Computer Fundamentals and System Concepts Questions

Multiple choice

Transistorized computer circuits were introduced in the

  1. first generation

  2. second generation

  3. third generation

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

The second generation of computers (roughly 1955-1965) replaced vacuum tubes with transistors, which were smaller, faster, and more reliable.

Multiple choice

The difference engine was to be

  1. an electronic digital computer

  2. an electromechanical device

  3. powered by steam

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

Charles Babbage's Difference Engine was a mechanical calculator designed to be powered by steam, intended to automate the calculation of mathematical tables.

Multiple choice

An Example of an early stored program computer was

  1. EDVAC

  2. ENIAC

  3. both (1) and (2)

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

The EDVAC (Electronic Discrete Variable Automatic Computer) was one of the earliest computers to implement the stored-program concept, following the theoretical design of Von Neumann.

Multiple choice

The hub is a

  1. software

  2. hardware

  3. both (1) and (2)

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

A hub is a physical networking device used to connect multiple devices in a network, making it hardware.

Multiple choice

The bridge is a

  1. hardware device

  2. software program

  3. both (1) and (2)

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

A network bridge is a computer networking device that creates a single, aggregate network from multiple communication networks or network segments.

Multiple choice

Prototype is a

  1. mini model of the existing system

  2. mini model of the proposed system

  3. working model of the existing system

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

A prototype is an early, simplified version of a proposed system used to test concepts and gather user feedback before full-scale development.

Multiple choice

Design specifications do not normally include

  1. output requirements

  2. input and storage requirements

  3. control provisions

  4. blueprints showing the layout of hardware
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Design specifications focus on logical and functional requirements like inputs, outputs, and controls. Physical hardware layout is typically part of implementation or physical design, not the core design specification.

Multiple choice

To implement an MIS,

  1. a computer is inescapable

  2. an e-mail is required

  3. proper systems and procedures must be in place

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

An MIS is primarily about information flow and decision support; while computers are common tools, the foundation must be proper organizational systems and procedures.

Multiple choice

The physical design of a new system must consider all of the following except

  1. input, output, processor

  2. management objectives

  3. control and backup

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

Physical design focuses on the technical implementation of the system, including hardware, software, and data structures. Conversion methods are part of the implementation phase, which occurs after the design is finalized.

Multiple choice

System specification is mainly concerned with

  1. how the functions are performed

  2. what functions are to be performed

  3. both (1) and (2)

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

System specification defines both the requirements (what the system must do) and the design constraints (how the system will achieve those requirements). Therefore, it encompasses both aspects.
