  1. Thin Client Presented by.. Hetul Patel Network Engineer (American Computer Technology)

  2. What Is A Network? BranchOffices WindowsTerminalsand NCs RemoteComputing WinFrame & MetaFrameServer Farms Cross-PlatformDesktops Wireless Terminals and Information Appliances WebComputing • A group of computers working together. • Peer to Peer Network, Client/Server, Internet, etc. • Most common Technology in Networking:- Client/Server .

  3. What are Different Types Of Clients. • Client:-is a computing device/software that retrieves information from a server. • Thick Client:-is a computing device that includes a software operating system, a powerful processor and a wide range of applications that can execute on the computing device. • Thin Client:-is a low-cost computing device that works in an application server environment. It does not require state-of-the art, powerful processors and large amounts of RAM and ROM.

  4. What Is A Thin Client? NO… • An emaciated Library Patron. • A Program To Purge Expired Patron. • An Anorexic Library Budget. So Then What Exactly Is A Thin Client? • A Hardware/Software that runs application on a server, not on desktop. • Key strokes and mouse click are sent over network to the server to process and give back the result…… (screen). • Clients can be a low powered PC or a Thin client device. • They Don’t Have HDD, FDD, CDROMS, Cooling Fans, Very Low Processing Power.

  5. Power Full Server with dual processor,1gb Ram,10 MBps Network. (Compaq Proliants, HP Netserver & IBM NetFinity ) Thin Clients (IBM,Neoware,WYSE, SUN , Compaq,NCD etc..) OR A Low Processing PC. Citrix Meta Frame software Windows 2000/2003 Terminal Services. OR Windows CE,XP,NT. What Makes A Thin Client Network? Ideal For 30-40 Clients running common OPAC`s,Internet,Office software,etc HARDWARE SOFTWARE

  6. How Does A Thin Client Work? • About 1/3 Size Of PC. • Works In A Same Way And At Same Speed As Desktop PC. • Supports GUI And Windows Environment. • Can Be Configured On As Low As 16Mb Of RAM. • Same Feel As Working On Any Windows Based OS. • Remote Computation….Server Takes Care Of All The Processing. • Works On either Citrix`s ICA Or Microsoft's RDP Protocols (Both Require Only 20Kbps Speed Over Network To Work). • User Logs On TO The Server Via Web Portal And A Familiar Windows Base Environment is Replicated On TO Users Screens With Access To Application, Internet, Mail, Drives, Printers, Etc.

  7. Who are the Main Players ? • Microsoft – NT/2000/2003 Terminal Services (RDP)Remote Desktop Protocol • Citrix – MetaFrame(ICA)Intelligent Console Architecture ICA RDP

  8. Advantages Over Desktop Pc`s • Dramatically Decreases The TCO by 54% to 57%. • Decreases IT Cost By 80% Through Reduced Staff And Centralized Software Management. (Does not Crash, NO Help DESK) • Greatly Simplifies The Software Upgrade Over The Network. • Eliminates The Hardware Upgrades On Client Side. • Increases End User Productivity. (Limited Access To Authorized Applications & Storage) • Increased Life Time Of Client. (NO Moving Part ,Less Power Usage) • Provides Higher Security. (Authentication, virus protection, data on server, theft). • No Access To HDD, FDD, CD-ROMS. (Avoids Downloads, installations, Junk Data on to the HDD) • Thin Clients Are Virus Proof. (Since No OS And HDD Resides On It) • Reduced Power Consumption. • Centralized Backup. (Home Directory Mapping) • 286,386,486 PCs Can Be Converted To Thin Client And Can Work At Speed Of 800Mz Celeron Processor.

  9. Potential Disadvantages of Thin Clients • Entry costs are high for servers and installation expertise. • More bandwidth is required; multimedia, project-based learning applications run very slowly. • Thin-client doesn’t allow the flexibility to load software on the spot, constricting the “teachable moment.” • PC’s are coming down in costs, and many educators believe users need the fully-functioning capabilities of a desktop.

  11. Comparison cont.. Key usage factor/unmet need Thin Client PC's (User Benefit) (Centralised Approach) (Distributed Approach) Low total cost of ownership Yes Rapid Application Deployment Yes Support for windows applications and graphics Yes Yes Easy for end-users to use Yes Yes High security Yes Low initial cost Yes Support for legacy applications Yes Support for java applications Yes Yes

  12. What Services Can We Deliver Through Thin Clients. • Access To Internet Through Common Browsers Like IE. • Access To Subscription Database. • OPAC Browsing. • Microsoft Office. • Audio. • Several Application Software. • Printing.

  13. What Services Are Not Suitable For Thin Client • Streaming Video. • Video Games. • DVD Movies.

  14. Look & Feel…. Only restricted application can be used Internet Explorer

  15. What does a Thin Client Look Like? Conventional PC Thin Clients

  16. A librarian with good technical skills will be able to maintain the system, as long as there is support from a Microsoft Certified Professional if problems arise. • A Microsoft Network Administrator is needed to build a Thin client network. • Once the network is developed it take only one person to take care of (installation,hardware upgrade,Software upgrade,helpdesk) 100`s of PC.Common PC skill would be enough to manages the whole network What kind of expertise is needed to set up a thin client implementation like this?

  17. Citrix and Microsoft partnership WinFrame and MetaFrame National Semiconductor Sun Microsystems Wyse Technology Acer Compaq Dell IBM Gateway Major Developers of Thin Client Technology

  20. Growth OF Thin Client Popularity • Growth Of Last Years Market by 18% where else Desktop Pc`s remain flat round the world. • Standard Growth Of 3% Of Over All PC in market,expected to reach to 5% by next year. • If Technology is so good why do people don’t use it? • A Lot more people know about its existence.

  21. Summary • May extend Life of Current PC’s by 2-3years • Large upfront costs – Infrastructure and Network Costs (possibly Licensing) • Management, Support, Application Deployment, Security, etc. far easier • Will reduce Base Line Support costs over 3 to 5 years
