Question

Quizplus · Accepted Answer

Only a virtual private network (VPN) uses encryption to protect confidentiality of transmission. Public networks, such as the internet, are not encrypted and therefore not secure. Private networks may or may not use encryption depending on their configuration. VoIP (Voice over Internet Protocol) is a technology used for making phone or video calls over the internet and does not necessarily involve encryption.
