Sample questions with answers and explanations

Sample 1

Which of these is NOT an input device?

Answer: A

An input device sends data INTO the computer. A screen does the opposite — it shows results coming OUT — so it is an output device, not an input one.

Why the other choices are wrong
  • B. A scanner sends pictures of documents into the computer, so it is an input device.
  • C. A microphone feeds sound into the computer, so it is an input device.
  • D. A keyboard sends your typing into the computer, so it is an input device.

Sample 2

Which software allows end users to accomplish one or more specific tasks not directly related to computer development?

Answer: A

Application software is built to help the user do a specific job, like writing a letter or making slides — tasks that have nothing to do with running the computer itself.

Why the other choices are wrong
  • B. Utilities are helper tools that clean up or maintain the computer, not the user's everyday tasks.
  • C. An operating system runs the computer; it does not do the user's specific tasks.
  • D. System software supports the computer's own running, not the user's specific tasks.

Sample 3

_____ is a vast network of computers located all over the world and linked to one another.

Answer: B

The Internet is the giant worldwide network that joins millions of computers so they can share information with each other.

Why the other choices are wrong
  • A. 'Digital' just means something uses numbers/electronic signals; it is not a network of computers.
  • C. Facebook is one website you visit on the Internet, not the whole network itself.
  • D. A search engine is a tool for finding pages on the Internet, not the network of computers.
