Demographics are the DNA of marketing: age, sex, income, profession, marital status, location, and so on.
Advertisers rely on demographics to help decide which sites are most likely to help them reach their specific audience. Knowing your audience demographic not only helps you sell ads, it also lets you know who your users are and what they want.
An Interstitial is a web advertisement that appears on its own page, typically in between “content” pages. Interstitials are typically not clickable (or are linked to the page you’d originally hoped to reach), but are usually buffered by a similar, smaller advertisement on the subsequent content page that allows you to investigate the advertiser’s product. By mid-1997, interstitials were at the top of every advertiser’s want list, but have lost popularity since then.
The hexadecimal (base 16) number system used for Web-page design consists of 16 unique symbols:0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C, D, E, and F.
For example, the decimal number 15 is equal to the hexadecimal number F. In HTML, an RGB

Black is the absence of all color and white is the presence of all color, so in hexadecimal, black is at the bottom of the system (no red, green, or blue:
and white is at the top (the maximum amount of red, green, and blue:
A router (not to be confused with a bridge) is a data network device that transfers data from one LAN to another. Routers can be hardware- or software-based, though larger applications and faster communication speeds all but require a hardware router. Routers are used in homes and offices with high-speed internet access such as DSL; they serve to connect the local LAN to the high-speed WAN operated by a service provider.
