In what units are CPU speeds measured, and what does this measurement unit refer to? If one computer has a 2 GHz Celeron D processor and another has a 2 GHz PowerPC processor, does that imply they will be able to execute the same program in the same amount of time? Explain.
What will be an ideal response?
CPU speed is generally measured in gigahertz (GHz), which indicates how many billions of basic instructions a CPU can execute in a second. For example, a 2 GHz CPU can execute approximately 2 billion instructions in a second. Since different families of CPUs will provide different basic operations, performance comparisons based on CPU speed are not always accurate.
