Computer Fundamentals and System Concepts Questions

Multiple choice

RISC architecture became popular after the invention of _____________________.

  1. VLSI technology

  2. Micro programme technology

  3. Pipelining technology

  4. MSI technology

  5. None of the above

Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Micro programs allowed more than one action in a single OPCODE, thereby reducing the circuits required compared to CSIC. This helped in execution of more complex instructions in reduced circuits. So, ASIC became popular.

Multiple choice

For networking, one requires a ____ CPU in the system.

  1. specially architect

  2. normal architect

  3. micro-controllers type architect

  4. complex architect

  5. none of the above
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Networking is mainly provided by the LAN-card, OS and other software. So, a general purpose processor can handle the networking.

Multiple choice

Human body is an ideal example of

  1. multitasking

  2. multiprogramming

  3. distributed processing

  4. pipelining

  5. none of the above
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

When hands are working, eyes may look somewhere and provide visuals while feet are doing the walking. All the above operations are performed simultaneously without affecting each other and without pausing. This type of working is distributed processing. 

Multiple choice

Loader is used by operating system at _____ of a program.

  1. compile time

  2. code optimization time

  3. execution time

  4. text editing time

  5. none of the above
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Loader uses the compiled and linked program to move it from secondary storage to main memory for its execution by CPU. Hence, it must be required when the program is ready for execution. Option 3 is correct.

Multiple choice

I/O controllers are

  1. intelligent but dedicated processors

  2. to control CPU for I/O

  3. super computers

  4. dumb devices

  5. none of the above
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

I/O controllers have separate processors and dedicated instruction formats to define various dedicated operations for the specific device. They offload CPU during I/O operations.

Multiple choice

MODEM is ____________.

  1. Modular Editing Machine

  2. Modern Engineering Machine

  3. Model of Microprocessor

  4. Modulator and Demodulator

  5. None of these
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

It handles the conversion of the digital incoming and outgoing packets.

Multiple choice

FORTRAN is a/an ________.

  1. operating system

  2. high level language

  3. search engine

  4. communication protocol

  5. system software
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

FORTRAN stands for formula translator, FORTRAN is the oldest high-level programming language designed by John Backus for IBM in the late 1950s, it is still popular today, particularly for scientific applications that require extensive mathematical computations.

Multiple choice

Transistors were first time used in __________ computers.

  1. 1st generation

  2. 2nd generation

  3. 3rd generation

  4. 4th generation

  5. 5th generation
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Transistors were first time used in Second Generation computers. The period of second generation was 1959-1965. This generation using the transistor were cheaper, consumed less power, more compact in size, more reliable and faster than the first generation machines made of vacuum tubes. In this generation, magnetic cores were used as primary memory and magnetic tape and magnetic disks as secondary storage devices. In this generation, assembly language and high-level programming language like FORTRAN, COBOL were used. There were Batch processing and Multiprogramming Operating system used.

Multiple choice

Which of the following is incorrect about first generation computers?

  1. Vaccume tubes were used.

  2. It had drum primary storage.

  3. It required continous maintenance.

  4. Real time processing was possible.

  5. It did batch processing.
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

The statement is incorrect about first generation computers. Real time processing was not possible in first generation computers. It was possible in third generation computers.

Multiple choice

A computer cannot “boot” if it does not have the

  1. Compiler

  2. Loader

  3. Operating system

  4. Assembler

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

The operating system (OS) is essential software that manages computer hardware and software resources. Without an OS, the computer cannot perform the boot sequence which loads system files, initializes hardware, and prepares the system for use. Compilers, loaders, and assemblers are development tools that run after the OS is running.

Multiple choice

_____means the altering of computer system software to achieve a task for which it was not originally designed.

  1. Pegging

  2. Hacking

  3. Trekking

  4. Breaking

  5. All of these
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Hacking refers to the practice of modifying computer system software or hardware to accomplish a goal outside the creator's original purpose. While often associated with unauthorized access, the term broadly covers any alteration to achieve unintended functions. Pegging, trekking, and breaking are not related to computer system modification.
