The technology that facilitates real-time communication over the internet is primarily Voice over Internet Protocol (VoIP), which allows users to make voice and video calls using internet connections instead of traditional phone lines. Other key technologies include webRTC (Web Real-Time Communication) and various messaging platforms that enable instant messaging and file sharing. These technologies enhance connectivity, enabling users to communicate seamlessly across distances. As a result, they support personal interactions and business communications, making global collaboration more efficient and accessible.
