The correct option is E Pages
In virtual storage, program segments stored on disk
during processing are called Pages.
Virtual storage is the pooling of physical storage
from multiple network storage devices into what appears to be a single storage
device that is managed from a central console.
The virtual memory is divided into pages (4
kilobytes is typical). Backing each page of virtual memory is a page of real
memory (called a frame) or some secondary storage, usually disk space. The disk
space might be swap space or just some ordinary disk file. Actually, a page of
all zeroes sometimes has nothing at all backing it – there’s just a flag saying
it is all zeroes.
The same frame of real memory or backing store can
back multiple virtual pages belonging to multiple processes. This is normally
the case, for example, with virtual memory occupied by GNU C Library code. The
same real memory frame containing the printf function backs a virtual memory
page in each of the existing processes that has a printf call in its program.
