American Journal of Computer Science and Information Technology (AJCSIT) is an intercontinental free access, peer reviewed journal. IBM’s brand recognition, along with a massive marketing campaign, ignites the fast growth of the personal computer market with the announcement of its own personal computer (PC). The first IBM PC, formally known as the IBM Model 5150, was based on a 4.77 MHz Intel 8088 microprocessor and used Microsoft´s MS-DOS operating system. The IBM PC revolutionized business computing by becoming the first PC to gain widespread adoption by industry. The IBM PC was widely copied (cloned”) and led to the creation of a vast ecosystem” of software, peripherals, and other commodities for use with the platform.
The US Army asked Bell Laboratories to design a machine to assist in testing its M-9 gun director, a type of analog computer that aims large guns to their targets. Mathematician George Stibitz recommends using a relay-based calculator for the project. The result was the Relay Interpolator, later called the Bell Labs Model II. The Relay Interpolator used 440 relays, and since it was programmable by paper tape, was used for other applications following the war.
The DN100 is based on the Motorola 68000 microprocessor, high-resolution display and built-in networking – the three basic features of all workstations. Apollo and its main competitor, Sun Microsystems, optimized their machines to run the computer-intensive graphics programs common in engineering and scientific applications. Apollo was a leading innovator in the workstation field for more than a decade, and was acquired by Hewlett-Packard in 1989.
The Computer Technology Endorsement program is the first 16 credit hours of the full master’s degree in classroom technology. Teachers adding this certificate to their existing Ohio teacher license will be prepared to provide leadership in technology for local, state or national education initiatives, but will also earn the credential for high quality and be licensed to teach computer science courses in K-12 public schools.
Wang was a successful calculator manufacturer, then a successful word processor company. The 1973 Wang 2200 makes it a successful computer company, too. Wang sold the 2200 primarily through Value Added Resellers, who added special software to solve specific customer problems. The 2200 used a built-in CRT, cassette tape for storage, and ran the programming language BASIC. The PC era ended Wang’s success, and it filed for bankruptcy in 1992.
