Final answer:
In wireless networks, collisions cannot be detected, but they can be inferred using the CSMA/CD mechanism.
Step-by-step explanation:
In wireless networks, a collision cannot be detected, but collisions can be inferred using a mechanism called Carrier Sense Multiple Access with Collision Detection (CSMA/CD).
This mechanism works by monitoring the network for any activity before transmitting data. If a station detects that the network is busy, it waits for a random amount of time and then tries again. If multiple stations transmit data at the same time, a collision occurs. In such cases, the stations involved in the collision wait for a random amount of time before reattempting transmission.
