Memory Management Unit
A Memory Management Unit (MMU) is a hardware component that manages the mapping between virtual addresses used by a program and physical addresses in computer memory. The MMU translates virtual addresses to physical addresses, allowing programs to access memory without knowing the physical location of the data. The MMU also provides memory protection by ensuring that programs cannot access memory that they are not authorized to access. The MMU is an essential component of modern operating systems, which use virtual memory to allow programs to access more memory than is physically available. The MMU is responsible for managing the mapping between virtual and physical memory, ensuring that programs can access the memory they need while protecting the system from unauthorized access.
