The motherboard and its role in personal computers

One of the most important parts of your computer is the motherboard. However, its name speaks for itself. After all, it depends on it, what equipment you can install on your personal computer. The motherboard not only connects all other parts of the computer, but also coordinates their work and distributes the electricity that is fed to it from the power supply. Now a few words about what the motherboard consists of.

The first and most important component can definitely be called a chipset. It is a complex of microcircuits and determines the configuration of the computer as a whole. However, the chipset is present in any technique that uses electronics.

The chipset itself consists of the south and north bridges. The North Bridge is responsible for the operation of the processor, RAM and video card. For all other resources (hard disks, network card, USB ports, etc., etc.) is responsible for the south bridge. It directly depends on the chipset which processor the processor will be in, because if they are incompatible, the computer simply will not work. As a rule, the processor and chipset belonging to the same manufacturer firm are compatible, but there are relatively universal chipsets that can work with a large number of processors.

Thus, the technical parameters of the chipset affect the performance of the entire motherboard – performance, capacity and, accordingly, its price.

An equally important part of the motherboard is the RAM.

Over the years of the development of the computer industry, many different modifications of RAM have been replaced. Now in new assemblies use the DDR2 and DDR3 memory. To be more precise, either DDR2 or DDR3, depending on the configuration of the motherboard. At the same time they can not be used.

Do not forget about the video card. As the name implies, the video card is responsible for the quality of graphics on the computer. Therefore, users who need very good image quality (for example, those who professionally work with graphic editors or simply like beautiful computer games that require a good graphic resolution), often put themselves on the motherboard for another, an additional video card. Depending on the power, the video cards may differ in size.

This is due to the fact that large capacities require a more serious cooling system, so that the graphics card does not overheat. If you also want to put the second video card in the computer, first make sure that it fits your motherboard by its configuration and size (sometimes the video card slots are quite close to each other and the second card may not fit). There are also motherboards with an integrated (built-in) graphics card.

Sound and network cards are usually built-in motherboards originally. However, if they are not available or if you need to install a more powerful card, you can purchase them separately. Of course, guided by the configuration of the motherboard. These cards are responsible, respectively, for the reproduction of sound and for the operation of the computer with the network (access to the Internet, connection to other computers).

The dimensions and location of the various ports describes the form factor. This is the name of the standard, which gives an idea of ​​the spatial configuration of equipment. The standard is recommendatory in nature, however, most companies try to follow it when assembling, as it represents the optimal solutions for the configuration of equipment. Thus, each form of the mother card must have a certain form-factor of the computer case, and this must also be taken into account.

And finally, be sure to pay attention to the socket. A socket is a socket for connecting a processor. The connection occurs by inserting the socket feet into the holes on the processor. The number of legs and the size of the sockets of different models differ. Of course, certain models of sockets can serve to work with a limited number of kinds of processors.

In other words, if the processor to the socket does not fit, then you simply can not put it there, since the position of the legs will not correspond to the position of the holes on the processor. As an example, we can say that Intel processors work with LGA-type sockets (LGA1155, LGA1156, LGA1366, LGA775), and AMD processors, respectively, with AM (Socket AM3, Socket AM2 +) models.

Finally, I want to add that there are a lot of different configurations of motherboards. Their production is engaged in such brands as Intel, Gigabyte, Asus, Foxconn, MSI, Biostar. You do not have to single out any of them, they are all good in their own way. Because everyone chooses the computer (and accordingly, the motherboard) specifically for their needs. A properly selected motherboard will provide your computer with a long and reliable operation.
