Anytime you upload a file on a web hosting server, you will need an amount of storage space on the hard disk drive depending on its particular size. When you operate a script-driven site which stores its information in a database, you will need more space, the more people work with it. To give an example, if you have a discussion board, the greater amount of responses people leave, the bigger the database will get. E-mail messages, in particular ones using attachments, also require some disk space in the website hosting account. The hard disk space quota that you receive with any web hosting provider is the overall amount of info you can have at any given moment, which consists of web site files, messages and databases. Likewise, a home PC has a hard drive and the computer software installed on it together with all of the documents or music files that you make or download take some storage space, which cannot surpass the full capacity of your hard disk.
