Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
when the memory manager uses ____, it allocates fixed sized blocks of memory to processes
A
paging
B
segmentation
C
virtual memory
D
polling
Explanation: 

Detailed explanation-1: -Paging is the memory management technique in which secondary memory is divided into fixed-size blocks called pages, and main memory is divided into fixed-size blocks called frames. The Frame has the same size as that of a Page.

Detailed explanation-2: -With Paging, Physical memory is broken into fixed-sized blocks called frames. Logical memory is also broken into blocks of the same size called pages. When a process is to be executed, its pages are loaded into any available memory frames from the backing store.

Detailed explanation-3: -In the Paging method, the main memory is divided into small fixed-size blocks of physical memory, which is called frames.

Detailed explanation-4: -Paging is a function of memory management where a computer will store and retrieve data from a device’s secondary storage to the primary storage. Memory management is a crucial aspect of any computing device, and paging specifically is important to the implementation of virtual memory.

Detailed explanation-5: -Worst fit: The memory manager places a process in the largest block of unallocated memory available. The idea is that this placement will create the largest hold after the allocations, thus increasing the possibility that, compared to best fit, another process can use the remaining space.
