General Computer Architecture

Architecture.

• CPU – accesses main memory to obtain its instructions and then executes them.

• RAM – volatile memory that is much slower than CPU.

• Cache – faster than RAM, but still slower than CPU.

• MMU – Memory Management Unit to help find where the data is stored (RAM or Cache).

• TLB – Translation Lookaside Buffer is a special cache for MMU to translate memory addresses.
