What OSI physical layer term describes the capacity at which a medium can carry data? Group of answer choicesbandwidthairIEEEEIA/TIA

The term that describes the capacity at which a medium can carry data at the OSI physical layer is bandwidth.

Explanation:

1. OSI Model: The OSI (Open Systems Interconnection) model consists of seven layers, with the physical layer being the first. It deals with the physical transmission of data over various media.

2. Definition of Bandwidth: Bandwidth refers to the maximum rate of data transfer across a network path. It is typically measured in bits per second (bps) and determines how much data can be sent or received in a given amount of time.

3. Why Other Options Don't Fit:

   • Air: This does not specifically relate to a measurable capacity but rather describes a medium.
   • IEEE/IATIA: These are organizations that define standards for networking and telecommunications but do not refer to a specific capacity measurement.

In summary, the correct choice describing the capacity at which a medium can carry data in the OSI physical layer is bandwidth.
