(American Computer Technology)
What Is A Network?
Web and Information
Ü A group of computers working together.
Ü Peer to Peer Network, Client/Server, Internet, etc.
Ü Most common Technology in Networking:- Client/Server .
What are Different Types
Ü Client:- is a computing device/software that retrieves information
from a server.
Ü 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.
Ü 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?
Ü An emaciated Library Patron.
Ü A Program To Purge Expired Patron.
Ü An Anorexic Library Budget.
So Then What Exactly Is A Thin Client?
Ü A Hardware/Software that runs application on a server, not on
Ü Key strokes and mouse click are sent over network to the server
to process and give back the result…… (screen).
Ü Clients can be a low powered PC or a Thin client device.
Ü They Don’t Have HDD, FDD, CDROMS, Cooling Fans, Very Low
What Makes A Thin Client
Ideal For 30-40 Clients running common OPAC`s,Internet,Office software,etc
• Power Full Server with • Citrix Meta Frame
Ram,10 MBps Network. software
(Compaq Proliants, HP Netserver • Windows 2000/2003
& IBM NetFinity )
• Thin Clients
(IBM,Neoware,WYSE, SUN , OR
OR • Windows
• A Low Processing PC. CE,XP,NT.
How Does A Thin Client
Ü About 1/3 Size Of PC.
Ü Works In A Same Way And At Same Speed As Desktop PC.
Ü Supports GUI And Windows Environment.
Ü Can Be Configured On As Low As 16Mb Of RAM.
Ü Same Feel As Working On Any Windows Based OS.
Ü Remote Computation….Server Takes Care Of All The Processing.
Ü Works On either Citrix`s ICA Or Microsoft's RDP Protocols (Both
Require Only 20Kbps Speed Over Network To Work).
Ü 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
Advantages Over Desktop Pc`s
Ü Dramatically Decreases The TCO by 54% to 57%.
Ü Decreases IT Cost By 80% Through Reduced Staff And Centralized
Software Management. (Does not Crash, NO Help DESK)
Ü Greatly Simplifies The Software Upgrade Over The Network.
Ü Eliminates The Hardware Upgrades On Client Side.
Ü Increases End User Productivity. (Limited Access To Authorized Applications & Storage)
Ü Increased Life Time Of Client. (NO Moving Part ,Less Power Usage)
Ü Provides Higher Security. (Authentication, virus protection, data on server, theft).
Ü No Access To HDD, FDD, CD-ROMS. (Avoids Downloads, installations, Junk Data on to the HDD)
Ü Thin Clients Are Virus Proof. (Since No OS And HDD Resides On It)
Ü Reduced Power Consumption.
Ü Centralized Backup. (Home Directory Mapping)
Ü 286,386,486 PCs Can Be Converted To Thin Client And Can Work
At Speed Of 800Mz Celeron Processor.
Potential Disadvantages of
• Entry costs are high for servers and installation
• 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

What kind of expertise is needed to set up a
thin client implementation like this?
•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
•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

Growth OF Thin Client
•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.
• 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
