supporting hundreds, or even
thousands, of users simultaneously.

Super computers

These are the fastest type of computers.
Supercomputers are very expensive and are
employed for specialized applications that require
immense amounts of mathematical calculations.
For example, weather forecasting requires a
supercomputer. Other uses of supercomputers
include animated graphics, fluid dynamic
calculations, nuclear energy research, and
petroleum exploration.

Embedded computers

An embedded computer is designed for and built
into a specific application where it will perform a
limited range of dedicated functions. The size
and functionality of an embedded
computer depends on the application. They may
be very small devices built into a single
