Paging is a memory management technique that divides the physical memory (RAM) into fixed-size units called frames and the logical address space of a process into equally sized units called pages. It is a method of dividing physical memory into blocks (frames) to facilitate non-contiguous memory allocation and virtual memory implementation.

Paging divides physical memory into fixed-size frames and logical memory into same-size pages, enabling processes to be loaded into non-contiguous physical memory locations.

Fragmentation refers to wasted space in memory. Segmentation divides logical memory into variable-size segments based on the program’s structure. Swapping is a technique to move processes between memory and disk to manage limited physical memory resources, not a method of dividing physical memory into blocks for allocation.
