This is the third part in our seven-part series on the BSD series of operating systems.FreeBSD is the most widely-used BSD operating system. It runs on amd64, 64-bit ARM (aarch64), i386, 32-bit ARM (armv6, armv7), RISC-V, and PowerPC. In earlier times, I thought of the three BSDs (DragonFly wasn’t around yet) as “NetBSD = runs on anything, OpenBSD = high security, FreeBSD = awesome on amd64”.
