2019年10月21日 · The history of computer dated back to the period of scientific revolution (i.e. 1543 – 1678). The calculating machine invented by Blaise Pascal in 1642 and
ancient abacus and a modern computer seems vast, but the principle—making repeated calculations more quickly than the human brain—is exactly the same. Read on to learn more about the history of computers—or take a look at our article on how computers work.

In order to understand today's computers, it is important to study how computers evolved through time by discussing some of the major achievements. This section deals with the history of computers and identifies the major technological achievements of the four computer generations.
This paper is intended to provide an introduction to the study of the history of computing for someone who has a good knowledge of computer science, but only a limited knowledge of the history of computing and no formal training in any kind of historical study. It has three parts.
Typical 1968 prices—EX-cluding maintenance & support! 1948 and beyond... Â 1900 operations per second in a smaller and more efficient package than ENIAC. Â Invention of the microprocessor, by Ted Hoff and Federico Faggin at Intel. Â Steve Wozniak, co-founder of Apple Computer, is credited with developing the first mass-market home computers.
Computers were invented to ‘‘compute’’: to solve ‘‘complex mathema-tical problems,’’ as the dictionary still defines that word.1 They still do that, but that is not why we are living in an ‘‘Information Age.’’ That reflects other things that computers do: store and retrieve data, manage
• Examples of new digital computers were Atanasoff-Berry Computer, the Z3, the Colossus and ENIAC (which was 1000 times faster than its contemporaries). • These computers were hand built and relied on vacuum tube technology. For input assimilation they relied on punched cards or punched paper tape.
First real “computer scientist”. Created first Compiler because she was tired of writing “machine code” by hand. Greatly improved programming speed and efficiency. “The most important invention of the 20th century...” Invented by Jack Kilby at Texas Instruments in 1957. Enabled many transistors to be grouped into a single package.
No history of modem computers would be complete without a discussion of the contributions of Charles Babbage (1791-1871). In a preelectronic era, he worked out many of the concepts of automatic computation that we find in today's digital computers. His success was limited by the state of engineering and his temper-
