Collsion, Multiple Access, sensing, Transmission.


"Sense and Transmit" this approach is used in CSMA to provide maximum Through Put. Each interface must wait until there is no signal on the channel, and then it can begin transmitting. If some other interface is transmitting there will be a signal on the channel, which is called carrier. All other interfaces must wait until carrier ceases before trying to transmit, and this process is called Carrier Sense. All Ethernet interfaces are equal in their ability to send frames onto the network. No one gets a higher priority than anyone else, and democracy reigns. This is what is meant by Multiple Access. Since signals take a finite time to travel from one end of an Ethernet system to the other, the first bits of a transmitted frame do not reach all parts of the network simultaneously. Therefore, it's possible for two interfaces to sense that the network is idle and to start transmitting their frames simultaneously. When this happens, the Ethernet system has a way to sense the "collision" of signals and to stop the transmission and resend the frames. This is called Collision Detect. If two stations transmit the data at same time, then they become collide. So transmission becomes rescheduled using some methods or some algorithms such as backoff algorithm. Channels always try to maintain fewer collisions over different networks.
