8. Recent Inventions – Cloud Computing
It is a term used to describe technology that will
replace how we currently use our computer and
software applications.
It allows users to have access to applications
that they would not have. Access is as simple
as using an interface application or just a web
browser from any location.
It allows users to work from anywhere, to
perform any task with any application, and to
pay for only what you use.

13. CONCLUSION
Information flow is what the Internet is about.
Information sharing is power. If you don't
share your ideas, smart people can't do
anything about them, and you'll remain
anonymous and powerless.
