Output Device can produce the final product of machine processing into a form usable by humans.
The devices are usually used for display, projection, or for physical reproduction. Monitors and printers are two of the most commonly-known output devices used with a computer. A computer can still function without an output device.
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. In the lower half of the image, the computer sends, or outputs , data to a printer. Then, that data is printed onto a piece of paper, which is also considered output.
An input device is essentially a piece of hardware component used to provide data and control signals to an information processing system such as computer or information device. Common inputs devices on modern computers include keyboards, mouse and touch screen which are used to enter commands and data directly. Other examples of input devices include scanners, digital cameras, joysticks and microphones. An output device is any hardware component that use received data from a computer to perform a task. The data received by the output device can be text, graphic, tactile, audio or video. Three most commonly used output devices are a printer, a monitor and speakers. A printer is used to generate a hard copy or graphics on a physical medium such as paper.
For other information, see the Ghostscript overview. You may also be interested in how to build Ghostscript and install it , as well as the description of the driver interface. Documentation for some older, superceded devices has been moved to another document. In general such devices are deprecated and will be removed in future versions of Ghostscript. In general all older printer drivers can be replaced by the ijs interface and one of the available 3rd party raster driver collections. We recommend moving to the ijs device for all such printing.
Input and output devices of a computer system are the devices that connect you to computer. Input per second. Thus, a study of the first method, i.e. manual input They can print finer, smoother details through higher print head resolution.
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.
Keyboard is the most common and very popular input device which helps to input data to the computer. The layout of the keyboard is like that of traditional typewriter, although there are some additional keys provided for performing additional functions. These keys include the letter keys A-Z and digit keys 09 which generally give the same layout as that of typewriters. It is used to enter the numeric data or cursor movement. Generally, it consists of a set of 17 keys that are laid out in the same configuration used by most adding machines and calculators. The twelve function keys are present on the keyboard which are arranged in a row at the top of the keyboard. Each function key has a unique meaning and is used for some specific purpose.
