Which of these is not a peripheral in computer terms?

A peripheral, in computer terms, refers to any device that connects to a computer and enhances its functionality. These devices can range from input devices like keyboards and mice to output devices like monitors and printers. However, there is one device that is not considered a peripheral in computer terms: the Central Processing Unit (CPU).

The CPU is the critical component within a computer system that carries out instructions and performs calculations. It is the core of the computer, responsible for executing programs and managing the flow of data within the system. Unlike peripherals, which are connected to the CPU, the CPU itself is an integral part of the computer system and not considered an external device.


1. What are some common examples of peripherals?

Some common examples of peripherals include keyboards, mice, printers, scanners, monitors, speakers, and external storage devices like USB drives.

2. Why is the CPU not considered a peripheral?

The CPU is not considered a peripheral because it is an internal component of the computer system rather than an external device that connects to it.

3. What is the function of the CPU?

The CPU performs calculations, executes instructions, and manages the flow of data within a computer system.

4. Do peripherals require a CPU to function?

Yes, peripherals require a CPU to function. They rely on the CPU to process their input and deliver the appropriate output.

5. Can peripherals be connected to the CPU?

Peripherals are connected to the CPU via ports, slots, or wireless connections to facilitate communication and exchange of information.

6. Are all peripheral devices essential for computer operation?

No, not all peripheral devices are essential for computer operation. While some peripherals like keyboards and monitors are necessary, others like printers or scanners may be optional depending on the user’s needs.

7. Can a peripheral device become non-functional?

Yes, like any electronic device, a peripheral can become non-functional due to various reasons like hardware failure, software compatibility issues, or physical damage.

8. Can a computer work without any peripherals?

Technically, a computer can work without any peripherals, but it would be challenging to interact with or get any meaningful output from the system without them.

9. Is the CPU the most crucial component of a computer system?

Yes, the CPU is often considered the most crucial component as it processes instructions and data, determines the system’s speed and power, and acts as the brain of the computer.

10. Are peripherals specific to desktop computers only?

No, peripherals are not specific to desktop computers only. They can be used with various devices like laptops, tablets, and even smartphones to enhance their functionality.

11. Can peripherals be connected to multiple computers simultaneously?

Some peripherals like network printers or shared storage devices can be accessed by multiple computers simultaneously, but this depends on the specific peripheral and its connectivity options.

12. Can a peripheral device affect the performance of a computer system?

Yes, a malfunctioning or incompatible peripheral device can impact the performance of a computer system. It may cause system crashes, slow down processes, or hinder overall functionality.
