Before the advent of modern operating systems, early computers were controlled through simple command-line interfaces. As computing evolved, the need for more user-friendly systems led to the creation of operating systems (OS), revolutionizing how users interact with technology. Today, the debate over which OS is the best remains.

However, many other operating systems have gained popularity, especially among tech enthusiasts. Linux is widely favored by developers and programmers. BSD (including FreeBSD, OpenBSD, and NetBSD) is highly regarded by security-focused professionals and iOS, on the other hand, is the preferred choice for iPhone lovers.

Each operating system offers varying levels of security, performance, and features. The right choice depends on your specific needs and preferences. To help you make an informed decision, here’s a list of the 10 safest operating systems.
