Virtual memory uses disk space as an extension of _________

A. Secondary storage
B. Main memory
C. Tertiary storage
D. None of the mentioned

Using swap space significantly _________ system performance.

A. Increases
B. Decreases
C. Maintains
D. Does not affect

Explanation: Disk access is much slower than memory access. Using swap space significantly decreases (or degrades) system performance because it moves data to much slower disk storage (HDD/SSD) when RAM is full, causing delays and potential bottlenecks as the system constantly reads/writes, a process much slower than direct RAM access. While essential for preventing crashes when RAM runs out, excessive swapping leads to a condition called "thrashing," where the system spends more time swapping data than doing useful work.

Linux __________ the use of multiple swap spaces.

A. Allows
B. Does not allow
C. May allow
D. None of the mentioned

Explanation: Putting these swap spaces on separate disks reduces the load places on the I/O system.

A single swap space ______ reside in two places.

A. Can
B. Cannot
C. Must not
D. None of the mentioned

For swap space created in a separate disk partition where no file system or directory structure is placed, _____________ used to allocate and deallocate the blocks.

A. Special routines must be
B. Normal file system routines can be
C. Normal file system routines cannot be
D. Swap space storage manager is

When a fixed amount of swap space is created during disk partitioning, more swap space can be added only by? I) repartitioning of the disk II) adding another swap space elsewhere

A. Only i
B. Only ii
C. Both i and ii
D. Neither i nor ii

In UNIX, two per process ________ are used by the kernel to track swap space use.

A. Process tables
B. Swap maps
C. Memory maps
D. Partition maps
