Q

Explain Distributions

A

Different distributions are used for different reasons.
Different Linux distributions contain different preinstalled programs, user interfaces, and much more.
A lot of this is based on what the Linux user needs, but some distros are also chosen based on preference.

The advantage of using Linux as an OS is that you can customize it.
Distributions include the Linux kernel, utilities, a package management system, and an installer.
Linux is open source, and anyone can contribute to adding to the source code.
That is how new distributions are created.

All distros are derived from another distro, but there are a few that are considered parent distributions.

28
Q

Describe AlmaLinux

A

AlmaLinux is a community-driven Linux distribution that was created as a stable replacement for CentOS.

CentOS was an open-source distribution that is closely related to Red Hat, and its final stable release, CentOS 8, was in December 2021.
CentOS used source code published by Red Hat to provide a similar platform.

AlmaLinux is designed to be a drop-in replacement for CentOS 8.
This ensures that applications and configurations that worked on CentOS will continue to function on AlmaLinux.

29
Q
