Computer Fundamentals and System Concepts Questions

Multiple choice

Benefit(s) of computers is/are that

  1. they are machines

  2. they are accurate

  3. they are intelligent

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

Among the options, accuracy is a key benefit of computers. While computers are indeed machines (option A), this is a description rather than a benefit. Option C (intelligent) is incorrect because computers follow programmed instructions without true intelligence. Option D is false because accuracy is a genuine advantage of computers over manual calculation.

Multiple choice

Third generation of computers have

  1. high-level procedural languages for the first time

  2. an operating system for first time

  3. on-line real time system

  4. distributed data processing
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Third-generation computers (1960s, integrated circuits) saw the widespread adoption of high-level procedural languages like FORTRAN, COBOL, and ALGOL. Operating systems and real-time systems existed in second generation, while distributed computing emerged later.

Multiple choice

Which of the following are mandatory parts of a complete PC system?

  1. Keyboard and printer

  2. Input and output

  3. Hardware and software

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

A complete PC system requires both hardware (physical components like CPU, memory, storage) and software (operating system and applications) to function. Input and output devices are hardware components, but not sufficient alone. A keyboard and printer are not mandatory.

Multiple choice

Library management software is for

  1. documenting the changes that are made to programs

  2. controlling the version numbers of the programs

  3. both (1) and (2)

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

Library management software is used for version control - it tracks program changes (documentation) and manages version numbers. This is essential for maintaining software integrity and allowing rollback to previous versions if needed.

Multiple choice

Which of the following is not a characteristic of a computer?

  1. Speed

  2. Intelligence

  3. Automation

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

Computers are characterized by speed, automation, and versatility - they can perform tasks quickly, operate automatically, and handle diverse applications. Intelligence is not a characteristic - computers follow programmed instructions without cognitive understanding.

Multiple choice

Which of the following is/are not a part of system?

  1. Electric supply

  2. Peripherals

  3. Common goal

  4. Logical interconnection between peripherals
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

A system comprises physical components (peripherals, electric supply) and their connections. A common goal is a purpose or objective, not a component part. The goal exists outside the system's physical structure.

Multiple choice

Which of the following is/are true?

  1. A Pc/XT uses an 80186 microprocessor whereas a PC/XT uses an 80286 microprocessor.

  2. If the power goes off while executing a program, the instructions and data in the memory will be lost.

  3. Both (1) and (2)

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

RAM is volatile memory - when power is lost, all stored data and instructions are erased. This is why unsaved work is lost during power outages. PC/XT systems used 8088 processors, not 80186 or 80286 as mentioned in option A.

Multiple choice

Which of the following components of .Net architecture provides the appearance of a virtual machine so that programmers need not consider the capabilities of the specific CPU that will execute the program?

  1. Common type system

  2. The execution support

  3. Stack walk

  4. Web form

  5. Common language runtime
Reveal answer Fill a bubble to check yourself
E Correct answer
Explanation

This component of .Net architecture provides the appearance of an application virtual machine so that programmers need not consider the capabilities of the specific CPU that will execute the program.
