On the Internet, a virtual server is a server (computer and various server programs) at someone else’s location that is shared by multiple Web site owners so that each owner can use and administer it as though they had complete control of the server. Some Internet service providers (ISPs) offer a virtual server service instead of, or in addition to, virtual hosting. Using a virtual server, a company or individual with a Web site can not only have their own domain name and IP address, but can administer their own file directories, add e-mail accounts and address assignments, assign multiple domain names that resolve to a basic domain name without involvement from the ISP, manage their own logs and statistics analysis, and maintain passwords. Users of a virtual server, however, do not have to manage the hardware aspects of running a server and effectively share the cost of expensive line connections to the Internet.
