Question: Which of the following is NOT one of the four major data processing functions of a computer?

Answer:

The four major data processing functions of a computer are:

1. Input: This involves gathering or capturing data and instructions from external sources and bringing them into the computer system. Input devices such as keyboards, mice, scanners, sensors, and microphones are used to input data into the computer.

2. Processing: Once the data is inputted, the computer processes the data by performing calculations, manipulating the data, and executing instructions. This processing is carried out by the Central Processing Unit (CPU) of the computer.

3. Output: After processing, the computer produces output by presenting the results or information in a human-readable or machine-readable format. Output devices such as monitors, printers, speakers, and storage media are used to display, print, or store the output.

4. Storage: Data and instructions that are not being actively processed or used are stored in various types of storage media, such as hard disk drives, solid-state drives, optical disks, or cloud storage. This allows for the persistent storage and retrieval of data for future use.

These four functions—input, processing, output, and storage—are collectively known as the data processing cycle and form the core operations of a computer system.

MCQ: Which of the following is NOT one of the four major data processing functions of a computer?

A. gathering data
B. processing data into information
C. analyzing the data or information
D. storing the data or information
E. None of the above

Correct Answer: A. gathering data
