when the station is having a frame to be transmitted it first checks whether the channel is busy. if the channel is busy it backs off for a fixed amount of time and checks the channel again and if the channel is free it transmit the frame otherwise it again goes to the waiting state for some random period of time...

Distinguish between persistent and non persistent CSMA?

Pesistentent CSMA sense the channel continuously where as non pesistent CSMA resense the channel after a time decided randomly or based on probabilistic work----- Sanjay Bhaumick


Difference between non-persistent and p-persistent csma?

Non-persistent is deferential, while 1-prisistent is selfish.In non-persistent CSMA if the medium is busy, there will be a random delay for retransmission. This reduces the probability of collisions, but wastes the capacity.In 1-persistent CSMA if the medium is busy, the channel will be sensed until it is idle, then it will transmit immediately. This means that collisions are almost guaranteed to occur.

Why are non-persistent pesticides more dangerous than persistent pesticides?

Non-persistent and persistent pesticides are equally dangerous, but non-persistent has immediate impacts whereas persistent pesticides wield long-term effects.Specifically, non-persistent pesticides include the super-powerful organophosphate malathion. They may impact people and wildlife for hours to weeks until they degenerate. In contrast, chlorinated hydrocarbons represent prime examples of persistent pesticides which survive for months to decades in the environment.It is the difference between immediate, sudden death or disability and long-term, protracted fatalities.


How do persistent and non-persistent pesticides differ?

Persistent pesticides remain in the environment for a long time without breaking down, leading to potential accumulation in soil and water. Non-persistent pesticides break down more quickly and have shorter residual effects in the environment, which can reduce long-term impacts on ecosystems and non-target organisms.


What are some differences between persistent and non persistent pollutants?

Persistent pollutants remain in the environment for long periods of time, accumulating in living organisms and causing harm over time. In contrast, non-persistent pollutants break down relatively quickly in the environment and do not bioaccumulate to the same extent. Persistent pollutants can have long-term effects on ecosystems and human health, while non-persistent pollutants tend to have more immediate and local impacts.


Persistent and non persistent pesticides differ?

Persistant pesticides last longer than non persistant pesticides. This means that they can build up in animals and humans and cause more damage.


What is a non persistent pollutant?

A non-persistent pollutant is a type of pollutant that breaks down relatively quickly in the environment, usually over a matter of days to weeks. These pollutants do not accumulate in the environment or in living organisms to the same extent as persistent pollutants.
