Final answer:
The question compares CSMA/CD and CSMA/CA in the context of wired and wireless communication.
Step-by-step explanation:
The subject of this question is Computers and Technology and the grade level is High School. The question compares CSMA/CD with CSMA/CA in the context of wired and wireless communication.
CSMA/CD stands for Carrier Sense Multiple Access/Collision Detection and it is a protocol used in wired networks. It helps to minimize collisions by sensing the carrier signal before transmitting data and detecting collisions when they occur.
- An example of CSMA/CD is Ethernet where devices listen for traffic on the network and wait for a clear channel before transmitting.
CSMA/CA stands for Carrier Sense Multiple Access/Collision Avoidance and it is a protocol used in wireless networks. It aims to avoid collisions by using a reservation-based mechanism where devices reserve the channel before transmitting.
- An example of CSMA/CA is Wi-Fi where devices contend for the channel using a backoff algorithm to avoid collisions.
