The correct answer is VoIP (Option B). VoIP uses the Internet to enable voice communication.
Step-by-step explanation:
The correct answer is VoIP (Option B).
VoIP stands for Voice over Internet Protocol, which uses the Internet to enable voice communication. It allows users to make phone calls using their Internet connection instead of using traditional telephone networks.
Unlike other options mentioned, such as TCP/IP, EFT, EDI, and PBX, which are all related to networking and electronic communication, VoIP specifically focuses on voice communication over the Internet.
The technology that uses the Internet to enable voice communication, as opposed to using the public switched telephone network (PSTN), is VoIP, which stands for Voice over Internet Protocol. VoIP technology allows people to make voice calls using a broadband Internet connection instead of a regular (or analog) phone line.
This technology converts voice vibrations to compressed digital signals that translate to Internet Protocol (IP) packets and then are transmitted over the IP network. The beauty of VoIP is that it can allow you to make a call directly from a computer, a special VoIP phone, or a traditional phone connected to a special adapter.
In addition, wireless hot spots in locations such as airports, parks, and cafes allow you to connect to the Internet and may enable you to use VoIP service wirelessly.
