Computer Fundamentals and System Concepts Questions

Multiple choice

Multiprogramming was made possible by

  1. input / output units that operate independently of the CPU

  2. operating system

  3. both (1) and (2)

  4. neither (1) nor (2)
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Multiprogramming requires both hardware capability (independent I/O units that don't block the CPU) AND software (the operating system to manage multiple processes). The OS switches the CPU between processes when one does I/O, while independent I/O units allow the CPU to continue executing other processes instead of waiting.

Multiple choice

Operating system is

  1. a collection of hardware components

  2. a collection of i/o devices

  3. a collection of software routine

  4. all the above
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

An operating system is a collection of software routines that manage hardware resources and provide services for applications. It is NOT hardware components (that's the machine itself) or I/O devices (physical peripherals), though it controls both.

Multiple choice

The term 'operating system' means

  1. a set of programs which controls a computer's working

  2. the way a computer operates and works

  3. conversion of high level language into machine code

  4. the way a floppy disk drive operates

A Correct answer
Explanation

The term 'operating system' means a set of programs which controls a computer's working.

Multiple choice

PARAM 10000 is a

  1. Micro computer

  2. Mainframe computer

  3. MINI computer

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

Super computer

Multiple choice

Where would you find the use of Reverse Engineering?

  1. Printers

  2. Storage devices

  3. Operating system

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

The term reverse engineering has it origins in the hardware world. A company disassembles a competitive hardware product in an effort to understand its competitor's design and manufacturing secrets.

Multiple choice

The first indegenously built Indian super computer is called

  1. ANURAG

  2. ISC-I

  3. PARAM

  4. BHARAT
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

PARAM (Parallel Machine) was the first indigenously built Indian supercomputer, developed by the Centre for Development of Advanced Computing (C-DAC) in 1991. It marked India's entry into high-performance computing and was developed as part of India's technology self-reliance initiative after US technology denial in the 1980s.

Multiple choice

'Computer Virus' is a

  1. biological virus

  2. destructive program

  3. constructive program

  4. interruptive program
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

'Computer Virus' is a destructive program.

Multiple choice

Micro computer should be made because of invention of ______.

  1. Intergrated Circuit

  2. Transistor

  3. Protocols

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

Microcomputers became possible due to the invention of integrated circuits (ICs), which miniaturized electronic components onto tiny silicon chips. ICs replaced bulky transistors and vacuum tubes, making small, affordable personal computers possible. Without IC technology, computers would have remained large, expensive mainframes.

Multiple choice

A computer is a _____ device.

  1. calculating

  2. electrical

  3. electronic

  4. all of these
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

A computer is fundamentally an electronic device that processes data using electronic components like integrated circuits, transistors, and circuits. While computers can perform calculations, 'calculating device' is too narrow - they do much more. They're not merely 'electrical' devices (which use electricity but aren't digital), they're specifically electronic devices using electronic components for data processing.
