16 Components of the Motherboard

CPU Fan (Cooler):

The CPU fan cools down the CPU (heat generated). This means that the CPU cannot get

over heated. This is why computers laptops and phones do not get over heated and do function.


A computer’s memory stores numbers in huge amounts of cells that are addressed and can be quickly accessed by the CPU to perform calculations. There are two main types of computer memory, RAM (read only memory) and RAM (random access memory). RAM contains pre-written software and data that the CPU can only read, while RAM can be accessed and written to at any time.


The CPU or known as the processor is the brain of a computer. That is because it manages and handle what is happening and where the different information in a computer go. Also it's where all the processes are being carried like thoughts in your brain. The central processing unit (CPU) is the brain of your computer. It handles all the instructions you give your computer, and the faster it does this, the better. Learn about how a CPU processes instructions and how computer engineers are continuously coming up with ways to make it go faster.


The Northbridge is an Intel chip which communicates with the CPU and controls its interaction with memory. The chip has two parts which are called the Graphics and AGP Memory Controller Hub.


The Southbridge manages the basic forms of input/output (I/O) such as USB. The Southbridge is one of the two chips in the core logic chipset. It carries through the slower capabilities.

VGA Port:

The VGA Port is a video graphics array. It is a three row of fifteen pins connector. It is found on many video cards, computer monitors and high definition television sets. On laptops or any other small devices it is sometimes used in a normal sized VGA connector.

DVI Port:

The DVI Port is a digital visual interface. On televisions to connect things you usually plug them into HDMI, but to connect a computer to the television you plug it into the DVI Port or the VGA. If you are connecting a DVI computer to a VGA monitor this is the cable you need.


The USB is a data storage device that includes flash memory with an integrated Universal Serial Bus interface. USB flash drives can be removed or written again. It is used to connect computers to devices like digital cameras, printers, scanners and external hard drives.


The NIC is a card that allows the computer connect to a network. It is kind of like an Ethernet card and an network adapter. With this you can connect to home network or the Internet using an ethernet cable with an RJ-45 connector.

Audio Jacks:

The audio jack is where you plug in headphones and speakers. They are found on many types of audio equipment and musical instruments that have sound sources. This is why we have microphones and loudspeakers on computers, they can even be on various types of devices.

AGP Slot:

The AGP slot is where you place a graphics card. It is a high speed point to connect the graphics card to the computer system. Its original design was made for the connections of the video card.

PCI Slot:

A PCI slot is a parallel bus. Attached devices can even take the form of an intergrated circuit fitted onto the motherboard itself. It is used for hard-drives, RAM, GPU, RAID controllers etc.

PCI-E Slot:

The PCI-E slot is 16 lanes that connect to the PCI express. This means when you install a video card it will have the x16 bandwidth available and when you connect two video cards it will have the x8 bandwidth available.

CMOS battery:

The CMOS battery is powered by a small battery and it means when the computer shuts down or something everything will be saved after the accident. It is used for this exact reason and if computers did not have this it would be bad.

SATA Port:

The SATA port is a computer bus interfacr and it has a cable directly plugged into the motherboard. The host bus is connected to mass storage devices like hard disk drive and optical drives.

IDE Connector:

The IDE connector is integrated into the drive. Enhanced IDE are common drive interfaces found in IBM compatible computers. The IDE channels connect onto the motherboard. It is used for hard drives and CD and DVD drives.
