Category: What was first computer invented ?

In 1948, the SSEM (Small-Scale Experimental Machine), also known as the Manchester Baby or Baby, was introduced. Frederic Williams designed it, and with the assistance of Geoff Tootill, Tom Kilburn (his protégée) built it at the University of Manchester in England. The first electronically-stored program that was able to electronically store and execute a program written by Kilburn, which can calculate the highest proper factor of an integer with the help of repeated subtraction instead of division. On 21 June 1948, Kilburn’s program was executed.

In England, at the University of Cambridge Mathematical Laboratory, the EDSAC was designed and built by Maurice Wilkes, which was the second stored-program computer. It performed its first calculation on 6 May 1949. It was designed with an implementation of tic-tac-toe screened on a 6-inch cathode ray tube.

Another computer, Manchester Mark 1, was able to run stored programs. Also, at the Victoria University of Manchester, the first version of the Mark 1 computer was built in April 1949 that was able to run the program. Later, it was used to run a program for nine hours without error to search for Mersenne primes on 16 and 17 June.

In 1937, the ABC (Atanasoff-Berry Computer) was started to develop by John Vincent Atanasoff and graduate student Cliff Berry, which stands for. Although the ABC computer was continuing in the development phase at the Iowa State College in 1937, later continued at Iowa State University until 1942.

More than 300 vacuum tubes were used by the Atanasoff-Berry Computer for digital computation. It had no CPU as it was not able to programming. On 19 October 1973, it was declared by US Federal Judge Earl R. Larson that the ENIAC patent by John Mauchly and J. Presper Eckert was invalid.

In 1943, at the University of Pennsylvania, John Mauchly and J. Presper Eckert started to invent the ENIAC, and it was continuing in the development phase but not completed until 1946. It used about 18,000 vacuum tubes and occupied about 1,800 square feet, weighing almost 50 tons. The first digital computer, the ENIAC is still considered by many people as it was fully functional. But, according to the judge ruled, the first digital computer was ABC computer.

In mid-1936 and 1938, German Konrad Zuse created the Z1 in his parents’ living room. It was the first really functional modern computer and also considered the first electromechanical binary programmable computer.

The concept of first modern computer

In 1936, Alan Turing first proposed the Turing machine and became the basis for computing and computers. The Turing machine was able to print symbols in a manner that simulates a person following a sequence of logical instructions.

The first electric programmable computer

Tommy Flowers developed the first electric programmable computer that was known as Colossus, and in 1943, it was demonstrated for the first time. It was developed to help for reading encrypted German messages of the British code breakers.

In 1822, the first automatic computing machine was designed and developed by Charles Babbage, which was the Difference Engine. It had the ability to calculate numerous sets of numbers and generating hard copies of the results. Ada Lovelace helped the Babbage to developed the Difference Engine. The first computer by Babbage is considered the programmer, and he also wrote notes and sketches about the Difference Engine. Inappropriately, Babbage was unable to complete a full-portion functional type of this machine, as he had no sufficient fund. Later the Difference Engine No 2 was completed by the London Science Museum in June 1991. Later the printing mechanism was also completed by the London Science Museum.

In 1837, the Analytical Engine that was the first general mechanical computer, was proposed by Charles Babbage. It was the first general-purpose computer concept, which contained basic flow control, Arithmetic Logic Unit (ALU), integrated memory, etc. Unfortunately, due to less funding, Charles Babbage also was unable to build this computer while he was alive. Henry Babbage (Charles Babbage’s youngest son) completed this computer and performed basic calculations too.

There are several classifications of the computer that create confusion; there is no easy to find the answer to the first computer invention. In 1822, Charles Babbage created the first mechanical computer, which was not really considered to resemble the used computer today. Therefore, the description is below that explains the invention of the first computer.

When was first used the “computer” word?

In 1613, the word computer was used for the first time by Richard Braithwaite in the book named The Yong Mans Gleanings. Until the 19th century, the definition of a computer was the same, when the industrial revolution created the machines. These machines had the main purpose of calculating.
