| 7.4.2 | NIC Layer 2 operations

NICs perform important Layer 2 data link layer functions, such as the following:

- logical link control - communicates with upper layers in the computer

- naming - provides a unique MAC address identifier

- framing - part of the encapsulation process, packaging the bits for transport

- Media Access Control (MAC) - provides structured access to shared access media

- signaling - creates signals and interface with the media by using built-in transceivers
