Understand what Linux is and what Linux distributions are in a brief and succinct way.

# What is Linux?

Linux is a Kernel, created in 1991 by Linus Torvalds.

Kernel is the operating system component responsible for “talking” to the hardware, it’s the bridge that connects the “physical” part of the computer with the “logical” part.

# Linux Distributions

The Kernel is just one part of a Linux distribution, responsible for hardware communication with the operating system’s application layer. On the other hand, a Linux distribution is the use of the Linux Kernel with other tools, in order to create a usable operating system, with interface, applications, administrative tools and various other functionalities.

Some examples of Linux distributions:

• Debian
• RedHat
• openSUSE
• Slackware

# Conclusion

Linux is the kernel, the core of the system. It handles communication between hardware (CPU, Memory and Devices) and the logical part of the system (applications).

A Linux Distribution is a collection of software that uses the Linux Kernel, bringing to life a usable operating system based on the Linux Kernel.

It’s worth noting that this post doesn’t aim to exhaust the understanding of what Linux and Linux Distributions are, it’s just an overview of a very broad topic discussed in the community.
