A) the protocols for data routing to ensure that data arrives at the correct destination
B) the way data is formatted,converted,and encoded
C) the mechanism for communicating with the transmission media and interface hardware
D) the way that application programs such as electronic mail interact with the network
E) the protocols for structuring messages

Question

Quizplus · Accepted Answer

The physical layer of the OSI model is responsible for defining the mechanism for communicating with the transmission media and interface hardware. It deals with the physical characteristics of the transmission medium and specifies the details of the signaling functions which are required to transmit the data over the medium. It defines how the data is transmitted over the network and how it is converted into digital signals that can be transmitted over the physical medium. It is responsible for establishing and maintaining the physical link between devices. Therefore, option C is the correct choice.
