About
FreeBSD is an operating system that can run on most modern machines. The operating system is Unix-like,
and it is accordingly programmed mostly in C. The default user interface is simply the Unix shell by default.
As the name suggests, FreeBSD is entirely free and open. What may not be expected is that BSD actually
stands for “Berkeley Software Distribution”, which points to its origins in the Berkeley Software Distribution developed at the University of California, Berkeley; today it is maintained by the FreeBSD Project and its volunteers.
You can download FreeBSD easily, but it is also available in the form of a CD or flash drive.
FreeBSD is used not so much as a daily tool like some Linux distributions or Windows and macOS.
Instead, FreeBSD holds very prominent use in servers, mostly high-end ones, take for example Email servers,
web servers in general, or any sort of server that requires higher reliability and functionality than
what you might get with a machine running Windows or something of the sort.
A very important feature that adds to the server functionality is that with proper hardware and maintenance,
FreeBSD can run for years without having to reboot, which is crucial for maintaining a stable server
in the case of businesses and services.
FreeBSD has remarkable properties such as security that is arguably top of the line when working with data.
It has access control lists, automatic security auditing, among many other characteristics that are
constantly being developed by some of the smartest scholarly minds for the good of the general public,
as they do so free of charge. One of the key features of FreeBSD are jails, which are akin to virtual machines,
which can run processes inside but cannot access other components of the machine and the system in general.
This is useful when dealing with highly protected data and is a very welcome addition to the operating system.
As another key feature, FreeBSD is a multi-user system that can run simultaneous processes,
and also handles them quite elegantly. This feature is very useful when having multiple people working on
the same server and machine.
