The front side bus formerly connected the Northbridge Controller to the CPU (a way of communication) it still has the same communication, but it is not called FSB, it is called a HyperTransport Bus.
The bus between the CPU and memory on the motherboard. Also called the memory bus, front-side bus, local bus, or host bus.
The main function of the front side bus is to connect the computer to the motherboard. It also connects the computer to the RAM or random access memory.
The front side bus connects the CPU on the motherboard to the Northbridge. Front side bus speed is in preference to how much data can move across the bus simultaneously, and is measured in megahertz.
The backside bus is 32-bit wide and the front side bus is 64-bit wide. This because of the dual processing design.
front side Bus...(FSB) or System Bus
The Front Side Bus (FSB) connects the processor (CPU) in your computer to the system memory.
(FSB) front side bus host bus
For the Pentium the front side data bus is 64 bits wide. The back side is 32 bits wide.
Megahertz
System Bus or Front side bus
System bus, memory bus, front side bus (FSB), host bus, local bus, or external bus.
