FSB (Frontside Bus) - Definition

FSB is an abbreviation For Frontside Bus. The Frontside Bus connects the computer's processor to the system memory (RAM) and other components on the motherboard. These components include the system chipset, AGP video card, PCI devices, and other peripherals. Because the FSB serves as the main path from the processor to the rest of the motherboard, it is also called the System Bus. The speed of the Frontside Bus is measured in Megahertz or Gigahertz, just like the Central Processor Unit (CPU).
