Motherboard determine the type of the installed processor, amount of RAM and the number of peripherals that can be connected to a computer, that is, the possibility of further scaling the system. In addition, the motherboard is not the last to determine the performance of computers.

Modern motherboards have the following major components:

Motherboard determine the type of the installed processor, amount of RAM and the number of peripherals that can be connected to a computer

  1. connector for the CPU;
  2. slots for memory modules;
  3. chipset;
  4. AGP slot or a PCI-Express graphics card to be installed;
  5. PCI slots for peripherals;
  6. connectors for hard disk drive CD/DVD-ROM, mouse, keyboard, and so;
  7. The system chipset (chipset) to manage the exchange of data between all the components of a personal computer. The two main chip chipset called the "north bridge" and a "south bridge";

In the PCI slots are installed internal modems, sound cards, network cards, TV-tuners and other specific devices and adapters. Modern motherboards have from three to six such slots, not counting the AGP or PCI-Express slots for graphics cards.

Some motherboards have built-in graphics adapter. There are also board equipped with integrated graphics but allow the installation of a graphics card.

Powerful modern computer need a disk subsystem. Modern motherboards support ATA interface 100, ATA 133 and SATA. However, special advantages over the previously used the ATA interface 66, they do not provide, as far as the peak bus bandwidth that connects the hard drive to the computer. Physical data rate between the hard drive and its controller is much lower, so the transition to a high-speed interfaces are not really allows you to create much more efficient disk subsystem.

Many modern motherboards are equipped with an integrated sound card. Another possibility, which is supported by motherboards is the integrated network adapter. These motherboards should only be used when the computer is on a LAN, or to connect to the Internet.

Another functionality that is set by the manufacturer on the motherboards are USB-bus. Note that there are three USB-Standards: USB 1,1 and USB 2,0 and USB 3,0? differing primarily in transmission speed. USB 3,0 - the new, faster standard. All modern motherboards have at least two connectors for USB-devices.

Of course, the motherboards are determined, first of all, set them on the chipset, but also from the manufacturer depends very, very much. And the most important - is the stability of the work. Among the most popular manufacturers of motherboards are of the following companies: ASUS, Abit, AOpen, DFI, Gigabyte, Intel, Soyo, Epox, MSI.
