The word computer,
in its most general sense,
can refer to any device
used to perform calculations automatically.
definition
We normally think of a computer
as an electronic device which carries out
tasks or calculations
by following a precise series of instructions
called a 'program'. A computer is a combination
of hardware and software.

Personal Computer (PC)
The most common type of computer,
called the 'personal computer (PC)',
is designed to be used by one person at a time.
The PC has developed into
a number of different forms.
Embedded Computers
mainframe computer
Embedded computers are microchips
found inside a variety
of machinery and equipment,
including pocket calculators,
car engines and video-game consoles. They are pre-programmed
to carry out a very specific,
limited number of tasks.
Mainframes are large powerful
'supercomputers' with thousands
of linked microprocessors.Used by governments and research
institutions to carry out
highly complex calculations.
