This is the termed as input Processing output cycle .A computer receives data as input ,processes it, Stores it and then produces output. Input, Process, Output, and Conventional Technology To provide a better understanding of input, output, and processing, these concepts are defined as follows. Input – the information entered into a computer system, examples include typed text, mouse clicks, etc. Processing – the process of transforming input information into an output.
It function in the following.
Computer input is whatever is enteret or fed into a computer system.Input can be supplied by a person (such as by using a keyboard) or by anther computer or device (such as a diskette or SD-ROM).Some example of input include the wodrs and symbols in a document,NUMBER FOR A CALCULATION,instruction for completing a process,Picture,And so on.
The computer performs a useful operation by manipulating the data in many ways. This manipulation is called processing.
Example:-Example of processing include performing calculations, sorting lists of words or number, Modifying documents and picture according to user instruction, and drawing graphs.A computer processes data in the CPU
The computer stores data. A computer must data so that it is available for processing. The most computer has more than one location for storing data(The hard drive or c:\, and the floppy drive or A:\). The computer puts the data in one place while it is waiting to be processed and another place when it is not needed for immediate processing.
The computer produces output. Computer output is information that has been generated by a computer. So an example of computer output includes reports, documents, music, graphs, and picture. Output can be in several different formats, Such as paper, diskette,or on screen.
An input device can send data to another device, but it cannot receive data from another device. Examples of input devices include the following.
- Keyboard and Mouse: – Accepts input from a user and sends that data (input) to the computer. They cannot accept or reproduce the information (output) from the computer.
- Microphone:– Receives sound generated by an input source, and sends that sound to a computer.
- Webcam:– Receives images generated by whatever it is pointed at (input) and sends those images to a computer.
An input-output device can receive data from users, or another device (input), and send data to another device (output). Examples of input/output devices include the following.
- CD-RW drive and DVD-RW drive: – Receives data from a computer (input), to copy onto a writable CD or DVD. Also, the drive sends data contained on a CD or DVD (output) to a computer.
- USB flash drive: – Receives, or saves, data from a computer (input). Also, the drive sends data to a computer or another device (output).
