Dell publishes an explainer covering TCP/IP, DNS, routers, fiber and CDNs, plus a simple connection self-test.
Dell published an explainer on how the internet works, from physical infrastructure to the protocols that keep data moving. It covers how the internet moves data in small packets using TCP/IP so information can route around congestion and failures.
It describes the hardware backbone of routers, switches, servers and fiber links that connects global networks.
It then explains how DNS, IP addresses and content delivery networks work together to locate content and serve it from nearby locations for lower latency. The guide closes with a simple test readers can run to check their own connection.
