What is the difference between collision detection and collision avoidance

If a signal is detected, the sender starts a counter with a random value and then waits.

Once this counter runs down, the sender will try again. This process repeats until the sender can send the data. The part where the transmission waits to send is Collision Avoidance in action.

Once the line is clear, the station sends out a set of test data, and if no collisions are detected, it then sends the full payload of data. After the transmission completes, the receiver sends an acknowledgment telling the sender that it has received all the data. If the sender does not receive an acknowledgment from the receiver, it will then start transmitting the data all over again. This is because wireless networks often have multiple stations that can see an access point, but not one another.

The Wap and then halts all other traffic while the station sends its data. These things happen so quickly that we don't even know they are happening. This feature gives wireless users a smooth experience. This was a protocol that was used in slower and less complex early networks.

On these networks, computers could only send or receive data in one direction. If a transmission were already in progress, then the computer that wanted to send data would wait for a random amount of time before trying again.

In the It detects that the shared channel for broadcasting is busy and interrupts the broadcast till the channel becomes available. After all, wireless transmitters desensitize their receivers during packet transmission.
