What the motherboard does: 1. Connect electrical appliances of
different voltages together and provide the corresponding power
supply. 2. Connect electrical appliances of different functions
together so that they transmit information to each other. 3.
Receive external data, and to other equipment processing.
The internal device processing data set, and pass to the outside
world. 5. Balance data, energy, speed, temperature, current, etc.
in a computer. Extended data working principle: below the board,
there are 4 layers of circuit wiring; above, the division of labor
is clear for the various components: slots, chips, resistors,
capacitors and so on. When the mainframe is powered on, the current
will pass through the CPU, north-south bridge chip, memory slot,
AGP slot, PCI Slot, IDE port, serial port port, parallel port, PS 2
port and so on. Subsequently, the motherboard will be based on the
BIOS (basic input and output system) to identify the hardware, and
enter the operating system to play a support system platform
functions. Main type AT: Standard Size Motherboard, IBM PC a
machine first use named, some 486,586 motherboard also uses AT
structure layout. Baby AT: small size motherboard, smaller than AT
Motherboard, hence the name. Many of the original machines
integrated motherboard first used this motherboard structure. ATX:
Improved AT Motherboard, the motherboard components have been
optimized layout, better heat dissipation and integration, the need
for special ATX chassis use. BTX: an improved version of the ATX
motherboard, it uses a Low-profile design to make the component
layouts more compact. In view of the movement characteristics of
air flow inside and outside the chassis, the main board engineers
have optimized the layout of the main board, making the computers
heat dissipation performance and efficiency higher, the noise
lower, the main board installation and disassembly become more
convenient.
