Which topology uses the CSMA/CD (Carrier Sense Multiple Access with Collision Detection) mechanism?
Correct answer: B. bus
- A. token ring
- B. bus
- C. star
- D. mesh
Explanation
CSMA/CD is a media access control method used in bus topologies. In a bus network, all devices are connected to a single shared cable. When a device wants to transmit data, it first listens to the cable to sense if another device is already transmitting (carrier sense). If the cable is idle, the device transmits its data. However, if there's a collision (two devices transmitting simultaneously), both devices detect the collision and stop transmitting for a random time before retrying (collision detection).
