PARTS OF THE MOTHERSDBOARD MOTHERBOARD It is a printed circuit board that is the foundation of a computer and allows the CPU, RAM, and all other computer hardware components to function and communicate with each other.  4 pin CPU Fan pin-out These are usually used by CPU fans with higher power consumption. 12v 4 pin CPU Power Connector  This device senses the CPU voltage requirements and calibrates it self to provide the proper voltage to run the CPU. 24 pin ATX Power Connector Main power connector of the motherboard. Front Panel Connectors  The front panel connector is where the connectors of hard disk drive activity lights, case speaker, reset button, power on or off button, computer power on light, and key lock are connected to make them function smoothly Types of System Panel Cables BIOS  Short for Basic Input, Output System, the BIOS, or System BIOS is a chip located on all motherboards that contain instructions and setup for how your system should boot and how it operate. CMOS Battery  To keep the clock chip running even when power is of. North Bridge  It is a chip inside a computer that connects the central processing unit (CPU) to other primary components in the system. These components include ram, fsb, PCIE, and agp. South Bridge  A Southbridge chipset handles all of a computer IO functions, such as USB, audio, serial, BIOS, ISA bus, and IDE channels. USB Header USB header is a group of pins, typically on a computer motherboard or expansion card, to which an internal USB cable can be attached to provide extra USB ports. Memory Slot A memory slot, memory socket, or ram slot is what allows computer memory to be inserted into the computer. PCI Slot Provides a medium to expand the capabilities of the PC, by adding like modems cards, audio cards, ethernet cards. AGP Slot  AGP slot is one of the types of video card available. AGP cards are automatically detected as in-built video cards when connected to AGP slot of system. AMR Slot  The audio/modem riser, also known as an AMR slot, was designed by Intel to interface with chipsets and provide analog functionality, such as sound cards and modems, on an expansion card. CPU  CPU also referred to as a central processing unit, is the hardware within a computer that carries out the instructions of a computer program by performing the basic arithmetical, logical, and i/o operations. CPU Socket  A CPU socket or CPU slot is a mechanical component that provide mechanical and electrical connections between a microprocessor and a printed circuit board CPU Fan  CPU fan is attached together with a heat sink on the motherboard, CPU fan is used to prevent overheating of the processor on the motherboard. Heat Sink  Heat sink is a passive heat exchanger component that cools a device by dissipating heat into the surrounding air. It is used to cool central processing units or graphic processors.
