The document discusses computer input and output devices. It defines a computer as an electronic device that processes data into useful information. Common input devices include keyboards, mice, scanners, joysticks, light pens, microphones, and barcode readers, which are used to enter data and instructions. Output devices like monitors, speakers, printers, and webcams display or present the processed information from the computer.
Types of input-output devices
Input devices such as keyboards, mice, scanners, and touchscreens convert human instructions and data into a format computers can understand. These devices allow users to enter information and control the computer. Output devices like monitors, printers, and speakers take the processed data from computers and present it to users in a human-readable form such as displaying images or playing sounds.
Input and output devices.pdf
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 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.
