10. Virtualization and containerization are two popular
technologies in Red Hat Linux. Virtualization allows
multiple operating systems to run on a single
physical machine, enabling better resource
utilization. Containerization, on the other hand,
enables the creation and deployment of lightweight
and isolated application containers, making it
easier to manage and scale applications. Both
technologies contribute to improved efficiency,
flexibility, and portability in the Linux environment.

11. System backup and recovery in Red Hat Linux involves
creating copies of critical data and system
configurations to ensure their availability in case of
data loss or system failure. This can be done using
tools like rsync, tar, or Amanda. To recover the
system, the backups are restored, and any necessary
configurations are performed to bring the system back
to its previous state.
