In the web hosting industry, a dedicated server is usually defined as the rental and exclusive use of a computer that includes a web server, related software, and connection to the Internet, located on-site, within a webhosting company's premises.A dedicated server is a single computer in a network reserved for serving the needs of the network. For example, some networks require that one computer be set aside to manage communications between all the other computers. A dedicated server could also be a computer that manages printer resources. Note, however, that not all servers are dedicated. In some networks, it is possible for a computer to act as a server and perform other functions as well.
