Explanation:

In virtual memory management, **paging** is the technique where logical memory (a process's address space) is divided into fixed-size blocks called pages. These pages are then mapped to physical memory frames. This allows for non-contiguous memory allocation. * **Option A (Frames):** Frames are fixed-size blocks of *physical* memory, not logical memory. * **Option B (Segments):** Segments are variable-size blocks of logical memory used in segmentation, which is a different memory management technique. * **Option C (Packets):** Packets are units of data used in network communication, unrelated to memory management. * **Option D (Pages):** This is the correct answer. Pages are fixed-size blocks of logical memory, a core concept in paging.
