Technical requirements

You can continue the practice using the virtual machine (VM) created at the beginning of this book in Chapter 1, Installing RHEL8. Any additional packages required for this chapter will be indicated alongside the text. You will also need partitioning disks (MBR and GPT disks).

Let's start with a definition

A partition is a logical division of a storage device and it's used to logically separate the available storage into smaller pieces.

Now, let's move on to learning a bit about the origins of storage to better understand it.
