Going into a computer hardware store is not difficultpay attention to the large rectangular boxes behind the glass on the windows. As a rule, the name of the manufacturer’s company (Asus, Gigabyte, Intel), the internal designation and a variety of supported functions presented in advertising style are usually written in them in large letters. Inside the boxes are motherboards (mainboards). They are used in computing systems, starting from the time of the first computers.
Despite this, users often ask a question."What is a motherboard". You can, of course, immediately give a definition, but life every minute confirms that any memorization without understanding is useless. Therefore, let's define what a motherboard is by conducting a small thought experiment.
As is known, the composition of any modernComputer includes, at a minimum, the central processor, video card, RAM. In order for them to work, it is necessary to provide power and connect all the conductors. Of course, this is very simplistic, but this is the basis. The solution to this problem is entrusted to the mainboard.
To see it in the computer, you need to remove the coversystem block case and look inside. Absolutely all the components are connected to the largest motherboard, which occupies the largest part of the case. Now computer owners who are interested in what a motherboard is and read this article will be able to distinguish it from other components. This is nothing complicated, as can be seen, if you know the characteristics.
So, the motherboard is the largest one.computer, which includes all other components. Without it, a computer cannot be assembled. You can work without an audio adapter, network chip, hard drive, and even without a keyboard, but never - without a mainboard. Interestingly, this English word translates as “main board”. More precisely there is no place.
To understand the device of the motherboard mucheasier if familiar with the basics of production. First, the future components are prepared - these can be connectors for peripheral devices, codec chips, the necessary chipsets and associated strapping elements (transistors, capacitors, power switches).
Next action on computerizedthe conveyor belt creates a procurement board. To do this, take a sheet of PCB (dielectric material) and in accordance with the map of the future placement of the elements are drilled holes. Then from two sides conductive paths are applied by an electrochemical method. The received preparation becomes covered by a varnish (except places of the soldering). Then a second sheet is created, etc. Although the holes in them are the same, the tracks are arranged differently. The last action all sheets are glued together into a single, receiving a multilayer structure. After that, the required elements (connectors, microcircuits) are soldered to the provided places.
The boards differ from one another.supported processors and the number of implemented functions. Of course, the layout of the components of the models is also different. To find the best, you need to be well aware of what a motherboard is and what features you would like to see in it.
In some specific computingdevices may be partially or completely missing connectors for external components (processor, memory, video). In this case, they are soldered to the board at the production stage, like ordinary chips.
In light of the above, it is easy to imagineWhat a danger to the motherboard is a system builder, inserting a video adapter or memory modules into the connectors with such force that the mainboard bends. If you see this, then you shouldn’t acquire a computer assembled in this way, because of the multi-layered structure, possible damage can be invisible and not immediately manifest.
