Types of Compute.

1. Analog computer 2.Digital Computer 3.Hybrid Computer.

 1. Analog computer
 Its output is usually displayed on a meter on a graph. It dose not operate with digital signals.
It has so low memory and fewer functions. It is different to operate and use.It is usually built
for special purposes.It is mainly used in engineering and medicine.
*Examples:-
1.speedometer used to measure the speed of car.
2.Analog clock measures time by the distance traveled by hands of clock around dial.
3. Thermometer is an analog device that measure the length of mercury column.

2.Digital Computer:-
A digital computer processes data in numerical form using digital circuits. It performs 
arithmetic and logic options with discrete values. These values are 0 and 1. Everything is
described in two states of ON and OFF. The digit 1 represents ON and 0 represents OFF
state.The digital computers are very fast. These computers are manufactured in a variety of
size,speeds and capacities. Digital computers are commonly used at homes and in offices etc
.APPLE MACINTOSH and IBM PC are two important digital computers.
*Examples:-
1.Digital watch displays the time that does not very continuously but changes from one
discrete value to the other.
2.Digital scoreboard directly counts discrete values such as the time left to play and the
score of each team.

3.Hybrid Computers:-
A hybrid computers is a combination o both analog and digital computers. A hybrid computer
combines the best characteristics of both the analog and digital computer. It can accept data in
analog and digital form.hybrid computer is faster then analog and digital computer very easy to
use performing well.
*Examples:-
1.Hybrid computer is a devices may calculate patient's heart function, temperature,
blood pressure etc. This measurement can be converted and displayed in digital form.
