Answer

Brief Explanations:

A VPN is a technology that connects two or more private networks over a public network (usually the Internet) to create a secure and private - like connection. It doesn't require a huge investment in Internet infrastructure for basic use. It can reduce costs in some cases by using existing public networks instead of dedicated private lines, and it is very useful for remote workers.
