7. PERIPHERAL DEVICES

A peripheral device is generally defined as any auxiliary device such as a computer mouse or keyboard that connects to and works with the computer in some way.

Peripheral devices, often referred to as peripherals, are hardware components or devices that are connected to a computer or other digital device to provide additional functionality, input, or output. These devices extend the capabilities of the main computer system and allow users to interact with, control, or exchange data with the computer. Peripheral devices are typically not an integral part of the central processing unit (CPU) or the core system components but serve specific purposes. Other examples of peripherals are expansion cards, graphics cards, image scanners, tape drives, microphones, loudspeakers, webcams, and digital cameras

Common examples of peripheral devices include:

1.     Input Devices: These devices allow users to input data or commands into the computer.

• Microphones: Capture audio input for voice recognition or audio recording.

2.     Output Devices: These devices provide information or results from the computer to the user. Examples include: o            Monitors: Display the visual output of the computer, including text, images, and videos.
