For most users, such computers will fully satisfy their requirements. But for "advanced" users who want to squeeze out of the "typewriter" maximum, such computers are not the best option. They will prefer to assemble it on their own. It's also worth remembering that to manually build a computer, you need to know exactly what and where to insert, or you can refer to those who have this experience. Qualitative manual assembly leaves far behind the computers, staffed at the factory, and also costs less. But no matter which assembly you prefer, when choosing a computer, you need to pay attention to such components as: processor, motherboard, RAM, power supply, hard drive and video card.
Processor( CPU)
The processor is the "brain" of the computer. It is he who produces all the basic calculations and operations. At the moment, Intel and AMD are leaders in the processor market. The performance of programs and games running on the computer depends directly on the processor installed in the computer. Of course, a simple, low-cost processor( for example, AMD A10) will be enough for work. But for fans of modern games you need a powerful, high-frequency "percent"( for example, Intel Core i5 or i7).In general, the power and speed of the processor are measured in frequency units - hertz. The higher the frequency of the processor, the better, the same applies to the number of cores.
Motherboard
Motherboard( in the people simply "motherboard") - the basis of the whole computer. It looks like a huge board, with a bunch of connectors and slots. Serves it as a "support" for all components, and also connects them with each other. When buying an already equipped computer, the choice of motherboard is not so significant. And for those who decided to collect everything manually, it is worth paying attention to the connector for the processor, as the processors from Intel and AMD have different fastening systems. Also, pay attention to the number of connectors for RAM, video cards and the kinds of connectors on the rear panel: the more powerful you need a computer, the more they should be.
RAM( RAM)
RAM is the best companion of the processor. This is the amount of memory that the processor uses in its work. Powerful processor with high frequency + large RAM = fast and powerful computer. From this formula, we can conclude that the more memory to add to the processor, the better. But do not overdo it, excessive memory is an extra waste of money.
The optimal amount of RAM is 2 gigabytes. For gaming computers, it is desirable to have 4 gigabytes in stock. Also, if in time you want to improve the speed of your computer, you can add additional memory cards to additional slots on the motherboard. Also, do not forget that you need to add them in accordance with the "motherboard".Ask vendors or look at the instructions for the types of memory supported, and then select the card itself.
Power Supply
A computer without electricity is the same as scores without knuckles. The power supply unit supplies all components of the computer with electricity. Power supply power affects the stability of all parts of the computer. Gaming computers consume a lot of energy, which in turn makes it impossible to use weak power supplies. For such computers, blocks of 1000 watts are required. It is also worth paying attention to the presence of a fan in the power supply, since without proper cooling, you can only achieve damage to the "innards" of the computer. For a simple computer, the power supply must have at least 500 watts of power.
Hard disk
Hard disk is a device that remembers and carefully stores all the information that we have on the computer. Operation system, documents, music or movies - all this is stored on the hard drive. For storing music and documents, a hard disk with a capacity of more than 200 gigabytes is enough. And for fans of games and films in Blue-ray, the volume in 500-1500 gigabytes is perfect. In any case, the amount of physical memory can be expanded with an external hard disk.
Video card
Video card - an important component for any gamer and moviegoer. Without it, the image will not be displayed on the screen of the monitor, and if its parameters are weak - watching movies in HD-quality and games with powerful graphics will slow down. The memory capacity of the video card affects the quality of the graphics played in the games. In general, the performance of a computer in games depends not only on video memory, but also on RAM and processor power. The cooling of the video card is of great importance, since its overheating will lower the quality of the work and can damage the card itself. Preference is given to cards that are equipped with fans. The cards, equipped with radiator cooling, do not shine with a special performance. If you do not need a powerful computer, then you can choose the architecture of a computer with an integrated graphics card( based on an AMD processor with a supported motherboard).
Another important aspect is the body, but here's an amateur. Also, the computer includes a CD / DVD-RW drive and a card reader, but if the first is required, then the second one is optional.
In general, the choice of the computer depends on your preferences. And do not forget that a quality computer chosen in the future can save you time, nerves and money!
In our time, the computer is no longer a luxury, but a means of interacting with the world around us. The computer is a huge leap in the development of civilization. With its advent, various areas of the industry related to digital and information technologies began to actively develop. Now the computer is used in almost all spheres of human activity: it makes us boring work for us, connects people who live on different continents and simply helps to relax and have fun.
