Course Justification Internet technology has now become dominant factor in business, academia, and everyday life. E-commerce and e-services are now fueling market change, with practically any business anyplace nurturing its equivalent on the internet. The Internet carries a vast range of information resources and services, such as the inter-linked hypertext documents of the World Wide Web (WWW) and the infrastructure to support electronic mail. The Internet has changed the way companies do business, consequently increasing the demand for skilled web developers and administrators. This course will provide the students the opportunities to enhance their Internet skills. It will also allow them to acquire skills necessary to design sites that communicate effectively which are accessible to the widest audience and are attractively designed. 1

Course The main objectives of this course are to enable students to understand the key design principles used to build the internet and the details of internet protocol and also provide students with a fundamental understanding as to how an XHTML-compliant web site is developed, implemented, and maintained. At the end of this course, the students should be able to: (i) demonstrate an understanding of the design and construction of internet services; (ii) write program in X-HTML, Cascading Style Sheets and JavaScript, without the aid of web-development software; (iii) describe the operations of internet protocols and develop their own internet applications; (iv) design sites that communicate effectively which are accessible to the widest audience and are attractively designed; and (v) explain the underlying technological concepts that enable the Internet to work. Course Requirements Students are expected to attend 75% of the classes before they can sit for the examination and participate very well in the class. Students are also expected to bring their laptops to class so as to be able to work through examples in the notes during the lectures practically.
