===== A Glossary of Terms Used in Internet and Web Applications Technology ===== Welcome to this glossary of terms that are used in the Internet and Web Applications Technology. The aim of this glossary is to define all the technical terms and networking jargon is used in my various modules and have provided links to further information where appropriate. ===== Help Needed ===== There are an awful lot of terms to be defined and I need your help! This glossary is a [[glossary:wiki]] which means that you can make //your own contributions// to it! If you find a page with a red link like [[red link|this]], it means that I have identified a term that needs to be defined but I haven't gotten around to providing a definition yet. You can help by following the link to the page that says **This topic does not exist yet**, clicking on the tab labelled **create this page** and providing a definition. All you need is an account which you can request by registering with this [[glossary:wiki|wiki]]. To define a term, use the lecture notes or try using the special Google search ''define: //term//'' to find a definition. For example try [[google>define: internet]]. If there is a term that you think should be defined, edit this page and add it to the list of terms. If you think you have a better definition than the one that's here, or you want to write your own definition for any of the undefined terms, please be my guest. If you would like to experiment with the [[glossary:wiki]] prior to making a contribution, please use the [[playground:playground]]. If you'd just like to comment on any of the terms that I define, you can do that also using the associated discussion page. I hope and expect that this glossary will become a very useful resource for my current and future crops of students and look forward to seeing your contributions. ===== The Alphabetical Index ===== Each term defined in this glossary has a corresponding page in the wiki and should be listed in the page index below. If you add new terms, please add an entry to the index. The format is fairly self-explanatory.
