A server space provider is an individual, company, or organization that provides storage space on a server for Web pages, usually for a charge. Some independent access providers and online services provide a limited amount of free space for Web pages (for example, one megabytes of hard disk storage).
Note that not all access provider offer server space. And many server space providers do not provide access. Server space and access are two different services.
Relative to other costs of developing a Web site, the cost of server space is usually small. A new trend on some sites, however, is to charge for the amount of traffic your pages get rather than the space they use. This is because server space is relatively cheap compared to the administrative costs of managing a busy site for someone.
