Classification of computer by data processed

According to internal processing computers can be classified into three main types namely digital computers, analog computers and hybrid computers. 1. ... A digital computer represents data in the form of discrete numbers and processes data using the standard arithmetic operations.

2. OVERVIEW AND HISTORY Computer systems may be classified according to the data they are designed to process or they may be classified according to their size and capabilities . The data required for processing may be obtained either as a result of counting or through some measuring device . Data obtained through counting is known as discrete data, while that obtained through measuring instruments is known as continuous data .  An example of discrete data is the number of marks obtained by a student in an examination, while the constant monitoring of the Electro-Cardiogram of a patient is an example of continuous data.

4. ANALOG COMPUTER Computers that measure the continuous physical magnitude or electrical states. For example pressure, temperature, voltage, volume, etc. A speedometer in a vehicle is another example of analog computer. Analog computers are used for scientific, engineering & process control purposes. Since they deal with quantities that are continuously varying in nature, they give only approximate result i.e. Not accurate results as in digital computer.

6. DIGITAL COMPUTER computer designed to processed data in discrete numerical form which are represented by discrete signal using binary code, numbers, letters, and symbols are represented by codes based on the binary number system consisting of two digits .i.e. 1,0 the digital computer must convert all data to binary form. Generally, results from digital computer are more than the results from analog computers. They are used for counting and calculating numbers. Examples are calculator, adding machine, counting machine, etc.

9. HYBRID COMPUTER A hybrid computing system is one in which desirable characteristics of both the analog and digital computers are integrated. n an intensive care unit, analog computers may measure the patient’s heart rate, temperature, etc.  The measurements may then be converted into numbers and supplied to the digital part of the system which will thereafter regulate the flow of certain medications. They can be used for both counting and measuring. In fact, they are very useful in the control of manufacturing and processing.
