The Core of Slotted ALOHA

At its heart, Slotted ALOHA is a random access protocol designed to manage channel access in a shared networkQ1 True or False Unlike its predecessor, pure ALOHA, Slotted ALOHA divides time into discrete, equal-sized slotsNon-Colliding First Messages in Slotted ALOHA All participating nodes synchronize to these slots, and a node can only attempt to transmit at the beginning of a slotProbabilityof A winning the 2ndback off race = 5 / 8 = 0.625.
