Each time you upload a file on a web hosting server, it will take a certain amount of storage space on the hard disk drive dependent on its size. In the event that you operate a script-driven internet site which stores its data 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 more comments people share, the larger the database gets. E-mail messages, in particular ones using attachments, also need some space in the site hosting account. The disk space quota you will get with each shared website hosting supplier is the full amount of data you can have at any moment, and this includes website files, e-mail messages and databases. Likewise, a personal computer has a hard drive and the computer software installed on it plus all docs and music files that you make or download require some storage space, which can't exceed the full capacity of your hard disk drive.
