MOTHERBOARD

a printed circuit board containing the principal components of a computer or other device, with connectors into which other circuit boards can be slotted.

PARTS OF THE MOTHERBOARD

1. Back Panel Connectors & Ports-

                                Connectors and ports for connecting the computer to external devices such as                                 display ports, audio ports, USB ports, Ethernet ports, PS/2 ports etc. See                                         image below for a close-up view.

2. PCI Slots

                    -PCI: Peripheral Component Interconnect

                  Slot for older expansion cards such as sound cards, network cards, connector cards.                      See image below for a close-up view.

3. PCI Express x1 Slots

                      -Slot for modern expansion cards such as sound cards, network cards (Wi-Fi,                                  Ethernet, Bluetooth),connector cards (USB, FireWire, eSATA) and certain low-end                          graphics cards. See image below for a close-up view. - 

4. PCI Express x16 Slot
                       Slot for discrete graphic cards and high bandwidth devices such as top-end solid                               state drives. See image below for a close-up view. - 

5. Northbridge

                        Also known as Memory Controller Hub (MCH).

                        Chipset that allows the CPU to communicate with the RAM and graphics card. 

6. CPU Socket- is the place where you can insert the CPU.

7. ATX 12V Power Connector- 

                         Connects to the 4-pin power cable of a power supply unit which supplies power to                                                     the CPU. 

8. Front Panel USB 2.0 Connectors- Connects to USB 2.0 ports at the front or top of a computer case. See image above for a close-up view.

9. Front Panel Connectors- Connects to the power switch, reset switch, power LED, hard drive LED and front                                                         audio ports of a computer case. See image above for a close-up view.

10. IDE Connector- Connects to older hard drive disks and optical drives for data transfer. See image above for a                                     close-up view. Have been replaced over by SATA connectors - 

11. CMOS Battery- Supplies power to store BIOS settings and keep the real-time clock running. See image above                                 for a close-up view.

12. Southbridge- Also known as the Input/Output Controller Hub (ICH).
                            Chipset that allows the CPU to communicate with PCI slots, PCI-Express x 1 slots (expansion                                     cards), SATA connectors (hard drives, optical drives), USB ports (USB devices), Ethernet ports                                 and on-board audio.

13. SATA Connectors- Connects to modern hard disk drives, solid state drives and optical drives for data                                                     transfer. See image above for a close-up view. - 

14. Fan Headers-Supplies power to the CPU heat sink fan and computer case fans. See image above for a                                         close-up view.

15. RAM Slots- Is where you can insert the RAM

16. ATX Power Connector- Connects to the 24-pin ATX power cable of a power supply unit which supplies                                                             power to the motherboard. 

17. mSATA Connector- Connects to a mSATA solid state drive. In most cases, this SSD is used as cache to                                                     speed up hard disk drives, but it's  possible to re- purpose it as a regular hard drive.

18. Front Panel USB 3.0 Connector-Connects to USB 3.0 ports at the front or top of the computer case. 

19. Power & Reset Button - Onboard button to turn on, turn off and reboot the computer.
