An Input device is a hardware component that is used to enter data and instructions into a computer. There are three general types of Input devices: 1)Keyboards 2)Pointing devices(e.g:mouse,pointing stick,touch screen,graphic tablet, joy stick etc) 3)Source data entry devices(e.g:(1)scaning devices i.e;barcode reader,magnetic-ink character recognition reader(MICR), smart cards, imaging system, etc and (2)audio/video devicesi.e; audio input devices, video input devices and digital camera)
1.Manual input devices 2.Direct data entry devices I dont know the third one if u find out let me know lol.
Devices for communication between computers, such as modems and network cards , typically serve for both input and output. Also, a touch screen can be considered as an input and output. 1.Modems 2.Network Cards. 3.Touch Screen. 4.Headsets. 5.Facsimile (Fax). 6.Audio Cards/Sound Card.
computer is mainly divided into 3 parts, 1.input devices 2.processing unit 3. output devices. In which , keyboards and computer mice fall in input devices by which we can send data/instruction into processing unit which is called CPU. And result will be displayed through output devices.Monitors and Printers are output devices.
The two main types of external hardware are input devices and output devices. Input devices, such as keyboards and mice, allow users to enter data into a computer, while output devices, like monitors and printers, display or produce the results of computer processes. Together, they enhance the functionality and user interaction with computers.
Two common hardware input devices are the keyboard and the mouse. The keyboard allows users to input text and commands through various keys, while the mouse enables point-and-click navigation on a screen. Both devices are essential for interacting with computers and executing tasks efficiently.
Webcame Barcode reader Fingerprint scanner Image scanner
Optical inout devices that uses light as a source of input. They eliminate the need for manual entry of data, thus accuracy increases. Three examples of optical input devices are: 1. barcode reader 2. image scanner 3. light pen Barcode readers convert a barcode (pattern of bars on products) to a code that computers can understand. Image scanners are of two types,flat bed and hand-held. Light pens use a light sensitive detector.
CPU is neither an input device nor an output device. It is the central processing unit. Unit which takes inputs from input devices like keyboard, mouse, sound input etc. does the processing as per the application running on the machine and gives an output to output devices like screen display, a printer or sound output.
