P6. in step 4 of the csma/ca protocol, a station that successfully transmits a frame begins the csma/ca protocol for a second frame at step 2, rather than at step 1. what rationale might the designers of csma/ca have had in mind by having such a station not transmit the second frame immediately (if the channel is sensed idle)?

To avoid collision of transmitting frames.

Explanation:

CSMA/CA, carrier sense multiple access is a media access control protocol of wireless networks that allows for exclusive transmission of frames and avoidance of collision in the network. When a frame is not being sent, nodes listening for an idle channel gets their chance. It sends a request to send (RTS) message to the access point. If the request is granted, the access point sends a clear to send (CTS) message to the node, then the node can transmit its frame.

Many nodes on a wireless network are listening to transmit frames, when a frame is transmitting, the node has to wait for the access point to finish transmitting, so it sends a RTS message again to exclusively transmit a second frame.

answer; i believe the answer is tls,transport layer security;
