Question
n a system employing a paging scheme for memory management wasted space is due to _________ .Select one:A.frames of different specified sizesB.external fragmentationC.internal fragmentationD.pages of different specified sizes
Solution
The wasted space in a system employing a paging scheme for memory management is due to C. internal fragmentation.
Here's why:
A paging scheme divides memory into fixed-size pages. When a process is to be executed, its pages are loaded into any available memory frames.
Now, let's say a page is smaller than a frame. The remaining space in the frame, which isn't enough to hold another page, is wasted. This is known as internal fragmentation.
So, in the context of a paging system, internal fragmentation can lead to wasted space.
On the other hand, external fragmentation occurs when free memory is divided into small blocks and is scattered throughout the system. This is more associated with systems that use variable partitioning, not paging.
As for options A and D, in a paging system, frames and pages are always of the same size, so there's no question of different specified sizes causing wasted space.

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.
