Which statement describes the operation of devices accessing an Ethernet network?
- Each device monitors the media and sends a notification for its intention to send data first.
- To send data, each device waits for a token to be available.
- Each device monitors the media and sends data when the media is free.
- Each device in turn receives a frame. If the frame is not intended for the device, the device passes it along.
Explanation: Ethernet uses CSMA/CD as the access control method. With CSMA/CD, each end device monitors the media for the presence of a data signal. If the media is free, the device can transmit data immediately. The other options are operations with CSMA/CA and Token passing.
