in a book about ccna:
Error detection does not imply recovery; most data links, including 802.5 Token Ring and 802.3
Ethernet, do not provide error recovery. In these two cases, however, there is an option in the
802.2 protocol, called LLC type 2, that does perform error recovery. SNA and NetBIOS are the
typical higher-layer protocols in use that request the services of LLC2.
i want to ask a series of question.
is ethernet including with LLC2?
commonly our lan uses ethernet or 802.3,LLC2 or LLC1?which relationship between ethernet and 802.3?LLC2 and LLC1?
