Net+ All-in-one exam guide question

| Hi,
On pg.107 Mike mentions
"10Base2 NICs have a built-in transceiver...."
On pg.211
"For example, you can add a transceiver to a 10Base5 NIC to convert the
15-pin DIX(AUI) connector to RJ-45. 10Base2 doesn't have a transceiver, but
some ports have an extra 10Base2 port, ..."
Is he talking solely about "external" transceivers? Or because 10Base2
already has a built-in transceiver, you can't add an additional transceiver
to convert the connector (from BNC to RJ-45)? Whereas, a transceiver can be
directly attached to a 10Base5 NIC to alter the connector (and replace the
external transceiver)? Can someone please clarify?
Thanks,
V
p.s. Side note, do 10xBaseT NICs have built-in transceivers or rather handle
the job of a transceiver?

I think you are refering to 2 different devices here.
To switch from a DIX connector to an RJ45, you would use a media
filter which keeps the wire pairs in the correct order.
The TRANSmitter-reCEIVER is comparable to modem in that it actually
transmits and receives the electrified bit patterns.
I haven't read his book so I cannot answer on what he meant to say
here.

| V,
10Base5 and 10Base2 use two physicall different transcievers but they
function similarly.
10Base5 uses a transciever that attache to the RG-8 cable via vampire taps.
From the transciever a drop cable is attached that connects to the
workstation.
10Base2 transciever is built right into the NIC and is connected by the RJ45
connector to the UTP cable (or coax in older systems)
10BaseT NICs have the transciever built into the NIC as well.
Hope this helps,
