Analog
and Digital Computer

Analog
Computer:

Analog computer is that computer,
which is use to process continuously varying data. Everything we see and hear
is change continuously. This changeable continuous stream of data is called
analog data. Analog computer can be used in scientific and industrial
applications such as measure the electrical current, frequency and resistance
of capacitor, etc.

Digital
Computer:

These are high speed electronic
devices. These devices are programmable. They process data by way of mathematical
calculations, comparison, sorting etc. They accept input and produce output as
discrete signals representing high (on) or low (off) voltage state of
electricity. Numbers, alphabets, symbols are all represented as a series of 1s
and 0s.

 Difference Between Analog and Digital Computer

Hybrid
Computer

–         
A
hybrid computer is a combination of digital and analog computers and it
combines the best features of both types of computers.

–         
For
example a petrol pump contains a processor that converts fuel flow measurement
into quantity and price.

–         
Hybrid
computer is used in hospitals to measure the heartbeat of the patient.

–         
Hybrid
computers are also used in scientific applications or in controlling industrial
processes.

–         
The
first desktop hybrid computing system was the Hycomp 250, released by Packard
Bell in 1961.
