Types of computer

These are three types of computer:

 Analog computer's:

 .Digital Computer's .Hybrid Computers Analog Computers analogue computers used electronic or mechanical for Neymar to model in the problem being sold by using one kind of physical quantity to spend it another the analogue computer Excel is in solving dynamic problem and simulating complex physical system it has no way for men machine in tractor recording and graphic display high speed computer in elements used to simulate mathematical function physical system and dynamic process or arrange in as much the same person as the physical system they represent. early special purpose analogue computers were the side rule the server middle and plain mean and harmonic analysis in word word to analogue computer in mechanics war of great importance of gunfire control on worship general purpose analogue computer were first Bullet in 1930.

 Digital Computers

digital computer process data in numerical form using digital circuit the digital computer perform arithmetic and logic operations which discrete value digital computer are good at solving algebraic equation and even better at Manipulating numbers. it is unbeatable for high speed visheshan in Arithmetic operations data storage and documentation it can be performed only calculation at a time. the result can be obtained in a variety of form such as printed table magnetic type and the familiar punched card while properly used in higher query high-volume numerical calculation the digital computer are extremely good in early 1940s, Aiken built the digital general-purpose digital computer called Mark 1 with the invention of digital computers a new age of computing started. today digital computers are widely being used in business Educational Institute Hospital etc for various purpose sample of digital computers IBM PC Apple Macintosh computers etc.

 Hybrid Computers

 hybrid computers are the combination of analogue and digital computers hybrid computers use analogue to digital some of the  conversion at digital to analogue conversation and main input or output other analogue or digital data. dynamic problems that runs took too long oval too difficult to handle can be solved in a responsible period of time these computers can be produced highly at chacu date to resize result these types of computer are used in Robotics medical labs etc.

Classification of Computer.

computer come in many different sizes and ranges of power and different types of computer systems have varying capabilities.Today computer system are classified into following categories.

Super Computer.

Mainframecomputer.

 Mini Computer.

 Micro Computer.

SuperComputer:

Supercomputers are the most powerful computers made physically they are some of the largest.these systems are bulit to process huge amount of data and the fatest computers can perform more then 1 trillion calculation per second

History of Computer

Today you can find computer almost everywhere microwave ovens automobiles their more states and even wrist watches contain computer chips. In fact computer are so common in modern society that everyone is affected by Computer technology to some extent a computer is an electronic device that process data and converts it into information computer and programs which process data and perform task based on the instructions contained in the program because a computer program can ever youth data and then based on those evolution results are are generated which can be used for large number of applications computer can process data with little assistance some example for computer applications are
 controlling space flight
landing airplanes
 tracking inventory
 painting books
 turning on light at the specified time
 check out groceries at checkout counter in this chapter we will explore the history of computer and define the different types of computer available today also the impact of computer on society will be discussed along with the introduction to program languages.

 *History of computer*

 the history of the computer start out about 5000 years ago with the birth of the abuse it is and wooden rack holding horizontal wires with beads strings on them when these days I moved around according to programming rules the moral side by the user or regular airthmetic problems can be done.

 *Napier,s Bones* 

John niper a score chess match medical create logarithm tables abilities calculations he also create a device using roads also called nai papons to perform arithmetic calculation these rods were widely used by accountants and bookkeepers Saral peoples used the concept of the logarithm to develop the side roles with the modern slide rules you could not only performed the arithmetic operations but also calculate squares and square roots log sin sin and tangent slide Rose was used in the middle 70.

*Pascal's pascaline Calculator*

 Pascal invented a machine that had a system of there's a one tooth gear in gauges IT single tooth with the 10 tooth gear once every time it revolves it must make 10 revolutions to rotate the 10 get 1 once number could be entered the community sons obtained by cranking a handle. Pascal calculator was not a commercial success because the device is could not be bullet with sufficient appreciations for practical use. German mathematician want live in is produced a machine that was similar to pascal but more reliable and accurate other mechanical calculator followed that were refinements on the design and pascal and Leibniz.

 *Charles Babbage*

 Thomas of Colmar was developing the calculated a series of very interesting government in computer was started in Cambridge England by Charles machine calculating machine which he called a difference engine by 1822 he had a working model to demonstrate.it it was intended to be a steam powered and fully automatic including the printing of the result.Babbage continued to work on it for the next 10 years but in 1833. he lost interest because he proposed fully program controlled automatic mechanical digital computer.Babbage debit card this idea and analytical engine the idea of this design showed a lot of food for site also this could not be appreciated until a full century letter the machine was supposed to operate automatically the steam power and require only one person.

Use of punched cards by Hollerith. In 1890 Herman Hollerith developed the first electromechanical punched card tabula trick or treat information that had been put into card these card form and maintained in state farm solutions to different problems could be stored on different types of card and except when needed invention of punched cards open a get a modern data process IBM and other computer manufacturers came for work and started production of punched card using computer this computer could add multiply and short members that our fat and result for processed on punched cards As compared to today's mechanics this computer was low usually processing 15 to 20 cars per minute is card holding about 18 decimal numbers practice at that time however punched card for a hug step forward they provided a means for input output and memory storage on a scale.

 Electronic Digital Computers

 The start of World War II produced in large need of computer the plastic specially for the military new weapons were made for which large number of calculation was needed In 1942 Jahan Pe acadzone match Lay and Associates at the Maurya School of electrical engineering university of panel a senior decide to build a high speed electronic computer to do the job this machine was Know as electronic numerical integrator and calculator. 

 The Modern Stored Program EDC

 Fascinated by the success of the mathmatic John Von Newman in 1945 undertook a study of competition that show that a computer should have a very simple fix physical structure and yet be able to perform any kind of computation with the need of any physical change in its unit 11 contribution a new Awareness of a practical and fast computer should be Bullet these id I usually referred to a store today program technique become essential for future generation of high speed digital computer and where University adopted according to one month free data and program can be stored in the same memory the machine can itself ulta Adil its program of international data as a result of these Idea computing of program become much faster more flexible and efficient.
