The Internet serves as the overarching connectivity backbone, enabling the exchange of data between disparate systems, entities, and nodes. It operates across a global federation of autonomous systems and networks, facilitating seamless interaction. As a conceptual infrastructure layer, the Internet supports communication channels, application integrations, and service delivery mechanisms, ensuring scalability, resilience, and ubiquitous access. It interconnects stakeholders, systems, and processes, acting as a crucial enabler of distributed ecosystems and collaborative services.
