In the hosting world, overselling means advertising benefits which a client buys, but can’t really take advantage of. Some of the features of a given web hosting solution can fall under this category - HDD storage, monthly traffic, database storage space, and many others. A package may come with limitless disk space, as an illustration, however the vast majority of hosting providers create accounts on a single server that can have a limited number of hard disks and due to the fact that all of the customers upload content, there will be no space left on the server eventually or there'll be some secret quotas in order to ensure that each user has their own share, regardless that everyone has paid for unrestricted space. Since most hosting Control Panels are meant to work on one server, many companies don't have a choice but to oversell, that is nothing else but deceiving their customers.
