Summary  
This chapter covers the fundamentals of networking—how to connect devices via LANs and WANs to enable data and resource sharing across interconnected systems.  

General domain of usage  
Computer networking


Networking refers to the process of connecting multiple devices, such as computers, smartphones, and servers, to share data and resources. This process is essential in modern communication and supports everything from emails to smart home systems. In the past, devices operated in isolation, but today, networks create an interconnected web that enables seamless data sharing across the globe.
