2. The correct answer is False. When encoded, the bits making up a frame are transmitted over the media one at a time.
3. The physical layer receives frames from the data-link layer and converts it to bits for transmission. On the sending device the physical layer passes the transmitted bits up to the data link layer as a complete frame.
4. The physical layer receives frames from the data link layer for encoding and transmission.
