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.

Consider the delay of pure aloha versus slotted aloha at low load which one is less?

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.


Difference between simple shear strain and pure shear strain of fabric?

Simple shear strain involves deformation by parallel sliding of fabric layers in opposite directions, resulting in stretching and compressing of the material. Pure shear strain occurs when fabric layers are displaced in opposite directions, causing the material to deform by shear without any change in volume. In simple shear, there is both shearing and stretching/compressing, while in pure shear, only shearing occurs.


What is the difference between pearlite and ferrite?

Pearlite is a layered structure of ferrite and cementite formed by the eutectoid reaction in steel, while ferrite is a pure form of iron in its BCC crystal structure. Ferrite is soft and ductile, while pearlite is harder due to the presence of cementite.


What is the difference Celsius degree and degree Celsius?

Well, darling, the only difference between "Celsius degree" and "degree Celsius" is the order of the words. It's like asking what's the difference between "chicken fried rice" and "fried chicken rice." They both refer to the same thing - a unit of temperature measurement on the Celsius scale. So, whether you say "Celsius degree" or "degree Celsius," you're still talking about how hot or cold it is outside.


What is the THC levels of pure power plant?

Pure Power Plant typically has a THC level between 15-21%. However, THC levels can vary depending on growing conditions and cultivation techniques used by the producer.

What are the difference between pure aloha slotted aloha?

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.

IN networking Slotted aloha is a improved version on aloha protocol On what factors the improvement is implemented in slotted 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

Compare pure aloha and slotted aloha?

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.

The difference between a homogeneous mixture and a pure substance is that a pure substance has a fixed composition and cannot be separated because it is chemically bonded and a homogeneous mixture can be separated.
