1961: Transistorized computers were designed that were capable of ongoing calculations of flight positioning.The purpose of SAGE was to detect incoming Soviet missiles. 1958: The SAGE system connected 23 separate computer sites throughout the United States and Canada.This computer was designed for general purposes. 1957: MIT researchers succeeded in building a programmable computer containing transistors.The release of this system was the beginning of IBM’s involvement in the computer market. 1954: IBM began selling its “Defense Calculator” to some corporate entities, such as aircraft companies and research laboratories.This computer weighed 29,000 pounds, and it contained 5,200 vacuum tubes. 1951: The UNIVAC 1 began attracting the attention of the public.This system held 1 million bits on an internal magnetic drum. 1950: Remington-Rand built the ERA 1101, one of the world’s first commercially produced computers.The researchers wrote and ran the first computer program on the Manchester Baby. 1948: Researchers with the University of Manchester developed the “Manchester Baby,” which was a machine designed to test memory technology.After his release, he moved forward with building the calculator. 1944: An Austrian engineer named Curt Herzstark spent his time at the Buchenwald concentration camp working on preliminary designs of a four-function calculator.This computer was capable of performing floating point binary math. 1941: Konrad Zuse, a German engineer, designed the Z3 computer.The garage was the location of research, development, and manufacturing for the first products produced by the new company. 1939: Bill Hewlett and Dave Packard founded Hewlett-Packard in a rented garage in Palo Alto, California.Stibitz called this circuit a “Model K” adder because he created it at home on a kitchen table. 1937: George Stibitz, a Bell Laboratories scientist, originated the use of relays as a demonstration adder.The computer could run BASIC programs once the interpreter had been loaded.ġ996: Sergey Brin and Larry Page develop the Google search engine at Stanford University.ġ978: Accountants rejoice at the introduction of VisiCalc, the first computerized spreadsheet program. Keying the loader required setting a bank of eight switches up or down and pressing the “load” button, once for each byte of the program, which was typically hundreds of bytes long. To program the machine after switching it on the bootstrap loader program had to be entered, without error, in binary, then a paper tape containing a BASIC interpreter loaded from a paper-tape reader. These machines both featured a front panel with switches and lights, which communicated with the operator in binary. The Altair and IMSAI were essentially scaled-down minicomputers and were incomplete: to connect a keyboard or teleprinter to them required heavy, expensive “peripherals”. This was followed by the IMSAI 8080 computer, with similar abilities and limitations.

The Altair 8800, introduced in a Popular Electronics magazine article in the January 1975 issue, at the time set a new low price point for a computer, bringing computer ownership to an admittedly select market in the 1970s. ĭevelopment of the single-chip microprocessor was an enormous catalyst to the popularization of cheap, easy to use, and truly personal computers. The basis of the fourth generation is the microprocessor, a computer processor contained on a single large-scale integration (LSI) MOS integrated circuit chip. Third generation minicomputers were essentially scaled-down versions of mainframe computers, whereas the fourth generation’s origins are fundamentally different.
