What is Backside Bus?

The buses that transfer data to and from a computer's Processor fall into two categories. These are the front and rear buses, respectively. Unexpectedly, there is no connection between them and the frontside and backside airs snowboarders speak about.

The backside bus transmits data to and from the computer's secondary cache whereas the frontside bus delivers information between the CPU and memory. Near the CPU, frequently used functions and other data are kept in the secondary, or L2 cache. As a result of being able to repeat operations more quickly, the computer's CPU can operate more effectively.

Information from the L2 cache is delivered over the backside bus to the processor when it is required. The rear bus's clock speed cannot afford to lag behind since this procedure must be completed very quickly. The backside bus is often just as fast as the CPU because of this. On the other hand, the frontside bus normally operates at a speed that is half as fast as the CPU.
