Ethernet



Just to be clear, the first syllable is pronounced like "Heath" as in Heath Bar, not like "Beth." I found this out the hard way (ridiculing laughter), but at least you don't have to. Ethernet is the most common type of connection computers use in a local area network (LAN). The two most widely-used forms of Ethernet are called 10BaseT and 100BaseT. In a 10BaseT Ethernet, data transfer speeds can reach 10 mbps (megabits per second) through a copper cable. In a 100BaseT Ethernet, transfer speeds can get up to 100 mbps. (Bet you wouldn't thave guesses that.) There is also a new technology called "Gigabit" Ethernet, employed by some of the latest Apple PowerMacs, where data Transfer Rates peak at 1000 mbps. Now that's fast.

The maximum size of an Ethernet frame is 1518 Bytes.

66 Bytes are used for overhead (TCP,IP, LLC-Header, MAC-Header and FCS-Trailer)
