Computer Processing and Processing Devices
A Computer processing device is the part of the computer that receives input, processes the input and gives output. A computer can add large numbers and make other complex calculations and give you the result in just a few seconds.
The body of the computer is the hardware such as CPU, VDU, etc. These are the mechanical and electronic parts which can be seen and touched. A computer executes commands and instructions.
Almost all the systems and the machines that we find around us work in the same way. They accept some input. These inputs are processed in a specific manner to produce some Output. For example, we take oranges, put them in the juicer, switch it on and finally we get orange juice.
The IPO Cycle is termed as Input-Processing-Output cycle. A computer receives data as input, processes it, stores it and then produces output.
This Input-Process-Output (I ? P - O) cycle is represented in the following figure:
An input devices is any machine that feeds data into a computer.
The computer performs useful operations by manipulating the data in many ways. This manipulation is called processing examples list of words or numbers, modifying documents and pictures according to user instructions and drawing graphs. A computer processing data in the CPU.
When you ask a question to someone they take in the input process and give the output. Your brain does it every second, it uses eyes, nose, mouth etc.., as input devices and then processes the information that they fed it and then tell you are seeing, eating or listening to.
For example as you seen in real life, cooking, - The ingredients are the inputs, cooking them is the process and the food prepared is the output in computer.
Output can be meaningful information and can appear in a variety of forms as numbers, characters, pictures and printed pages.
