Disk space is basically the storage of your files, while (monthly) bandwidth is the space needed to actually show your files on the Internet.
Disk space and bandwidth are both important in the existence of your website. No more disk space means you can't upload new files, and no more bandwidth means that no one can see your website (for that month).
Disk Space Amount: The default set up for each hostee is around 20-50 MB of disk space, but can be adjusted. Please contact me if you need to modify your disk space.
Monthly Bandwidth Amount: Hostees under shared hosting all share a monthly bandwidth of 50 GB. This includes my websites. Hostees under reseller hosting are given their own monthly bandwidth of 7 GB.
As of August 2015: The company that host's Shukuya.com, E-starr, now provides unlimited bandwidth to its clients. This means that while there is a "listed limit," if you go over the limit the site won't be suspended.
Viewing Disk Space
* Shared Hostees: The function to view disk space on your subdomain is available only if the FTP program you are using allows it. Shared hostees will not have access to an online website manager to check space usage.
** Reseller Hostees: the "disk space" function is available on your cPanel account. cPanel will allow you to view the total amount of space used, as well as a breakdown of the amount of space used by folders/files.
