INPUT AND OUTPUT DEVICES In computing‚ input/output‚ or I/O‚ refers to the communication between an information processing system (such as a computer)‚ and the outside world possibly a human‚ or another information processing system. Inputs are the signals or data received by the system‚ and outputs are the signals or data sent from it. The term can also be used as part of an action; to "perform I/O" is to perform an input or output operation. I/O devices are used by a person (or other system) to

(CPU) of a computer system. A central processing unit (CPU)‚ also referred to as a central processor unit‚ is the hardware within a computer that carries out the instructions of a computer program by performing the basic arithmetical‚ logical‚ and input/output operations of the system. In the computer industry‚ the terms computer and CPU are often used interchangeably. Computing power starts with the most limited microcomputers which are laptop computers‚ netbook computers‚ PDAs and cell phones and

1. Scanning devices Optical Scanners An optical scanner is a hardware input device that allows a user to take an image or text and convert it into a digital file‚ allowing the computer to read or display the scanned object. Features of the optical scanner include-its design‚ software compatibility‚ type of feeder‚ speed‚ resolution‚ etc. Some advantages of the optical scanner include : • Easy to use • Continuous‚ detailed‚ and scaled true-colour images for documentation and interpretation

As every other organisation that produce goods or services‚ it has a precise operating system‚ composed by a range of inputs‚ a transformation process and a final output. INPUTS - We must distinguish between two different kind of resources: transformed resources‚ that are the resources treated and transformed in some way‚ and transforming resources‚ that are the resources that act upon the transformed

Question 1. Assume you are the manager of a fast-food restaurant. What are the outputs of your work unit? What are the activities required to produce those outputs? What are the inputs? When looking at a fast-food restaurant such as McDonalds‚ there are a couple main outputs that a manager needs to be aware of. The outputs include quality food and excellent service. For each of these outputs it is important to make sure that the right people are in the right positions and that they have the proper

The objective of input design is to ensure the quality‚ accuracy‚ completeness‚ and timeliness of input data during its conversion from its original source into computer data‚ or entry into a computer application. Data can be entered into a computer application from either manual online input or by scheduled automated processing. Input controls will ensure that data is accurately processed through the application and that no data is added‚ lost‚ or altered during processing (Shu‚ unk). No matter
