In our systems memory is limited but executable programs are
infinite, so at compile time only compiler generates virtual
addresses for all executables.
While executing, memory management unit come into picture
and translates virtual addresses to physical address.
Virtual address may be same for two processes but physical
memory is unique.

Measurements of a certain system have shown that the
average process runs for a time T before blocking
on I/O. A process switch requires a time S, which is
effectively wasted (overhead). The CPU’s efficiency is
the fraction of its time its spends executing user
programs, i.e., executing user processes. For round robin
scheduling with quantum Q, give a formula for the CPU
efficiency for each of the following:
(a) Q = ∞
(b) Q > S + T
(c) S What is 32 bit operating system? Give the disadvantages of Havander's Strategies.
