What are the Processing Devices of Computer System?


The computer system consists of hardware devices and some of these devices are also considered as processing devices. Do you want to know what are the processing devices of computer system with their types, definition, examples uses and function with pictures.

The processing devices are essential devices of computer systems that are responsible for processing and handling instructions and tasks given to them.

The computer system mainly consists of three types that are central processing unit (CPU), input devices, and output devices.

The CPU is further categorized into ALU (Arithmetic Logic Unit) and Control Unit (CU).

The computer system receives its data, instructions, and information from input devices, like the keyboard, these raw data are further processed with the help of the CPU to obtain desired result and output.

The output devices of computer systems are responsible to provide human-readable output to the users, examples of output devices are monitors and printers.

There are some storage devices in the computer systems that are designed and developed for storing data and information temporarily as well as permanently.

What are the Processing Devices of Computer System?

It is an essential device that every computer user must know about computer devices and storage devices with their purpose. 

There are two main types of computer hardware devices, external hardware devices, and internal hardware devices. 

External hardware is external hardware used outside of the computer, and internal hardware is internal hardware used within the computer. 

The keyboard and mouse are input devices through which we give commands to the computer.

Examples are opening any software and running it or creating any file with a given command. 

All of this process requires processing that is done by the computer. 

The CPU (Central Processing Unit) is known as the "brain" or “heart” of the computer system. 

The CPU is installed inside the computer in fact on the motherboard.

Our computer processor performs trillions of calculations per second, which is amazing speed!!!.  

The task and operations that are performed on the computer system are done through and with the help and assistant of the processor.

The computer processor is aware of all the operations and activities happening inside the computer system.

There is a graphics processor in a computer, also known as a graphics card, which processes the graphics in the computer. 

The images, pictures, and graphics are more clearer when graphics cards are used these graphic cards allow users to view the graphics on the screen with more clarity.

Users who use heavy graphics for processes, such as video editing, PC gaming, and professional video editing, need a GPU because they cannot use the onboard graphics of the computer, even with a GPU that delivers good picture and video quality. 

The video card is like the graphics card, but it’s smaller incapacity. 

The graphic card was used in earlier computers built in the motherboard. You can call it a small part of the GPU and it works very slowly. 

This is an important part of the computer device as it connects with every other essential component. The sound card helps us to play sounds on the computer. 

The sound is stored in binary code, so before we can play this sound.

Sound cards can be found on laptops, mobile phones, and speakers.

Different Types of Processing Devices in Computer System

Types of Processing Devices
Types of Processing Devices
  • Processor/CPU: Processor is an acronym for Central Processing Unit (CPU). The CPU is the computer’s brain and is situated on the motherboard. We use the computer to calculate the trial of anything we do in the computer, which is known to the computer because the processing does anything we do in the computer. The computer receives the command from the program files when we choose an icon from the software and give it. Later, the computer opens the program and displays the output on the output device, such as the monitor.
  • GPU: GPU (Graphics Processing Unit), known as Graphics card, is used for processing good videos and pictures, but it is not the main component of the computer since the computer uses onboard graphics connected to the motherboard and are what control the standard graphics. A person who plays video games and creates high-quality videos with that device is likely to need a GPU to process the heavy graphics in the game and the high-quality videos, so they need a GPU to do it.
  • Video Card: A video card is similar to a graphic card, but it has a lower processing power than a graphic card; video cards are built directly into computers’ motherboards; so it’s like a small part of the GPU that works slowly.
  • Motherboard: This is an essential device of the computer; with the help of this device, all other devices are connected to the laptop or desktop computer.
  • Sound Card: With the help of this card, we can play any sound saved in our device. The computer is able to save all types of sound binary code language for decode this; there is a sound card available in laptop, mobile, speaker.

List of Processing Devices and Uses

#Processing DevicesUses
1CPU (Central Processing Unit)It is responsible for every operation performed in the computer system.
2MotherboardThe motherboard is a piece of PCB {Printed Circuit Board} used to connect all other components through it.
3GPU (Graphics Processing Unit)They are used in processing high-quality images and videos.
4Video CardIt is similar to GPU but has considerably less processing power to produce images and videos.
5Sound CardIt is used to play sound.

Processing Devices 10 Example

CPU:  Central Processing Device receives all the instruction and data from the computer and presents output to users.
GPU: GPU is used to view video and pictures on the computer system with good quality. It handles all the graphics data of the computer.
Motherboard: it is the biggest board of the computer; it communicates between CPU, RAM and the devices.
Network Card: this is the expansion card for connection of the internet.
Sound Card: The sound card helps the computer listen to the songs stored in the computing device situated in the motherboard. 
Video Card: With the help of a video card, it is used to create a display on the computer and is also situated on the motherboard. 
RAM: It is a Random access memory which is a temporary memory that carries out instructions and operations given to computer system.

The Function of Processing Devices

Processors control everything we do on the computer; if you want to open software, you need processing;

if you’re going to watch audio or video, then you need processing, the processing is the input, and the output is what we see, the best example of this is CPU.

What are 7 Examples of Storage Devices?

There are different types of processing devices in computers that are very essential for the computer system’s functionality and usability.

Hard disk: A storage device used to store computer data like software, files, and songs.
SSD (Solid-State Drive): It stores more data; its storage capacity is about in Gigabyte.
RAM: It is a primary memory we work simultaneously, and we often see and write data.
ROM: It is read-only memory; we did not write it, and it only stores software.
Flash Memory: It is a different storage device used to connect to the computer. We store a large amount of data in the example of this flash memory card, a camera memory card.
CD Drive: It is also called compact disk, a circle shape. It is used to store data from optical rays.
DVD Drive: It is called a Digital video display; it stores maximum data of three types: read-only memory, recordable, rewriteable.
