Embedded web technology allows embedded systems to interface with users through a web browser on a standard computer. It was developed by NASA Lewis Research Center to reduce the cost of maintaining user interfaces for experiments on the International Space Station. The Tempest software, written for embedded real-time systems, allows an embedded web server to transmit web pages to a client browser's presentation layer. Embedded web technology works similarly to traditional web systems, but in a more restricted embedded environment.

- 3. Introduction • Embedded Web Technology is the merging of Embedded Systems with the World Wide Web. • It decreases the cost of developing and maintaining the user interface by allowing the user to interface to the embedded system through a web browser running on a standard personal computer.

- 4. Embedded system & Web technologies Embedded system • An embedded system is a microcontroller or microprocessor based system which is designed to perform a specific task Web technologies • Web technologies refers to the way computers/devices communicate. with each other using mark up languages Embedded Web Technology 4
- 5. History • EWT was developed by members of NASA Lewis Research Center. • It was modified in 2002 . Embedded Web Technology 5
- 6. Embedded web technology • Embedded Web Technology was developed for the Fluids and Combustion Facility (FCF) of the International Space Station (ISS) • One of the goals of the FCF is to be able to perform at least 10 investigations in each discipline per year for 10 to 15 years. • In order to meet this goal, it is important for the software to be adaptable to changing requirements. • In the event that the ISS decides to upgrade the laptop computer, the FCF software team will be required to modify existing user interface code for a new environment • The FCF software engineering team decided to write their own web server and this proved successful. The web server, known as Tempest Embedded Web Technology 6
- 7. Tempest software Embedded Web Technology 7 • The Tempest software, which was written by software engineers at the NASA Glenn Research Center, is a web server written specifically for embedded, real- time systems. • Tempest was originally written for the VxWorks ® operating system from Wind Rivers Systems, Inc. and then ported to the Java language so that it can run on any operating system that has a Java Virtual Machine
- 8. How it works? • The embedded Web technology works on the same principle as that traditional Web request- response systems. • Web pages from the embedded system (server) are transmitted to the Web browser (client) , which implements the user interface (Presentation layer).

- 9. Web server Environment Vs An Embedded, real-time Environment • A typical web server runs on a computer that is running a nonrealtime operating system. • The embedded, real-time environment is much more restricted. The system generally consists of an embedded processor running a real-time operating system and running a real-time application. Embedded Web Technology 9
- 10. Embedded Software These software-based applications are : • Database applications • Internet applications • Mobile office productivity tools • Personal applications Embedded Web Technology 20XX 10
- 11. APPLICATIONS • Space Communication • Biotechnology • Technology transfer and protocol • Education Embedded Web Technology 20XX 11
- 12. Advantages • The embedded system is easy for mass production. • The embedded system is highly reliable. • It has very few interconnections. • The embedded system is small in size. • The embedded system has less expensive. • It has fast operation. • It has improved product quality. • It optimizes use of system resources. • It has low power operation. Embedded Web Technology 20XX 12
- 13. Disadvantages • The embedded systems are hard for maintenance as it is use and throw device. • It has no technological improvement. • Less power supply durability if it is battery operated. • It has hard to take backup of embedded files. Embedded Web Technology 20XX 13
- 14. Conclusion Web technology in embedded application has distinct pros 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 this is vastly becoming an important tool in our lives. Embedded Web Technology 14
