Document Summary
Csma/cd carrier sense multiple access / collision detected = 802. 3: token ring = collision free = 802. 5. If ring is broken, all connections are broken: but collision won"t occur, data is sent through a ring, 60,000 loops per second, bus topology = collisions. Connection backup (redundancy: fiber distributed data interface is faster than token ring. Metropolitan area network (kilometers, 10g/s: sonet topology ( synchronous optical net): (*~ multiple fddi models that are connected, high speed. Wan topology (mesh topology)(*~ visual note, a grid chart. Each cross contains a node aka a router ) Multiple paths to take in terms of sending data (fault tolerance) Wireless access point (wap) 802. 11 a, b, g physical. Wtls: the following security setting is provided by wtls: wireless secure socket layer (ip + port = socket ssl, wireless equivalent privacy (wep) Rc4 security(rivest cipher algorithm ) *~ just fyi not on mt or exam. Wireless mechanism to handle collision is called: csma/ca.
