Which type of computer operates primarily by counting and processing discrete values?

  • Portable Computer
  • Hybrid Computer
  • Analog Computer
  • Digital Computer
Correct Answer: D. Digital Computer

Detailed Explanation

A digital computer operates by processing discrete values, primarily using binary digits, 0 and 1. It performs calculations, comparisons, and logical operations on data represented in digital form. Therefore, Option D (Digital Computer) is the correct answer.


Digital computers process information as separate values rather than continuously changing physical quantities. Modern computers, including desktops, laptops, smartphones, tablets, and servers, are digital computers. They use electronic circuits to represent and manipulate binary data, allowing them to perform a wide range of tasks accurately and efficiently.


An analog computer, in contrast, works with continuous physical quantities such as temperature, pressure, speed, or voltage. A hybrid computer combines features of both analog and digital computers. A portable computer describes a computer designed to be easily carried from one location to another and does not refer to the way it processes data.


Key Points:



  • Digital Computer: Processes discrete data and works using binary values. 

  • Analog Computer: Processes continuous physical quantities.

  • Hybrid Computer: Combines analog and digital processing.

  • Portable Computer: Refers to portability, not the data-processing method.

  • Modern PCs, laptops, smartphones, and servers are digital computers.
