Memory management unit (MMU)

A Memory Management Unit (MMU) is a component inside a computer that manages how the system's memory is accessed and used. It translates the addresses used by software into physical locations in the actual memory hardware. This process ensures that applications can use memory efficiently and securely, preventing them from interfering with each other. The MMU also handles memory protection and virtual memory, allowing programs to run as if they have their own dedicated space, even when sharing physical resources. In short, the MMU optimizes and controls access to the computer’s memory resources for smooth and secure operation.
