All stations are synchronized, and transmissions are only permitted to begin at the start of a slotExplain slotted ALOHA protocol with efficiency calculation The fundamental principle behind slotted ALOHA is that if two or more stations transmit within the same slot, a collision occurs, and their data may be lostThe throughput for slotted ALOHA isS = G x e-G. The maximum throughput Smax = 0.368 when G=1. • The throughput of CSMA/CD is greater than that of pure or  This differs from Pure ALOHA, where stations can transmit at any time, leading to a higher probability of overlapping transmissions and thus more frequent collisions2025917—It is an enhancement over pure (unslotted) ALOHA to improve efficiency by dividing time into discrete slots.
