What is a primary role of the Physical layer in transmitting data on the network?
- create the signals that represent the bits in each frame on to the media
- provide physical addressing to the devices
- determine the path packets take through the network
- control data access to the media
Answers Explanation & Hints: The OSI physical layer provides the means to transport the bits that make up a frame across the network media. This layer accepts a complete frame from the data link layer and encodes it as a series of signals that are transmitted to the local media.
