List-I (Term) A. Page Frame B. Page C. MMU D. TLB List-II (Functional Definition) Hardware unit that translates logical addresses to physical ones. A fixed-size block of physical main memory storage. Fast-access hardware cache storing recent page translations. A fixed-size block of logical user-space memory.

A-2, B-4, C-1, D-3 Explanation: A. Page Frame 2 : Physical main memory (RAM) is divided into equal, fixed-size contiguous blocks called page frames. B. Page 4 : Logical address space (user program memory) is divided into fixed-size blocks of the same size as physical page frames, known as pages. C. MMU (Memory Management Unit) 1 : The hardware component on the CPU responsible for mapping and translating logical (virtual) addresses to physical memory addresses at runtime. D. TLB (Translation Lookaside Buffer) 3 : A high-speed hardware cache located within the MMU that stores recent virtual-to-physical address mappings to speed up memory access. Therefore, the correct mapping is A-2, B-4, C-1, D-3 .
