How many milliseconds (ms) are in 1 second?
- A 100 ms
- B 1,000,000 ms
- C 1,000 ms
- D 60 ms
Answer: C. 1,000 ms
The prefix 'milli' denotes one-thousandth ($10^{-3}$), meaning there are exactly 1,000 milliseconds in a single second. In modern computing, a second is a relatively long period of time; most critical performance metrics, such as network Round-Trip Time (RTT) or database query latency, are measured in milliseconds. Understanding this scale is vital, as a delay of even 100ms is perceptible to humans and can negatively impact the user experience of highly interactive applications.
