Computer Hardware

Computer Hardware is all the physical components that make up a computer, such as the CPU, RAM, motherboard, hard disk, and so on. Computer hardware is very important to the success of a computer because without hardware, a computer cannot function properly.


The CPU (Central Processing Unit) is the brain of the computer. The CPU is responsible for coordinating and executing the tasks assigned by the user. The faster the CPU, the faster the computer performance. CPUs are distinguishe by their speed and the number of cores they have.


(Random Access Memory) is a type of memory that can be accesse randomly by the CPU. RAM stores data that is ing processed and allows the CPU to access that data quickly. The greater the RAM capacity, the more data can be stored and accessed quickly.


The motherboard is the main circuit board that connects all of the computer’s hardware components. The motherboard has slots for the CPU, RAM, and expansion cards such as graphics and sound cards. Motherboards also have different types of connectors such as USB, Ethernet, and HDMI.

hard disk

The hard disk is the main storage device in the computer. The hard disk stores the operating system, programs and user data. Hard disks have different capacities, depending on the user’s needs. Hard disks are also distinguished by type, namely HDD (Hard Disk Drive) and SSD (Solid State Drive).

Graphics card

Graphics card or VGA (Video Graphics Adapter) is a device that produces images on the monitor screen. The graphics card has its own RAM which is use to store image data. Graphics cards come in different speeds and capacities.

Power supply

A power supply is a device that converts AC to DC electricity for use by computer hardware components. The power supply also provides power to the cooling fans and other devices inside the computer.

Cooling fan

Are use to keep the CPU and graphics card temperatures stable. Cooling fans can be attached directly to the CPU or graphics card or to the computer case.

Optical drives

An optical drive is a device use to read and write CDs, DVDs or Blu-rays. Optical drives are no longer commonly use because many computers no longer provide slots for optical drives.


The keyboard is an input device used to enter data into the computer. There are various types of keyboards such as mechanical keyboards, membrane keyboards and wireless keyboards.


The mouse is an input device used to control the pointer on the monitor screen. Mouse has various types such as optical mouse, laser mouse and wireless mouse.

Computer hardware is very important for optimal computer performance. Choosing the right hardware components can improve your computer’s performance. The better the quality of the hardware, the more stable it is
