DESIGN AND IMPLEMENTATION OF ORGANIZATIONAL WEBSITE
CHAPTER ONE
BACKGROUND OF THE STUDY
1.1 INTRODUCTION
Web Design is a process of conceptualization, planning, modelling, and execution of electronic media content delivery via internet in the form of technologies (such as mark languages) suitable for interpretation and display by a web browser or other web-based graphical user interfaces (GUIs). The intent of web design is to create a website (a collection of electronic files residing on one or more web servers) that presents content (including interactive features or interfaces) to the end user in the form of web pages once requested. Such elements as text, forms, and bit-mapped images (GIFs, JPEGs, and PNGs) can be placed on the page using HTML, XHTML, or XML tags. Displaying more complex media (vector graphics, animations, videos, sounds) usually requires plug-ins such as Flash, QuickTime, Java run-time environment, etc. Plug-ins are also embedded into the web pages by using HTML or XHTML tags. Improvements in the various browsers compliance with W3C standards prompted a widespread acceptance of XHTML and XML in conjunction with Cascading Style Sheets (CSS) to position and manipulate web page elements. The latest standards and proposals aim to leading to the various browsers’ ability to deliver a wide variety of media and accessibility options to the client possibly without employing plug-ins. Typically web pages are classified as Static or dynamic.
· Static pages don’t change content and layout with every request unless a human (web master or programmer) manually updates the page.
· Dynamic pages adapt their content and/or appearance depending on the end-users input or interaction or changes in the computing environment (user, time database modifications, etc.) content can be changed on the client side (end-users computer ) by using client-side scripting languages (JavaScript, Jscript, Action script, media players and PDF reader plug-ins, etc.) to alter DOM elements ( DHTML). Dynamic content is often compiled on the server utilizing server-side scripting languages (PHP, ASP, PERL, ColdFusion, JSP, Python, etc.). Both approaches are usually in complex applications. With growing specialization within communication design and information technology field, there is a strong tendency to draw a clear line between web design specifically for web pages and web development for the overall logistics.
