Full Form of IPO Cycle, Computer Elements, and Key Points

The term IPO stands for the input-process-output model. The input and output of the information processing process is the IPO cycle. People must provide input before receiving output, and the input must then be processed to produce the intended result. 

First comes the input. It is responsible for providing the computer with specific data or instructions. A mouse, keyboard, or even your speaker utilizing voice commands can be used to complete the task. In addition, after receiving the data, the computer first processes it. Therefore, your orders are carried out by the central processing unit, or CPU. 

Data and instructions are both included in the input. The IPO cycle is referred to as an information-processing computer procedure. In conclusion, it is an essential step in the calculation process that enables users to get the desired outcome.

Components of IPO

Three major components of IPO are - data input, processing operations and operating with output.

• Data input: During the input activity, data is entered or otherwise gathered electronically and converted into a form (machine language) that the computer can process.
• Processing Operation: The processing operation entails transforming or converting data so that it can be used as information. And the machine cycle, which describes how everything happens, mainly consists of four steps.
• Operation with an output: This operation creates information from data that has been processed in a way that others can use. Examples of output include printing text, graphs, and graphics from a computer screen.

Computer Elements - Input/Output/Processing/Storage Devices

A computer system's hardware consists of three basic components:

• The processing device is any hardware inside a computer that interprets and manipulates incoming data. The following are the system units (or processing devices): The CPU and memory are two critical components.
• Input/output devices: This category includes input devices that aid in data entry into the computer and output devices that display output to the user.

1. An input device is a computer device that helps users enter data into a system and send instructions to the required system, which then finally executes tasks. These devices are mostly hardware, such as keyboards, joysticks, and so on.
2. An output device is a computer device that displays the result of the CPU's processing of the inserted input data.

• A storage device is a hardware device that can be used to store digital data and applications in the form of images, video, audio, and so on. For example - External HDDs and SSDs, Flash memory devices, Optical Storage Devices, Floppy Disks, etc.

IPO Cycle - Key Points

Some key points on the IPO cycle are listed below-

• The three essential components are input, process, and output.
• Computer elements like input/output/processing devices have used the process.
• When a machine needs input, the user or any other source must feed the data into the device using keyboards and other means.
• The CPU is carrying out a calculation that the user has requested.
• The output is the information conveyed to the user via the display and complies with the specifications.
• Millions of users will cycle through this loop numerous times, producing the intended outcomes.
• Examples: After entering the values in the calculator, the results are displayed. A song or video that you download to your computer is an example of the output.
