Latency is the delay between the occurrence of an event and a subsequent event. It can also be defined as any delay in time between a request and a response.
It is worth noting that electronic traders must use fast computer systems to minimize latencies.
Question
Which of the following statements about latency is the most accurate?
- High latency causes an improved overall efficiency of the market.
- Low latencies improve the overall efficiency of the market.
- Using fast computers increases latency.
Solution
The correct answer is B.
Low latency means that there is less delay time between a request and a response. Therefore, low latency leads to high productivity in the system; thus, the overall efficiency is improved.
A is incorrect. When there is high latency, much time will be wasted in the system. This will cause low productivity in the system.
C is incorrect. The use of fast computers reduces latency because assigned tasks are executed quickly.
