How secure is Ubuntu compared to Windows?

Ubuntu is generally more secure due to its Unix architecture, smaller attack surface, rapid security updates, open source code review, and built-in security features like AppArmor. The Linux permission system also prevents many common malware attacks.

What is the difference between Ubuntu Desktop and Ubuntu Server?

Ubuntu Desktop includes a graphical interface (GNOME), multimedia applications, and desktop tools. Ubuntu Server has no GUI by default, is optimized for server workloads, uses less RAM, and includes server-specific tools for web hosting, databases, and containers.

Can I dual-boot Ubuntu with Windows?

Yes, Ubuntu’s installer supports dual-booting. It can automatically resize Windows partitions and install alongside Windows. The GRUB bootloader lets you choose which OS to boot at startup.
