What Is Computer
A computer is a device that can be instructed to carry out
an arbitrary set of arithmetic or logical operations automatically. The
ability of computers to follow a sequence of operations, called a
program, make computers very flexible and useful. Such computers are
used as control systems for a very wide variety of industrial and
consumer devices. This includes simple special purpose devices like
microwave ovens and remote controls, factory devices such as industrial
robots and computer assisted design, but also in general purpose devices
like personal computers and mobile devices such as smartphones. The
Internet is run on computers and it connects millions of other
computers.
