An ethernet-like protocol that permits all earth stations in one network to share a pool of inbound bandwidth.
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
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 4) In slotted ALOHA, a frame can be sent only at fixed times, whereas in pure ALOHA, you can send any 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.
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
in terms of collision that is there was less collision rate in pure aloha the percentage of transmission was abt 19 % and in case of sorted it was doubled that is 38% you can wiki for more information..!! -prajmunti
Pure ALOHA uses a very simple idea that is to let users transmit whenever they have data to send. Pure ALOHA is featured with the feedback property that enables it to listen to the channel and finds out whether the frame was destroyed. Feedback is immediate in LANs but there is a delay of 270 msec in the satellite transmission. It requires acknowledgment if listening to the channel is not possible due to some reason. It can provide a channel utilization of 18 percent that is not appealing but it gives the advantage of transmitting any time. Slotted ALOHA divides time into discrete intervals and each interval corresponds to a frame of data. It requires users to agree on slot boundaries. It does not allow a system to transmit any time. Instead the system has to wait for the beginning if the next slot.
Aloha aloha aloha
"Aloha nui aloha" is a Hawaiian phrase that translates to "love is all around" or "love and affection." It is a way to express deep love and affection towards someone.
aloha po or aloha aumoe (if going to bed) [aloha po] [aloha ow-mo-ay]
Answer: Aloha oe pilialoha [aloha oy pee-lee-aloha], or Aloha Huakaʻi pilialoha [aloha hoo-ah-ka-ee pee-lee-aloha] (I like this one).
