What is Full Root Access - VPS ?
A virtual private server (VPS) is a physical server that has been split into several virtual machines by software. Each of these divisions acts as an autonomous dedicated server. The physical resources such as RAM, CPU and disk space are still shared, but each VPS acts independently of the others. Each VPS can even have a different operating system and can be configured any way you want. The central asset of VPS is that it lets each VPS administrator have access to the root level of his virtual server.
This Full Root Access allows a VPS to work as same functionality as of a Dedicated Server.
