The history of a computer 1946 until today(2017)

The first computer (ENIAC) was invented by J. Presper Eckert and John Mauchly at the University of Pennsylvania and began construction in 1943 and was not completed until 1946. It occupied about 1,800 square feet and used about 18,000 vacuum tubes, weighing almost 50 tons.

3 Years Later a new computer called CSIRAC was borned Sydney,Australia by the Council of Scientific and Industrial Research or use in its Radio physics Laboratory in Sydney, CSIRAC was designed by British-born Trevor Pearcey, and used unusual 12-hole paper tape. It was transferred to the Department of Physics at the University of Melbourne in 1955 and remained in service until 1964

1 year later the 1101, designed by ERA but built by Remington-Rand, was intended for high-speed computing and stored 1 million bits on its magnetic drum, one of the earliest magnetic storage devices and a technology which ERA had done much to perfect in its own laboratories.
The first practical stored-program computer to provide a regular computing service, EDSAC is built at Cambridge University using vacuum tubes and mercury delay lines for memory.One major advance in programming was Wilkes' use of a library of short programs, called “subroutines,” stored on punched paper tapes and used for performing common repetitive calculations within a lager program.
Based on ideas from Alan Turing, Britain´s Pilot ACE computer is constructed at the National Physical Laboratory.The design packed 800 vacuum tubes into a relatively compact 12 square feet.
Built by a team led by engineers Frederick Williams and Tom Kilburn, the Mark I serves as the prototype for Ferranti’s first computer – the Ferranti Mark 1. The Manchester Mark I used more than 1,300 vacuum tubes and occupied an area the size of a medium room.
5 years later people start putting keyboard into computer.The keyboard start become the input of computers.
The typical PDP-1 computer system, which sells for about $120,000, includes a cathode ray tube graphic display, paper tape input/output, needs no air conditioning and requires only one operator; all of which become standards for minicomputers. Its large scope intrigued early hackers at MIT, who wrote the first computerized video game, SpaceWar!, as well as programs to play music.
The 2116A is HP’s first computer. It was developed as a versatile instrument controller for HP's growing family of programmable test and measurement products. It interfaced with a wide number of standard laboratory instruments, allowing customers to computerize their instrument systems. The 2116A also marked HP's first use of integrated circuits in a commercial product.

In many years people have created a lot of computers,the no screen one,fancy one,long screen one,....And until today we ended up with this computer.

Computers have change a lot in time maybe in the future we can have a automatic computer,.....
