Which PDU format is used when bits are received from the network medium by the NIC of a host?

Explanation:
Bits arriving from the network medium are handed to the Data Link Layer as a frame. The NIC converts the recovered bit stream into frames, which are the PDU used on a single link to carry data between devices. A frame includes MAC addresses for local delivery and an error-detection field, helping ensure the data is correctly received on that link. Segments and packets belong to higher layers (Transport and Network), and a file isn’t a PDU in this context. So the frame is the appropriate PDU for data received by the NIC from the medium.
