History of computer 


History of the computer began with primitive design  in the early 19 the century and went on to change the world during 20 century .




The history of computers goes back over 200 years. At first theorized by mathematicians and entrepreneurs, during the 19th century mechanical calculating machines were designed and built to solve the increasingly complex number-crunching challenges. The advancement of technology enabled ever more-complex computers by the early 20th century, and computers became larger and more powerful.
Today, computers are almost unrecognizable from designs of the 19th century, such as Charles Babbage's Analytical Engine — or even from the huge computers of the 20th century that occupied whole rooms, such as the Electronic Numerical Integrator and Calculator.  
Here's a brief history of computers, from their primitive number-crunching origins to the powerful modern-day machines that surf the Internet, run games and stream multimedia.

19 th century 



1801: Joseph Marie Jacquard, a French merchant and inventor invents a loom that uses punched wooden cards to automatically weave fabric designs. Early computers would use similar punch cards.

1821: English mathematician Charles Babbage conceives of a steam-driven calculating machine that would be able to compute tables of numbers. Funded by the British government, the project, called the "Difference Engine" fails due to the lack of technology at the time, according to the University of Minnesota

1848: Ada Lovelace, an English mathematician and the daughter of poet Lord Byron, wrote the world's first computer program. According to Anna Siffert, a professor of theoretical mathematics at the University of Münster in Germany, Lovelace wrote the first program while translating a paper on Babbage's Analytical Engine from French into English. "She also provides her own comments on the text. Her annotations, simply called "notes," turn out to be three times as long as the actual transcript," Siffert wrote in an article for The Max Planck Society. "Lovelace also adds a step-by-step description for computation of Bernoulli numbers with Babbage's machine — basically an algorithm — which, in effect, makes her the world's first computer programmer." Bernoulli numbers are a sequence of rational numbers often used in computation.









1853: Swedish inventor Per Georg Scheutz and his son Edvard design the world's first printing calculator. The machine is significant for being the first to "compute tabular differences and print the results," according to Uta C. Merzbach's book, "Georg Scheutz and the First Printing Calculator" (Smithsonian Institution Press, 1977).

1890: Herman Hollerith designs a punch-card system to help calculate the 1890 U.S. Census. The machine,  saves the government several years of calculations, and the U.S. taxpayer approximately $5 million, according to Columbia University  Hollerith later establishes a company that will eventually become International Business Machines Corporation (IBM).




Early 20th century

1931: At the Massachusetts institute of Technology ( MIT), Vannevar Bush invented  and built the Differential Analyzer, the first large-scale automatic general-purpose mechanical analog 
Computer, acccording to Stanford university. 

1936: Alan turning, a british scientist and mathematician , Presents the principle of a universal machine, later called the turning machine , in a paper called " on computable Numbers..."
according to Chris Bernhardt's book " turning's Vision " ( The MIT Press , 2017 ) . Turning machines are capable of computing anything that is computable. the central concept of the modern computer is based on his Ideas. Turning is later involed in the development of the turning-Welchman Bombe, and elctro-mechanical device designed to decipher Nazi code during world war II, according to the UK's National Museum of computing .

1939: David Packard and Bill Hewlett found the Hewlett Packard Company in Palo Alto, California. The pair decide the name of their new company by the toss of a coin, and Hewlett-Packard's first headquarters are in Packard's garage, according to MIT

1941: German inventor and engineer Konrad Zuse completes his Z3 machine, the world's earliest digital computer, according to Gerard O'Regan's book "A Brief History of Computing" (Springer, 2021). The machine was destroyed during a bombing raid on Berlin during World War II. Zuse fled the German capital after the defeat of Nazi Germany and later released the world's first commercial digital computer, the Z4, in 1950, according to O'Regan. 

1941: Atanasoff and his graduate student, Clifford Berry, design the first digital electronic computer in the U.S., called the Atanasoff-Berry Computer (ABC). This marks the first time a computer is able to store information on its main memory, and is capable of performing one operation every 15 seconds, according to the book "Birthing the Computer" (Cambridge Scholars Publishing, 2016)

1945: Two professors at the University of Pennsylvania, John Mauchly and J. Presper Eckert, designed and built the Electronic Numerical Integrator and Calculator (ENIAC). The machine is the first "automatic, general-purpose, electronic, decimal, digital computer," according to Edwin D. Reilly's book "Milestones in Computer Science and Information Technology" (Greenwood Press, 2003). 

