The technology that provides the foundation for the Internet is the Transmission Control Protocol/Internet Protocol (TCP/IP). This set of communication protocols enables devices to connect and communicate over the Internet. TCP ensures that data is transmitted accurately and in the correct order, while IP is responsible for addressing and routing packets of data to their intended destinations. Together, TCP/IP enables various types of devices, including computers, smartphones, and servers, to exchange information seamlessly. The widespread adoption of this protocol suite has facilitated the exponential growth of the Internet, making it an essential component of modern networking and communication.
