MOTHERBOARD

Circuit Of Motherboard

What is Motherboard ?

Motherboard is the main Board, or circuit board that serves to connect

each component on your computer. Motherboard PCB Board that has a systematic

line that connects one component with the other components. The Motherboard

could be called also the Mainboard. On the mainboard there is a parts input as

well as output either a socket or a slot. Like socket processor, memory slot, USB

connector, power supply socket, peripheral Slots, i/o ports, etc. So all over the

place for components are neatly arranged in this motherboard. The Motherboard is

stored or placed in a Casing (Computer Box). So all existing components in

computer connected in circuit board called the motherboard.

What Are The Devices Are Needed In Motherboard

Chipset

This Chipset is a small-sized IC be traffic data or otherwise directing the

flow of data. The Chipset has an influence in maximizing the performance

of your computer.

Useful Power connectors

To connect the motherboard to the power supply in the casing of a

computer. Through this connector motherboard Gets a flow of electricity.

Battery CMOS

The CMOS battery (also called CMOS RAM or just the CMOS) is a

battery that is used by the BIOS to remain active even without the flow of

electricity. One of its uses to enable and run the function, as well as saving

the settings BIOS, and generally put the battery button (the round flat

Battery, diameter and thickness varies).

Processor Socket or Slot

Used for putting processors. Socket or slot is different, depending on the

type of motherboard is used. Anyone have a slot, socket, and there's also

that has both a function to multiple processors.

Memory Slot

Where to put the RAM or memory. Usually we have to look at the specs of

the chipset on the motherboard to find out the type of a memoryi can be

fitted. There is a memory type SDRAM, DDR or RDRAM.

Floppy And Ide Connector

This connector connects the motherboard to save computer devices such as

a floppy disk or hard drive. The IDEA of a motherboard connector usually

consist of two, one is primary IDE and the other is the secondary IDE.

Primary IDE connector connects the motherboard to the primary master

drive and other secondary master. Meanwhile, the secondary IDE

connector is usually connected with hardware devices to slave as slave

disk and CDROM.

PCI Slot (Perpheral Component Interconect)

PCL uses slot is to add additional devices to the motherboard is typically

used to add a VGA Card, Sound Card and Modem.

AGP Slot (Accelerated Graphic Port)

A slot port support card graphic fashion 3.3v / 1.5v agp 4x for application

graphic 3d.

South bridge controller

Serves to connect the input, and controls output between, processor, ram, a

storage device and peripheral other.

Standby Power LED

This lamp on standby in motherboard if there ' s power.This led act as

reminder ( a reminder ) to turn off system power before turning or killed

the engine.

Serial and Paraller Port

On the type AT, serial port and parallel are not fused in one motherboard

but connect via cable. So, on the motherboard available pins for plug

wires. The various parallel port functions, ranging from connecting a

computer with a printer, a scanner, to connect a computer with a specific

peripheral is designed using the parallel port connection. Serial ports are

usually used to connect with a cable modem or mouse. There are also

other devices that can be plugged into the serial port. In the motherboard

type ATX, parallel and serial ports are already integrated in the

motherboard, so you don't need to plug in the cables that are troublesome.

RJ-45 Port

Port 25-pin connector connects a LAN through a network.

Line in jack

Jacks line in (light blue) corresponds to a tape player or other audio

source. On a 6-channel mode, this jack the bass/Middle stepped.

Line Out Jack

jack line out (lime) it connects to the headphone or speaker. On a 6-

channel mode, the jack into the speaker out front.

Microphone jack

Jack mic (pink) is unpaved roads to the microphone. On a 6-channel mode

the rear speaker out jack's back.

Video Graphics Adapter Port

15-pin Port is for VGA VGA monitor or other compatible device

Keyboard Connector

There 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. Serial connector or round shaped type AT, larger than the PS/2

model had a pin hole, with 5 pieces. Meanwhile, the PS/2 connectors have

holes of pin 6 fruit and smaller diameter than half the models AT.

PS/2 Mouse Port

To plug the PS/2 type Mouse

USB Port

To connect a variety of devices that use USB as Pendrive, USB Mouse and

Keyboard, and others.

What are the Function Of Motherboard

The functions of the motherboard itself is a place for connecting devices-

computer hardware in order to be able to connect to each other so that the

computer can work smoothly and optimally.

What Is The Principle Work Of Motherboard

Motherboard Motherboard power supply gets from a power supply, the

voltage of which will be channeled through a power connector. The entire

peripheral installed damper with power supply will get a MB. After getting

the supply power, MB the electric circuit on the motherboard that connect

each of these components will work. Circuit function provides a place to

transfer the signal & amp; voltage (power). PCB itself consists of several

layers (sometimes called layer), and each layer contains its own circuit

lines, and each line is complicated need not touch other lines which are not

related. The more layers on the motherboard (usually 4% u2013 8 layer)

then it will be more qualified, because it reduces the ganggungan

interference.
