8.What is a virtual private network? Why is it called“virtual”?
A Virtual Private Network (VPN) is a technology that creates a secure and encrypted connection over the internet, allowing users to access network resources and services as if they were directly connected to a private network. The term "virtual" refers to the fact that the network is not physically separate, but rather is created through the use of software and encryption protocols.
In essence, a VPN creates a secure tunnel between two devices, allowing all the traffic to flow through that tunnel. The tunnel is encrypted, so all the data passing through it is protected from interception or eavesdropping. This is particularly useful for users who need to access resources or services that are restricted to a particular geographic location, as the VPN allows them to appear as if they are located in a different country or region.
