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 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). 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. What is printed circuit board of a computer system?A printed circuit board (PCB) is a board with circuits that connect electronic components together. PCB's are used in computers and other electronic devices and are made of an electrically non-conductive material, usually fibreglass.
What is the name of the printed circuit board in computer?PCB or Printed Circuit Board is the traditional name for the bare board of which you supply us with the layout data and which you use to mount your components on once we have delivered it to you.
What are circuit board components called?These PCB components include transistors, fuses, resistors and capacitors, which all play their part to ensure we have a smooth-running device – if one of these components fails, the entire PCB will fail to work and thus affect the functionality of the product itself.
