Question 10

All of the following are TRUE regarding virtual memory EXCEPT
A)any amount of ram can be allocated to virtual memory
B)the setting for the amount of hard disk drive space to allocate virtual memory canbe manually change
C)this temporary storage is called the swap file or page file
D)virtual memory is the physical space o the hard drive

Accepted Answer

Virtual memory cannot have any arbitrary amount of RAM allocated to it; it is limited by the system's hardware and operating system constraints.

Question 11

B)linux is a proprietary whereas windows is not
C)there are multiple versions of linux, but only one version of windows
D)any programmer can modify linux code which is not permitted with windows

Accepted Answer

Linux is open-source, meaning its source code is freely available for anyone to view, modify, and distribute. Windows, on the other hand, is proprietary software owned by Microsoft, and its source code is not available for public modification or distribution.

Question 12

What is dispatch latency?
A)the timetaken by the dispatcher to stop one process and start another
B)the timetaken by the processor to write a file into disk
C)the whole timetaken by all processor
D)none ofabove

Accepted Answer

Dispatch latency refers to the time taken by the dispatcher to stop one process and start another, including the time for context switching, scheduling, and any other overheads involved in the process switch.

Question 13

A page fault occurs when
A)the deadlock happens
B)the segmentation starts
C)the page is found in the memory

Question 15

Which of the following does not occur during the power-on-self-test (POST)?
A)the scandisk utility begins to run
B)the video card and video memory are tested
C)the bios identification process occurs
D)memory chipare checked to ensure that they are working properly

Accepted Answer

The scandisk utility does not begin to run during the power-on-self-test (POST). POST is a process performed by the firmware or software routines immediately after a computer or other digital electronic device is powered on. This process checks the hardware components like video card, BIOS, and memory chips to ensure they are working properly. Scandisk, however, is a utility that checks and repairs file systems and bad disk sectors, which is run from within the operating system rather than at the hardware level during POST.

Question 16

The maximum size of a write file is limited to only
A)name of the file
B)extension of the file
C)the amount of memory in your computer
