Complete History of Computer

We would like to tell you that the word computer has originated from the Greek word compute which means to calculate. In the 19th century, a professor of mathematics "Charles Babbage" introduced the word computer to the world. A computer is an electronic machine. In which the computer has become a very important part of the functioning of human life in the modern environment. A particular type of software is required for the efficient operation of any computer system. We call this special type of software operating system. In which there has been a change in all the times, today we will talk about his history. That is, about the history of the computer, such as the change in many technologies in the computer, the size of the computer changed in the software of the computer in the hardware of the computer and in the ability of the computer to work. Computer have involved from huge devices that took the space of an entire room to those that can be kept on the lap while playing a video game or watching a movie. Today we will know about the same, when which computer came, according to a serial, let's come forward -

The development cycle of computer is as follows
let us take a look at the early development of computer- Abacus, Pascaline, Analytical Machine, Tabulating Machine, Mark I, abc, ENIAC, EDVAC, UNIVAC, UNIVAC III, IBM 1401, IBM 700, NCR 300 series, Burroughs B5000, and 200 series, UNIVAC 900 series, IBM 360, ICL 1900 and Burroughs 6700, Microprocessor (1970), Apple 2nd - (1977), Personal Computer.
Abacus	Abacus Image
The word abacus originated from the word abax. Whose inventor was Li Kai Chen. An abacus is made from a few beads and a wooden frame. One can quickly add or subtract any numbers using Abacus. In Abacus, each chord with its beads represents a positional number, unit's column, ten's column, etc. Beads can be used rapidly to add and subtract numbers. Multiplication can be done other than duplication. Abacus was the first mechanical calculator. It is considered a source of computer.
Napier Bones Image	Napier Bones
	A machine that simplified complex calculations of logarithms. Which was invented by John Napier in 1600 AD. Named Napier Bones, which made complex calculations easy. John Napier made many important discoveries related to numbers.
Pascaline	Pascaline  Image
Pascal is a calculating instrument. In 1642, Blaise Pascal, a mathematician from France, invented the first mechanical calculating machine. Called "Pascaline". In which a set of wheels connected by gears was used. For each position there was a wheel, a column, ten and so on, by turning the wheels, a number machine could be entered. Then, by turning the wheels again, a number can be added or subtracted beforehand. Hence, it is also called Adding Machine. When Pascal built this machine. He was 19 at the time.
Multiplying Machine	Multiplying Machine
	Gottried Leibniz of Germany made some changes to Pascal's machine. So that the machine can work better. In which multiplication and division also took place. Gottried worked closely with Sir Isaac Newton. And both of them together developed calculus calculus. Similarly, with the help of developed calculators, easily added Ghatav could be multiplied and divided. So it was a much better discovery.
Analytical Machine	Analytical Machine
Charles Babbage designed an analytical engine which was capable of my arithmetic operation instructed by punched cards, store could store numbers, compare values etc. The first female programmer, Lady Ada Augusta, created the first program in Analytical Engine, for this she is also called the world's first programmer. They are also credited with binary numbers.
Tabulating machine Image	Tabulating machine
	Herman Hollerith used information stored on punched cards to invent a tabulating machine. The tabulating machine processed stored information by mechanically reading, sorting and summing the data. Hollerith went on to found International Business Machines (IBM).
Mark I Image	Mark I
	Howard Aiken at Harvard University built the world’s first computer in 1994. It was called the Mark I or ASCC. The MARK I was an electro mechanical machine in which programs and information were input by a punched paper ribbon. However, The machine was very slow and huge.
ABC	ABC  Image
ABC is a computer invented in 1939. The inventors of ABC Computer are Jan Etanasoff and Kilford Vary. ABC Computer is the world's first electronic digital computer. The working speed of this computer was fast
ENIAC Image	ENIAC
	John Mauchly and J Presper Eckert at the university of Pennsylvania built the ENIAC for the U.S Government for  use in the second world war. ENIAC replaced the mechanical switches used were vacuum tubes. The ENIAC was much faster than the Mark I.
EDVAC	EDVAC Image
It was very difficult to change the program in an Eniac computer. To deal with this problem, Van Nuumann developed the concept and concept of idvec. Dr. Van Neumann has contributed the most to the development of modern computers, he is also credited with holding binary systems (0 and 1), both data and instructions. Full name of EDVAC ( Electronic Discrete Variable Automatic Computer)
UNIVAC	UNIVAC
Univac, an analog computer was used on television to predict the election of president Eisenhower. These computers used costly vacuum tubes, required large amounts of power, and gave off a lot of heat. Nonetheless, because of their accuracy and speed, by 1953 more than 2,000 UNIVAC were in uses.
