|
When a frame is encoded by the physical layer, all bits are sent over the media at the same time.
|
|
True
|
|
|
False The physical layer encodes the frames and creates the electrical, optical, or radio wave signals that represent the bits in each frame. These signals are then sent over the media, one at a time.

|
None of the above

Explanation:
Detailed explanation-1: -When a frame is encoded by the physical layer, all bits are sent over the media at the same time. Explanation: The correct answer is False.
Detailed explanation-2: -The physical layer is the first and lowest layer of the Open Systems Interconnection (OSI) communications model. The physical layer’s function is to transport data using electrical, mechanical or procedural interfaces.
Detailed explanation-3: -The physical layer carries the signals for all of the higher layers. This layer plays with most of the network’s physical connections-wireless transmission, cabling, cabling standards and types, connectors and types, network interface cards, and more-as per network requirements.
