What term describes a condition where the CPU performs efficiently while bus speed is slow?

The term "bottlenecking" refers to a condition in a computer system where the performance of the entire system is limited or restricted by a particular component. In this case, when the CPU is operating efficiently but the bus speed is slow, the data transfer rate between the CPU and other components becomes the limiting factor, meaning the overall system performance is hindered. This occurs because the CPU can process data quickly, but if the bus, which carries data to and from the CPU, cannot keep up with this speed, it creates a bottleneck.

This phenomenon can occur in various parts of a system where one component cannot facilitate the processing speed of another, thus restricting performance and causing delays. Understanding bottlenecking is important in optimizing system performance and ensuring that all components are balanced and capable of working efficiently together. Other options like overclocking, fragmentation, and latency describe different issues that do not specifically address the scenario of a slow bus speed impacting CPU efficiency.
