Who Invented The First Mechanical Computer

Who Invented The First Mechanical Computer – We can argue that the first computer was the abacus, or its descendant, the slide rule, invented by William Audret in 1622. But many consider the English mathematician Charles Babbage’s Analytical Engine to be the first modern computer.

Before Babbage, a “computer” was a person who sat around all day, adding and subtracting numbers and entering the results into a table. The tables later appeared in books so that others could use them to complete tasks such as accurately launching cannons or calculating taxes.

In fact, Babbage wrote that he was daydreaming about the logarithmic table while at Cambridge in 1812-1813, when he first imagined that a machine could do the work of a human computer. In July 1822, Babbage wrote a letter to the Royal Society proposing the idea that machines could perform calculations based on the “method of differences”. The Royal Society was interested and agreed to fund the development of the idea. The first mechanical design to emerge from these efforts was Babbage’s first differential engine.

Indeed, Babbage was first inspired by this massive number crunching project. In 1792, the French government commissioned Casper de Perroni to oversee the creation of a cadastre, a collection of logarithmic and trigonometric tables. The French wanted to standardize the country’s measurements and planned to use tables to aid in this effort to convert to the metric system. De Froni was inspired by Adam Smith’s famous work “Wealth of Nations”. Smith wrote about how the division of labor improved the efficiency of making staples. De Ferroni wanted to use the division of labor in his mathematical scheme.

Unfortunately, once the 18 volumes of tables—the second describing the mathematical process—were completed, they were never published.

Babbage visited the City of Light in 1819 and saw the unpublished manuscript page by page. He wondered if there was a way to quickly create such charts with fewer people and fewer mistakes. He considered the many wonders created by the Industrial Revolution. If creative and industrious inventors could build the cotton gin and the steam engine, why not the calculating machine?

Babbage returned to England and decided to build such a machine. His first vision was what he called a difference engine, which worked on the principle of finite differences, or complex mathematical calculations by repeated addition without using multiplication or division. In 1823 he received £1,500 from the English government and hired engineer Joseph Clement to build a different engine.

History Of Computer

Clement was a distinguished engineer and suggested improvements to Babbage, which allowed Clement to implement some of his ideas. Unfortunately, in 1833 the two disagreed over the terms of their settlement. Clement retired and finished work on the difference machine.

Developed by Charles Babbage in 1834, this analytical engine was designed to calculate any mathematical formula and had greater analytical power than its original difference engine. This part of the plant was under construction at the time of his death. SSPL/Getty Images

As Clement laid out his tools, Babbage was already thinking about a bigger idea—the Analytical Engine, a new type of mechanical computer that could perform even more complex calculations, including multiplication and division. However, the British government cut its funding, which ultimately aimed to build a different engine. Many believe that the Analytical Engine was the first computer.

The basic components of an analytical engine are the same as any computer component sold on the market today. He introduced two features of any modern machine: a central processing unit or processor and memory. Babbage, of course, did not use these terms. He called the app “Mill”. The memory was known as a “store”. It had a device – a “reader” – for inputting instructions, as well as a way to record the results produced by the machine on paper. Babbage called this output device a printer, a precursor to inkjet and laser printers.

Babbage’s new invention was entirely on paper. He kept copious notes and sketches on his computer—nearly 5,000 pages worth—and although he never built a production model of the analytical engine, he had a clear vision of how the engine would look and work. Borrowing the same technology used in the Jacquard loom developed in 1804-05, the loom, which made it possible to automatically create a variety of fabric patterns, entered data on punch cards. A computer store may have 1,000 50-digit numbers. Punched cards contain instructions that the machine can execute in sequence. A single assistant would supervise the entire operation, but the steam would operate it, turn the crank, move the cam and shaft, and turn the gears.

Unfortunately, today’s technology cannot deliver Babbage’s ambitious designs. Only in 1991 were his special ideas finally translated into a working computer. So the museum in London built its difference engine to Babbage’s exact specifications. It is 11 feet long and 7 feet high (over 3 meters long and 2 meters high), has 8,000 moving parts, and weighs 5 tons (4.5 metric tons). A copy of the machine was made and sent to the Computer History Museum in Mountain View, California, where it remained on display until December 2010. Neither device runs on desktops, but they are the first computers and precursors to the modern computer. . These computers influenced the development of the World Wide Web.

There are many differences between Babbage’s Analytical Engine and the one sitting on your desk now. These devices are mechanical and your devices are electronic. So who invented the first electronic computer? Like most inventions, the digital computer was the brainchild of many different people.

Who Invented The First Computer?

Like Babbage, Iowa State College (now Iowa State University) mathematics and physics professor Dr. John Vincent Atanasoff’s work required a lot of computing power. Although he had one of the best calculators of his time, it needed more. Time to do the math. And, like Babbage, Atanasoff wanted to see if he could do it better, and in 1937 he went for a drive to clear his mind, and when he stopped for a drink, he decided what kind of device he wanted to build. His machine would use electricity and instead of the base 10 standard, his computer would use the binary system used by our modern computers.

Iowa State provided funding for the machine, and Atanasoff enlisted an exceptionally talented graduate student, Clifford Perry, to help realize his vision. They showed the prototype to Iowa state officials, who then funded Atanasoff and Perry to build the real thing. By 1942 the Atanasoff-Perry (or ABC) computer was built

World War II led to the development of many new computers to solve specific problems. One of them was the ENIAC, which was designed to calculate artillery range tables. The other was Colossus, which was used to break German codes at Bletchley Park in England. In 1949, EDSAC made history with the world’s first practical computer with stored programs. Unlike earlier computers designed to perform a specific task, the EDSAC can perform multiple tasks. In the early 1950s, engineers at the Massachusetts Institute of Technology (MIT) completed the Whirlwind I, designed to train pilots. Project Whirlwind introduced magnetic core memory to the world.

The first commercial computer was the 1951 Univac (Universal Automatic Computer) built by the makers of ENIAC for the US Census Bureau. It was huge, weighing 16,000 pounds (7,258 kilograms) and containing 5,000 vacuum tubes. He gained fame when he correctly predicted Dwight D’s success. Only votes counted when Eisenhower was president. The UNIVAC could perform 1,000 calculations per second, an amazing feat at the time.

In 1956, IBM’s 305 Random Access Memory (RAMAC) was the first memory with a hard disk. Piece by piece, the modern electronic computer began to come together.

In 1968, Douglas Engelbart demonstrated the prototype of the modern computer, which included a mouse and a graphical user interface (windows, icons, and menus). This shows that the benefits of computers can go beyond academics and technologists to the general public.

Bill Hewlett and Dave Packard, two friends who met on a camping trip, started working in a garage in Palo Alto, California. Their first product was an oscillator for testing audio equipment. Hewlett-Packard’s HP 9100A scientific calculator was released in 1968 and its advertising used the phrase “personal computer”. Their (real) first computer was the HP-85, released in 1980.
