Windows over Web
Windows Over Web (WOW) or the thin client technology brings to the front, a new approach to program and application development. The technology is known as "thin client" technology as it reduces the software resources and computer hardware needed at each individual desktop.

The Understanding
Thin clients use centralized software provided over internal networks to serve a combination of PCs, Windows-based terminals and other network computing resources. Cost savings also result from less frequent desktop servicing requirements caused by software and hardware conflicts or installation problems.

WOW technology greatly helps remote agents and home based support centers. With secure applications, employees can work from remote offices and from the convenience of their homes using the same applications that are running in the office. Thin client technology helps enterprises:

• Reduce costs
• Increase security
• Achieve quick deployment
• Improve manageability

It offers a viable alternative to the desktop PC for many, making access to business data and applications easy, secure and affordable. With a thin-client system, the client sends keystrokes and mouse movements to the server over the network or dial-up connection, and the server sends back changes in the display. Any PC can be a client, but because very little processing is performed at the desktop, businesses can also use low-cost terminals that have no moving parts (no hard drive) and a generally small amount of memory (RAM). Since each client is just a terminal, all data and settings-and even the applications-are on the server. To back up everything for all the users, the organization only needs to back up the server. And for disaster recovery, backups are easier and more centralized, making it easier to take the backups off-site.

Features of WOW/Thin Client Technology

• Web applications can be developed without a browser
• Traditional programming techniques can be used with thin client software
• Server based computing toolkit for defining PC Windows
• Server applications written in C, Cobol, or other compile language
• Thin client software can communicate with one or more server applications
• Separate WINDOWS client running on each user PC.
• Thin client software does not need to be updated when server application changes
• Server based computing API set of functions to control the display of Windows
• Thin client software functions with Linux windows software
• Thin client software functions with Unix windows software
• Full graphics and multi-media support.
