How does FreeBSD differ from Linux, and what is it?
A wide range of operating systems have developed over time, some of which served as the foundation for more well-known ones. However, there are other, crucial options besides macOS, Linux, or Windows that many people are unaware of.
One example of this is FreeBSD, which has proven to be a solid and reliable choice for users. It is open source and has its roots in Unix, and unlike Linux, which was created from scratch as an alternative to Unix, FreeBSD is directly descended from that system.
FreeBSD began as an enhancement to Unix in the 1970s and 1980s, under the name Berkeley Software Distribution (BSD). Over time, it evolved into a standalone operating system used on both servers and some personal computers.
How FreeBSD Works
FreeBSD shares many similarities with other Unix-like systems, such as Linux. It uses a command-line interface as well as providing support for graphical desktop environments such as GNOME or KDE. Its modular architecture allows for great flexibility and customization. It also offers support with server hardware, although interoperability with desktop computers, especially laptops, can be challenging.
For example, getting components like Wi-Fi or Bluetooth to work properly sometimes requires additional tools, or in some cases may be impossible. However, once configured, FreeBSD offers great stability.
How is FreeBSD different from Linux?
Architecture: FreeBSD is directly descended from Unix, while Linux is a modern reinterpretation built from scratch. This makes FreeBSD offer a more "pure" Unix experience.
Licensing: FreeBSD uses the BSD license, which is more permissive than the GPL license used by Linux. This means that companies can take FreeBSD code, modify it, and use it in their own projects without having to release those modifications.
Compatibility: It is compatible with a wide range of devices but has limitations on newer devices, such as laptops with specific hardware that work with Bluetooth or Wi-Fi. On the other hand, Linux offers broader support for modern computers.
Kernel: FreeBSD has its own kernel, while Linux uses a kernel developed by a global community. This translates into differences in performance, security, and customization for each system.
- Ecosystem: Although FreeBSD has a comprehensive catalog of native software, some popular Linux applications require additional configurations to run on FreeBSD, such as installing compatibility layers.
FreeBSD is an excellent choice if you are looking for a stable operating system that focuses on security. Its architecture and reliability make it the perfect choice for servers and networks, where performance and continuity are essential.
