What OSI physical layer term describes the amount of time, including delays, for data to travel from one point to another?

  • latency
  • fiber-optic cable
  • air
  • copper cable
Explanation & Hint:

The OSI physical layer term that describes the amount of time, including delays, for data to travel from one point to another is “latency.” Latency encompasses the total time delay experienced by data as it travels from its source to its destination, and it includes factors like propagation delay, transmission delay, and processing delay. It is a key factor in determining the performance of a network or communication system.

The other terms, such as “fiber-optic cable,” “air,” and “copper cable,” are not OSI physical layer terms but rather refer to different physical media or transmission mediums used in networking.
