Which Of The Following Is Not A Computer Peripheral

Which of the Following is NOT a Computer Peripheral? Understanding Peripheral Devices

This article will explore the definition of a computer peripheral and identify which of several common computer components is not classified as one. We'll clarify the distinction between internal components and external peripherals, providing a clear understanding for both beginners and those looking to refresh their knowledge. Understanding peripherals is crucial for effective computer troubleshooting and system management.

What is a Computer Peripheral?

A computer peripheral is any external device that connects to a computer to provide input, output, or storage capabilities. These devices expand the functionality of the central processing unit (CPU) and its immediate supporting components like RAM and the motherboard. They are typically connected via ports like USB, Thunderbolt, or specialized interfaces.

Examples of common computer peripherals include:

• Input Devices: Keyboards, mice, scanners, microphones, webcams, game controllers, touchscreens (external).
• Output Devices: Monitors, printers, speakers, headphones, projectors.
• Storage Devices: External hard drives, USB flash drives, CD/DVD drives.

Internal Components vs. Peripherals

The key distinction lies in the physical location and integration within the computer system. Internal components are physically housed inside the computer case and are essential for the computer's basic operation. Peripherals, on the other hand, are external and can be connected and disconnected without affecting the core functionality (though their absence might limit functionality).

Identifying the Non-Peripheral:

Let's consider a typical desktop computer setup. Many components might initially seem peripheral, but upon closer inspection, some are clearly integral parts of the computer's internal architecture.

Here's a hypothetical list, with the non-peripheral highlighted:

• A. Graphics Card (GPU): While having external connections (HDMI, DisplayPort), the GPU is typically installed inside the computer case and directly interacts with the motherboard and CPU. It's an internal component.
• B. Mouse: Clearly an external input device.
• C. Printer: An external output device.
• D. External Hard Drive: An external storage device.
• E. CPU (Central Processing Unit): The brain of the computer, residing inside the case. It's an internal component.
• F. Monitor: An external output device.
• G. RAM (Random Access Memory): Found on the motherboard inside the computer. It's an internal component.
• H. Keyboard: An external input device.

Therefore, A, E, and G (Graphics Card, CPU, and RAM) are not considered computer peripherals. They are integral internal components. A computer simply cannot function without them. The other components listed are all external peripherals, and their connection or absence affects the computer's capability but not its basic ability to operate.

Conclusion:

Understanding the difference between computer peripherals and internal components is crucial for both basic computer literacy and advanced troubleshooting. Remembering that peripherals are external devices that expand the computer's capabilities, while internal components are essential for the computer's core functionality, will help you easily identify which is which in any given scenario.
