Computers became an essential part of our lives.
computer is now used in every industry. It's embedded in many devices such as your car or your washing machine.
they are used in schools and universities
some universities give their students a mobile phone (M.Learning)
embedded computers. Smart houses. smart TVs that allow you to check your e-mail while watching the show. wifi connections are used
the use of computers is increasing day by day.
pervasive computing
