A peripheral is a device that is connected to a computer to enhance or extend its functionality. Peripherals can be divided into several categories based on the type of device they are, including input devices, output devices, storage devices, and communication devices.
Input devices include keyboard, mouse, and scanner, which are used to input data into the computer. Output devices include displays, speakers, and printers, which are used to display or produce information. Storage devices, such as hard disk drives and solid-state drives, are used to store data. Communication devices, such as modems and network adapters, are used to connect the computer to other computers or to the Internet.
Peripherals are important components of a computer system, as they allow users to interact with and use the computer in a variety of ways, and they also allow users to expand the computer’s capabilities.
