This list of computer size categories attempts to list commonly used categories of computer by the physical size of the device and its chassis or case, in descending order of size. One generation's "supercomputer" is the next generation's "mainframe", and a "PDA" does not have the same set of functions as a "laptop", but the list still has ...
First, they were architecturally more diverse than prior mainframes and minicomputers in hardware and less diverse in software. Second, advances in VLSI made them less expensive (mini-price). These machines were market targeted to be cost-effective and quickly manufactured.
The term supercomputer itself is rather fluid, and the speed of today's supercomputers tends to become typical of tomorrow's ordinary computer. Supercomputer processing speeds are measured in floating-point operations per second, or FLOPS. An example of a floating-point operation is the calculation of mathematical equations in real numbers.
The Honeywell 6000 series computers were rebadged versions of General Electric's 600-series mainframes manufactured by Honeywell International, Inc. from 1970 to 1989. . Honeywell acquired the line when it purchased GE's computer division in 1970 and continued to develop them under a variety of names for m
The VAX 8600 was a successful model and at the time was the best selling high-end VAX. It was succeeded by the VAX 8800 family in 1987. The VAX 8600 has a CPU with an 80 ns cycle time (12.5 MHz) implemented with emitter coupled logic (ECL) macrocell arrays (MCAs).
The IBM System/360 (S/360) is a family of mainframe computer systems announced by IBM on April 7, 1964, [1] and delivered between 1965 and 1978. [2] System/360 was the first family of computers designed to cover both commercial and scientific applications and a complete range of applications from small to large.
The computer also includes memory and input/output (I/O) circuitry together mounted on a printed circuit board (PCB). Microcomputers became popular in the 1970s and 1980s and predecessors to these computers were mainframes and minicomputers.
The VAX ISA is considered a complex instruction set computer (CISC) design. DEC quickly dropped the −11 branding as PDP-11 compatibility was no longer a major concern. The line expanded to both high-end mainframes like the VAX 9000 as well as to the workstation-scale systems like the VAXstation series.
