The Fabric of Connection: An Introduction to Computer Networking
Networking is the practice of connecting computers and devices to enable them to communicate, share resources, and exchange information. It is the foundation of the modern digital world, powering everything from the internet and local area networks (LANs) to vast corporate infrastructures. The field of networking involves a wide range of technologies, protocols, and hardware, including routers, switches, and cables, all working together to ensure data is transmitted reliably and securely. Understanding the principles of networking is essential for anyone who wants to manage a home network, work in IT, or simply understand how the connected world operates.
