How Computer Hardware Actually Works: With the development of computer technology today, we have listed what the components actually do, which we hear almost every day.
Computers have been accompanying us in many areas of our lives since the 1940s. Computers, which we have encountered in different shapes and sizes until today, are now in all areas of our lives. Most of you have heard of computer components such as processors, motherboards and graphics cards before. Especially users who buy computer parts themselves and create their own computers can learn about the above components. But do we know enough about these computer parts that we are so intimate with? Let’s look for the answer to this question below.
Computers, as the name suggests, are electronic machines that process information. It takes raw information or data, stores it until it is ready to run, and then outputs it to the user.

How Computer Hardware Actually Works?
All the complex operations we do on a computer are made up of these four operations:
- Entry: Each unit that introduces data to your computer is an input unit. This input unit can be a keyboard, mouse, headset or gamepad.
- Memory: Your computer collects all your documents and files on a hard drive.
- Processing: All the actions your computer’s processor takes to reflect input as output is called processing. The processor is one of the most important and at the same time the smallest components of your computer.
- Output: It means that an action you take in the entrance units will come across. This could be a video you open using your mouse or a piece of paper coming out of your printer.
Components that keep the computer running
- Processor (CPU)
- Hard Disk (HDD)
- Graphics Card
- Power Supply
Computer central processing unit: Processor (CPU)
The computer does its primary job in a part of the machine that we cannot see, in a control center that converts data entry into information output. Called the central processing unit (CPU), this control center is referred to as a highly complex, comprehensive set of electronic circuits that execute stored program instructions. All computers, large and small, must have a central processing unit.
Computers use two types of storage: primary storage and secondary storage. The CPU closely interacts with primary storage or main memory, referring to it for both instructions and data. Therefore, this part of the reading memory can be counted in the context of the central processing unit. Technically, however, memory is not part of the CPU.

There is of course a reason why the Central Processing Unit (CPU) is considered the most important component in a computer. The CPU performs most of the functions that fulfill its function by processing instructions and sending signals to other components. The CPU acts as the main bridge between all the main parts of the computer. Keep reading to find out how computer hardware actually works?
Temporary storage space: RAM
RAM is a high-speed storage component that our computers and applications use to store and access their temporary data. It can also be called the short-term memory of the computer. Instead of storing data in storage areas such as HDD or SSD, it works by storing common data that programs constantly use.
In short, RAM is a computer component where the data used by the operating system and software applications stores data so that the CPU can process this data quickly. Unlike HDD and SSD, everything stored in RAM is lost when the computer is shut down. Depending on the applications you use, the RAM storage you will usually need for the computer to function properly varies from person to person. If you are an average computer user, 8 GB can be enough, while you may need 16 GB of RAM if you play high-graphic games or use heavy productivity programs.

Data is stored and protected: HDD
HDD, also known as Hard Disk Drive, is the component where photos, applications, documents, games and such data are stored. Although HDDs are still in use, computer users today predominantly use SSD, a faster storage medium. Keep reading to find out how computer hardware actually works?
HDDs store data through magnetism. The fact that every field of the shiny, circular plate made of a magnetic material is magnetizable is used in computer storage. Because magnetism continues to store information even when the computer is turned off, unlike RAM. Likewise, storage on your devices other than your computer mainly works in this way.

Motherboard, which is the main component of the computer
As the name suggests, the motherboard is the main component of the computer. With a slot for all components, the motherboard allows these components to communicate with each other. It also distributes power to the motherboard so that all components can function. The motherboard, which does not work on its own, is an essential part for the computer to work.
The task of the motherboard is to house the microprocessor chip of the computer and allow every other component to be connected to it. Anything that powers the computer or improves its performance is either part of the motherboard or is attached to the motherboard via a slot. Motherboards come in different sizes to fit in different sized cases. The motherboard compatibility of all purchased components should be checked to improve the performance and speed of the computer.
Graphics Card that provides 2D and 3D outputs to the monitor
Working with software applications, the CPU sends information about the image to the graphics card. The graphics card decides how the pixels on the screen will be used to render the image of the processed data. It then sends this data to the monitor via the cable.

Graphics cards that can create 2D and 3D visuals put a little more effort into 3D visuals. In order to create a 3-dimensional image, the graphics card first creates a frame from straight lines. It then rasterizes the image (fills the remaining pixels). It also adds lighting, texture, and color. In order for computer games to be fluently reflected on the monitor, it needs to perform this process approximately 60 times a second. Without a graphics card to do all these calculations, it would be quite difficult for the processor alone to cope with such a workload. Keep reading to find out how computer hardware actually works?
Power Supply that keeps the electric current constant
Power Supply is the backbone of the computer’s electronic system. The power source that supplies the electrical current to the system should be selected according to the components used and the electrical status of the building. Voltage level fluctuations do not damage the components of your computer thanks to the power supply. Power regulation functionality added to power supplies increases the cost of the resource but can also save the user from the trouble of purchasing new components.
