Third-party ad servers allow advertisers to control the rotation and distribution of their adverts by distributing them from a single central source, or server, across a number of different web domains.
A servers in computing is a piece of hardware or software (computer program) that offers functionality to other programs or devices, often known as "clients." The client-server model is the name given to this architecture. The functions that servers can offer are frequently referred to as "services," such as executing computation for a client or distributing data or resources among several clients. A single client can use several servers, and a single server can serve many different clients. A client process may operate on the same device or it may establish a network connection with a server running on a different device. Database servers, file servers, mail servers, print servers, web servers, game servers, and application servers are examples of typical servers.
The request-response model is typically the one that implements client-server systems the most frequently (and is generally associated with it).
