Hi all,

Recently a friend of mine asked me,on seeing a LAN,how to find its
type?, the only answer i could give her was , on seeing the cabling
used, we can say whether it is 10 Base T, or fast ethernet etc.

Well, you could start here and work your way thru the various types
that are/were available:

Perhaps one question to ask is what do you mean by "on seeing a LAN"?
You mean, the cable? The hosts communicating together? The switches?

If you mean that you see cable or wall sockets only, no attached
hosts, one easy way might be find the wiring cabinet and physcially
look at the switch(es) used to fan out to the various rooms. Look at
brand name and model number, and proceed from there.

If there are hosts connected, then you can always get at least an idea
by looking at the "properties" of the NIC in a few of the hosts. The
typical choices these days are not all that varied.
