Taking the FreeBSD Plunge
FreeBSD is an enterprise-grade operating system that leaves little to be desired. Most people have tried Linux by now, but a surprisingly large number of people have not yet taken FreeBSD for a spin. Now may well be the optimal time to take the plunge, as FreeBSD 6.0 provides the same rock-solid stability for which FreeBSD is known, and also implements some outstanding new features.
The main difference between Linux and FreeBSD is that FreeBSD is an entire operating system. Linux has many distributions, all of which use the Linux kernel and each of which has its own special utilities and configuration tools to learn. FreeBSD comes with a kernel and all of the basic user programs necessary to run a production server.
