Which one of the following is a technique of dividing the physical memory space into multiple blocks ?

Paging is a memory management scheme that eliminates the need for contiguous allocation of physical memory. In this technique, the physical memory is divided into fixed-size blocks called frames, while the logical memory (the process's address space) is divided into blocks of the same size called pages.

• Segmentation is a memory management scheme that divides the logical address space into variable-sized blocks called segments based on the user's view (e.g., functions, objects).
• Fragmentation is not a technique but a condition where memory is wasted either within allocated blocks (internal) or between them (external).
• Swapping is a mechanism where a process is temporarily moved from the main memory (RAM) to secondary storage (disk) to free up memory for other processes.
