Thin Client Presented by.. Hetul Patel Network Engineer (American Computer Technology)
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 .
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.
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.
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
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.
Who are the Main Players ? • Microsoft – NT/2000/2003 Terminal Services (RDP)Remote Desktop Protocol • Citrix – MetaFrame(ICA)Intelligent Console Architecture ICA RDP
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.
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.

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.
What Services Are Not Suitable For Thin Client • Streaming Video. • Video Games. • DVD Movies.
Look & Feel…. Only restricted application can be used Internet Explorer
What does a Thin Client Look Like? Conventional PC Thin Clients
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?

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.
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
