To discuss the invention of computers we must first discuss what the definition of a computer is. ... The beginning of computers has their roots in mathematics with the invention of the abacus. ... In fact all of the first “computers” were for ease in doing complex mathematics problems. ... The first digital computers were developed in the late 1930’s, but these were monstrous machines that used up enormous amounts of energy and floor space. World War II brought in the demand for the refinement of computers. They became able to do more complex problems and developments in memory brought on the replacement of more human tasks done in the workplace to be done by computers. All of these computers were powerful but mostly single purposed and extremely expensive. The development of computers was somewhat halted until developments in solid state physics brought on the possibility of RAM (random access memory) during the next decade. ...
Keeping with the invention of computers rooted in mathematics, we must discuss one of the first people to think of modern computing Charles Babbage. Charles Babbage was a mathematics professor in Cambridge, England. ... These primitive “computers” were extremely slow, although they do represent a huge step forward in computing by providing a means of memory and input/output. ...
The beginning of World War II brought on the need for computers to do more, especially for the military. ... He was captivated by the success of the ENIAC, and in 1945 he conducted an abstract study of computers and came up with a report called the “first draft of a report on the EDVAC”. ... From it he defines a concept for the structure of computers called the “von Neumann Architecture”. ...
The UNIVAC had one thing in particular about the design that set it apart from all of the digital computers that came before it. ... The first companies to use these two computers were government agencies and scientific organizations. ...
A third company entered the picture in the early 1950’s that changed the way data was stored in computers. ...
During the Mid 1950’s there was a huge surge in the number of private companies selling cheap drum based computers.
