Anytime you upload a file on a web hosting server, it will take some storage space on the hdd dependent on its size. If you have a script-driven website which keeps its data in a database, it will take more space, the more people use it. To give an example, if you have a discussion board, the greater number of opinions people share, the greater the database gets. E-mails, especially ones having attachments, also need some space in the website hosting account. The HDD space quota that you get with each shared website hosting supplier is the total amount of info you may have at any given moment, which features website files, email messages plus databases. Likewise, a personal computer has a hard drive and the computer programs installed on it as well as all docs and / or music files that you generate or download require some storage space, which cannot surpass the overall capacity of your hard disk.
