Final answer:
The correct answer is a) the entire process, pages - A swapper manipulates the entire process, while the pager manages individual pages of a process in memory management schemes.
Step-by-step explanation:
A swapper manipulates the entire process, whereas the pager is concerned with individual pages of a process. The correct answer to the question is: a) the entire process, pages.
In operating systems, swapping refers to moving entire processes in and out of the main memory, whereas paging is a memory management scheme that allows the physical address space of a process to be noncontiguous.
This facilitates efficient memory usage by enabling a process to be divided into pages and those pages to be stored across various sections of the memory or a disk.