1939: David Packard and Bill Hewlett found the Hewlett Packard Company in Palo Alto, California. The pair decide the name of their new company by the toss of a coin, and Hewlett-Packard's first headquarters are in Packard's garage, according to MIT

Reilly's book "Milestones in Computer Science and Information Technology" (Greenwood Press, 2003). 

1946: Mauchly and Presper leave the University of Pennsylvania and receive funding from the Census Bureau to build the UNIVAC, the first commercial computer for business and government applications.

1947: William Shockley, John Bardeen and Walter Brattain of Bell Laboratories invent the transistor. They discover how to make an electric switch with solid materials and without the need for a vacuum.







1949: A team at the University of Cambridge develops the Electronic Delay Storage Automatic Calculator (EDSAC), "the first practical stored-program computer," according to O'Regan. "EDSAC ran its first program in May 1949 when it calculated a table of squares and a list of prime numbers," O'Regan wrote. In November 1949, scientists with the Council of Scientific and Industrial Research (CSIR), now called CSIRO, build Australia's first digital computer called the Council for Scientific and Industrial Research Automatic Computer (CSIRAC). CSIRAC is the first digital computer in the world to play music, according to O'Regan.

Amazing calculators  before computers 

Abacus 2700 AC



Abacus  2700 ac

Abacus is a manual aid to calculating that consists of beads or Disks that can be moved up and down on a series of sticks or strings withing a usually wooden frame. 
The abacus itself doesn't calculate, it's simply a device for helping a human being to calculate by remembering what has been counted . The modern Chinese abacus, Which is still widely used in China and other countries, date from about 1200 A.D. 
It is possible that it derives from the earlier counting board is used around the Mediterranean as early as 300 B.C. An Aztec version a an abacus , Circa 900-1000
A.D, is made from Maize ( corn) threaded through strings mounted in a wooden frame.

Pascal calculator 1652 




the Pascaline or Pascal calculator  was invented by blaise pascal in 1652 to help his father . 

a tax collector in his calculating labour . 
Machine can add and subtract directly and multiply and divide directly . 

Pascal created 50 prototypes before making  this machine public 1952. 
He made numerous revision of this machine. 
Only nine machine survived in the time. Most of them are in Museum in Egypt. 

Stepped Reckenor 1964 





Stepped Reckenor was invented Gotfried Leibniz . It was the first  Machine calculate all four arithmetic  operation . it was the only machine which use cursor. 
Therefore I have memory for storing operand. 
Leibniz built two stepped recknor. one in 1694 and second in 1706 . The second one was forgotten at  attic university of  Gotfried Leibniz discovered 250 year later . 

Arithmometer 1820 

Arithmometer 1820 was patented by Thomas De Colmar in 18 50  and  was first machine to  to used in offices from 1850 1890. The Arithmometer was the first machine only used in production 
The machine can perform addition subtraction directly and can perform long multiplication and division . 





Comptometer 1887 and Comptograph 1889


Comptometer was the first machine calculator with keyboard. 


The keyboard consist of 8 column of 9 keys.  the Comptometer was very similar to  Pascaline and can perform faster calculation due to its keyboard.
And it can perform long multiplication and division. Some Comptometer have  keys for  special purpose su ch as currency and weight. 

Comptograph is improved version of Comptometer with printing mechanism. 

Despite its improvement.  it is very complicated to use and therefore  slower .





Difference Engine 1822


Difference Engine was invented by charlies Babbage in 1822. 



It  would have been  the first machine capable of calculating and holding 7 numbers with 31 digits  each and automatically used results from previous operation as input. 
it was designed to tabulate polynomial  function. 
the project was never completed and abandoned in 18 34. 

Analytic Engine 

after abandoning the Difference Engine . Babbage started  to work on analytic engine. the Ancestor of modern computer. The computer has two separate input stream . 
Three output results. 
Processing unit and memory . 
it was the first  machine have programming set of instruction. 
it was Lady Ada Love Lovelace . 
Who wrote alogritham to compute Bernoulli numbers the first program  ever created . 
Hence earning her to be first computer programmer.  Babbage was not able to complete analytic engine
due to inadequate funding . 


9. Millionaire 1893

The millionaire was the first calculating machine . 
that can perform direct multiplication unlike its predecessor . 

where multiplication was performed as repeated addition . 
the millionaire required only one turn of crack and handle to multipy and entered numbers by a multiply .
