FSB and BSB

FSB

 

Short for Front Side Bus, FSB is also known as the Processor Bus, Memory Bus, or System Bus and connects the CPU with the main memory and is used to connect to other components within the computer. The FSB can range from speeds of 66 MHz, 133 MHz, 100 MHz, 266 MHz, 400 MHz, and up. The FSB is now another important consideration when looking at purchasing a computer Motherboard or a new computer. 

The FSB speed can generally be set either using the system BIOS or with jumpers located on the computer motherboard. While most motherboards will allow you to set the FSB to any setting, ensure that the FSB is properly set unless you plan to Overclock the computer.

Issues such as hardware lockups, data corruption or other errors may arise with older hardware, such as old SCSI cards and a newer front side bus such as a motherboard with a 100MHz FSB. Verify your component's compatibility with your motherboard and/or Motherboard FSB speed. In addition, verify that the FSB is properly set; overclocking the computer can also cause these types of issues.

 

BSB

 

Sometimes abbreviated as BSB, the back side bus is the computer bus used to connect the CPU to the L2 Cache and was first introduced with the Intel Pentium Pro. The back side bus is a part of the CPU and has a speed that is dependent on the speed of the processor.

学校的教材总是很久远的..好长时间总把fsb,系统总线,pci总线,等等其他总线搞混淆..

fsb就是系统总线.其他总线通过北桥接进来
