Answer 2

Option (B) is the correct answer to this question.

Explanation:

CSMA / CA stands for Carrier-sense multi-access / collision prevention.

• It is a multi-access protocol used by the IEEE 802.11 Wireless LAN standard.
• It is based on the concept of avoiding collisions by using various formulas to avoid accidents among channels.
• CSMA / CA is seeking to reduce the occurrence of such collisions and, at the same time, to have a strategy for how to proceed if a collision occurs.
• The protocol is also essential because communications in wireless networks can not be carried out in the same order (because of the technologies used) as would be the case with a cable.
