Workstation - Super Fast Computer

In general term workstation means computer for specific reason connected with LAN. A workstation is a high-end microcomputer designed for technical or scientific applications. Intended primarily to be used by one person at a time, they are commonly connected to a local area network and run multi-user operating systems. The term workstation has also been used to refer to a mainframe computer terminal or a PC connected to a network. Typically workstations had offered higher performance than personal computers, especially with respect to CPU and graphics, memory capacity and multitasking cability.

Workstation are optimized for the visualization and manipulation of different types of complex data such as 3D mechanical design, engineering simulation (e.g. computational fluid dynamics), animation and rendering of images, and mathematical plots. Consoles consist of a high resolution display, a keyboard and a mouse at a minimum, but also offer multiple displays, graphics tablets, 3D mice (devices for manipulating and navigating 3D objects and scenes), etc. Workstations are the first segment of the computer market to present advanced accessories and collaboration tools.

History of Workstation
In early days workstations were generally dedicated minicomputers; a system designed to support a number of users would instead be reserved exclusively for one person. A notable example was the PDP-8 from Digital Equipment Corporation, regarded to be the first commercial minicomputer.

Perhaps the first computer that might qualify as a "workstation" was the IBM 1620, a small scientific computer designed to be used interactively by a single person sitting at the console. It was introduced in 1959. In 1965, IBM introduced the IBM 1130 scientific computer, which was meant as the successor to the 1620. Both of these systems came with the ability to run programs written in Fortran and other languages. Both the 1620 and the 1130 were built into roughly desk-sized cabinets. Both were available with add-on disk drives, printers, and both paper-tape and punched-card I/O. A console typewriter for direct interaction was standard on each.

The Lisp machines developed at MIT in the early 1970s pioneered some of the principles of the workstation computer, as they were high-performance, single-user systems intended for heavily interactive use. The first computer designed for single-users, with high-resolution graphics facilities (and so a workstation in the modern sense of the term) was the Xerox Alto developed at Xerox PARC in 1973. Other early workstations include the Three Rivers PERQ (1979) and the later Xerox Star (1981).

In the early 1980s, with the advent of 32-bit microprocessors such as the Motorola 68000, a number of new participants in this field appeared, including Apollo Computer and Sun Microsystems, who created Unix-based workstations based on this processor. Meanwhile DARPA's VLSI Project created several spinoff graphics products as well, notably the SGI 3130, and Silicon Graphics' range of machines that followed. It was not uncommon to differentiate the target market for the products, with Sun and Apollo considered to be network workstations, while the SGI machines were graphics workstations. As RISC microprocessors became available in the mid-1980s, these were adopted by many workstation vendors.

PC- Home Computer Trends, Types and Technology

Features of Workstations
*ECC memory
Workstations support the ECC memory.

* Memory Sockets
a larger number of memory sockets which use registered (buffered) modules

* Multiple processors
Workstations uses the multiple processors in their CPU.

* Multiple displays
It is also common part in the workstations.

*Professional Operating System
Workstations generally run a "business" or "professional" operating system version

* Expensive
Workstations tended to be very expensive, typically several times the cost of a standard PC and sometimes costing as much as a new car. However, minicomputers sometimes cost as much as a house.

* Costly components
The high expense usually came from using costlier components that ran faster than those found at the local computer store, as well as the inclusion of features not found in PCs of the time, such as high-speed networking and sophisticated graphics. Workstation manufacturers also tend to take a "balanced" approach to system design, making certain to avoid bottlenecks so that data can flow unimpeded between the many different subsystems within a computer.

*Higher Profit Margins
Workstations given their more specialized nature, tend to have higher profit margins than commodity-driven PCs.

*System
The systems that come out of workstation companies often feature SCSI or Fibre Channel disk storage systems, high-end 3D accelerators, single or multiple 64-bit processors, large amounts of RAM, and well-designed cooling.

* Good after sale service
The companies that make the products tend to have very good repair/replacement plans.

Workstation - SuperFast PC of new world

Low Cost Workstations
Now these days the line between workstation and PC is increasingly becoming blurred as the demand for fast computers, networking and graphics have become common in the consumer world, allowing workstation manufacturers to use "off the shelf" PC components and graphics solutions as opposed to proprietary in-house developed technology. Some "low-cost" workstations are still expensive by PC standards, but offer binary compatibility with higher-end workstations and servers made by the same vendor. This allows software development to take place on low-cost (relative to the server) desktop machines.

There have been several attempts to produce a workstation-like machine specifically for the lowest possible price point as opposed to performance. One approach is to remove local storage and reduce the machine to the processor, keyboard, mouse and screen. In some cases, these diskless nodes would still run a traditional OS and perform computations locally, with storage on a remote server. These approaches are intended not just to reduce the initial system purchase cost, but lower the total cost of ownership by reducing the amount of administration required per user.

This approach was actually first attempted as a replacement for PCs in office productivity applications, with the 3Station by 3Com as an early example; in the 1990s, X terminals filled a similar role for technical computing. Sun has also introduced "thin clients", most notably its Sun Ray product line. However, traditional workstations and PCs continue to drop in price, which tends to undercut the market for products of this type.
