How would you calculate the theoretical throughput of a bus?

A) Bus width x CPU clock speed

B) Installed RAM in bytes x bus clock speed

C) Bus width x bus clock speed

D) Installed RAM in bytes x CPU clock speed

E) Just look at the speedometer. Try to keep it under the limit next time.


The answer: C) Bus width x bus clock speed

The speed of a system bus is independent of any installed memory or individual processor speeds.

An important consideration of the very first IBM personal computer was including standardized expansion slots so the end-user could customize their system. In this video, you’ll learn about bus architectures and expansion slots, including PCI, PCI Express, AGP, and CardBus.
