In the Internet hosting world, overselling means advertising benefits which a client pays for, but cannot really get. Several of the options of a given web hosting plan can fall under this category - hard disk storage, monthly traffic, database storage space, etc. A solution may come with limitless disk space, as an illustration, however a lot of hosting providers generate accounts on just a single server which can have a limited number of hard drives and considering the fact that all customers upload content, there won't be any space left on the server at some point or there'll be some secret quotas so as to make sure that every user has their own share, regardless that everybody has paid for unlimited space. As most internet hosting Control Panels are developed to work on one server, a lot of providers don't have any choice but to oversell, which is nothing else but tricking their clients.
