Question
Which memory management technique uses fixed-size blocks of memory, allowing for efficient memory allocation and de-allocation? A. Swapping B. Paging C. Swapping D. Segmentation
Solution
The memory management technique that uses fixed-size blocks of memory, allowing for efficient memory allocation and de-allocation is B. Paging.
Here's why:
A. Swapping: This is a method where a process can be swapped temporarily out of memory to a backing store, and then brought back into memory for continued execution. It doesn't necessarily use fixed-size blocks of memory.
B. Paging: This technique divides computer's primary memory into fixed-size units called page frames, and program's logical memory into blocks of the same size called pages. When a program needs to access a page that is not in primary memory, the system swaps it with one that is. This is the correct answer.
C. Swapping: This is the same as option A, and thus, incorrect.
D. Segmentation: This is a method that divides a program into segments which may not be all of the same sizes. This doesn't use fixed-size blocks of memory.

In modern operating systems, how does virtual memory management enhance system stability and efficiency, and what techniques are used to manage virtual memory effectively?(a) Virtual memory management combines multiple physical memory modules into a single logical unit, increasing available memory and simplifying memory allocation.(b) Virtual memory management allows processes to use disk space as an extension of RAM, ensuring that memory-hungry applications do not crash the system. Techniques include demand paging and swap space management.(c) Virtual memory management enhances system stability and efficiency by using paging and segmentation to isolate processes and by implementing page replacement algorithms to optimize memory usage. This approach allows processes to run as if they have access to a large contiguous block of memory, even when physical memory is limited.(d) Virtual memory management allocates fixed memory segments to different processes, reducing the likelihood of memory leaks and improving overall system performance.(e) Virtual memory management relies solely on increasing physical RAM to handle larger workloads, which improves stability but does not optimize efficiency.
