Which of the following is a common service provided by VoIP?

Voice communication is a primary service provided by Voice over Internet Protocol (VoIP) technology. VoIP enables users to make phone calls using the internet rather than traditional telephone lines, converting voice signals into digital data packets. This method is not only cost-effective but also offers enhanced features such as call forwarding, voicemail, and conference calling, which are essential for both personal and business communication.

Understanding VoIP's core function as a means of facilitating voice conversations is crucial as it distinguishes this technology from other options. While video streaming, email communication, and data storage solutions are essential digital services, they do not align with the primary function of VoIP, which is focused solely on enabling voice interactions. Consequently, voice communication stands out as the correct answer, highlighting VoIP's role in transforming how we conduct conversations in a connected world.
