Types of Computer

Analog computer: - An analog computer must be able to accept inputs which vary with respect to time and directly apply these inputs to various devices.

Used for - 

  1. Measuring temperature pressure etc.
  2. Communication.
  3. Broadcast transmission.

Examples - Automobile speedometer, voltmeter etc.

Digital computer: -They represent information discretely and use a binary (two step0 system that represents each piece of information as a series of zeroes and ones.

 Used for –

  1. Mathematical calculations.
  2. Compare values.
  3. Storing the results.

Examples – Digital watch.

Hybrid computer: -These are machines that can work as both analog and digital computers.                    

Examples – STD\PCO0 phone, where one communicate with a person using analog computer and the rate as charges and pulse rate is measured in forms of digit. Measuring heart beat or ECG system in ICU in a hospital.

Another manual calculating devices was john nophier bone. Charles Babbage a nineteenth century professor at Cambridge University is considered to be the father of modern digital computer. Babbage designed a different engine in the year 1882 which could produce reliable tables. In 1842 Babbage comes out with his new idea of analytical engine that was intended to be completely automatic. It was capable of performing the basic arithmetic function for any mathematical problems and it was to do so at an average speed of 60 additions per minutes. It was very complex in design and huge in size. It used over 3000 electricity actuated switches to control its operation and was capable of performing was approximately 50 feet long and 8 feet high. It was five basic arithmetic operation additions, subtraction, m...
