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 determines the location of the information, whether it's RAM (random-access memory) or a permanent storage drive. The MMU is usually on your machine's CPU (central processing unit) and holds a table for matching physical memory addresses to virtual ones.
