Which term describes software that coordinates memory allocation to applications and supports virtual memory features?

• A. Memory Manager
• B. Operating System (OS)
• C. Register
• D. Data Bus

Answer: (A)

Memory management coordinates how memory is allocated to running programs and enables virtual memory so each process can address a larger range of memory than physically available. The software that performs this coordination is the memory manager, a component of the operating system. It handles requests to allocate and free memory, tracks which parts of memory are free or in use, and manages the mapping of virtual addresses to physical memory (often using paging and swapping). The operating system includes the memory manager as part of its broader duties, but the term that specifically describes the component handling allocation and virtual memory is memory manager. Registers and the data bus are hardware elements—they store immediate values briefly or move data around—so they don’t describe this software function.
