Select the correct statement(s) regarding decentralized (distributed) access control on a LAN. a. no centralized access process exists, and therefore each connected station has the responsibility for controlling its access b. data collisions are possible, therefore mechanisms such as CDMA/CD are required c. when a data collision occurs, the nearest station detecting the collision transmits a jamming signal d. all of the above are correct

D. all of the above are correct

Explanation:

The correct statements regarding the decentralized (distributed) access control on a LAN include:

• no centralized access process exists, and therefore each connected station has the responsibility for controlling its access

• data collisions are possible, therefore mechanisms such as CDMA/CD are required

• when a data collision occurs, the nearest station detecting the collision transmits a jamming signal.

Therefore, the correct option is all of the above.
