===Non-persistent===
Non persistent CSMA is a non-aggressive transmission algorithm. When the transmitting node is ready to transmit data, it senses the transmission medium for idle or busy. If idle, then it transmits immediately. If busy, it jumps to the final random waiting step of 1-persistent CSMA directly before repeating the whole logic cycle again: it does not persist in checking the busy channel trying to get its transmission through, hence the name. This approach reduces the chance of collision and results in overall higher medium throughput but with a penalty of longer initial delay compared to 1–persistent.
