Power Transfer: When you turn on the computer, the power supply sends electricity to the motherboard, powering all the components. Data Movement: Data travels across the motherboard through data buses, which connect different parts like the northbridge and southbridge. Northbridge Function: - Manages connections to the CPU, RAM, and PCIe slots. - The CPU processes data sent by the RAM, and this data is then either copied or moved to expansion cards (like graphics cards) via PCIe.  HOW DOES A MOTHERBOARD WORK? Southbridge Function: ⚬ Controls connections to the BIOS, USB ports, SATA (for hard drives and SSDs), and PCI bus. ⚬ Signals to the BIOS allow the computer to start up. ⚬ SATA connections power devices like hard drives and optical drives. Data Flow: ⚬ Data is sent as electrical signals through the motherboard's circuits, traveling between different components. ⚬ These signals are encoded in binary (1s and 0s) and are translated by the motherboard so that different parts of the computer can communicate. Instant Processing: The entire process happens almost instantly, with no noticeable  Mouse and Keyboard Connectors: Computers have connectors for the mouse and keyboard, either PS/2 or USB, which send instructions and receive responses from the computer. USB (Universal Serial Bus): USB ports connect external devices like printers and phones to the computer, allowing data transfer without restarting. Types include USB-A, USB-B, USB-C, and more. CPU (Central Processing Unit): The CPU is the computer’s brain, controlling all functions. CPUs can have one or multiple cores, with multiple cores handling multiple tasks at once.
