Main Board

Motherboard (mainboard) is the circuit board where a variety of electronic components  connected to each other as micro processor and memory (RAM, ROM, BIOS)  together with other controller chip. The motherboard connects all the computer equipment and make it work together so that the computer running smoothly.
One form of the motherboard.

 Motherboard components
1. Power Supply
As the name implies, Power supply unit (PSU) serves to supply power to other components on the PC. All PC components (except power supply) will gain power from the power supply. Specifications that are listed
are the total maximum power and maximum power of each voltage (maximum current can be also). These values ​​should be observed. The common voltage supplied by power supply is +3.3 V, +5 V, +12 V,-5V,-12V, and +5 VSB (Standby).

 

First type of power supply that is often used is the AT models. In this model, we have to press the ON / OFF switch on the CPU if you want to turn off the computer. But this time, the type of power supply is ATX which is widely used because this model provides ease of turning off the CPU without having to press the ON / OFF switch on the CPU, simply by clicking on Shutdown.

Power connector on the Power Supply Unit (PSU)
Pin power connector that connects the motherboard to the power supply in case of a computer. In the AT type motherboard, casing is needed is the type of AT as well. AT type power connector consists of two parts, where the two wires from the power supply will be stuck there. In type ATX, power supply cables together in one header is intact, so you just drove it on the motherboard. This cable consists of two columns correspond to the pin on the motherboard that consists of two pin array as well. There are several types of motherboard provides two power connectors, AT and ATX. Most new motherboards have ATX type

2. Processor Socket or SlotThere are several types of plugs to plug in your processor. Model longest ZIF (Zero Insertion Force) Socket 7 or Socket 7 opular with the term. Socket is compatible to Intel-made processors, AMD, or Cyrix. Processor models are usually used for a long time (up to generation 233 MHz). There is another socket called Socket 370. Socket to Socket 7 is similar but the number of pins as the name suggests, 370 seeds. Socket is compatible with Intel-made processors. While AMD's own name with the term socket Socket A, where the pin is also different from the socket 370. A term used to designate the brand AMD Athlon processor. For Intel Pentium processor family II and III, which is used slot called Slot 1, while the motherboards that support AMD processors use a slot A to slot kind of like that.3. ChipsetThe main chipset on the mainboard there are two, namely the Northbridge and Southbridge. Northbridge is the bridging function of the flow of data around to play Memory, Processor, Front Side Bus AGP Busdan also set power management work. While the work function of Southbridge is set such peripheral peripheral-IDE Controller, PCI bus, BIOS ROM, Keyboard & Mouse, USB, Eth. LAN, Modem, and the function I / O other.4. Memory SocketAlso there are two types of memory sockets are now circulating on the computer. Indeed, there is also a new socket for Rambus DRAM, but until now there has been a lot of users who use it. Socket length is still quite popular is the SIMM. Socket pin consists of 72 modules. The second socket has 168 pin modules, which are designed in one direction. You can not put it upside down, because the strain on the motherboard has been adapted to the type of DIMM memory socket.5. Floppy and IDE connectorsThis connector connects the motherboard to save computer devices such as floppy disk or hard drive. IDE connector on a motherboard usually consists of two, one is the primary IDE and the other is the secondary IDE. Primary IDE connector connects the motherboard to drive primary master and secondary master device. Meanwhile, the secondary IDE connector is usually connected with CDROM pirantipiranti to such slave and the slave drive. How to connect a pin with cable? It was easy. IDE ribbon cable has a dash of red on one side. Strip the red mark, the red berstrip cable plugged in the pin number 1 on the connectors. When the stick upside down, the device will not be installedrecognized by the omputer. The same goes for the cable connecting the floppy with the pin on the motherboard.6. AGP slotThis image penyelerasi port slot graphics card supports 3.3V/1.5V AGP 4X mode for 3D graphics applications.7. PCI slotsPegembangan slot PCI 2.2 32-bit PCI bus master in9i mensopport cart cart like SCSI or LAN with a maximum output of 133MB / s.9. Parallel and Serial portsIn type AT, serial and parallel port not integrated in the motherboard but is connected via cable. Thus, the pin motherboard available for plugging in a cable. Bermacammacam parallel port functions, ranging from connecting a computer with printer, scanner, up to connect computers with peripheralsdesigned using a specific parallel port connection. Serial port is typically used to connect the cable modem or mouse. There are also other devices that can be plugged into the serial port. The type of ATX motherboard, parallel and serial ports are integrated in the motherboard, so you do not need to plug cables are troublesome.10. RJ-45 PortPort 25-pin connector connects the LAN through a central network.

At 6-channel mode, this jack funsi menjadai bass / mid.12. line out jackjack line out (lime) connects to headphones or speakers. At 6-channel mode, this function is a speaker jack out front.13. microphone jackmic jack (pink) is synchronize to the microphone. At 6-channel mode funsi rear speaker out jack is back.14. USB 2.0 port 1 and port 2The second USB port (universal serial bus) 4-pin is provided for connecting USB 2.0 devices.15. USB 2.0 port 3 and port 4kedu port USB (universal serial bus) 4-pin is provided for connecting USB 2.0 devices.16. Video Graphics Adapter Port15-pin port is for a VGA monitor or VGA-compatible devices17. Keyboard connectorThere are two types of connectors that connect the motherboard to the keyboard. One is a serial connector, while the other one is a PS / 2 connector. AT type serial connector or a round, larger than the model of the PS / 2 had, with a pin hole total of 5 pieces. Meanwhile, PS / 2 connector has a pin hole 6 pieces and smaller diameterthan half of AT models.18. CMOS batteryThis battery serves to provide power to the motherboard to recognize the installed configuration, when he did not / do not get power from the power supply.
