A Frontside Bus (FSB) is the component that connects the processor (CPU) in your computer to the system memory. The speed of the FSB determines how quickly data can be sent to the processor, which in turn affects overall computer performance.
The FSB speed depends on the processor and motherboard chipset being used, as well as the system clock. It is measured in megahertz or gigahertz and is usually a ratio of the processor speed. For example, a Pentium 4 processor running at 2.4 GHz has an FSB speed of only 400 MHz, while a Power Mac G5 with a 2.0 GHz processor has an FSB of 1.0 GHz.
A smaller ratio between the CPU and FSB results in more efficient processing and faster overall performance. When the ratio is high, the processor often has to wait for data to be sent over the system bus before it can process new data, which can create a bottleneck to the computer’s performance.
