Getting to Know the Main Components of the Computer and its Functions

Getting to Know the Main Components of a Computer and Its Functions this time I will discuss the article about “getting to know the Main Components of a Computer and its Functions” just let’s discuss it gusy so it’s not curious.

There are many components contained in a computer, do you know what components are included in the main components of a computer? And what function? To answer these questions, it is very important that you read this article.

Main Components of the Computer and Its Functions as Follows:

• Motherboard / Mainboard

The motherboard (often also called the mainboard) is a piece of computer hardware in the form of a board, where the motherboard hardware is the most important hardware and is very important because it contains the system BIOS

(Basic Input Output System), regulator of input-output connections (chipsets), memory sockets (RAM), graphics card sockets (VGA Card), processor sockets, and additional card sockets (additional cards such as PCI, ISA). Motherboard function is as the center of all computer hardware so that all computer hardware can be related to one component to another.

• Processor / CPU (Central processing unit)

Processor is a computer component that is the brain that runs the process and controls the work of the computer in collaboration with other computer devices, the speed unit in the Processor is Mhz (Mega Heartz) or Ghz (Giga Heartz) with the greater the processor speed, the faster the computer’s performance when run. The function of the Processor is to process data received from input or input, then it will produce output or output. How the processor works continue to be connected with other computer components, especially the hard drive (HDD) and RAM.

• RAM (Random Access Memory)

RAM (Random Access Memory) is a temporary storage area when the computer is running and can be accessed randomly or randomly. the program that we process for a while (power on) if our computer dies, then all data stored on RAM will be lost this memory is temporary storage and capacity is also not too large.

• VGA Card

VGA card (Video Graphics Accelerator) is a part of the computer, inside the CPU which is very important to display the process output to the monitor. Without a VGA card, the computer screen will not display anything alias blank. VGA card itself is in the form of an additional slot or motherboard manufacturer or also called VGA on board. The function of a VGA card is to process graphical data and display it on the monitor screen, VGA also has a processor called a GPU (Graphics Processing Unit).

• Hard disk drive

Hard disk drive abbreviated as HDD is a hardware component that stores secondary data and contains a magnetic disk. The function of the hard drive is to store data permanently, especially as an operating system storage and we can access it anytime we want. Its capacity is measured in Giga Bytes.

• Power Supply

In the form of a box whose contents are wires for channeling voltage into other hardware. The amount of electricity that can be handled by the power supply is determined by its power and is calculated in Watts. The function of the Power Supply is to supply the voltage directly into computer components such as hard drives, motherboards, DVD ROMs, fans and other computer components.

• Heatsink / Fan Processor

Heatsing is the act of reducing or eliminating heat from a computer. Heat on the computer has the potential to damage or slow down the work of a computer. The function of the Heatsink is as a processor cooler, if a processor does not have a fan then the computer will not work properly or other things that will happen the processor will die completely, because it is not strong enough to withstand heat.


CD-ROM is an acronym for “compact disc read-only memory” is a compact disc of the type of optical disc (optical disc) that can store data. CD-ROM also means that the CD-ROM drive can only be used for reading

just a CD. The function of a CD ROM is hardware that can only read CDs. in addition to these basic uses the CD ROM is also used to install an OS (Operating System), games, or other software. or boot when entering the OS.

• Casing

Casing is the inside of a computer that functions as a garment or protector from the CPU. A common shape is a square box. Function Casing is in addition to CPU protectors, the casing can also function as an additional cooler. because usually, modern today is equipped with a cooling fan whose number is more than one.

• Monitor

A monitor is a computer component that functions to display images that are output from a video card. Computer monitors that are widely available on the market today are CRT monitors (monitor tubes) and LCD monitors, but nowadays most people prefer to use LCD monitors (especially in offices) because these LCD monitors besides looks more modern, also have Another advantage is saving space and saving electricity.

• Keyboard

The keyboard is an input computer component that functions as a tool for typing things. In addition to the standard keyboard, computer keyboards currently have various models, such as mini keyboards, flexible keyboards that can be folded, wireless keyboards that use Bluetooth, and so forth.

• Mouse

Mouse is an input computer component that functions to move the cursor on our monitor screen and to click on something like buttons in an application program. The mouse is also various models, there is a standard mouse, mouse for gaming purposes, wireless mouse that uses Bluetooth, and so forth.

And that is all the Main Components of a Computer, and if you don’t understand, you can comment here, That’s all from me and hopefully useful.
