INPUT, PROCESS, OUTPUT (IPO)

The computer is in a constant cycle of input, process, and output. The computer waits for you to enter the required information (input). Based on the entered information, the computer takes the appropriate actions (process). Finally, the result is displayed on the screen or printed out (output). An analogy for input, process and output would be a food processor where food, fruit and other ingredients are put into the machine. Afterward, based on the selected setting, such as cutting, chopping, or mixing, the food processor performs the appropriate task, and finally the desired mixture is ready to be used.
