[A] My network
[B] Virtual Private Network
[C] Social Network
[D] None of the above
Show Answer
Correct Answer: B [Virtual Private Network ]
Notes:
A virtual private network (VPN) extends a private network across a public network, and enables users to send and receive data across shared or public networks as if their computing devices were directly connected to the private network. Applications running on a computing device, e.g., a laptop, desktop, smartphone, across a VPN may therefore benefit from the functionality, security, and management of the private network. Encryption is a common, though not an inherent, part of a VPN connection.
