Ethernet uses a carrier sense multiple access with
collision detect scheme. Explain the terms in italics.
Even using CSMA/CD, There is still a finite probability of
collision between packets. Explain why.
Assume that two computers are sending 1000 byte packets over a
shared channel that operates at 64000 bits per second. To ensure
fairness, after sending a packet, the sending machine must wait
200 microseconds before sending another packet, whilst a waiting
machine can send a packet 100 microseconds after packet is sent.
How long will it take the two machines to each send a MByte file?
Switched networks are taking over from shared media networks
as Local Area Networks. Why?
