What is an Output Device? - Computer Hope.

Input Devices. Input device enables the user to send data, information, or control signals to a computer. The Central Processing Unit (CPU) of a computer receives the input and processes it to produce the output.

Keyboard: A keyboard is the most common input device. Generally standard keyboard has 104 keys. 2. Mouse: A mouse is an electro mechanical, hand held device. It is used as a pointer. It can perform functions like selecting menu commands, moving icons, resizing windows, starting programs, and choosing options. 3. Light pen: An input device that utilizes a light-sensitive detector to select.

Other common input devices are joysticks, bar code readers, cameras, fingerprint readers, etc. CD and DVD drives are also input devices, since they read data into the computer. Another classification of a peripheral is an output device. Output devices translate information stored in the computer and present it in a way that humans can understand it. Typical output devices in a computer system.List of Input Output Devices Click To Tweet. Touchpad: A touchpad or trackpad is a kind of input device that has a limited area wherein you can Point, scroll, click and swipe. A Touchpad most commonly found on computer laptops (computer brand doesn’t matter). Touchpad allows to use all the features as you do with a computer mouse. TrackPoint: Most commonly TrackPoint found in IBM ThinkPad.Input Cabinet of CuriositiesDesigners have been playfully creative in finding ways for humans to talk to machines. They've given us keyboards, mice, trackballs, joysticks, tablets, switches, gloves, light pens, microphones, cameras, and more. Each is best for a particular application.It is still an active area for innovation, so watch for even more creative ideas in the future.


The most common Bluetooth devices are Class 2 devices, with a range of 10 meters. Examples of this include portable printers, headsets, and computer dongles that connect to USB ports and allow the PC to communicate with other Bluetooth-enabled devices. Input, Output, and Hybrid Devices.Most likely in front of you right now are two of the most popular input devices: the keyboard and the mouse. And instead of a mouse on a laptop computer you normally have a touchpad. As computers evolved throughout the late 20th century, computers became more and more interactive. Input devices came and went. Some lasted and some did not.

Most output devices require that the computer convert the digital format back into analog signal. Video consists of images that are played back at speeds that provide the appearance of full motion. Video often is captured with a video input devices such as a camera or VCR.A video capture card converts an analog video signal into a digital that a computer can understand. The digital signal then.

Answer (1 of 21): Input and output devices on a computer allow users to interact with a computer in a meaningful way. While some devices are strictly for either input or output, others may be used for both. Others still may be used for input, output and storage.Input DevicesSome of the most common input devices are pointing devices, such as the mouse, trackball or touch pad.

A common computer input device, a. Pointing devices are the most commonly used input devices today. A pointing device is any human interface device that allows a user to input spatial data to a computer. In the case of mouse and touchpads, this is usually achieved by detecting movement across a physical surface. Analog devices, such as 3D mice, joysticks, or pointing sticks, function by.

Output and input devices are two types of hardware devices. The main difference between them is that input devices are used to send data into the computer while output devices are used to take data out of the computer. Most devices are either input devices or output devices, as they can only accept data input from a user or output data.

A common method of obtaining bulk output is via a device known as a line printer. A line printer prints a complete line at a time. The speeds of line printers range from 200 to 3000 lines per minute. The slowest line printer is thus 100 times faster than manual typing. Line printers print characters at a constant pitch, typically of 10 characters per inch with a total of 132 characters per line.

There are many different types of sensors and transducers, both analogue and digital and input and output available to choose from. The type of input or output transducer being used, really depends upon the type of signal or process being “Sensed” or “Controlled” but we can define a sensor and transducers as devices that converts one physical quantity into another.

A pointing device, or sometimes called a pointing tool, is a hardware input device that allows the user to move the mouse cursor in a computer program or GUI operating system. Using a pointing device, you can point at or manipulate any object or text on the screen. For example, using a pointing device you could point at and select an icon from a list of icons.
