In the web hosting world, overselling means advertising attributes which a client will pay for, but can’t really get. Some of the features of a given website hosting solution can belong to this category - disk storage, monthly traffic, database storage space, and so on. A package could come with unrestricted disk space, as an illustration, but almost all hosting service providers make accounts on just a single server that can have only so many hard drives and since all the customers upload content, there won't be any space left on the server sooner or later or there will be some hidden quotas to guarantee that each and every user has their share, although everybody has paid for unrestricted space. As most internet hosting Control Panels are intended to work on one server, lots of companies have no choice but to oversell, that's nothing else but tricking their clients.
