Which technology allows phone calls to be made via broadband internet?

1. Satellite Communication

2. Traditional Landlines

3. Voice Over Internet Protocol (VOIP)

4. Cellular Networks

The correct answer is: Voice Over Internet Protocol (VOIP)

Voice Over Internet Protocol (VOIP) is the technology that enables phone calls to be made using broadband internet. This system works by converting voice into digital packets, which are then transmitted over the internet, allowing users to make voice calls through an internet connection instead of traditional phone lines. VOIP offers advantages such as lower costs, flexibility in communication, and the ability to integrate with various online services and applications. In contrast, traditional landlines rely on physical wiring and circuit-switched technology to establish voice calls, which is not conducive to internet-based communication. Cellular networks, while allowing mobile phone communications, do not rely on broadband internet to facilitate calls; instead, they use radio signals and cellular towers. Satellite communication involves transmitting signals from satellites but is not typically used for standard phone calls over broadband. Thus, VOIP stands out as the technology specifically designed for internet-based communication.
