What's the textbook?

Flamed_Chip · Mar 12, 2007

About the best introductory text to networking you will find is Andrew Tanenbaum's Computer Networks.

Also, that information should be very easily obtainable from google/wikipedia etc.

Also,
try to rephrase your questions for google. I just changed the wording around and got at least a full page of results for networking layers.

Thx alot guys, the only thing that i not sure about, is that a switch works at layer 3, however i am sure that when workinbg out which port to send out it uses a protocol that works at a differant layer, am i correct?

thx

Most switches work at the layer 2 level (forwarding tables are developed according to MAC address). Layer 3 switches are mostly routers with hardware to manage what a router's software would normally do at a LAN level. A layer 3 switch will often be mistaken for a router because they do much of the same, with the switch not having WAN ports.

While layer 2 switches are predominant, they are making way for smarter and faster layer 3.
