Computer Memory and Storage Questions
A
Correct answer
Explanation
Virtual memory uses a portion of secondary storage (like a hard drive or SSD) to act as an extension of physical RAM. This allows the system to run larger applications or more processes than physical memory alone would permit.
-
Ensures each process has enough memory to perform job
-
Ensures each process is followed step by step
-
Ensures each process is prioritized in importance
-
It doesnt care
A
Correct answer
Explanation
Memory management is a core OS function that allocates memory to processes as needed. It ensures that each process has sufficient space to execute and prevents processes from interfering with each other's memory space.
A
Correct answer
Explanation
During the boot process, the OS kernel initializes and loads essential device drivers into memory. This allows the OS to communicate with hardware components immediately upon startup.
A
Correct answer
Explanation
The file system, which is a component of the operating system, is responsible for organizing and tracking where data is stored on physical storage media like hard disks.
-
control the hardware
-
manage all software
-
store information
-
organize information
C
Correct answer
Explanation
In computing, drives (like hard drives, USB drives, or optical drives) are the physical or logical storage media used to store information and data.
A
Correct answer
Explanation
Virtual memory uses a portion of the hard drive to act as an extension of physical RAM when the system runs low on memory, allowing for more programs to run simultaneously.
-
Power off
-
Restart from ON state
-

-
Performance Monitor
-
Disk Cleanup
-
Task Manager
-
Defragmenter
D
Correct answer
Explanation
Disk Defragmenter rearranges fragmented data on hard drives, consolidating scattered file segments to improve read/write performance. As files are created, modified, and deleted, data becomes scattered across the disk, slowing access times. Defragmentation physically reorganizes this data for optimal performance. (Note: 'seperated' in the question is misspelled).
B
Correct answer

-
That part of the brain that is hard to find.
-
Everything you type on the keyboard.
-
The way you unlock a computer.
A
Correct answer
