Central Hub for Communication: The motherboard acts as the backbone of the computer, with electrical pathways (called buses) that allow data transfer and coordination between the processor, memory, storage, and other hardware
Power Distribution: It receives power from the power supply and then distributes the correct voltage and current to components like the CPU, RAM, expansion cards, and drives.
Component Integration: The motherboard has sockets and slots for important components (e.g., CPU socket, RAM slots, PCI/PCIe slots) and connectors for drives and external ports (e.g., USB, Ethernet, audio).
Expansion and Upgrade Support: Via its expansion slots, users can add more hardware such as graphics cards, sound cards, Wi-Fi adapters, and more, enabling upgrades and customization.
System Management: It contains a BIOS/UEFI chip, which is essential for booting the computer and managing hardware configuration at startup.
Form Factor and Compatibility Determination: The motherboard's design (size and shape, called the form factor) determines what kind of case, power supply, and components the system can use.
