How does a device use CSMA/CA technology to avoid collisions?

  • It monitors the media and only begins to transmit when the media is free.
  • It sends a notification before transmitting when the media is free.
  • It uses a full-duplex channel for communication.
  • It waits for a token before transmitting.

Explanation: In CSMA/CA, the device examines the media for the presence of a data signal. If the media is free, the device sends a notification across the media of its intent to use it. The device then sends the data. This method is used by 802.11 wireless networking technologies.
