An electronic tool that allows information to be input, processed, and output
A CPU
B Operating System
C Computers
D Motherboard
The correct answer and explanation is:
The correct answer is:
C. Computers
Explanation:
An electronic tool that allows information to be input, processed, and output describes the fundamental function of a computer.
1. What is a Computer?
A computer is an electronic device designed to receive input data, process that data according to instructions (software), and produce output that is useful to the user. This process involves three main stages:
- Input: Receiving data or commands from input devices like keyboards, mice, scanners, or sensors.
- Processing: The central processing unit (CPU) processes the input data by performing calculations, comparisons, and other operations.
- Output: The processed information is then sent to output devices such as monitors, printers, or speakers.
Computers combine hardware (physical components) and software (programs) to perform these tasks.
2. Why Not the Other Options?
- A. CPU (Central Processing Unit): The CPU is the “brain” of the computer that performs processing of data and instructions. However, it does not handle input and output by itself. The CPU is a key component inside a computer but not the complete system.
- B. Operating System: The operating system (OS) is system software that manages the computer’s hardware resources and provides services for application programs. While essential for processing and managing tasks, the OS is not an electronic tool by itself; it runs on a computer.
- D. Motherboard: The motherboard is the main circuit board that connects all the computer components together, such as the CPU, memory, and peripheral devices. It is a hardware component, but it doesn’t perform input, processing, or output functions by itself.
3. Summary
- The question describes a system capable of input → processing → output.
- This definition matches a computer as a whole.
- Components like the CPU, OS, and motherboard are parts of the computer system but do not individually perform all these functions.
Therefore, the best answer is C. Computers.
