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
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
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.
what makes a thin client network
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
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

advantages over desktop pc s
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
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 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 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

growth of thin client popularity
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
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
