Question

With paging there is no ________ fragmentation.

a) Internal
b) External
c) Either type of
d) None of these

Answer 1

In paging, there is no external fragmentation because processes are divided into fixed-sized pages that are mapped to physical frames, preventing unused space between allocated units.

Step-by-step explanation:

With paging, there is no external fragmentation. Paging is a memory management scheme that eliminates the need for contiguous allocation of physical memory. This means that processes are divided into pages of a fixed size which are then mapped to physical frames in memory. Since only pages of fixed size are being allocated, there can't be unused space between allocated units, which effectively removes the possibility of external fragmentation. However, internal fragmentation might still occur, as the last page of a process might not be completely filled by the process's memory requirements, leaving some unused space within a page.
