Computer and its Basic Operations:

                                                                                                             All Computer performs four basic operations: input, processing, output, and storage to carry out any task. The four basic operations if computer are:

1) Input Operation:

                                It is the process of capturing or accepting data or information, by using input devices. Input can take a variety of forms, from commands we enter by the keyboard to data from another computer or device.

2) Processing Operation:

                                         It is the transformation process to convert the input into output. The CPU performs processing tasks under the direction of a program. To process the data, the CPU stores the program instructions and the data in the computer's memory, where it is directly accessible for processing.

3) Output Operation:

                                   It is the result, which comes from the transformation process or it is the outcome of the processing. The monitor shows the results of processing operations on the screen. Speakers  enable users to hear the results of sound  processing. The printer generates output on paper.

4) Storage Operation: 

                                  It is the process of storing the data or information or instructions, so that the user can retain and retrieve it whenever required. Computer data storage is referred to as storage or memory, which can save digital data. Examples are RAM, Hard Disks or removable memory sticks, etc
