Explain enhanced second-chance algorithm, Operating System

Assignment Help:

Enhanced second-chance algorithm.

When we increase the second-chance algorithm by considering both the reference bit and the modify bit as an order pair. We have the following four possible classes.

a) (0,0) neither recently used nor modified - best page to replace.

b) (0,1) not recently used but modified - not quite as good.

c) (1,0) recently used but clean - it probably will be used again soon.
