Computers are divided into three types according to their structure, speed architecture:
The computer which provide us continuous information are called analogue computers.
Analogue computers represent physical quantities in the form of waves or in continuous form.
Thermometer is the example of analogue computer because it measures the length of a Mercury column continuously.
Traditional clock is also an example of analogue computer because the needle of clock covers the distance of dial continuously.
Weight machine and speedometer are other examples of analogue computers.
Here are some of the main characteristics of analogue computer:
The computers which present physical quantities with the help of symbols or numbers and provide us discrete information are called digital computers.
Digital watch, digital petrol stations, and the computer which we use nowadays are the examples of digital computers.
Here are some of the main characteristics of digital computers:
The computers which have qualities of both digital and analogue computers are called hybrid computers.
Hybrid computer has the speed of analogue and the accuracy of digital computer.
In ICU (Intensive Care Unit) of a hospital, hybrid computers are used. These computers analogue quality controls the temperature of the room digital quality inform the doctor about the blood pressure, temperature, and physical status of the patient.
In Cement factory a hybrid computer is used where all calculations are performed by the digital computers and actions like increase of material are performed by the analogue computers.
Here are the list of some main characteristics of hybrid computers:
