Multiple choice

Recycle bin ___________.

  1. is a folder that contains deleted files and folders

  2. is a folder that contains the files used for backup

  3. is a file that contains the file information on the disk

Multiple choice

When a program is executed on a distributed system, the user is not aware of where the program is executed or the location of the resource accessed. Which operating system is used for this?

  1. Network operating system

  2. Time sharing operating system

  3. Multiprocessor operating system

  4. Distributed operating system
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Distributed operating systems provide transparency - users don't need to know where their programs execute or where resources are located. The OS manages this abstraction across multiple machines seamlessly.

Multiple choice

The purpose of a ____ is to request the operating system to perform same task. A/An _____ provides an interface between a process and the operating system.

  1. system call, supervisor call

  2. supervisor call, interrupt

  3. system call, system call

  4. None of these
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

A system call is the mechanism by which a program requests a service from the OS kernel. It also provides the interface boundary between user processes and the operating system. Both blanks refer to this same concept.

Multiple choice

Which word is related to processing the speed in computers?

  1. EFTS

  2. MPG

  3. NIPS

  4. CPS
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

CPS stands for Cycles Per Second, an older unit for measuring processing speed in computers (now largely replaced by Hertz or Hz). EFTS refers to electronic funds transfer, MPG is miles per gallon (fuel efficiency), and NIPS was a neural information processing conference (now NeurIPS).

Multiple choice

A computer virus is _____.

  1. a chemical that attacks silicon

  2. a micro - organism that destroys integrated circuits

  3. data that the computer fails to handle

  4. a special kind of computer programme
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

A computer virus is a type of malicious software (malware) that replicates itself by inserting copies into other programs or documents. It is not a chemical or biological organism - those first two options are common misconceptions playing on the word 'virus'. Option C is incorrect because viruses are specifically designed code, not random data the computer can't handle.
