Mainframe: Central Processing Unit, main memory, and control units of a computer typically housed in one large cabinet or in a number of smaller ones grouped together. The term only applies to large computers.
[edit] Mainframes and large minicomputers
Time shared computer terminals connected to central computers, such as the TeleVideo ASCII character mode smart terminal pictured here, were sometimes used before the advent of the PC.
platform Another term for computer hardware, including microcomputers, workstations, and mainframe computers, or for underlying software, like an operating system, that provides services to layered software.
mainframe: A term originally referring to the cabinet containing the central processor unit or "main frame" of a room-filling Stone Age batch machine.
The transition from mainframes with batch processing to workstations and desk-top personal computers enabled the use of tools, as in spatial analysis.
These products (some of which are still in production) can provide a very complete picture of a mainframe computing environment, supporting exactly the kinds of impact analysis required for ITIL-based processes such as Incident and Change Management.
It can be run on mainframes, UNIX platform PCs and workstations as well as DOS-based PC's. The first version for UNIX was released in 1981, and the first PC version was released in 1986.
VM stands for virtual machine, the name and concept behind one of IBM's two principal mainframe operating systems.
Information and images that are important to your process or government should be stored on a server (or a mainframe acting as a server) and backed up either on a different computer or on different media.
My 30-plus years of tinkering with GIS has seen its environments evolve from mainframe computers to mini-computers, to personal computers, to distributed computing, to web services and now the offshoot of Service-Oriented Architecture.
range from Macintosh and PC to workstations to mainframes
programs which work on micro-computers are generally very limited in their ability to handle large databases
most major GIS programs now operate on several different platforms ...
In the past 25 years, GIS software development and applications have migrated from mainframe computers to minicompu ters to personal computers (PCs) to networked UNIX workstations.
The Architecture Evolution Plan replaced outdated mainframe computers with a modern, distributed IT architecture.
Some of the DOD mainframe/control systems may have the Y2K problem, however the major systems should be clear by the time the problem comes around.
It was developed as a mainframe based system in support of federal and provincial resource planning and management. Its strength was continent-wide analysis of complex data sets. The CGIS was never available in a commercial form.
The size of a word varies from one computer to another, depending on the CPU. For computers with a 16-bit CPU, a word is 16 bits (i.e. 2 bytes). On large mainframes, a word can be as large as 64 bits (i.e. 8 bytes).
The summaries listed total sales, percentages of magazines returned from grocery store racks, and so on. These kinds of operations consumed the majority of all mainframe resources through the 1980's, ...
