Summary  
This chapter explains how to use virtualization to create and configure a virtual machine, allocate its resources, install an operating system, and set up user credentials.

General domain of usage  
Software development and testing environments

VirtualBox is like a **box** where you can **create and run virtual computers** on your **regular computer**. It allows you to have **multiple operating systems** (like **Windows, Linux**, etc.) on one computer and **switch between them**. It also lets you **share files** between these **virtual computers** and **customize them** to suit your needs.

If you are a Windows or macOS user on an Intel processor, then **Virtual Box** is a good choice for creating a virtual machine, <a href="https://www.virtualbox.org/wiki/Download_Old_Builds_7_0" target="_blank"><svg width="1em" height="1em" viewBox="0 0 30 32" fill="none" xmlns="http://www.w3.org/2000/svg"><path fill="none" stroke="#098f67" style="stroke: var(--color1, #098f67)" stroke-linejoin="miter" stroke-linecap="round" stroke-miterlimit="4" stroke-width="2.4156" d="M17.289 17.305v0c-1.754 1.754-4.597 1.754-6.351 0l-7.76-7.759c-1.755-1.755-1.755-4.601 0-6.356v0c1.753-1.753 4.595-1.756 6.351-0.005l6.208 6.187"></path><path fill="none" stroke="#098f67" style="stroke: var(--color1, #098f67)" stroke-linejoin="miter" stroke-linecap="round" stroke-miterlimit="4" stroke-width="2.4156" d="M12.504 13.97v0c1.754-1.754 4.597-1.754 6.351 0l7.762 7.762c1.754 1.754 1.754 4.597 0 6.351v0c-1.754 1.754-4.597 1.754-6.351 0l-5.953-5.953"></path></svg>download</a> the virtual box from the official website. VirtualBox is a free program.

If you are a macOS user on apple processors (M1/M2/M3), then the **UTM** program will suit you. If you are such a user, you can skip this chapter and learn to work with <b>UTM</b>.


Note

When installing VirtualBox, leave all options at their default settings.

Learning Linux is valuable for many IT professions. For system administrators, DevOps engineers, and backend developers, it enables efficient server management, automation of software development and deployment, and the development and management of server-side applications. For network administrators, cybersecurity professionals, and data analysts, Linux knowledge helps effectively manage networks, ensure security, and analyze data.

Learn what Linux is, explore its key advantages, and understand why it’s a preferred choice among developers. Choose a Linux distribution to work with throughout the course.

Set up a virtual environment and install Linux on your computer to safely practice commands without affecting your main system.

Gain essential Linux skills such as using the terminal, navigating files, installing programs, and keeping the system updated.

Discover how to manage users and groups, configure file permissions, and control access rights within the Linux environment.
