6. BASED ON APPLICATION:
Analog
computer: It worked on quantity in
a continuous signal form like Patrol pump,
weather forecasting, temperature etc.
7. DIGITAL COMPUTER
It works on 0 and 1.
It gives accurate result because this computer
uses digital signals.
Hybrid Computer: Combination of analog
and digital computer. It convert digital to analog
and vise versa.
