2. Scanner
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)
KeyboardMouse
A device which connects to the computer is called a "peripheral."
* Keyboard * Scanner * Mouse
Input devices : 1). Keyboard 2). Mouse 3). light pen Output devices: 1). Plotter 2). Screen
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.
1.Manual input devices 2.Direct data entry devices I dont know the third one if u find out let me know lol.

1.) Cable Modem 2.) DSl Modem 3. ) Dial-up Modem
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.
1.the form factor of the case 2. the voltage requirements of peripheral devices
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.
