Assuming you mean ``100BASE-T (half duplex)'' here... This is not
quite right. In a CSMA/CD medium access protocol, like that used by
Ethernet, the actual capacity of the link is always(*) somewhat less than
100%; the exact value depends on the precise parameters of the
transmissions at both ends.(**)

(*)In non-trivial conditions; i.e., when actual work is being done.
(**)I've heard numbers between 70% and 95%.
