2. INTRODUCTION
The world we are living is becoming internet controlled day by day .
In this sense we should have some regarding embedded web technology(EWT)

3. Introduction to EWT
Embedded web technology is defined as the marriage of embedded system and world wide web

4. history EWT was developed by members of NASA Lewis Research Center
It was modified in 2002.

5. EWT- BASICS Embedded system Embedded web server Client server
HTML and XML

6. Embedded system
An embedded system is a computer system with a dedicated function within a larger mechanical or electrical system, often with real-time computing constraints

7. Embedded web server
Embedded Web Server Technology is most evolving technology for Internet Devices. There are many application areas including internet devices, telecommunication devices, measuring instruments and lots of consumer electronics

8. Client server model
Client—A logical entity that initiates a request for data or for an action to take place..
Server—A complementary logical entity to a client.

9. HTML and XML
HTML
Hypertext markup language (HTML) is a language used to describe a webpage.
When a web browser receives content that is HTML it will try to render the content into a web page. Similar to XML, HTML is made up of tags, but unlike XML, HTML defines what types of tags are acceptable.
XML
Extensible markup language (XML) is a structure for text so that information can be easily stored and transmitted through a web service.
Although the L in XML stands for language , but it is not a programming language. XML is a popular content choice because it is human readable, and translates easily to other programming languages.

11. Working of ewt
The embedded Web system works on the same principle as that traditional Web request-response systems.

12. Web pages from the embedded system (server) are transmitted to the Web browser (client) , which implements the user interface (Presentation layer).
Web-enabled devices use the HTTP (Hyper Text Transfer Protocol) standard protocol to transmit Web pages from the embedded system to the Web browser , and to transmit HTML (Hyper Text Markup Languages) form the data from the browser back to the device.
The HTTP protocol engine takes the request from the Web browser and sends it on the TCP/IP. The HTTP protocol Engine parses the request and sends it to the embedded application for processing.
After producing the results , the embedded application generates the HTML code and feeds it to the HTTP Engine , which sends it back to the client using TCP/IP. 

13. Advantages Utilizing Embedded Web Technology has several advantages
Web browser does not store the applet permanently
. User interface software upgrades
Provide output to the remote user in any format .

14. APPLICATIONS OF EWT Traffic monitoring Video monitoring
Power infrastructure monitoring
Add slides for each example and explain them . If limitation of time then explain atleast one preferably traffic monitoring system

15. CONCLUSION
Web technology in embedded applications has distinct advantages over legacy and custom communication mechanisms due to the scalability and security. The amount of knowledge and skills needed to create a web application may be large. However embedded technology is vastly becoming an important tool in our daily lives
