Internet topology

Internet topology refers to the physical and logical structure of how devices, such as computers and servers, are connected and communicate. Physically, it involves cables, routers, and data centers forming a network of pathways. Logically, it describes how data routes between devices, often through layered systems like local networks, internet service providers, and global infrastructure. Think of it as a vast web of interconnected roads and highways that allow information to travel quickly across the world. Understanding this structure helps improve network efficiency, reliability, and security.
