Computer Fundamentals and System Concepts Questions

Multiple choice

LSI means

  1. large scale integration

  2. long scale integration

  3. long small integration

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

LSI stands for Large Scale Integration, which follows MSI in the hierarchy of integrated circuit complexity.

Multiple choice

VLSI means

  1. very large scale integration

  2. very long scale integration

  3. very large short integration

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

VLSI stands for Very Large Scale Integration. This refers to the process of creating an integrated circuit by combining millions of MOS transistors onto a single chip.

Multiple choice

A bug is a ______ in the design of a software.

  1. mistake

  2. key board

  3. mouse

  4. ram
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

In software engineering, a bug is an error, flaw, failure, or fault in a computer program or system that causes it to produce an incorrect or unexpected result.

Multiple choice

What is Booting?

  1. Initialization of programs

  2. Starting the system

  3. Starting and loading of OS programs for execution

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

Booting is the process of starting a computer. It involves loading the operating system into the computer's main memory so that it can execute programs.

Multiple choice

_________ transisters are there in Pentium processor.

  1. 1

  2. 100

  3. Several million

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

Pentium processors contain millions of transistors, ranging from about 3 million in early versions to much more in later versions. 'Several million' is the most accurate description. One or one hundred transistors is far too few for a CPU.

Multiple choice

Hardware that adds _________ numbers is ALU.

  1. 2

  2. 4

  3. 5

  4. 6
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The Arithmetic Logic Unit (ALU) is the component of a CPU that performs arithmetic operations like addition. While ALUs can add any numbers, binary addition (adding 2 numbers) is fundamental to how computers process information. The other options (4, 5, 6) are not standard ways to describe ALU functionality.

Multiple choice

_______ does not generate a hardware interrupt.

  1. Program error

  2. Hard Disc

  3. Both (1) and (2)

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

A hardware interrupt is triggered by external hardware devices (like a hard disk or keyboard). A program error (like division by zero) triggers a software interrupt or exception, not a hardware interrupt.
