Um... which technology? Ethernet? Token Ring? FDDI? ATM? Wet string?

Your question is a bit vague, because I'm not sure which technology you
are referring to. Cisco is a company that builds networking stuff - but
they are far from being the only one. Then too, we have no no idea what
your goal is. System Administrator? Network Administrator? Hardware
guy? See if you can find this HOWTO on your system (or use any search

There are a lot of facets to networking. Just talking about Ethernet which
is the most common type used, there are at least four fundamental types
(coax, twisted pairs, fiber, and wireless), with multiple data speeds
(twisted pair can be 10, 100 or 1000 megabits/second) and there are over
180 different data formats (or protocols) that can be found on Ethernet,
such as AppleTalk, IP, IPX, NetBEUI, and so on. Within _those_ protocols
or data formats are others - IP can carry over 130 protocols, such as TCP,
UDP, ICMP, IGMP, and so on. Note that we're not dealing with the content
of those protocols - TCP might be carrying mail, news, web pages, or who
knows what else.
Do you need to know about all of them? Probably not. But again, what are
you trying to learn?
