The differences are quite crucial. ALOHA is a broadcast radio packet network,
which doesn't have collision detect and probably not carrier sense either. So
it's about 1/3rd of Ethernet -- just MA. :-) A consequence is that the
theoretical channel capacity is also about 1/3rd; ALOHA tops out around 30% of
data rate, while Ethernet -- thanks to CS and CD -- can reach pretty much the
full wire capacity.
