History Of Computer

The history of computers dates back to the 20th century when mechanical devices such as

the Analytical Engine envisioned by Charles Babbage laid the foundation for modern 

computing. However, it was the development of electronic computers in the mid-20th century that revolutionized the world of computing. From the cell phone to today’s smartphones, computers have undergone a dramatic evolution, becoming faster, smarter, 

smaller and more powerful with each passing year.

Abacus

The history of computers begins with the birth of the abacus which is said to be the first computer. It is said that the Chinese invented the Abacus 4000 years ago.

It was a wooden rack-like instrument with metal rods on which beads were attached. The beads were moved by the abacus operator to perform mathematical calculations according to certain rules. Abacus is still used in some countries such as China, Russia, and Japan. An image of this tool is shown below.

Napier’s Bones

John Napier was the richest Scottish politician who studied mathematics. He was particularly interested in devising computational support methods. His greatest effort was the invention of logarithms. He wrote the logarithmic measure on a set of 10 wooden bars and was thus able to multiply and divide by combining the numbers on the bars. which later became known as Napier’s Bones.

Pascaline

Pascaline is called a mathematical machine. It was invented between 1642 and 1644 by a French mathematician, Bias Pascal. It is believed to be the first electrical and automatic calculator.

Pascal invented this machine to help his father, who was a tax accountant. This machine could only perform addition and subtraction. It was a wooden box with a series of gears and wheels. When one wheel is rotated in one revolution, it rotates the neighboring wheel. A series of windows are provided on the top of the wheels to read the total. 

Gottfried Wilhelm Leibnitz in 1673 

In 1673, a German mathematician Gottfried Wilhelm Leibnitz developed this machine. He improved Pascal’s invention to develop this machine. It was a digital mechanical calculator that could add and subtract like Pascal’s machine, but it could also multiply and divide. It was called a stepped calculator because it was made of fluted drums instead of gears.

Automatic differential engine

In the early 1820s, Charles Babbage was considered the father of the modern computer (although none of his computers worked or were fully built). He developed a modern design. It was a mechanical computer that could do simple calculations. It was a steam-powered calculating machine designed to solve tables of numbers such as logarithm tables.

Analytical Engine

Also in 1830, Charles Babbage developed a calculating machine. It was a mechanical computer that used punch cards as input and was capable of solving any mathematical problem and storing information as permanent memory.

Tabulator 

In 1890, an American statistician, Herman Hollerith, invented this tabulator. which was based on punch cards. It could tabulate figures and record or organize data or information. This machine was used in the 1890 US Census. Hollerith also started Hollerith’s Tabulating Machine Company, which later became International Business Machines (IBM) in 1924.

Atanasoff-Berry Computer  

It was the first electronic computer introduced in 1930. Dr. John Vincent Atanasoff and his assistant, Clifford Berry, built the first truly electronic computer, called the Atanasoff-Berry Computer or ABC. Atanasoff said that the computer used a circuit with 45 vacuum tubes for calculations and capacitors for storage. It was also the first computer to use binary arithmetic. It could do 25 calculations in a few minutes.

Automatic Sequence-Controlled Calculator

In 1944, Dr. Howard Aiken completed the construction of an automatic sequence-controlled calculator, which became known as the Mark I. It had over 3000 mechanical relays and was the first electromechanical computer capable of making logical decisions.

Electronic Numerical Integrator and Computer(ENIAC)

The first all-electronic computer was the electrical numerical integrator and calculator known as ENIAC. It was designed by J. Prosper Eckert and John W. Mauchly. The ENIAC was the first multi-purpose electronic computer, although reprogramming was very difficult. It was primarily used to computerize aircraft courses, shell trajectories, and break codes during World War II
