What is Linux Root Directory & root folder?

What is Linux Root Directory & root folder? ***************************************************** Hi Guys, The root directory   contains all other folders in the  drive  or folder, and can, of course, also contain  files . You can visualize this with an upside-down tree where the roots (the root folder) are at the top and the branches (sub folders) fall below; the root is what holds together all of its lower items. The root folder, also called the  root directory  or sometimes just  the root , of any   partition  or folder is the "highest" directory in the hierarchy. You can also think of it in general as the start or beginning of a particular folder structure. In a  computer   file system , and primarily used in the  Unix  and  Unix-like   operating systems , the  root directory  is the first or top-most  directory in a hierarchy. It can be likened to the trunk of a  tree , as the starting point where all branches originate from. The  root file system

Predictive dialers are very easy software for call centers, they manage time and resources perfectly. Sometimes setting this open-source software becomes very hectic especially for  Newbies , that's why there’re some good  VoIP service providers  who can set this up for you on their hosted server and all you need to do is use its awesome features. Is one of the most complete dialer solutions for call centers available. This can allow you to configure anything from outbound/inbound, IVR settings, predictive dialer options, manual dialing, etc. To me one of the most complete I've seen, not to mention can give you the ability to configure the whole darn thing to your spec
