2. MOTHERBOARD
 Circuit Of Motherboard

3.  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.

4.  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

5. 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.

6.  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.
