The term "disk space" may also be called "disk quota" or "data storage", yet all these terms refer to the very same thing - the volume of info that you can upload to a website hosting account. The overall size of the things you have is determined by accumulating the storage space consumed by the content within the account, the most obvious being the files that you upload. Two other things are generally forgotten by a lot of end users, though - email messages and also databases. Sizable attachments and databases of large script-driven sites will often require a lot of storage space too. In order to use a more recognizable analogy, the hdd space of your computer is used not just by files you download, but additionally by docs you make as well as programs you add. Likewise, various things are counted towards the disk space your content takes on a web site hosting server, not just the uploads.
