A CDE Definition
Also called the "system board," "main board" "base board" or "logic board," it is the primary printed circuit board in a computer or other electronic device. In a modern desktop computer, the motherboard contains the CPU and RAM sockets as well as the chipset, which houses the control circuits for all the peripheral devices (drives, keyboard, mouse, etc.). A motherboard typically also has a PCI-Express slot for a high-end graphics card and PCI slots for additional peripherals. Laptop motherboards do not have expansion slots for more peripherals.
