Computer Fundamentals and System Concepts Questions

Multiple choice

The _______ instructs the various parts of the computer to perform the necessary tasks to keep the computer operating smoothly and efficiently.

  1. arithmetic/logic unit

  2. primary memory

  3. control unit

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

The control unit is the component that directs all computer operations. It coordinates the activities of the arithmetic/logic unit, memory, and input/output devices by issuing control signals. The ALU performs calculations (like option D), primary memory stores data, and secondary storage provides permanent storage, but only the control unit manages the entire system.

Multiple choice

Which of the following is a logical operation that a computer is capable of performing?

  1. Transferring the program from a primary storage unit to a diskette

  2. Accepting a collection of data

  3. Determining if the number 10 is less than the number 8

  4. Adding 6 and 15

C Correct answer
Explanation

Logical operations involve comparisons and decision-making based on conditions. Determining if one number is less than another (10 < 8) is a comparison operation, which is logical. Options A and B are data transfer operations, while D (adding 6 and 15) is an arithmetic operation, not logical.

Multiple choice

Microcomputers are popular because _______.

  1. they create a fair amount of heat and need special cooling

  2. they are the fastest type of computer currently available

  3. they were developed in the 1960s

  4. there is an enormous supply of inexpensive software

B Correct answer
Multiple choice

A(n) _______ system is a special collection of programs that help the computer work efficiently.

  1. floppy disk

  2. monitoring

  3. menu

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

An operating system (OS) is the fundamental software that manages computer hardware and software resources. It provides services for computer programs and acts as an intermediary between users and hardware. Floppy disk is storage, monitoring is a process, and menu is an interface element - none are system software.

Multiple choice

The primary processes carried out by a computer are ______.

  1. input/process/output

  2. input/output

  3. input/storage/output

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

The fundamental computing process involves three stages: input (receiving data), process (manipulating data using CPU), and output (producing results). Storage is important but is not part of the primary process flow. Option A captures all three essential stages.

Multiple choice

Which of the following assemblers is an open set of technical specifications that any person or company can license and use to develop microprocessors and other semiconductor devices based on published industry standard?

  1. MASM

  2. MASM32

  3. SPARC Assembler

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

This assembler is an open set of technical specifications that any person or company can license and use to develop microprocessors and other semiconductor devices based on published industry standard.
