Subsecond intervals refer to time measurements that are shorter than one second. These intervals are often used in various fields such as computing, telecommunications, and sports timing. For example, in computer networking, data packets may be transmitted and received in subsecond intervals to ensure efficient communication. In sports, subsecond intervals can be crucial for timing events like races or sprints. Timing systems that measure performance in athletics often require precision to the millisecond or even microsecond level. This level of accuracy helps in determining winners and improving athletes' performance.
