Detailed explanation-1: -True or False? When a frame is encoded by the physical layer, all bits are sent over the media at the same time. False. The physical layer of the receiving devices passes bits up to which higher level layer?
Detailed explanation-2: -At the Physical layer of the receiving node, the signals are converted back into bits. The bits are then examined for the start of frame and end of frame bit patterns to determine that a complete frame has been received. The Physical layer then delivers all the bits of a frame to the Data Link layer.
Detailed explanation-3: -The OSI physical layer accepts a complete frame from the data link layer and encodes it as a series of signals that are transmitted onto the local media. The delivery of frames across the local media requires the following physical layer elements: The physical media and associated connectors.
Detailed explanation-4: -Throughput is the measure of the transfer of bits across the media over a given period of time.
