The World Wide Web (WWW) has become the primary means by which we conduct searches and perform billing transactions—events that can only occur with the support of specific applications. The purpose of this course is to introduce you to the design and development of such applications. This course will expose you to the basic fundamentals of the Internet and Web protocols, the different architectures that Web-related applications use, and the programming languages that enable the development of Web applications, placing particular emphasis on JavaScript, HTML, XML, AJAX, and Java Server Pages (JSP). We will also cover matters of security and reliability in the development of web applications via the use of transport encryption and authentication.
