​PARTS OF MOTHERBOARD & THEIR FUNCTIONS

The motherboard is one of the components of the system unit that performs major functions to run our computer. All the devices (input & output) we use and other important parts of our computer are attached to our motherboard.

​1. CPU Socket

Ø Also known as CPU Slot or CPU Holder

Ø This component of the motherboard holds the CPU (Central Processing Unit) and allows replacing of the component without soldering.

2. RAM Holder

•Also known as Memory Holder or Memory Slot

•This component is where the memory module or memory card will be inserted.

•Some motherboard comes with two to four slots.

3. Power Supply Connector

•This part of the motherboard is where the power supply unit cable connector can be connected

•Types of PSU Connector

  1. 24 pins – main power connector that

      provides power to the motherboard

  2. 4 pins – provides power to the CPU

  3. 8 pins – provides power for faster dedicated graphics cards

4. Northbridge Chipset

•Also known as Memory Controller Hub

•This chipset handles the data-transfer of memory, CPU, and Video Card thus responsible for tasks that require the highest performance.

5. Southbridge Chipset

Ø This chipset component provides support for a wide variety of devices with many differing bus speeds and designs.

 

Ø Control over secondary buses such as USB, IDE, PS/2, BIOs and Ethernet.

6. CMOS or BIOS Chipset

• (Complementary Metal Oxide Semi-conductor)

is also a chipset which contains the BIOS (Basic Input Output System).

7. EIDE Slot/Port

Ø This part of the motherboard is where the IDE cables are connected intended for drives including Hard Disk Drive (HDD) and Optical Disk Drive (ODD).

8. SATA Port/Slot

Ø This is used to connect SATA drives into the motherboard including Hard Disk Drive (HDD) and Optical Disk Drive (ODD).

Ø SATA (Serial ATA) has a faster transfer rate than IDE

9. AGP (Accelerated Graphic Port)

Ø It was designed specifically for AGP video cards.

Ø It was originally designed as a successor to PCI-type connections for video cards.

11. PCI-EXPRESS Slot

Ø PCIe was designed to replace PCI, PCI-X, and AGP.

Ø It is the most recent and high-performance standard for expansion cards that is generally available on modern personal computers.

11. Front Panel Pins

Ø These are pins in the motherboard that will connect the Power Button, Reset Button, Power LED, Mini Speaker, USB ports and other ports to the motherboard

12. PS2 port

 It is used to connect PS2 mouse and keyboard

13. USB Port

This part of the motherboard is used to connected USB Devices and peripherals

14. HDMI Port

It is used to connect HDMI cable from the monitor to the motherboard

15. Active Display port

It is used to connect Active Display cable from the monitor to the motherboard

16. VGA Port

•It is used to connect VGA cable from the monitor to the motherboard

17. DVI Port

•It is used to connect DVI cable from the monitor to the motherboard

18. IEEE 1394a Port

• It is an interface standard for a serial bus for high-speed communications and isochronous real-time data transfer.

•It was developed in the late 1980s and early 1990s by Apple, which called it FireWire, in cooperation with a number of companies, primarily Sony and Panasonic.

​ IEEE 1394a Port

19. E-SATA Port

•It is a SATA connector accessible from outside the computer, to provide a signal (but not power) connection for external storage devices.

20. LAN Port

•Also known as Network Port

•LAN port allows a computer to connect to a network using a wired connection.

21. Audio Port

•An audio port is used for an audio device such as speakers, headphones or a microphone to be connected.
