memory management unit

Short for memory management unit, MMU is the hardware component in your computer that handles virtual memory. Any request for data is sent to the MMU which then determines the location of the information; whether it's in RAM or on a permanent storage drive. The MMU is usually located on your machine's CPU and holds a table for matching physical memory addresses to virtual ones.
