The fundamental technology underlying digital communications is the Internet Protocol (IP). This protocol governs the format of data packets and facilitates their transmission across networks. IP allows devices to communicate with each other by assigning unique IP addresses, ensuring that data can be routed accurately between senders and receivers. Moreover, various protocols, such as Transmission Control Protocol (TCP), work alongside IP to ensure reliable data delivery. The synergy of these technologies is vital for enabling a seamless flow of information in today's interconnected world.
