Here's a list of input output devices.
GROUP 4Input & Output DevicesINPUT DEVICESWHAT ARE INPUT DEVICES? As the name suggests, input devices are hardware devices that allow data to be entered into the computer. It helps you communicate with the computer. Many such devices exist, ranging from the more common ones, such as keyboard, through to the more specialist devices such as barcode readers.
Input Output Devices2KeyboardThe keyboard is the most common and widely used input device. It as an input device used to enter data into the computer system.At its essence, a keyboard is a series of switches connected to a microprocessor that monitors the state of each switch and initiates a specific response to a change in that state.
Input Output Devices3Types of keyboardsInput Output Devices4MouseA mouse is an input devices that fits comfortably under the palm of your hand.A mouse is a pointing device.We use mouse to control the movement of the cursor on the screen and to make selections from the screen.The bottom of a mouse is flat and contains a mechanism that detects the movement of a mouse.Input Output Devices5Types Of MouseInput Output Devices6
ScannerA scanner is an input device that scans documents such as photographs and pages of text. When a document is scanned, it is converted into a digital format. This creates an electronic version of the document that can be viewed and edited on a computer.
Input Output Devices7Two most common types of scanners:-Flatbed Scanner-The most popular. Operate in a similar way to photocopiers. Most common size of documents are of A4 size. Handheld- Handheld scanners are more portable than flatbed. Different sizes of document can be scanned more readily than flatbed scanners.

MicrophoneMicrophones can be used to allow a computer to convert sounds into data that it can handle.
A microphone allows you to record your voice to the computer.
It also lets you speak to other people using computers or even on the telephone.
A microphone is also called a mic.Input Output Devices11Microphones can be used to add speech to number of different applications like a presentation.
It also allows peoples speech to be translated into text.
Far easier to use then a keyboard.
Microphones can also be used to recognize a command. Eg. :- Some cars now have voice activated systems to switch on the lights, turn the radio volume etc. Mobile phones also use the service of a microphone for performing various functions. Input Output Devices12
Output DevicesAn output device is any piece of computer hardware equipment used to communicate the results of data processing carried out by an information processing system (such as a computer) to the outside world.Input Output Devices13
MonitorMonitor is a TV like device that display information on screen.It can display text as well as graphic images in color or black & white while based on monitor type.Monitors are classified on the basis of color and signals.Screen output is referred to as soft copy.
