The scheduling process in the system is done by using the long-term scheduler and short-time scheduler. The long term scheduler are those which select the work from the job queue and the job selection is not very frequent.
Short-term scheduler is the scheduler that select the work from the ready queue and allocates it to the CPU(Central processing unit).It works by picking the work at quick frequency .So, it is not possible for the short-term schedulers to handle the job because of the different frequency of work.
A lossy data compression method is one where compressing a file and then decompressing it retrieves a file that may well be different to the original, but is "close enough" to be useful in some way.
