B.

C.

D.
Virtual Private Networks

Explanation:
Virtual Private Network (VPN) connection is a link in which the private data is
encapsulated and encrypted. A VPN is the extension of a private
network that encompasses links across shared or public networks, like the Internet. A VPN enables
you to send data between two computers
across a shared or public internetwork in a manner that emulates the properties of a point-to-point
private link. To emulate a private link, the
data being sent is encrypted for confidentiality. Packets that are intercepted on the shared or public
network are indecipherable without the
encryption keys.

VPN connections allow users working at home or outside location to obtain a remote access
connection to an organization server using the
infrastructure provided by the Internet.
