Computer can be categorized on the basis of data handling capabilities:- ➢Analog Computer.➢Digital Computer.➢Hybrid Computer. Analog Computer:- ➢ Analog computer is a type of computer. ➢Analog computers are designed to process analogue data.➢ Analog computer works on physical quantities.Such as – density, mass, time, distance etc.➢ It gives result in signal. ➢Analogue computers directly accept the data from the measuring device without first converting it into numbers and codes. ➢It is mostly used by scientist of physics in lab.➢Examples – analytical watch, speedometer andthermometer Digital Computer:-➢Digital computer is a type of computer.➢ It is work on electronic signal (1,0 / true, false / high, low / on, off / +5,- 5 etc.) digital signal. ➢It accepts the raw data as input in the form of digits or binary numbers (0 and 1) and processes it with programs stored in its memory to produce the output➢Digital computer is most popular and common computer now these days. Hybrid Computer:- ➢Hybrid computer is a type of computer.➢ It is made by analog computer and digital computer. ➢It is fast like an analogue computer and has memory and accuracy like digital computers. ➢It can process both continuous and discrete data. ➢It accepts analogue signals and convert them into digital form before processing.➢It is mostly used in medical science.➢It is use for space technology.Examples : Petrol pump, Aeroplan, Street light, Atomic reactoretc. Types of Computer based on shape and size:- ➢Super computer➢Mainframe computer➢Mini computer➢Micro computer SUPER COMPUTER:- Supercomputers are the biggest and fastest computers. They are designed to process huge amount of data. A supercomputer can process trillions of instructions in a second. It has thousands of interconnected processors. Supercomputers are particularly used in scientific and engineering applications such as weather forecasting, scientific simulations and nuclear energy research. The first supercomputer was developed by Roger Cray in 1976. Mainframe Computer:-
