What is a Smart Terminal™?
• A computing model where applications are running on a server, while a desktop device is a simple display unit with keyboard and pointing device
• Also referred to as “server-based computing” or “client/server model”
• Similar to old day’s time-sharing except the desktop device is a full graphics unit

Client Types
• Thin client (i.e. terminals with no local hard disk)• Thick (fat) client (i.e. PCs or converted PCs)

![Page 8: Thin Client - New Technology Deflection Point Presented to: LITWG of Washington State Everett Public Library January 10, 2002 Presented by: Dr. Chong Lee](https://reader031.vdocument.in/reader031/viewer/2022020417/56649e3b5503460f94b2cff1/html5/thumbnails/8.jpg)
A Brief History
• Mid 90s: X Windows terminals for UNIX did not take off, as UNIX growth has slowed down
• 1996: Introduction of MS Windows-based terminals• Late 90s: Microsoft partnership with Citrix fueled the
growth of the Windows terminal market
![Page 9: Thin Client - New Technology Deflection Point Presented to: LITWG of Washington State Everett Public Library January 10, 2002 Presented by: Dr. Chong Lee](https://reader031.vdocument.in/reader031/viewer/2022020417/56649e3b5503460f94b2cff1/html5/thumbnails/9.jpg)
Smart Terminal Advantages
• Centralized computer resource management, resulting in lower support and ongoing maintenance cost
• High system and network security• High system availability (uptime)• Longer product life cycle• Energy saving• Space saving
![Page 10: Thin Client - New Technology Deflection Point Presented to: LITWG of Washington State Everett Public Library January 10, 2002 Presented by: Dr. Chong Lee](https://reader031.vdocument.in/reader031/viewer/2022020417/56649e3b5503460f94b2cff1/html5/thumbnails/10.jpg)
Smart Terminal Disadvantages
• Dependency on the server (single point failure)• High level technical expertise required
![Page 11: Thin Client - New Technology Deflection Point Presented to: LITWG of Washington State Everett Public Library January 10, 2002 Presented by: Dr. Chong Lee](https://reader031.vdocument.in/reader031/viewer/2022020417/56649e3b5503460f94b2cff1/html5/thumbnails/11.jpg)
Solutions for Disadvantages
• Back up servers and redundancy– i.e. “fail over”
• Commercial solution– i.e. Veicon, eliminating the need for in-house
development and maintenance
![Page 12: Thin Client - New Technology Deflection Point Presented to: LITWG of Washington State Everett Public Library January 10, 2002 Presented by: Dr. Chong Lee](https://reader031.vdocument.in/reader031/viewer/2022020417/56649e3b5503460f94b2cff1/html5/thumbnails/12.jpg)
Why did thin client technology not take off in libraries?• PC-based solution is quick and easy to grow• Uncertainty and lack of experience with the new
technology• Lack of budgetary information• Unavailable, qualified IT person• Lack of certain solutions with the early thin client
features, i.e. floppy disk option
![Page 13: Thin Client - New Technology Deflection Point Presented to: LITWG of Washington State Everett Public Library January 10, 2002 Presented by: Dr. Chong Lee](https://reader031.vdocument.in/reader031/viewer/2022020417/56649e3b5503460f94b2cff1/html5/thumbnails/13.jpg)
Smart Terminal vs. PC
• MTBF (Mean Time Between Failure) – thin client: 98,000 hours – PC: 20,000 hours
![Page 14: Thin Client - New Technology Deflection Point Presented to: LITWG of Washington State Everett Public Library January 10, 2002 Presented by: Dr. Chong Lee](https://reader031.vdocument.in/reader031/viewer/2022020417/56649e3b5503460f94b2cff1/html5/thumbnails/14.jpg)
System Price Comparison: Smart Terminal (ST) vs. PC• Capital vs. non-capital cost
– Ratio: 1:2
• Capital cost: ST with Server vs. PC– Ratio: 1:1
• Non-capital cost: ST vs. PC– Ratio: 1: 3
• Overall TCO (Total Cost of Ownership): ST vs. PC– 60% - 70% savings with TC solution

Capital Cost vs. Non-Capital Cost
• Capital cost: Equipment• Non-capital cost: installation, moves and changes,
staff training, security, applications, systems/network management, technical support, and on-going maintenance

Technology Deflection Points (over 50 years of computing history)
• Existing technology trend slows down, while a new technology trend accelerates– Mainframe to Mini– Mini to PC– PC to “thin client computing” driven by broadband Internet
(wired or wireless) and high speed servers
