What is another term for the system bus in a computer?

The term "system bus" is often synonymous with "front side bus" (FSB). The front side bus refers to the communication system that transfers data between the processor and the main memory, as well as between other components like the graphics card. This bus plays a crucial role in the overall speed and performance of the computer system since it facilitates the necessary communication among the major hardware components.

The other options represent specific types of buses or concepts in computer architecture but do not directly equate to the "system bus." For example, the data bus typically refers to the pathway over which data is transferred, but it doesn’t encompass all the functions carried out by the system bus itself. The back side bus is used specifically for communication between the CPU and the cache memory, and the memory bus is focused primarily on connecting the main memory to the processor. While these components are important for a computer's operation, they do not replace the broader role of the system bus or its definition as the front side bus.
