When you upload information on a web hosting server, it takes some space on the hard drive dependent on its size. When you have a script-driven website which keeps its information in a database, you will need more disk space, the more people make use of it. To give an example, if you have a message board, the greater number of opinions people leave, the bigger the database will be. Email messages, in particular ones using attachments, also take some space in the web hosting account. The hard disk space quota that you receive with your cloud web hosting provider is the total amount of information you may have at any given moment, and this contains site files, messages as well as databases. Similarly, a PC has a hdd and the computer programs installed on it along with all of the documents and music files that you generate or download require storage space, which cannot exceed the overall capacity of your hard disk drive.
