Input and output devices of computer : Computer input devices are used to give instructions to the computer and output devices display the results of operations carried out by the CPU (central processing unit) or other electronic components. These input/output systems work with the operating system (OS), software, application programs. in this post we are sharing a list of input , output and both input output devices of a computer.
We use Input devices to enter data and instructions into a computer system. Input devices are used to input data into a computer or send commands to the operating system in order for application software to execute desired amples. Here is the list of input devices of computer :
- Graphics Tablets
- Video Capture Hardware
- Barcode reader
- Digital camera
- MIDI keyboard
- Electronic Whiteboard
- Pen Input
- Punch card reader
- MICR (Magnetic Ink character reader)
- Magnetic Tape Drive
Output devices are part of the output section of a computer system. They output the results produced by a program or computer upon completion of its execution. An output device can be a monitor, printer, plotter or speaker. The output device is connected directly to the output of the output section of a computer’s central processing unit. Here is the list of output devices of computer-
- LCD Projection Panels
- Head Phone
- Computer Output Microfilm
- Visual Display Unit
- Film Recorder
Both input and output devices list :
In computer, there are some devices which used as input and output devices. Here is the list of both Input–Output Devices-
- Touch Screen
- Network cards
- Audio Cards / Sound Card
- Headsets (Headset consists of Speakers and Microphone.
- Speaker act Output Device and Microphone act as Input device
- Facsimile (FAX) (It has scanner to scan the document and also have printer to Print the document)
Related Questions about Input and output devices of computer :
Input and output devices are crucial to a computer’s operation. The input device is what you use to communicate with the computer, while the output device is how you receive information back from the computer. Input devices include keyboards, mice, touchpads or trackballs, joysticks, drawing tablets and digital pens. Output devices include monitors (TVs), speakers and printers. Input and output devices have changed dramatically over time as technology has advanced.
The input and output devices are the parts of a computer that allow users to interact with the machine. Inputs include keyboards, mice, joysticks, trackballs and touch screens. Outputs include monitors, printers, speakers and headphones. Today’s computers can control just about any electronic device in your home or office – from your TV set to your oven!
In computer system the input and output devices are used to communicate with outside world. So that these devices perform as an interface between the user and the computer system. Here a little bit of distinction is necessary between input and output devices because they serve different purposes at first glance and sometimes the same device can be used as an input device and output device.
If a computer is used to store information it means data entry in the form of text or digital, binary numbers (mathematical operations) can be entered using keyboard as an input device. Input devices are used for entering the data in computer.
Output devices are used to display information in the form of text or digital, binary numbers read by the computer. An output device is a part of a computer that displays data. Output devices are used for displaying the data from the computer.
We can use monitor as an example of output device and keyboard as an input device for simplifying the concept. Input devices are also called as user interface devices in computer science because they allow the user to communicate with the computer. Output device is also called as output peripheral or output device in computer science because they are a part of output peripheral which senses any data from the computer and display it to outside world.
There are some device can be used as both input and output device. Touch Screen, Modems, Network cards, and Audio Card / Sound Cards are the example of both input and output devices of computer.
