The term "disk space" is sometimes labeled as "disk quota" or "data storage", however all these words refer to the very same thing - the volume of info that you are able to upload to a cloud website hosting account. The full size of the things you have is calculated by accumulating the storage space used by the entire content in the account, the most obvious being the types of files you upload. Two more things are usually ignored by a lot of people, though - emails and also databases. Big attachments and databases of huge script-driven sites can often use a lot of storage space too. In order to use a more recognizable analogy, the hard drive space of your computer is taken not only by files that you download, but also by docs you create as well as programs you add. Similarly, numerous things are counted towards the hdd space your data takes on a web site hosting server, not just the uploads.
