The 1980s saw the minicomputer age plateau as PCs were introduced. Manufacturers such as IBM, DEC and Hewlett-Packard continued to manufacture 14-inch hard drive systems as industry demanded higher storage; one such drive is the 1980 2.52 GB IBM 3380. But it was clear that smaller Winchester storage systems were eclipsing large platter hard drives.
The A-0 high-level compiler is invented by Grace Murray Hopper. April 1952: US IBM introduces the IBM 701, the first computer in its 700 and 7000 series of large scale machines with varied scientific and commercial architectures, but common electronics and peripherals. Some computers in this series remained in service until the 1980s.
In 1984, the U.S. Census Bureau began collecting data on computer and Internet use in the United States; their first survey showed that 8.2% of all U.S. households owned a personal computer in 1984, and that households with children under the age of 18 were nearly twice as likely to own one at 15.3% (middle and upper middle class households ...
For example, the 1961 Semiconductor Network Computer (Molecular Electronic Computer, Mol-E-Com), [10] [11] [12] the first monolithic integrated circuit [13] [14] [15] general purpose computer (built for demonstration purposes, programmed to simulate a desk calculator) was built by Texas Instruments for the US Air Force.
The first digital electronic computer was developed in the period April 1936 - June 1939, in the IBM Patent Department, Endicott, New York by Arthur Halsey Dickinson. [35] [36] [37] In this computer IBM introduced, a calculating device with a keyboard, processor and electronic output (display). The competitor to IBM was the digital electronic ...
1985: Case formally launches Quantum Computer Services from the "ashes" of Control Video, starting the company that would become AOL. 1989 : Quantum Computer Services is renamed America Online.
The machine was not intended to be a practical computer but was instead designed as a testbed for the Williams tube, the first random-access digital storage device. [113] Invented by Freddie Williams and Tom Kilburn [114] [115] at the University of Manchester in 1946 and 1947, it was a cathode-ray tube that used an effect called secondary ...
