What are the four major functions of a computer?

The four major functions of a computer encompass the essential operations that enable it to perform tasks effectively. These functions are input, processing, output, and storage.

Input refers to the methods by which data and instructions enter the computer system. This could involve using devices like keyboards, mice, and scanners that allow users to communicate with the computer.

Processing is the function that transforms the input data into useful information. This typically occurs in the central processing unit (CPU), which executes the instructions and performs calculations.

Output involves presenting the results of the processed data to the user or another system. This is done through output devices such as monitors, printers, and speakers, which convey the information in a comprehensible format.

Storage is crucial for saving both the data that is being input and processed, as well as the output results. It encompasses various storage solutions like hard drives, SSDs, and cloud storage that retain information for future access.

Together, these four functions form the foundation of how computers operate and interact with users, making option A the correct choice. Other options may include elements that are part of broader categories or specific aspects of computing, but they do not encapsulate the core functions as clearly and comprehensively as input, process, output, and storage do.
