Input and Output Devices Input devices and output devices are terms that are readily used in everyday communication in the digital age. An input device, as the name suggests, is a device that sends information to a computer so that it can be processed. Likewise, an output device, displays or produces the end-product of processing. “The terms “input” and “output” are used both as verbs to describe the process of entering or displaying the data, and as nouns referring to the data itself entered into or displayed by the computer” (Beach). A device can either be an input device or an output device or both depending upon the interaction. Devices that serve as both input device and output device are termed as I/O devices.
An example of input device is a keyboard. Using the keypad, a user types the data. A keyboard sends electrical signals to the computer system, which is essentially the input. The computer then interprets the signals so that the results can be displayed in the form of text on a monitor. In this example, the text is output. In an another example, a computer sends data to a printer and it generates a printed paper. Here, computer is the input device whereas printer is the output device. The input and output may vary in their nature and form depending upon the mechanism. For example, when a computer sends information into a printer as signals, the input is digitized information whereas its output is a tangible printed paper.
It is important to note that an input device e.g. a mouse or the keyboard of a computer can perform the function of sending information to a computer as input. However, these input devices cannot reproduce or receive any information from the computer as output. It is also noteworthy that the input or output classification of devices is relative to each other. This can be elaborated from the example of a USB inserted in the port of a computer and a lead connecting the computer to a printer. Here, while the computer serves as an output device for the USB in that it generates the signals, the computer plays the role of an input device for the printer because eventually, the text will be printed as output by the printer. A USB flash drive and a CD-RW drive are both examples of I/O devices as both can send as well as receive information from a computer.
To conclude, input devices send information into a system whereas output devices generate its results. Some devices can only be either input devices or output devices whereas others can be both. The status of a device as an input device or an output device depends upon its interaction with other devices. Recognizing the function of a device as an input device or an output device is very important in establishing a functional mechanism in any setup. Identification of the devices’ roles lays the basis of making a logical network of devices to produce the desired results.

Input Output Devices of a Computer

... Input Output Devices of a Computer Computer is an electronic machine that works in an efficient manner to manage and organize the information. The information given to the computer is called the "data". This information is in the crude form and can be processed in the desired form to give the result as the output. Computer is prevalent because of its accuracy, speed and storage capacity. The information given to the computer is called the input. The input is given by the input devices which help the user to interact with the computer. Output devices display the result after the computer processes the information given or the input provided. Most prevalent input devices are the keyboard and the mouse. Keyboard is similar... to the...

Assignment 3: Input Controls

...INPUT CONTROLS Lecturer: Functions of input controls Input controls are edits that pass data into an application or gather information from a user. They allow the user to perform a variety of functions; type in text, select items, upload files and much more. Input controls can also be used to enforce transaction data integrity in the application. If incorrect data is entered into the system undetected, it might crush the system or corrupt its functionality. The input control therefore, minimizes the risk (Guadiso 85). Input controls are also used to check validity of information passed to the systems by providing validation checks....

Input and output

...Computer Input Output For a computer to process data, the data needs to be in place within the computer; thus, thereis the need to have a mechanism in which data can be input into the computer. In the same way, after the data input into the computer is processed, there is a need for it to be displayed so that a computer user can view the product. It is because of these two aspects of computers that there is a need to review what input and output in computer means in terms of processing, and its relevance in computing altogether. Input is based on a number of devices that facilitate the placing of data...

Facts about input output

...Facts about inputs and outputs Inputs are necessary for a computer system to provide outputs. Input commands are processed by the central processing unit (CPU) which contains two separate divisions; one for arithmetic operations and the other for logical operations. Raw data is given to the CPU whereas finished data is delivered by the CPU. In other words, raw data is given through inputs while finished data is obtained through outputs from a computer system. Various equipment are used for inputting data and to obtain the outputs from a computer system. Input and...

Main Material Input and Output

...P2 Opportunities in the Metallurgical Industry This paper briefly describes the main material inputs and outputs associated with the metallurgical industry. It is important to be aware of input as well as output production information. This is because “…the total of what goes into a process must equal the total of what comes out…” (Cheremisinoff, 2001, 185). This is in order to be able to balance the production material and output material, especially in relation to emissions. If waste can be reused in the production process, it may not count as an output and can, therefore, assist in controlling emissions (Cheremisinoff, 2001, 179). As well, this paper names and discusses three potential P2 opportunities for the industry... Opportunitie...
