Printer Plotter Scanner Sound card Speakers Projector Tape drive. Aug 18, · There are many different peripheral devices, but they fall into three general categories: Input devices, such as a mouse and a keyboard Output devices, such as a monitor and a printer Storage devices, such as a hard drive or flash drive.
Such devices make up the peripheral equipment of modern digital computer systems. Peripherals are commonly divided into three kinds: input devices, output devices, and storage devices which partake of the characteristics of the first two. An input device converts incoming data and instructions into a pattern of electrical signals in binary code that are comprehensible to a digital computer.
An output device reverses the process, translating the digitized signals into a form intelligible to the user. At one time punched-card and paper-tape readers were extensively used for inputting, but these have now been supplanted by more efficient devices.
Input devices include typewriter-like keyboards; handheld devices such as the mousetrackball, joystick, trackpad, and special pen with pressure-sensitive pad; microphones, webcams, and digital cameras.
They also include sensors that provide information about their environment— temperaturepressureand so forth—to a computer. Another direct-entry mechanism is the optical laser scanner e. Output equipment includes video display terminalsink-jet and laser printers, loudspeakers, headphones, and devices such as flow valves that control machinery, often in response to computer processing of sensor input data. Some devices, such as video display terminals and USB hubs, may provide both input and output.
Computerr examples are devices that enable the transmission and reception of data between computers—e. Even devices such as smartphonestablet computersand how to make zero the ghost dog devices like fitness trackers and smartwatches can be considered as peripherals, albeit ones that can function independently.
Various standards for connecting peripherals to computers exist. For example, serial advanced technology attachment SATA is the most common interface, or busfor magnetic disk drives. A bus also known as a port can be either serial or paralleldepending on whether the data path carries one bit at a wuat serial or many at once parallel. Serial connections, which use relatively few wires, are generally simpler than parallel connections.
Universal serial hwat USB is a common serial bus. Peripheral device Article Media Additional Info. Home Technology Computers Peripheral device computer technology. Print Cite verified Cite.

Why are the keyboard and mouse a peripheral?
Peripheral device, also known as peripheral, computer peripheral, input-output device, or input/output device, any of various devices (including sensors) used to enter information and instructions into a computer for storage or processing and to deliver the processed data to a human operator or, in some cases, a machine controlled by the computer. Such devices make up the . Jul 14, · Other computer peripherals are image scanner, microphones, graphic cards, expansion cards, webcams etc. RAM (Random Access Memory) is the line between primary component and peripheral, technically it is a storage peripheral, but it is an essential component of computer, removing which will make it unworkable. Sep 01, · A peripheral device is defined as a computer device, such as a keyboard or printer, that is not part of the essential computer (i.e., the memory and microprocessor).These auxiliary devices are intended to be connected to the computer and used.
Peripherals are devices that are not the computer's core architecture involved in memory and processing. Peripherals include input hardware, output hardware and storage devices.
A typical desktop computer could include:. Peripherals connect to the processor hardware through the motherboard. External devices will connect to the motherboard via USB , FireWire or through a wireless connection such as Bluetooth. GPIO ports are generic input and output ports that can be controlled directly by software. They are used on the circuit boards of computers like the Raspberry Pi and Arduino.
They provide low-level connections that can be connected to switches, LED lights or electric relays. They can be used in programs to control systems such as a DIY burglar alarm or central heating system.
Smartphones , desktop and laptop computers do not have GPIOs. It can be easy to create your own basic peripheral using a Raspberry Pi, Arduino or other simple computing device.
Introducing peripherals Peripherals are devices that are not the computer's core architecture involved in memory and processing. A typical desktop computer could include: inputs - mouse, keyboard, webcam, games controller outputs - screen, printer, speakers, headphones storage - hard drive Connections Peripherals connect to the processor hardware through the motherboard.
