• Cache Memory — the buffer between CPU and RAM.

  • Stores frequently used data for quick CPU access
  • Faster but smaller than RAM
  • Falls between the CPU and main memory
  • Has levels (L1, L2, L3) — L1 is fastest/closest to CPU
  • Reduces memory access time, boosting performance

Additional information:

• RAM = the main memory itself
• ROM = read-only, holds firmware (BIOS)
• SRAM = a type used to build cache, not the buffer itself
