CLASSIFICATION BY TYPE OF DATA HANDLED

There are essentially two different types of computer processing. Each is made possible by a different kind of circuitry , and each is suitable for different purposes.

1. Analog Computers = The name analog comes from the word "analogous", meaning similar. Analog computers are used for scientific, engineering, and process control purposes. Because they deal with quantities that are continuously variable., they give only approximate results. This types of computer provides an analog or simulation of the object or system it represents. It is especially useful for solving problems that involve relationships between variable quantities in systems that change with time. The analog compute may express changing relationships in output in the form of graphs. It is able to create such pictures because it responds to changes in electrical voltages that match changes in variable quantities.

2. Digital Computers = Is a machine the specializes in counting. It operates by counting values that are discrete, or separate and distinct, unlike the continuous quantities that can be measured by the analog computer. Digital Computers are used for both business data processing and accuracy. The basic operation performed by a digital computer is addition. It can store the sums of addition problems as they accumulate, and can complete a single calculation in a fraction of a nanosecond. The digital computer is capable of storing data as long as needed, performing logical operations, editing input data, and printing out the results of its processing at hight speed.

3. Hybrid Computers= Although both analog and digital computers are extremely used in widely accepted in various industries, manufacturers have to attempted to designed a computer that combines the best features of both types. This special-purpose machine called a hybrid, computer, combines the measuring capabilities of the analog computer and the logical and control capabilities of the digital computer. It offers an efficient and economical method of working out special types of problems in science and various areas of engineering. Some Hybrid machines contain special equipment to convert analog voltages into digital voltages,and vice-versa.
