 Use of different types of digital computers
 Application of different types of digital computers.

Analog Computer
 The computer which provide us
information in continuous form are
called analog computer.
 Analog computer represent
physical quantities such as
voltage, pressure, speed and
temperature.
 Its output is usually displayed on a
graphs or dials.

There are following characteristics of analog
computer.
 Speed.
 Calculate physical quantities.
 Result not reliable.
 Give output in the form of graphs on dials.
 Continuity in working
 Fewer function.
Characteristics of the Analog Computer

Characteristics of the Analog Computer

Uses:-
 Used in engineering & Science,
 Used to calculate analog quantities.
Example:-
Thermometer, Speedo meter etc .

 A digital computer work
with digits.
 Everything is described in two states i.e.
either on or off .
 The number 1 represents on & 0
represents the off states.
 Give output in digital form.
Digital Computer

These characteristics are following below
 Speed.
 Big memory.
 Reliable result.
 Calculate mathematical .
 Give output in digital form.
Characteristics of The Digital Computer

Digital Computer
Uses:-
 Used in all filed of life.
 Used in all calculation of mathematically
Example:-
Score Bore, digital clock, digital
thermometer, Digital petrol pump etc.


 The computer which have
qualities of both digital &
analog computers are called
hybrid computer.
 Hybrid computer has the
speed of analog & the
accuracy of digital computer.
Hybrid Computer

There are the following characteristics of hybrid
computers.
 Reliable & Provide accurate result.
 Work fast & Speedy.
 Helpfulin hospitals.
 Givenoutput in both graphic& numeric form.
 Both qualities in these computers.
Characteristics of Hybrid Computer

Hybrid Computer
Uses:-
Used in hospital (ICU) .
Scientific laboratories .
Used in petrol pumps .
Used in industrial unit.
Example :-
ICU hospital computer .

Analog Computer :-
 Slow Speed.
 Low memory.
 No State.
 Difficult to use.
 Less reliable.
 Use in Engineering &
Science.
e.g. Analog Clock ,&
thermometer etc .
Digital Computer :-
 Fast speed.
 Big memory.
 Two State.
 Easy to use.
 More reliable.
 Use in all field of life.
 e.g. Digital Laptop &
Digital Camera etc .
