Hitachi screw water chiller I/O motherboard C0972 parts cold water machineG7B00100A
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.
