Computer Processing and Processing Devices

A computer is an electronic device which processes the raw data given by the user and outputs the information. Data is input into the computer, and after processing, it is converted into the output or the final information. The processing of this data is done using various processing devices like CPU (Central Processing Unit), GPU (Graphics Processing Unit), MotherBoard, Microprocessor, Sound Card, and Network Card.

What is IPO Cycle?

The full form of the IPO cycle is the Input-Processing-Output Cycle. In an IPO Cycle, data is imputed to the computers as input, the processing devices process the data, and the output is produced.

We can learn this using a simple example of a mango shake. In this, mango and milk are taken as input and processed in a mixer, and a mango shake is obtained as an output.  This completes one IPO Cycle.

The IPO Cycle is the series of events which allow the computer to perform its work.

Computer Processing and Processing Devices

The processing devices are the computer hardware components that help to handle the processing of the information, storage and retrieval process of the information. In computers, processing devices play a key role in the processing of information with the help of programs. Processing devices process all the data imputed by input devices like keyboard, mouse, and trackball and the converted output information is transmitted to the output devices like monitor, speaker, printer, etc.

There are certain processing devices like-

• CPU (Central Processing Unit)

• GPU (Graphic Processing Unit)

• Motherboard

• Sound Card

• Network Card

• Microprocessor

CPU (Central Processing Unit)

CPU is known as the brain of the computers and is the primary component of the computers which enables the computer to perform all types of processing operations and all the operations of the components of the computer.

CPU

GPU (Graphic Processing Unit)

A GPU is a computer-integrated chip which helps the computer to render graphics and images by performing very fast mathematical calculations. It can be used for both personal and professional computing necessities. GPU can render 2D and 3D images, videos and animations.

GPU

Motherboard

The main circuit system of the computer is known as a motherboard. It is the main board of the computer. It is also called the logic board of computers. The motherboard consists of chips, and a controller is known as the chipset.

Motherboard

Sound Card

A Sound Card is a type of hardware installed on the motherboards and enables the computers to deliver the audio input and output facilities. Nowadays, these sound cards are in-built into the motherboards.

Sound Card

Microprocessor

A microprocessor is known as the heart of the computer system.  A microprocessor is a single integrated circuit inside the computer. All the arithmetic and logical functions are performed by the microprocessors.

Microprocessor

Network Card

A Network Card is also a type of hardware embedded on the motherboard which enables the computers to connect to the computer network, usually with LAN. Most of the motherboards nowadays have already embedded network cards in them, like sound cards. The network card helps the computer exchange data using a network.

Network Card

Points to Remember 

• The microprocessor is known as the “Heart” of the computer.

• Processing devices process information input by the input devices.

• The processed information is transferred to the output devices like monitor, speaker etc.

• Sound cards enable audio’s input and output capabilities in a computer.

• Network Card helps in connecting a computer to a computer network.

Learning By Doing

4. Keyboard

Ans: D)

2. Expand IPO Cycle.

Ans: Input-Processing-Output Cycle

3. What are the steps in an IPO Cycle?

Ans: The steps include:

• Firstly, the data is entered into a computer using various input devices like a keyboard, mouse, trackball etc.

• Then, the data is processed by the processing devices like CPU and GPU microprocessors.

• Then, the raw data is converted into useful information and is transferred to output devices like monitors or printers etc.

Summary

In this, we learnt what do you understand by IPO cycle and the full form of IPO and also learnt about the computer processing and processing devices. We learnt how different processing devices process different types of information and work together to make the user experience wholesome and provide the user with all the basic facilities in a single computer. We also learnt about various processing devices like network cards, microprocessors, sound cards, GPU, CPU, etc.
