IP Address
An IP Address is a unique identifying number used to locate data across the web.
A virtual private server allows multiple websites to use the same server, but avoids the pitfalls of shared hosting because the resources are partitioned so each website is independent of each other.
“The most common type of VPS is a web host. Many web hosting companies offer VPS hosting solutions as an alternative to shared hosting and dedicated hosting. A VPS sits in between the two options, usually in both performance and price. Like a shared host, a VPS may share the resources of a physical machine with other hosting accounts. However, a VPS is custom-configureable like a dedicated hosting solution it is isolated (“private”) from other accounts.”
