Linux Networking - Basics and Beyond: Unit 2

In this module you’ll explore the core networking services that application-level protocols depend on. Without these foundational networking services, data communications wouldn’t be possible. You’ll learn about the three most commonly used networking services in Linux, including the traditional service used primarily by Debian servers, the foundational service for Ubuntu Servers, and the widely used Network Manager Service found on systems like Red Hat, Fedora, CentOS, and many Linux desktop environments.
