Both Physical and Data layer determines the frame synchronizations
Both Physical and Data layer uses protocol to describe the mechanical, electrical, functional and procedural means to activate, maintain and deactivate physical connections for a bit
The physical layer is concerned with bit by bit delivery and Data layer is concerned with signal equalization
The physical layer converts a signal from one form to another so that it can be physically transmitted over a communication channel and the data layer is concerned with the transmission of messages on a single local networkCorrect
