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

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.


In this earlier post, we had learned what is the computer generation and all the people of the computer generation were there for us, now in this post we have learned the history of computers if you need any information about the history of computers.
