The term "disk space" is oftentimes identified as "disk quota" or "data storage", however all these words refer to the exact same thing - the amount of info that you can upload to a hosting account. The overall size of the things you have is determined by accumulating the storage space used by the overall content within your account, the most obvious being the types of files you upload. Two more things are often forgotten by various people, though - e-mail messages as well as databases. Larger attachments or databases of big script-driven sites will often take a lot of disk space as well. To employ a more recognizable analogy, the hard drive space of your laptop or computer is taken not only by files that you download, but also by documents you write as well as software programs you install. Similarly, various things are counted for the hdd space your data needs on a website hosting server, not only the uploads.
