is NOT an OS (Operating System). Linux
is the actual kernel from which
the platformed distribution runs and obtains directions. The Linux
kernel is an open
source system which falls
under the GNU General Public license. In essence, Linux
is a compressed, open
source platform of UNIX. The actual OS's (distributions or flavors) are gentoo, red hat, unbuntu, slackware (Although very
similar to straight UNIX), mandrake, arch, debian, mandriva, etc.
kernel was designed and constructed by Linus Torvalds to provide a free, open
source kernel for all computer lovers.
