What is a Virtual Private Server?

A Virtual Private Server (VPS) is an entire operating system that runs within another operating system. It will share system resources like the CPU and RAM with other users but the resources are allocated in such a way that you cannot tell that the system has anyone else on it, much like a dedicated server. So resources are usually setup in such a way that each hosting client is only allowed to use an allocated percent, meaning that resources assigned to you will always available to you.

Introduction

A tunneling protocol is a network protocol which encapsulates a payload protocol, acting as a payload protocol. It is the process of putting one packet inside another.
