Ways to Measure Speed
Speed can be expressed two ways:
- How long to do something once?
- Memory speed measured in access time
- How many times can you do it in one second?
- Processor speed measured in instructions per second
Convenient units are typically used
- “10 microseconds” rather than “0.00001 seconds”
- When comparing speeds, convert units first!
