What is a Virtual Private Server (VPS)?

A Virtual Private Server is a virtual dedicated machine that resides on a computer that serves many websites. Each virtual server has its own operating system and a hosting software. The Virtual Machine will have limited access to memory and storage attributes of its physical server. Thus, users who have a website in a VPS are completely unaware of other websites hosted by its physical server, making it a private or dedicated server.
Owning a VPS has its own advantages. Firstly, users have full authority to access their Operating system. Also, a user can host multiple websites in the VPS, which could target different customers.
