[2] [3] In 1980, Intertec introduced the CompuStar, a multiuser microcomputer housed in a more standard desktop form factor. [4] Both computers sold steadily well in the first two years, with the company earning $3.7 million on $17.2 million in sales by 1981. That year, the company filed its initial public offering.
The Intertec SuperBrain was an all-in-one commercial microcomputer that was first sold by Intertec Data Systems Corporation of Columbia, South Carolina, USA in 1979.The machine ran the operating system CP/M and was somewhat unusual in that it used dual Z80 CPUs, the second being used as a disk controller.
PDP-1 PDP-6 PDP-7 PDP-8/e PDP-11/40 PDP-12 PDP-15 (partial) PDP-15 graphics terminal with light pen and digitizing tablet. Programmed Data Processor (PDP), referred to by some customers, media and authors as "Programmable Data Processor," [1] [2] [3] is a term used by the Digital Equipment Corporation from 1957 to 1990 for several lines of minicomputers.
The instruction set of the upper 3000 series is composed mostly of 24-bit instructions (packed two per word), but also contained some 48-bit instructions. The lower 3000 is based on a 24-bit subset of those available on the upper 3000 systems. It is therefore possible to write programs which will run on all 3000 systems.
The Burroughs Large Systems Group produced a family of large 48-bit mainframes using stack machine instruction sets with dense syllables. [NB 1] The first machine in the family was the B5000 in 1961, which was optimized for compiling ALGOL 60 programs extremely well, using single-pass compilers.
Because computer parts contain hazardous materials, there is a growing movement to recycle old and outdated parts. [67] Computer hardware contain dangerous chemicals such as lead, mercury, nickel, and cadmium. According to the EPA these e-wastes have a harmful effect on the environment unless they are disposed of properly.
Also simply application or app. Computer software designed to perform a group of coordinated functions, tasks, or activities for the benefit of the user. Common examples of applications include word processors, spreadsheets, accounting applications, web browsers, media players, aeronautical flight simulators, console games, and photo editors. This contrasts with system software, which is ...
Cable modem termination system. A cable modem termination system (CMTS, also called a CMTS Edge Router) [1] is a piece of equipment, typically located in a cable company's headend or hubsite, which is used to provide data services, such as cable Internet or Voice over IP, to cable subscribers.
