Bandwidth
The range of frequencies a transmission line or channel can carry: the higher the frequency the higher the bandwidth and the greater the information carrying capacity of a channel. Bandwidth is most accurately expressed in cycles per second, or hertz (Hz), which measures the amount of information that can flow through a channel. But, it's also common to use bits or bytes per second instead.
IP Address
When you get on the Web, your computer is assigned an IP address. This is a number that looks like 192.168.123.100. These numbers belong to a host name, for example AOL or your local ISP or company where you work (if they have their own server). If you access the Internet via a dial-up service, your service provider assigns you a different temporary IP address every time you log on. If you access the Web via cable modem or DSL, your IP address remains static - it is always the same one.
Keyword Prominence
Denotes how close to the start of an area of a Web page that a keyword appears. In general, having the keyword closer to the start of an area will lead to an improvement in the search engine ranking of a page. However, in some cases, having the keyword in the middle or the end of an area may lead to an improvement in the search engine ranking of the page.
