What is Front-side bus?

Front-side bus, short for FSB, is a communication interface that acts as the main link between the CPU and system memory; Other components of the chipset and motherboard. It was actively used in computer architecture in the early 1990s and early 2000. And because the speed of this communication link could be a "bottleneck" in the computer system, it was View is an important measure of computer performance.

What is FSB? Picture 1

FSB connects the following components to the CPU:

1. System chipset
2. System memory
3. Graphics card through the north bridge (northbridge)
4. Other input and output devices
5. PCI card

FSB is a prominent computer architecture component that allows CPUs to communicate with different computer system resources. It connects the system memory, input, output peripherals (I / O) and other motherboard components to the CPU and acts as the main transport link for the data around the hardware. computer.

The FSB speed is measured in hertz (Hz) and is usually expressed in proportion to the CPU speed. For example, the processor running at 2.4 GHz with 400 MHz FSB will have a CPU / FSB ratio of 6: 1.
