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...

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.
Which access method is used by Ethernet?

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.
What is a non persistent pollutant?

How do persistent and non-persistent pesticides differ?
Non-persistent pesticides are compounds that break down quickly in the environment. Several different classes of pesticides make up this group: • Cholinesterase-inhibiting pesticides, which includes the organophosphates and carbamates • Chlorinated phenols • Herbicides • Pyrethroids • Fungicides • Repellents Non-persistent pesticides became widely used after persistent organochlorine pesticides were banned from manufacture and use in the United States in the 1970s. Non-persistent pesticides are less harmful to the environment because they do not build up but they have to be applied more often to households and crops to be effective.
What are some differences between persistent and non persistent pollutants?
Persistant breaks down slowly is easy to die down. non-persitant breaks down fast and is hard to get rid of.
