Ubuntu has several editions that can run on different types of systems, including core, server, and desktop. Each edition is available for personal computers, servers, supercomputers, cloud computing, and more.

Ubuntu is an operating system that appeals to users as it is a free, open source solution that is secure and easy to use. It is also user-friendly, customizable, and offers improved security within the OS.

2) Differences between Ubuntu Server and Desktop

Ubuntu Server Edition and Ubuntu Desktop Edition use the same apt repositories, so you can easily install server applications on the Desktop Edition just as you would on the Server Edition.

One major difference is that the graphical environment used in Desktop Edition is not installed for the server. This includes the graphics server itself, graphics utilities and applications, and various user support services required by desktop users.

3) Ubuntu installation system requirements

Ubuntu Server Edition provides a common, minimalist foundation for a variety of server applications such as file/print services, web hosting, email hosting, and more. Ubuntu Server Edition versions support four 64-bit architectures.

amd64 (Intel/AMD 64-bit)
arm64 (64-bit ARM)
ppc64el (POWER8 and POWER9)
s390x (IBM Z and LinuxONE)
CPU: 1 GHz or higher
RAM: 1GB or more
Disk: 2.5 GB minimum

4) Preparing to install Ubuntu

Before installing Ubuntu Server Edition, make sure all data on your system is backed up. If this is not your first time installing an operating system on your computer, you may need to repartition your disk to make room for Ubuntu.

Whenever you partition a disk, you should be prepared to lose all the contents of the disk if you make a mistake or encounter problems while partitioning. The programs used for installation are very reliable and most have been around for many years, but they also perform destructive actions.
