CSMA CarrierSense Multiple Access protocols are used to coor

CSMA (Carrier-Sense Multiple Access) protocols are used to coordinate access to a shared medium. This question is about CSMA protocols In general, and CSMA/CA and CSMA/CD In particular. With CSMA/CA, the transmitting nodes detect If there is a collision, and abort their transmissions. CSMA/CD is used primarily for wireless networks, where he probability for collisions is high. By listening (\"Carrier Sense\") before sending, CSMA protocols make sure that there can be no collisions. With CSMA/CD, the transmitting nodes detect if there is a collision, and abort their transmissions. CSMA relies on the presence of a common reference clock, to which all nodes are synchronized. By distributing transmission starting times in a randomized way, CSMA/CA reduces the probability that several nodes start transmitting at the same time, .

Solution

The following points are correct about CSMA/CA protocols

With CSMA/CA is used for wireless networks where their is a proablity for a collision.

By distributing transmission starting times in a randomized way , CSMA/CA reduces the proability that several nodes start trasmitting at the same times.
