Computer Organization and Operating Systems

Computer Organization and Operating Systems
Summary
The study takes a look at the types of architecture by which modern
processors are made.
The layout of CPUs based on each architecture type gets discussed
by the study.
The study conducts a detailed analysis of hypervisor-based and
container-based virtualization with Windows and alternate
operating systems.
Advantages
CPUs based on the Harvard architecture can execute programs
much faster.
CPUs based on Von Neumann architecture can store both
instruction and data programs in same memory block.
Virtualization can significantly reduce expenses of a company.
Disadvantages
CPUs based on the Harvard architecture is not widely used.
In CPUs of Von Neumann architecture defective programs can
override other programs leading to crashes.
Virtualized environment can be incompatible with several
applications.

In conclusion the study successfully illustrates how CPU circuits
are formed.
It also shows how hardware environments can be virtually
emulated by using complex CPU instructions.
