Which of the following best describes VoIP?

VoIP, or Voice over Internet Protocol, is best described as a technology that enables voice conversations to occur over the Internet rather than through traditional telephone lines. This system takes analog voice signals and converts them into digital data packets, which can then be transmitted over the same networks that carry internet traffic. This method not only enhances the flexibility and efficiency of voice communication but also often reduces costs significantly compared to traditional telephony.

By leveraging the Internet, VoIP allows users to make calls globally without the constraints of geographical boundaries or high long-distance charges associated with landline calls. VoIP services can be used for various communication purposes, including both voice calls and video conferencing, making it a versatile application in both personal and professional settings.
