Tips on setting up your workstation

Article Abstract:

Strategies are developed for the physical layout of computer workstations and the workspaces they occupy to ensure the optimal health and productivity of the users. The specific goals are to minimize eye and muscle fatigue and reduce the potential impacts of extremely low-frequency (ELF) electromagnetic emissions from workstation monitors. There is a lot of controversy as to whether ELF fields generated by monitor vertical deflection systems adversely affect the health of nearby users. Some countries, though, have already implemented standards of magnetic field flux densities below 1.0 microtesla 30 cm from the display screen, with other work in Scandinavia suggesting that ELF levels should be below 0.2 microtesla. Workspaces should be set up so no person in an adjoining cubicle is closer than 122 cm to the back of any other worker's monitor. Strategies to reduce eye and muscle fatigue include a large enough monitor to make data easy to read, placement of the monitor 10-to-20 degrees below the line of sight, placement of lights to eliminate glare on monitor, sufficient leg room and a chair with good back support.

ICs: the brains of a workstation

Article Abstract:

Advances in integrated circuit (IC) technology are resulting in powerful new microprocessors, graphics, memory and input/output management chips that enable the development of more powerful and cheaper workstations. Intel and Motorola complex-instruction-set computer processor architectures continue to dominate the microcomputer market, but reduced-instruction-set computer (RISC) processors pervade the workstation market. Future workstations will be based on new generations of current RISC processors, while existing implementations will enter the microcomputer market. New techniques are being employed to increase processor speed, including superpipelining, superscalar architectures and long-instruction-word processing. The rapidly increasing performance of RISC processors is not being complemented by improvements in dynamic random-access memory (RAM) chips, so cache memories employing fast static RAMs are being incorporated in workstation designs. The trend to higher chip integration and the most important user criteria for selection of a workstation are discussed.

It looks like a pc--or is it a workstation?

Article Abstract:

The differences between microcomputers and workstations are blurring, as microcomputers gain more of the performance, memory, functional capabilities and applications typical of workstations. There are some features that still tend to differentiate workstations from microcomputers, including television-like displays with resolutions of 1,000 or more lines, very sophisticated graphics manipulation and the ability to handle distributed computing applications. Workstation attributes that have migrated to the microcomputer domain include multitasking operating systems, windowing systems and a broad availability of engineering and scientific applications.
