These are both control panels or if you like admin areas for your web hosting account. Not to be confused with the admin area of your website.
These differ from your websites admin area.
In Cpanel, you can do things like setting up new email accounts, view statistics on your site such as visitors and where they come from. There are many functions you can perform in Cpanel but they relate mostly to your hosting account and not your site.
The Golden rule when in C Panel is if you do not understand it don’t change it. We are always on hand to answer any questions you may have so just pop in a support ticket if you are unsure.
All our super fast web hosting accounts use the awesome Cpanel.
