2. Computer Class by Operating
Principle
Computers can be divided into three
basic categories based on the
Operating principle :
1-Analog Computer
2-Digital Computer
3-Hybrid Computer
3. Analog Computer
The computer which provide us
continuous information are called
Analog computers.
Speed
The input data is not a number infect
a physical quantity like: pressure,
speed, voltage, temperature
5. Digital computer
The computers which present physical
quantities with the help of symbols or
numbers and provide us discrete
information are called digital
computers.
Digital computer the input data is
represented by a number, a computer
that processes information in digital
form.
Accuracy
7. HYBRID COMPUTER
Hybrid computers are computers
that exhibit features of both analog
computers and digital computers.
Hybrid computer has the speed of
analog and the accuracy of digital
computer.
