Can you post the answers plz
Answer:
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.

If we intend to include a servo motor as an actuator, the feature that we should include when selecting a microcontroller is pulse width modulation pin.
<h3>What is a microcontroller?</h3>
It should be noted that a microcontroller simply means an integrated circuit that designed to govern particular operation in a system.
In this case, if we intend to include a servo motor as an actuator, the feature that we should include when selecting a microcontroller is pulse width modulation pin.
