A Brief History of Computers is long back. The Development of computers started ages ago, computer scientists and researchers built a modern computer to make the task of calculation as easy as it can be.
In the early days people or individuals exchanged goods [Barter System] during the process of exchanging goods, they felt to count and tally them.
So they used and utilized stones or wooden sticks to count, to make it simple and easy before purchasing or buying goods from others.
Slowly and gradually the general population of that age started drawing a line on the sand for the purpose of counting the goods,
It was a tedious process as when the counting number grew lengthy it was very difficult to collect the information on sell and purchase so they stopped.

The Invention of Abacus
The abacus was designed and invented in 3000 BC by the Chinese and later it was modified and changed.
The abacus or a math device was a wooden frame with 9 bars vertically and 1 pole horizontally, each pole bears around 7 beads.
The bar was partitioned into 2 portions upper and lower the upper portion consisted 2 beads and the lower portion consisted of 5 beads.
The upper portion with 2 beads was represented as the number 5, and the lower portion with 5 beads was a single unit or solitary unit.
Users used to move the bead from one end to another and the outcome was displayed in the center or focal point of the wooden frame.
People or individuals used to do operations such as addition and subtraction utilizing the beads and their positions.
The abacus or math device is still widely used in some parts of Asia to count, tally, and calculate.
John Napier | Napier Bones
In 1617 A scientist and researcher named John Napier from Scotland invented and developed logarithms.
The machine he invented used to calculate multiplication via performing addition and expansion.
The machine utilized the arrangement of bars and these bars contained digits from 0 to 9.
Which were numbered and were made of bones in this way called Napier’s bones and later John Napier’s development drove straightforwardly to slide rule.
Leonardo da Vinci (1452-1519):: made drawings and illustrations of gear machines but he never built or manufactured any.
Blaise Pascal | Pascaline
In 1962 A celebrated and well-known French mathematician Blaise Pascal at 19 years old developed the main mechanical computing and calculating machine known as “pascaline“.
The machine had a number of teeth and wheels associated with chains. There were 2 models one was 6 wheels and the other was 8 wheels
The individuals couldn’t stand to buy 6-wheel machines as they were truly costly. The number was entered into the machine by dialling on the wheels.
As the full turn of the principal wheel was finished it augmented the second wheel. The machine or device was essentially utilized for Addition and multiplication.
1617 Ad Gottfried Leibniz rolled out further valuable improvements in Blaise Pascal’s Machine.
This German researcher assembled a machine that can do all four operations (Addition, Subtraction, multiplication, and Division) and named it a stepped reckoned.
He was the person who supported the utilization of the binary number system which is currently crucial and fundamental to advanced modern-day computers.

Differential Engine | Charles Babbage
1822: English mathematician and scientist Charles Babbage invented the machine named ” Differential Engine”.
Later Babbage also invented the machine an Automatic computing mechanism and named it “Analytical Engine”.
The Analytical engine was able to store the information and data in its own memory.
This was the crucial and fundamental development of modern-day machines that utilized the essential and basic principle proposed by Charles Babbage.
This was a significant advancement in the field of all computer generation, all modern-day computers today utilize a similar idea.
His development is considered a real achievement in the history of computers. Consequently, he is called the “Father of Computers” and his commitment to this field is a breakthrough and a milestone.
A Brief History of Computers
Hollerith 1890 Census Tabulator
Herman Hollerith a German mathematician created and invented the tabulating machine utilizing punch cards for registration in the USA,
The cards used to have gaps when the cards went through machines the machine distinguished the gaps and afterwards the machine could recognize the numbers and later the machine could make important calculations
Second World War Computers During the Second World War numerous nations were fabricating and building new outlines and new designs for Aircraft,
Modern computers were utilized as a part of mystery military operations, and with the help of cutting-edge machines, they were decoding the messages.
In this war PC’s assistance and help were unfathomable in illuminating numerous repetitive and tedious issues that only they could explain,
The computers that were utilized as a part of the war were named Z1 and Z2 Computers German build Konrad Zuse (1910– 1995) built his PC Z1 to Z4 impacted the Second World War.

IBM’s Harvard Mark 1
The Harvard Mark I and the ENIAC are both Historical Computers that have implied an incredible arrangement to the advancement in the field of current PC history.
It was the first generation of computers and was called an Automatic Sequence Controlled Computer (ASCC).
They used to perform Addition and increase electromagnetically With no human exertion.
It used to perform three augmentations and one subtraction in 1 second and one increased operation in 1 second ENIAC
Electronic Numerical Integrator and Computer was the principal electronic universally useful computer.
It was a machine that could explain an extensive number of numerical operations with reconstruction.
ENIAC was not ready to store the information or direction it was just created to perform huge numerical calculations.
In 1946, John Mauchly and John Presper Eckert built the ENIAC I (Electrical Numerical Integrator And Calculator).
Their examination was broadly supported by the American military.
The American armed forces required a PC for unraveling mounted guns shooting table which was utilized to set distinctive weapons under any condition for target accuracy
Howard Aiken and Grace Hopper planned and built up the MARK arrangement of PCs at Harvard University.
The arrangement started with Mark-I in 1944.
The machine they assembled was an immense PC you can envision it was 55 feet long and 8 feet high it required a gigantic room or space for convenience it was around 5 tons, and it contained around 7,60,000 pieces.
These sorts of computers were utilized by the US naval force for gunnery and ballistic Calculation.
Vacuum Tubes – 1930 – 1950s
The First Generation Electronic Computers utilized vacuum tubes, vacuum tubes are glass tubes with circuits inside.
Vacuum tubes have no air within them which secures the circuitry
The UNIVAC 1951
The UNIVAC I (Universal Automatic Computer I) was the principal business PC created in the United States.
It was outlined by J. Presper Eckert and John Mauchly, the designers of the ENIAC it was the real disclosure ever.
