2. computer construction - processor cooling system, as support for the most important component


Among the important parts of the computer also includes the processor cooling system. This component prevents it from overheating - thus protecting the entire computer from performance degradation and damage that can occur due to excessive temperature increases inside the entire system.


There are several types of CPU cooling systems. The most common are those cooling with air or liquid. They differ, among other things, in the way they are maintained, but also in the mode of operation - those based on an air system generally generate more noise, so for some users they are non-functional.


3. motherboard


What else it contains computer? Construction of the device is designed to accommodate the motherboard as well, since without this element it will not be possible to start the computer and use it. All components are installed on the board. These include:

  • graphics card,
  • processor,
  • RAM.

The board connects the components together and allows them to communicate with each other.


Keep in mind that it is the motherboard that determines how you use your computer. Its parameters determine what you can connect to it and how you can use the whole device. Therefore, it is worth remembering to be guided by practical considerations and possibilities regarding technological developments when choosing this component.


Changing needs require replacing components such as the graphics card to take advantage of all the possibilities offered on the market in this regard. When buying a motherboard, make sure that it provides expandability. In this way you will gain confidence that it will be tailored to the changes that are most likely to await you as technology evolves.


4. RAM in computer construction


What is a computer made of? Another important module is RAM, or primary memory. It is used to store temporary data, and thus has a direct impact on the functioning of the computer. It allows you to use various types of programs, play games, work in word processors and much more.


The amount of memory is crucial to the performance of the device, so pay attention to this aspect when choosing a computer for yourself. The more RAM, the better, because the computer is able to handle more applications at the same time and face more demanding tasks, such as video editing or playing games.


5. components in the computer - graphics card


What is in a computer component that makes it possible to display images on a monitor? It is a graphics card that renders images. This component can be integrated into the motherboard, but it can also be a separate component. There are several types of graphics cards. There are integrated chips and dedicated components. The former have a compact design, so they are most often used in laptops. The latter, on the other hand, provide high performance and are generally used in devices for demanding users.


When choosing a graphics card for your computer, first of all, analyze your own needs. If you use the device for work or study, this module is not so important to you. If, on the other hand, you are into video editing, photo processing or are a game enthusiast, a good quality graphics card will be crucial for the use of your computer, as well as the quality of your work with it.


Remember that the graphics card and every other component in your computer need good quality software to work properly. In the Key-Soft store you will find a wide selection of Windows - including Windows 10 and Windows 11, so you can match a specific option to your needs to enjoy maximum comfort while working, studying or relaxing.

6. hard drive


Key components in a computer is not only the processor or graphics card. It's also the hard drive, a storage device responsible for storing data. This component consists of platters on which information is stored. On the hard drive are stored, among other things:

  • operating system (e.g. Windows 10),
  • programs installed on the computer (including, but not limited to, antivirus, photo editing and video editing programs),
  • User files (photos, audio files and others).

This component comes in many different capacities. It also has a specific rotational speed, which directly affects the rate at which the computer reads and writes data. Devices available on the market today also differ in terms of interface (components that affect maximum data throughput) and application (individual drives are created for desktop or laptop computers, among others).


7. power supply - an important part for a computer


What is inside the computer And makes its operation possible? It is the power supply unit. This seemingly small part plays a very important role in the construction of the device. It is responsible for using energy from the electrical grid and converting it into the voltage that is necessary to power each of the components in the system.


The power supply consists of the following components:

  • transformer - converts the mains voltage to a lower one, adapting its parameters to the computer mode,
  • Rectifier bridge - converts alternating current into direct current,
  • filter - removes interference that may adversely affect the operation of the component,
  • Voltage regulator - keeps the output voltage constant.

Modern power supplies operate on the basis of technologies that allow to reduce energy losses and provide a higher level of energy efficiency. When buying this component for your computer, pay attention to such parameters as, among others, the power of the power supply (it should be matched to the specific device that the power supply is to support), the type of outlet and safety parameters. This way you will choose a model that will ensure safe operation of the entire computer.


8. computer case


The computer case is one of its most characteristic elements. It constitutes a "box" that covers all the modules of the device - it protects them, first of all, from mechanical damage. At the same time, it provides adequate ventilation and cooling, thanks to the holes located throughout the structure and appropriately arranged.


The component is also built in such a way that it simultaneously provides effective protection and gives constant access to individual components. This is necessary, among other things, in connection with ongoing maintenance of the device and the need for replacements or repairs.


The housing can be made of different types of materials. The most common is steel or aluminum. They can be dyed in different colors and formed in different ways - this allows manufacturers to achieve an interesting design of the structure, which can look, for example, minimalist and elegant, modern or youthful.


Each of the modules found in a computer is part of a whole, which gives the user numerous possibilities. Therefore, it is important to select individual components and combine them in such a way that the built computer is efficient and tailored to the individual needs of the owner.


Components and accessories for your computer - what is important?


In the context of the device itself, it is not only important, what components the computer consists of. Also important are additional components and accessories that affect the comfort of working with the equipment in question. These include, among others:

  • sound card,
  • network card,
  • camera,
  • microphone,
  • external USB drive,
  • Mouse,
  • keyboard.

Each of the aforementioned components affects the comfort of the user of a particular device. Therefore, it is also relevant in the context of discussing the construction of a computer.


What to look for when choosing a computer?


When choosing a computer for yourself, the modules and accessories that go with it, remember first of all to analyze your individual needs. Think about how you use the device most often, which elements you care about, and which are of least importance. In this way you will avoid buying all the equipment or individual components of the installation with too weak or too efficient technical parameters (the latter can be an unnecessarily large expense).
