Computer Fundamentals and System Concepts Questions

Multiple choice

Programs stored in ROM are called

  1. malware

  2. firmware

  3. spyware

  4. all of these
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Firmware is software that is stored permanently in ROM (Read-Only Memory) chips. Unlike regular software that can be easily modified, firmware provides the basic instructions for device operation and remains constant. Malware and spyware are malicious programs that would not be permanently stored in ROM by design. 'All of these' is incorrect because only firmware is the correct term for ROM-stored programs.

Multiple choice

Which of the following digital devices processes the data?

  1. Data processor

  2. Data entry

  3. DBMS

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

A data processor is any digital device that processes or manipulates data according to instructions. This is the fundamental definition of computing devices. Data entry is the act of inputting data, not processing it. DBMS (Database Management System) is software for organizing databases, not the processing device itself. Database is stored information, not a processing device. Only 'Data processor' correctly describes a device that processes data.

Multiple choice

Which of the following is not a component of CPU?

  1. Control Unit

  2. Arithmetic Logic Unit

  3. Output Unit

  4. Memory Unit

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

The CPU (Central Processing Unit) consists of three main components: Control Unit (CU), Arithmetic Logic Unit (ALU), and Memory Unit (registers/cache). The Control Unit directs operations, the ALU performs mathematical and logical operations, and the Memory Unit stores data temporarily during processing. The Output Unit is NOT part of the CPU - it is a separate component of the computer system that handles display or transmission of processed results to peripherals like monitors or printers.

Multiple choice

Which of the following correctly describes a motherboard?

  1. It is a type of CPU chip.

  2. It is a circuit board that has peripheral devices.

  3. It is the first chip to be accessed when a computer is started.

  4. It is a circuit board containing CPU and other chips.

Multiple choice

The first general purpose of digital computer was called

  1. ENIAC

  2. UNIVAC-1

  3. MARK-1

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

The first ever general purpose digital electronic computer was dedicated at the University of Pennsylvania. The machine was called the ENIAC (Electronic Numerical Integrator and Computer).

Multiple choice
