ICT and VoIP communication – UGC NET Question

Voice over Internet Protocol (VoIP) converts voice signals into digital packets that are transmitted over IP networks. This enables cost-effective voice communication and integration with other data services. Applications like internet calling and video conferencing rely heavily on VoIP technology. Therefore, the communication method described in the stem is VoIP.

Option A:
Option A, circuit switched telephony, refers to traditional public switched telephone networks that establish dedicated circuits for calls rather than using packet networks.

Option B:
Option B is correct because the full phrase voice over internet protocol precisely denotes transmitting voice using IP, which matches the description.

Option C:
Option C, fax over copper, would be an older method for sending documents over telephone lines and does not capture the move to IP networks.

Option D:
Option D, satellite broadcasting, is used to transmit television or radio signals and is not specific to voice calls over IP.
