data & instructions for CPU
Cache Memory
*Small unit of ultrafast memory built into or near the processor
*Stores frequently or recently access info
*3 Lvls. = L1 (primary), L2 (secondary), L3
ROM (Read-only Memory)
*Nonvolatile
*BIOS - 1st code when compy is powered on
*CMOS - Starts the power-on self-test
POST - checks circuitry & RAM
Bootstrap Loader - locates & loads OS into RAM |
