Input Data is factual information and it needs to be accurately captured in order to be processed. There are many methods to input data and each situation warrants a different method. There can be several different ways to input the information and it can be done in an automatic fashion‚ as with a computer‚ or it can be done manually‚ as with a human writing the information down. For instance‚ printed questionnaires would best use a special scanning device called an optical data reader that uses

Many of these features save energy by enabling electronics to expend the minimum amount of energy necessary to provide appropriate screen illumination levels. For example‚ when a phone is held to a user’s ear during normal conversation‚ the user can not see the screen‚ and therefore it may be turned off. This

Introduction Computer is a machine that can be programmed to accept data (input) process it into useful information (output) and stored it away (in a secondary storage device) for safekeeping or later reuse. The processing input to output is directly by the software but performed by the hardware. To function‚ a computer system requires four main aspect of data handling: Input Processing Output Storage Secondary

Input devices 1.Keyboard In computing‚ a keyboard is an input device‚ partially modeled after the typewriter keyboard‚ which uses an arrangement of buttons or keys‚ to act as mechanical levers or electronic switches. A keyboard typically has characters engraved or printed on the keys and each press of a key typically corresponds to a single written symbol. However‚ to produce some symbols requires pressing and holding several keys simultaneously or in sequence. 2. Mouse In computing‚ a mouse

Input Device is any peripheral (piece of computer hardware equipment) used to provide data and control signals to an information processing system such as a computer or other information appliance. A keyboard is the most common input device. Using a keyboard‚ the user can type the text and execute commands. Keyboard is designed to resemble a regular typewriter with a few additional keys. Data is entered into the computer by simply pressing various keys. The layout of a keyboard comes in various

Once data have been captured‚ they usually must be processed to be valuable to decision makers and these processing tasks are performed by the central processing unit (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
