How does global network infrastructure work and what are the design principles on which it is based?

Global network infrastructure operates through a complex system of interconnected data centers, servers, and communication networks that facilitate data exchange across the globe. It relies on key design principles such as redundancy, scalability, and interoperability, ensuring that networks can handle increased traffic and remain resilient against failures. Additionally, protocols like TCP/IP govern data transmission, while elements such as routing and switching manage the flow of information. This infrastructure underpins the internet and supports various services, from cloud computing to streaming and e-commerce.
