Question
In a system employing a paging scheme for memory management wasted space is due to _________ .Select one:A.pages of different specified sizesB.internal fragmentationC.frames of different specified sizesD.external fragmentation
Solution
The answer is B. internal fragmentation.
In a paging memory management scheme, the memory is divided into fixed-size blocks known as pages. When a process is to be executed, its pages are loaded into any available memory frames.
Since the page size is fixed, it might happen that the process does not fully occupy the allocated page. The remaining space, which is not used, leads to internal fragmentation.
So, in a paging scheme, wasted space is due to internal fragmentation.

Fragmentation is an unwanted problem in the operating system in which the processes are loaded and unloaded from memory, and free memory space is fragmented. Processes can't be assigned to memory blocks due to their small size, and the memory blocks stay unused.
