Ad server, online advertising network working system

A third-party server that stores ads and delivers them to web site visitors, normally used by an online advertising network. Having ads on a seperate server allows publishers to feature ads on their sites without having to store ads on their own servers. They also allow ad networks to control the distribution of the ads they are handling for cients. Adware is normally used to record ad server activity. Publishers should be aware, however that an ad server is running slowly, or the ads are to large, the downloading ads could cause the web site itself to download slowly also. Users can see if a web site is running adware by looking at the status bar at the bottom of thei browser. This shows the URL of where content is being downloaded from. Normally this will be the url of the website itself, but it could also feature the URL of the ad server distributing the ads.
