Motherboard components and Functions

Motherboard, or often also we know the name mainboard, motherboard, MB, or system board is a hardware device in the computer system in the form of printed circuit board (PCB).

Its function is to connect all components of a computer. The motherboard can be regarded as the backbone (backbone) of the computer system, all components of a computer is definitely connected to the motherboard, either directly or indirectly.

Motherboards are produced in a variety of sizes, some made specific to a particular system brand. However, most modern mobo made to ready fitted to a wide range of casing sizes. Mobo is installed inside the casing with the facing side of the casing is easy to open, and tightened with a screw.

The parts of the motherboard:

chipset
The first and most important part of a motherboard chipset, which serves as a liaison between the processor interface with various external components and buses. This chipset can determine and assess the features and capabilities of a motherboard.

There are two groups of common chipsets we have encountered in the market. Intel chipset group, which can only be used for Intel CPUs, and AMD chipsets for AMD processor output. Both groups were subdivided to various types of generation chipset that continues to grow.

Socket / CPU Slots
Socket is a "bersemayamnya" processor on the motherboard. Just like chipset, socket is also divided on the various types, depending on the type of processor supports.

Basic Input Output System (BIOS) chip
BIOS is a chip that stores the software to control the hardware and serves as an interface between the hardware and the operating system (OS). BIOS used by the computer to prepare prosess boot (startup) and check the readiness of the system and hardware before the computer starts.

Complimentary Metal Oxide Semicondutor (CMOS) Battery
CMOS is a battery to supply power to a small memory on the motherboard that is used to store computer configuration settings, time, etc. CMOS maintain that we do not need to configure these things every time we turn on the computer

memory Slots
Shaped slots rather long and slender serves as a place-install it Random Access Memory (RAM). In the modern computer era, almost all motherboard has at least two RAM slots, even on high-end computer specs there motherboards are equipped to 6 RAM slots.

VGA Slots (Graphic Card Slot)
This slot is used to install the components of a graphics card (video card). In modern computers, generally in the form of slots with PCI-Express interface. In the high-end motherboard can accommodate up to 3 slot graphics card.

expansion Slots
Expansion slots used to install additional devices such as sound card, LAN card, etc.

Storage Drive Connector
Its function is to connect storage devices like Hard Drive, Optical Drive, SSD, and external storage devices. Usually in the form of interface S-ATA (Serial Advanced Technology Attachment) / ATA.

Other Ports
In addition to slots above, there are several ports on the motherboard which is very essential functions such as:

• Pin power port 24/20 Pin - to connect the motherboard to the power supply unit (PSU).
• Port Power 4pin / 6pin - to supply power to the processor.
• Port for the power / reset on the front of the casing.
• Front connector port for USB and Front Audio.

Besides a number of slots and ports above, there is also a part of the motherboard facing the outer casing and can be accessed from the outside. This section is called the Back Panel I / O, usually located on the side of a mobo position, and facing the rear of your case.

Back panel has several connectors are commonly encountered are :

• PS / 2 port - port for connecting a mouse / keyboard.
• USB Port - The port to connect peripherals with USB interface.
• S / PDIF port - Connect the audio connector S / PDIF
• RJ-45 Lan Port - Connect the LAN network cable
• Audio Port - Connects to the motherboard audio system / speakers.
• etc.
