charles babbage
born 12/26/1791 Charles designed the Analytical Engine, the first automatic calculator. The engine was never developed , but the drawings and descriptions are similare to todays computers. Mr.Babbage was awarded the Gold Medal of the Royal Astronomical Society. -
herman hollerith
born 2/29/1860 herman hollerith created hollerith tabulating machine, it automatically read data from punch cards. 1896 hollerith started the tabulating machine company, later becoming international business machines (IBM). herman studied at City College of New York during the year 1875 and
Columbia University School of Mines,1879 -
Z1 Computers
1936 Konrad Zuse created the Z-1 Computer. it was a mechanical calculator which included control unit and seperate memory functions.This computer was destroyed in the bombardment of Berlin in December 1943, during World War II. -
univac
the first commereically successful digital computer, operated on magnetic tape instead of punch cards. the last to use vacuum tubes to store data, UNIVAC 1107 continue today as products of the Unisys company.also considered first generation computer. -
1st generation computers
The first computers used vacuum tubes for circuitry and magnetic drums for memory, and were often enormous, taking up entire rooms. They were very expensive to operate and in addition to using a great deal of electricity, generated a lot of heat, which was often the cause of malfunctions -
2nd generation computer
Transistors replaced vacuum tubes and ushered in the second generation of computers. The transistor was far superior to the vacuum tube, allowing computers to become smaller, faster, cheaper, more energy-efficient and more reliable than their first-generation predecessor -
eniac
electronic numerical integrator and computer was the first successful high-speed electronic digital computer. using 18,000 vacuum tubes filling 1,800 sq ft.When ENIAC was announced in 1946 it was heralded in the press as a "Giant Brain" -
3rd generation computers
the integrated circuit was the hallmark of the third generation of computers. Instead of punched cards, the 3rd generation computers used keyboards and monitors and interfaced with an operating system, which allowed the device to run many different applications at one time with a central program that monitored the memory. -
jack kilby
jack kilby created inegrated circuits which were small chips containing thousands transistors. it enabled computers to become smaller and lighter.He is also the inventor of the handheld calculator and the thermal printer, for which he has patents. -
basic
easily learned by begginning programmers, became key language for PC, and led to creation of microsoftBASIC remains popular in many dialects and in new languages influenced by BASIC, such as Microsoft's Visual Basic. -
4th generation computer
The microprocessor brought the fourth generation of computers, as thousands of integrated circuits were built onto a single silicon chip.The first generation filled an entire room could now fit in the palm of the hand. The Intel 4004 chip, developed in 1971, located all the components of the computer-from the central processing unit and memory to input/output controls-on a single chip. -
introduction of the GUI
introduction into what you see is what you get (wysiwyg). it was easier interaction with computers. apple was the first to take advantage of the product. also it was not invented by a computer company. -
altair computer
sold as a kit for $395.00. it had no keyboard or monitor also not user-friendly. -
steve jobs
help create apple I & II. operating system stored in ROM.he became a member of the board of directors of The Walt Disney Company in 2006, when Disney acquired Pixar. -
Apple II
4 kb of ram. featured color, sound, and games paddles.the Apple II was among the first successful personal computers; it launched the Apple company into a successful business -
visical
VisiCalc was the first spreadsheet computer program, originally released for the Apple II. It is often considered the application that turned the microcomputer from a hobby for computer enthusiasts into a serious business tool, and is considered the Apple II's killer app. -
wordstar
WordStar is a word processor application that had a dominant market WordStar was deliberately written to make as few assumptions about the underlying system as possible, allowing it to be easily ported across the many platforms that proliferated in the early 1980s. -
bill gates
born 10/2/1955 bill gates former chief executive and chairman of Microsoft, operating system for IBM PSs. PSs using intel chip used MS-DOC. microsofts neign had begun.wrote interpreter program and sold it to Altair. -
osborne computer
first portable computer, preinstalled with spreadsheet and word processing software. cost 1,795. overnight success -
pagemaker
PageMaker was one of the first desktop publishing programs, introduced in 1985 by Aldus, initially for the then-new Apple Macintosh and in 1987 for PCs running Windows -
