Hi All,
I have couple of conceptual questions.
1) When we talk about paging in Operating system or Computer Architecture,page size is always in power of 2.Why is it so ?
2) When we have external fragmentation,in order to combine all free space together we do compressing i.e merge all holes of main mamory together.
What disadvantages do we have by doing compression.Ofcourse one could be it will make speed slow of other running processes.What other disadvantages we will have becuase of compression?
Thanks in advance.
