The ‘banner’ advertising is the most common on the Internet, often used in advertisements for the dissemination of Internet sites that pay for their inclusion. It is designed to attract a user to a site through a link. Although all types of sites are likely to have banners, are the sites with higher traffic and content of interest to attract more investment from advertisers.
The banner images are usually developed in .jpg or .gif or animations in Java, Shockwave or Flash. A banner can have multiple dimensions, the most known of 468×60 pixels. These images often have an elongated, horizontally or vertically.
The banner is displayed every time a page that contains it is opened by the browser. This is technically defined as “printing.” Generally, clicking on the banner, the user is redirected to the page of the advertiser. The user click on the banner receives the technical name “click through”. In many cases, this redirection is managed by a server (central ad server).
And the ‘sign’ is something that implies a connection between itself and its object. A natural storefront signs bears a causal relation to its object – for instance, thunder is a sign of storm. A conventional sign signifies by agreement, as a full stop signifies the end of a sentence. (This is in contrast to a symbol which stands for another thing, as a flag may be a symbol of a nation).
