What does VoIP stand for?

VoIP stands for Voice over Internet Protocol, which is a technology that enables the transmission of voice communications and multimedia sessions over the Internet. This protocol allows users to make phone calls using their internet connection instead of traditional telephone lines, which can lead to cost savings and greater flexibility. VoIP converts sound into data packets, which are then sent over the internet to the recipient, where they are converted back into sound.

This technology has become increasingly popular due to its efficiency and the ability to integrate with various digital media and services, such as video calls and messaging, providing a comprehensive communication solution. The other options listed do not accurately represent the technology or its function, as they refer to different types of data transmission or concepts that do not exist in the context of VoIP.
