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.

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.
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.
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
