What is Ubuntu?

Ubuntu is a free, open-source operating system based on Linux, designed to make Linux simpler and more user-friendly for everyday computer users. You can perform daily tasks like browsing, writing documents, watching videos, and running software. It cn be used on desktops, laptops, servers, and even Internet of Things (IoT) devices.

Even more, Ubuntu offers everything most users need, like a clean interface, built-in apps, strong security, and lots of free software. It makes computing easy, secure, and efficient for everyone, from beginners to professionals. It offers a smooth, user-friendly experience whether you’re using it for personal, educational, or professional purposes.

Key Features of Ubuntu

Now that you know what is Ubuntu, below are its key features:

1) Free and Open Source

Ubuntu is completely free to download and use. Much of Ubuntu and the software it distributes is open source, allowing users and developers to inspect, modify and contribute to the underlying code according to the applicable licences.

2) User-friendly Interface

Ubuntu offers a clean, intuitive interface that’s easy to navigate, even for those new to Linux. Its graphical desktop environment allows users to perform many everyday tasks without relying heavily on command-line tools.

3) Software Selection

Ubuntu provides essential applications by default and offers additional software through the App Center. The exact pre-installed applications can vary depending on the Ubuntu release and installation option selected.

4) Regular System Updates

Canonical releases system updates for Ubuntu every six months, adding new features and security improvements. The Long-term Support (LTS) versions, released every two years, receive five years of standard security maintenance, with extended coverage available through Ubuntu Pro.

5) Ubuntu Editions, Products and Flavours

Ubuntu comes in different versions for different needs:

1) Ubuntu Desktop for personal computers

2) Ubuntu Server for websites and applications

3) Ubuntu Core for IoT devices

4) Ubuntu Cloud for virtual environments

5) Lightweight versions like Xubuntu and Lubuntu for older machines

6) Broad Hardware Support

Ubuntu supports a wide range of hardware, and many common devices work automatically. However, compatibility can vary, particularly with newer or specialised hardware.

7) Strong Security Measures

Ubuntu is known for being safe and secure. It has built-in protection tools, automatic updates, and uses a permission system where you must approve major actions. You don’t normally run as the “root” user, which adds another layer of safety.

8) Highly Customisable

Ubuntu offers extensive customisation options, including themes, icons, layouts and alternative desktop environments such as KDE Plasma or Xfce.

9) Active Community Support

One of Ubuntu’s greatest strengths is its active and supportive global community. Whether you face a technical issue or want to learn something new, you can easily find help through different sources and official support channels.

Common Use Cases of Ubuntu

Ubuntu can be used for many things, from simple home tasks to big business systems. Here are some of its common use cases:

1) Personal Computing

Many people use Ubuntu every day for basic tasks like browsing the web, writing documents, watching videos, and using social media. It is lightweight and efficient. So, it is perfect for home or office computers.

2) Server Hosting

Ubuntu Server is widely used for web hosting, application servers, databases, cloud infrastructure and other server workloads. It is reliable, fast, and easy to maintain. Companies and data centres use it to host everything from small blogs to large data centres.

3) Web Development

Ubuntu supports popular programming languages such as Python, PHP and JavaScript, as well as web-server and database software such as Apache and MySQL.

4) Contributing to Open Source

Developers can contribute code, report or fix bugs, package software and participate in Ubuntu community projects. Advanced users can also create customised Ubuntu-based distributions or images.

5) Educational Purposes

Schools and universities use Ubuntu to teach programming, computer science concepts and system management. It is free, secure, and easy for students to experiment with without needing expensive licences.

6) Internet of Things (IoT)

Ubuntu Core is an immutable version of Ubuntu designed for embedded and IoT systems. It uses sandboxed applications and transactional updates to support secure and reliable device deployments.

7) Linux Gaming

Gaming on Ubuntu has grown significantly in recent years. With support from platforms like Steam, and tools such as Proton and Wine, users can enjoy both Linux-compatible and many Windows-based games. Performance and compatibility have improved greatly, making Ubuntu a solid choice for casual and dedicated gamers alike.

Bonus Tip: Before switching operating systems, list your essential applications and back up important files so compatibility gaps do not become unexpected problems.

How to Install Ubuntu on Your Device?

Now that you know the features and use cases of Ubuntu, let’s check how to install it on your device:

1) Downloading the Ubuntu ISO

You can download Ubuntu directly from the official Ubuntu website. You can choose the version you want and download the file. It contains everything needed to install Ubuntu. Save it on your computer.

2) Choose a Bootable USB Creation Tool

Ubuntu's official installation guide recommends different tools depending on your current operating system. Windows users can use Rufus, macOS users can use balenaEtcher, and Ubuntu users can use the Disks application.

Let's consider that you download and install a free balenaEtcher. It helps you put the Ubuntu installation file (ISO) onto a USB stick, so you can use it to install Ubuntu.

3) Creating a Bootable USB Drive

Once balenaEtcher is ready, insert a USB drive (8 GB or above) into your computer. Make sure it doesn’t contain important data because it will be erased. Now, open balenaEtcher and follow these steps:

1) Click Select Image and choose the Ubuntu ISO file you downloaded

2) Click Select Target and pick your USB drive

3) Click Flash to begin creating your installation drive

When the process finishes, safely remove your USB stick. It is now ready to install Ubuntu.

4) Booting from Installation Media

Restart your computer and open the boot menu (press F12, ESC, or another key depending on your system). Select your USB stick as the boot device. Ubuntu will start in “live mode,” allowing you to try Ubuntu before installing or go straight to Install Ubuntu.

5) Completing the Ubuntu Installation

Click Install Ubuntu and follow the on-screen instructions. Choose your language, accessibility settings, keyboard layout, and network preferences. For the installation method, select either interactive installation or automated installation.

Most users can choose interactive installation, followed by either Default selection for essential applications or Extended selection for additional office tools and utilities. Then configure the disk setup, create your account, select your time zone, and complete the installation.
