WHAT’S A WORKSTATION (third)

Tuesday, January 15th, 2008

A workstation welded wire mesh also differs from shared minicomputers or mainframes in graphics capablity. Workstations cram all types of pictures, symbols, and text from more than one application into individual “windows” on an oversized, high-resolution screen. But the price/performance ratio welded wire mesh may be one of the biggest differences between workstations and shared processing systems. Workstations first became practical with the emergence of powerful 32-bit microprecessors in the early 1980s. Because workstations are actually relatively small modular computing elements, they use common low-cost microprocessors and other circuitry. Mainframe and minicomputers, which operate much faster to serve all their users at once, must use exotic and far more expensive semiconductor technology and cooling welded wire mesh schemes.

On the low end, the distinction between personal computers and wordstations has begun to fade as Apple, IBM, Compaq, and others have introduced models that rival low-end workstations in power and graphics capability. The boundary will continue to erode to the point where, someday, most desktop computers will have enough power-including graphics and networking capabilities-to be called workstations. When that day comes, only the simplest of desktop computers will be called “personal computers”.

Workstations perforated metal differ from conventional computer systems in providing each user with a guaranteed amount of processing power at all times. Conventional time-share perforated metal computing systems can slow each user’s processing to a crawl if many users compete for resources at once.

Workstations reveal thir true power when linked into networks through two kinds of machines called “servers”. One such machine, the file server, stores and retrieves data files for the workstations: it acts as the central data-storage depot for the network.

A workstaion perforated metal user who needs additiona computing resources to run a specialized or time-consuming task can direct it to the computer server, which mayh come frome the workstation manfacture or another company. The computer server rus the task when it has the time, Meanwhile, the user can do other tasks on the workstation.

A workstation expanded metal is a powerful, 32-bit computer tahat fits on a desk, butr differs from personal computers in its greater power and sharper graphics. At the moment,expanded metal workstations fall somewhere between personal computers and the larger iminicomputer or mainframe systems, althrough the distinction between these systems is becoming increasingly blurry.

Many low-end workstations provide more power than a Digital Equipment VAX11/780 minicomputer, expanded metal which until a few years ago was an engineering and scientific standard. Also, each workstation is devoted to one person at a time, whereas the old VAX parceled its resources among20. This extra computing and graphics power lets workstations handle comples tasks that are impractical on a personal computer or that would be one of many demands on mainframe or minicomputer system.
