01 Mainboard core capability: Transmission link
< br >
This science popularization we do not talk about CPU, graphics card this popular hardware, but talk about the relatively unpopular motherboard, many cute new even do not know that there is such a thing in the computer, but in fact the motherboard is the computer in the most abundant electronic hardware, it is the carrier of all the computer hardware, composed of the computer's main circuit system and important driver chip original. The biggest role is as a hardware data interaction and power transmission link.

Motherboard as a carrier of computer hardware, theoretically as long as it can be physically compatible, that is, the use of low-end motherboard with high-end CPU, graphics card and other hardware pack, can also start to use normally, but such a combination of performance is not guaranteed, because the quality of the motherboard will also affect the performance of other hardware. We all know that the \"board\" of the motherboard is actually a circuit board, which will have different data interactions because of the choice of different inductors, resistors, chips and other components, as well as the wiring and insufficient.

High-end motherboard will select the original, and the layout of the cable, so that other hardware capabilities to give full play to, such as CPU, it is the most eat the power supply capacity of the motherboard, high-end motherboard power supply system can make high-end processor performance release, can be overclocked and other advanced speculation, and low-end motherboard power supply capacity is not good, light reduce processor performance, heavy blue screen of death, When the new crowd buys, we must pay attention to the collocation of the lower board U.

02 Expansion capability

In addition to data interaction, the motherboard is also the key to expanding the capabilities of the computer. We can see in the figure above, there are various types of slots on the motherboard, these slots are interfaces connected to the CPU, graphics card, memory and other hardware, and most of the time we can not use all of these slot interfaces, the remaining interface slots we can expand and upgrade.

For example, the above author marked the red slot, named PCIEx1 slot, this slot may not be used by most people, but it can actually expand the TV card, network card sound card and other hardware, each motherboard basically has a, high-end motherboard will even prepare more than 3-4, this expansion ability, is other hardware can not have, can allow users to more flexible control of their computer.

03 Auxiliary Maintenance
< br >
Because it can carry all the hardware, the motherboard is still our helper in the maintenance of the computer, the motherboard has a monitoring chip, can monitor the operation of the computer in real time, some high-end motherboards also have fault detection lights and even monitoring screens, even if they do not have external detection devices, to help you quickly find the computer problem.

In general, the motherboard as a carrier a platform, it will affect the play of all hardware, but also determine the performance of the whole machine, as the saying \"good U with a good board\" is also a word that everyone needs to remember.
Motherboard function:
1. Connect electrical appliances with different voltages together and provide the corresponding power supply.
2. Connect electrical appliances with different functions together so that they transmit information to each other.
3. Receive external data and give it to other devices for processing.
4. Centralize the data processed by the internal equipment and pass it to the outside world.
5. Balance data, energy, speed, temperature, current, etc., in the computer.
The motherboard, also known as the mainboard (mainboard), systemboard (systemboard), or motherboard (motherboard), is the most basic and one of the most important components of the computer. The main board is generally a rectangular circuit board, which is installed with the main circuit system of the computer, which generally has the BIOS chip, I\/O control chip, keyboard and panel control switch interface, indicator connector, expansion slot, DC power supply connector of the main board and card.
