What is meant by the term 'peripheral' in relation to computer hardware?

• A. An internal component of the computer
• B. An external device connected to a computer
• C. A type of software used for system maintenance
• D. A network device facilitating internet access

Answer: (B)

The term 'peripheral' in relation to computer hardware refers to an external device connected to a computer. Peripherals serve as supplementary devices that enhance the functionality of the main computer system but are not essential for it to operate. Examples include keyboards, mice, printers, scanners, and external drives. These devices allow users to interact with the computer, input data, and retrieve output, or they may provide additional storage and other capabilities.

Understanding peripherals is essential as they facilitate user interaction and expand the range of tasks that a computer can perform. Internal components, like the CPU or RAM, are crucial for the computer’s basic operation but are not classified as peripherals because they are not external and do not connect through ports designed for peripherals. Software does not fit the definition of hardware and thus does not fall under the peripheral category. Network devices that provide internet access are specific in function and are more accurately described as networking hardware rather than peripherals.
