should the PC boot with depending on what application the user wants to run on
the PC at that time. Thus the PC can work both as a Windows machine as well as a
Linux machine. This feature provides great flexibility in the usage of a wide
variety of applications for different OSs on the same PC.
PCs generally cost from a few tens of thousands to about a lakh of rupees,
depending on their capabilities and capacity. The tremendous growth and
continuing potential of the PC market has brought many manufacturers to this
arena. A few of the major PC manufacturers are IBM, Apple, Compaq, Dell,
Zenith, Siemens, Toshiba, and Hewlett-Packard.
A workstation is a powerful desktop computer designed to meet the computing
needs of engineers, architects, and other professionals who need greater processing
power, larger storage, and better graphics display facility than what PCs provide.
For example, workstations are commonly used for computer-aided design (CAD), in which industrial designers create pictures of technical parts or assemblies. To
process and view these complex and detailed diagrams, a computer with great
processing power, large storage, and good graphics display monitor is needed.
Workstations are also used" for simulation of complex scientific and engineering
problems and for visualizing the results of simulation. They are also used for
multimedia applications, such as for creating special audio-visual effects for
television programmes and movies.
A workstation looks very much like a PC and is typically used by only one person
at a time, just like a PC. The following characteristics are often used to distinguish
between the two:
Processing power. The processing power of a workstation is several times
(typically 5 to 10 times) more than that of an average power of a PC.
2. Storage capacity. Workstations have larger main memory (typically 0.5 GB
to a few GB) as compared to PCs, which have few tens or hundreds of MB of
main memory. The hard disk capa...
