Chapter 9: Input-Output 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. The keyboard is the most common and widely used input device. It as an input device used to enter data into the computer system.

Show all documents Chapter-2 Input and Output Devices Speakers are one of the most common output devices used with computer systems. Some speakers are designed to work specifically with computers, while others can be hooked up to any type of sound system. Regardless of their design, the purpose of speakers is to produce audio output that can be heard by the listener. Virtual Reality — Opportunities and Challenges Virtual Reality is a technology based on computer which assimilates specialized input and output devices by allowing the user to interact with and experience an artificial created environment as if they were in the real world. A virtual reality system is also allowing the user to search and interact with a three dimensional virtual or artificial environment created by the designer.

Such devices convert between the external means of recording information required by the user, such as punched holes or printed characters, and the internal means of storing information inside the computer, such as patterns of electric signals.

Choose the correct option and mark your choice against the corresponding question number in the given answer sheet by darkening the corresponding circle with a lead pencil. Now they are also used with nonportable desktop computer systems because they occupy less table space. Non-impact printers.
What are input and output devices?
In this lesson students consider a number of computing devices to determine what types of inputs and outputs they use. Groups are assigned to a computing device and based on a teacher-provided definition of input and output, list the inputs and outputs of their device. Earlier in the activity students are prompted to focus on more obvious physical inputs and outputs e. Throughout the lesson the teacher records inputs and outputs that are identified on a T-Chart at the front of the room. To conclude the lesson students examine common activities they do on a computing device and select the inputs and outputs used for that activity from the chart. In the previous lesson students were introduced to the input, output, store, and process model of a computer. Since this model of a computer is still fairly abstract, this lesson grounds it in the ways a computer actually input and output information.
An output device is any piece of computer hardware equipment which converts information into human read able form. It can be text , graphics , tactile , audio , and video. A new type of Output device is being developed these days, known as Speech synthesizer ,  a mechanism attached to the computer which produces verbal output sounding almost like human speeches. A display device is the most common form of output device. It presents output visually on computer screen. The output appears temporarily on the screen and can easily altered or erased, it is sometimes referred to as soft copy also.
Paul's passion for technology and digital media goes back over 30 years. Born in the UK, he now lives in the US. Read on for 10 examples and the definition of an "output device. An output device is a piece of computer hardware that receives data from a computer and then translates that data into another form. That form may be audio, visual, textual, or hard copy such as a printed document.
An input device sends information to a computer system for processing , and an output device reproduces or displays the results of that processing. Input devices only allow for input of data to a computer and output devices only receive the output of data from another device. Most devices are only input devices or output devices, as they can only accept data input from a user or output data generated by a computer. For example, as shown in the top half of the image, a keyboard sends electrical signals, which are received as input. Those signals are then interpreted by the computer and displayed, or output , on the monitor as text or images.
