CSMA/CA

CSMA/CA (Carrier Sense Multiple Access with Collision Avoidance) is a method used in wireless networks to prevent data collisions. Before sending data, a device listens to check if the airwaves are clear. If the channel is busy, it waits for a random time before trying again. Once the channel is free, it transmits its data, sometimes sending a small notification first to alert others. This process helps multiple devices share the same wireless space efficiently, reducing the chances of data interfering with each other and ensuring more reliable communication.
