are talking about when you are networking ?this is to avoid an intend message which is distinct to a particular address from beenreceive by a wrong address
If an access point receives data from a client station, it sends an acknowledgment to the client that the data has been received, this acknowledgment keeps the client from assuming that a collision occurred and prevent a data retransmission by the client.
bus
Data collisions occur when data is transmitted on the same medium at the same time. Therefore, to avoid data collisions, connect all hosts to a full duplex switch.
median
To prevent collisions.
Token
To prevent collisions between runner and fielder
to prevent any collisions or accidents
To prevent collisions and accidents on the water
Full Duplex Ethernet uses no network control protocal to prevent collisions. This is because full duplex has a deicated channell for transmit and receive. When communicating in full duplex mode, there is no area to have a collision.
