TYPES OF COMPUTER ON BASIS OF CLASS:
There are three types of computer,
ANALOG DIGITAL HYBRID
Ø ANALOG:
Analog computers operate data by a continuous operation. e.g., speedometer
of car…
Ø HYBRID:
Hybrid computers operate data by both continuous and discrete operation…
e.g. air defense system…
Ø DIGITAL:
These computers operate data by a discrete operation…
The following computers are the examples of DIGITAL computers,
· HAND HELD COMPUTERS:
Palm Pc, Cellular Phone, 2lb, User Batteries, Transformer Pack…
