Today, the most common connection for external peripherals is the USB connection, both because most computers have several ports available, and because of the simplicity of the plug-and-play feature. Storage peripherals are used to store and record data, and include internal and external hard drives, CD-ROM and DVD drives, and flash memory drives.ĭepending on whether the peripheral is located inside or outside the computer system case, it can be further classified as an internal or external peripheral device.Īn external peripheral can be connected via many different types of cables and connections. Some devices can provide both input and output signals, such as network interfaces, modems, routers, and webcams.
Other output peripherals include speakers, 3D printers, and projectors. For example, a monitor or display screen will show the operating system’s desktop, while a laser printer will translate information saved in a word file into printed material. Output peripherals translate digital signals into information that can be interpreted or utilized by the end user. Other input peripherals include joysticks, microphones, webcams, optical scanners, etc. For example, a keyboard will convert keystroke into characters that appear on the computer’s display, while a monitor will transform hand movements into movements of a cursor that can be used to interact with the operating system’s programs. Input devices convert incoming instructions or actions from the user into viable information that can be interpreted by the computer. There are several types of peripherals, although they’re commonly divided into three broad categories: input, output, and storage devices. Peripheral devices include the following:

Look up peripheral in Wiktionary, the free dictionary.A peripheral device provides input/output (I/O) functions for a computer and serves as an auxiliary computer device without computing-intensive functionality. Many modern electronic devices, such as Internet-enabled digital watches, keyboards, and tablet computers, have interfaces for use as computer peripheral An input/output device performs both input and output functions, such as a computer data storage device (including a disk drive, solid-state drive, USB flash drive, memory card and tape drive), network adapter and multi-function printer.An output device provides output data from the computer, such as a computer monitor, projector, printer, headphones and computer speaker.An input device sends data or instructions to the computer, such as a mouse, keyboard, graphics tablet, image scanner, barcode reader, game controller, light pen, light gun, microphone and webcam.Several categories of peripheral devices may be identified, based on their relationship with the computer:

In other words, peripherals can also be defined as devices that can be easily removed and plugged into a computer system. The term peripheral device refers to all hardware components that are attached to a computer and are controlled by the computer system, but they are not the core components of the computer, such as the CPU or power supply unit. Auxiliary input/output device for a computerĪ peripheral or peripheral device is an auxiliary device used to put information into and get information out of a computer.
