ITPEC IP April 2025 — Question 34 of 100
VoIP — Voice over Internet Protocol carries voice communication over IP networks.
A VoIP application digitizes speech, sends it as packets over the Internet, and reconstructs the audio for the other participant. When both parties use a compatible application, they can make voice calls without the call being carried end to end as a traditional telephone circuit.
Answer (d)
Why not others:
- (a) MVNO is a mobile service provider that uses another operator's radio network
- (b) NFC is very-short-range wireless communication for uses such as payments
- (c) NTP synchronizes clocks over a network
Key rule: VoIP transports voice via IP packets; the other acronyms describe a carrier business model, short-range communication, and time synchronization.
