In this tutorial, we will learn how to install the latest kernel version on multiple Linux distributions.
What Is A Kernel
First, let’s define what a kernel is defined as. The Linux kernel is basically the brain of your hardware. Its main purpose is to facilitate communications between your hardware and software. As an example, if an application needs to make a change (say switching the screen resolution of your monitor), the software submits a request to the kernel, and the kernel uses the available video driver options to modify the resolution.

When did DNF become the default package manager for Fedora?
DNF has been the default package manager for since the 22nd version of Fedora, Fedora 22. Dandified Yum was introduced in Fedora 18.
Why was yum replaced with DNF?
Yum has long been considered a poor performer. It was notorious for high memory usage, and the slowness when resolving dependencies. DNF now uses libsolv, an external dependency resolver, and hawkey for resolving dependencies, while yum used its own, internal, dependency resolver.
