The technology that allows for real-time communication across global distances through the Internet is known as VoIP (Voice over Internet Protocol). VoIP converts voice signals into digital data packets transmitted over the Internet, enabling voice calls, video conferencing, and other communication services. This technology eliminates the need for traditional telephone lines, reducing costs and improving accessibility. VoIP applications, such as Skype and Zoom, have become integral to modern communication, allowing users to connect instantly regardless of location while providing additional features like screen sharing and recorded sessions.
