The term Components of Computer refers to the “Computer Hardware” or “Computer Software” or “Liveware” that can be touched or seen. After reading this article completely, you will get to know about the 7 major Components of Computer System.
Computer Hardware : It refers to the physical collection of computer parts. It includes both the internal and external parts of computer, such as Mouse, Keyboard, Monitor, Hard Disk , Video Card or Graphic Card, Motherboard etc.
Computer Software : It refers to the the coding/instructions/programs that tell Computer System How to Work. Computer software can be of three types :
• Programming Software
• System Software
• Application Software
The major Components of a Computer with the common objective are input unit, output unit, Internal Memory/RAM or ROM and CPU.
So, here we begin with the list of 7 Major Computer Components with their functions:
1. The Motherboard
Motherboard is simply a Circuit Board which is Printed that contains the principal components of the computer with connectors.
It allows to establish the communication between different Components of Computer System such as communication between Central Processing Unit – CPU and Memory. It also acts as a connector for other peripherals.
2. The CPU
CPU stands for Central Processing Unit .It is also known as main processor or central processor of the computer. It’s function is to carry out the instructions of the computer programs by performing the specified operations on the computer.
CPU’s are mostly made of Silicon. The program instructions are stored in that in form of binary codes.
3. The RAM
RAM refers to Random Access Memory . RAM is a type of Memory that can be read and written in any order to store binary machine codes. Because of the presence of RAM in the computer , We are able to find the Specific Informations Very quickly .
The Most Common Form of RAM used these Days is Dynamic RAM. The Computer uses the RAM to load Data Directly From a Hard Drive.
4. The Hard Drive
HDD (Hard Disk Drives) were introduced by IBM in 1956. The Hard Drive is in the shape of rectangular metal box with the width as like of a book.
A Hard Disk Drive is a device which stores data in electro -magnetic form and to re-collect or read digital information with the help of rigid rapidly rotating disks known as platters.
5. The Video Card or Graphics Card
It is a hardware that creates the images we see as display on a monitor. Video cards includes a processing unit,a memory, a cooling mechanism and few connections to a display device.
The Graphics Card are responsible for showing an image to our monitor, it does this by converting data into a signal that our monitors can understand easily.
6. The Power Supply
A Power Supply is a Device whoose function is to supply electric power to an electronic load.It is also called PSU ( Power Supply Unit) whose function is to supply power to the computer.
A PSU ( Power Supply Unit) converts AC ( Alternate Current) mains to the required low voltage DC ( Direct Current) power for the different components of the computer.
7. The Optical Drive
An ODD refers to Optical Disk Drive which uses electromagnetic waves and laser lights near the visible light spectrum in order to read or write data.
Optical Disks are used for the purposes of taking backups of small amount of data.They are important part of our PC as it enables us to read or write CD’s , DVDs and Blue Ray Disks.
Finally ,as a result of reading this article you are now known to all 7 major Computer Components (mentioned above) .
