In asymmetrical communication, downstream throughput is higher than upstream throughput.
As far as I concern, both of them are the same. Throughput rate: is the amount of data per second that can be transferred. Transmission rate: is also the amount of data that could be transmitted onto the communication link per second.

otocols used to determine who goes next on a multiaccess channel belong to a sublayer of the data link layer called MAC.Throughput and channel utilization in PURE ALOHA is 18%Throughput and channel utilization in SLOTTED ALOHA is 37% which is double of Pure Aloha
1) Pure Aloha is a Continuous time system whereas Slotted Aloha is discrete time system.2) Pure ALOHA doesn't check whether the channel is busy before transmission.Slotted ALOHA send the data at the beginning of timeslot.3) Pure aloha not divided in to time .Slotted aloha divided in to time

They differ with respect to whether time is divided into discrete slots into which all frames must fit. Pure ALOHA does not require global time synchronization; slotted ALOHA does.

At low loads, slotted ALOHA generally experiences less delay compared to pure ALOHA. This is because in slotted ALOHA, the time is divided into fixed slots, reducing the chances of collisions and improving the efficiency of the system. In contrast, pure ALOHA does not have a fixed time slot, leading to a higher probability of collisions and greater delays.
