- ADSL -- (Asymmetric Digital Subscriber Line)
-
A DSL line where the upload speed is different from the download speed. Usually the download speed is much greater.

- Ajax -- (Asynchronous JavaScript and XML)
-
A way of including content in a web page in which javascript code in the web page fetches some data from a server and displays it without re-fetching the entire surrounding page at the same time (hence the 'Asynchronous')
Often (but not always) the data fetched by the javascript code is in XML format.
It is common for Ajax applications to update the Ajax content multiple times without the surrounding page needing to be updated even once.
A simple example of Ajax would be a weather-forcast box in the middle of a web page. Ajax could be used to populate the box every 5 minutes without needing to refresh the surrounding page.
- Bandwidth
-
How much stuff you can send through a connection. Usually measured in bits-per-second (bps.) A full page of English text is about 16,000 bits. A fast modem can move about 57,000 bits in one second. Full-motion full-screen video would require roughly 10,000,000 bits-per-second, depending on compression.

- Blog -- (weB LOG)
-
A blog is basically a journal that is available on the web. The activity of updating a blog is "blogging" and someone who keeps a blog is a "blogger." Blogs are typically updated daily using software that allows people with little or no technical background to update and maintain the blog.
Postings on a blog are almost always arranged in chronological order with the most recent additions featured most prominently.
It is common for blogs to be available as RSS feeds.
