Pascal introduced
The Pascal programming language, named after Blaise Pascal, a French physicist, mathematician and inventor turned philosopher, is introduced by Professor Niklaus Wirth. His aim with Pascal was to develop a programming language applicable to both commercial and scientific applications, and which could also be used to teach programming techniques to college students. It was closely based on ALGOL 60, which Wirth had also helped to develop. -
Intel introduces first microprocessor
The first microprocessor, the Intel 4004 appears. Developed for a calculator maker, it could perform up to 90,000 operations per second. Federico Faggin led design and Ted Hoff led architecture. -
IBM SCAMP is developed
Under engineer Dr. Paul Friedl, the Special Computer APL Machine Portable (SCAMP) personal computer prototype developed. IBM’s first personal computer, designed to run APL programming language in compact enclosure. He used SCAMP prototype to gain approval within IBM to promote and develop IBM’s 5100 family of computers, including the most successful, the 5150, also known as the IBM Personal Computer (PC), introduced in 1981. From concept to finish, SCAMP took only six months to develop. -
Ethernet and Local Networks
Computers have to communicate down the hall, as well as globally. Local area networks (LANs) evolved from early links to peripheral devices. 1973 marks the birth of the standard that will eventually prevail: Ethernet. Created as part of Xerox vision of an “office of the future” comprised of connected PCs, Ethernet adapts techniques from wireless ALOHAnet to treat cables as passive medium, like air (“ether”) between radio stations. -
