Linux Distribution Versions
The way Linux is developed and distributed, has caused the operating system to
fragment into multiple commercial flavors. Today there are close to 200 Linux
distribution versions. Some of the most popular distribution versions include
Caldera OpenLinux eServer, Red Hat, SuSE, TurboLinux Server, LinuxMandrake, Connectiva, and Red Flag. These versions are available from
commercial vendors who make money by selling their implementation, as well as
installation, maintenance, and other services. Linux is also distributed by the nonprofit Debian organization, whfch is developing a free operating system and
The existence of multiple Linux distribution versions frees users from being
locked into one vendor. It also creates healthy competition, which furthers
innovation. Additionally, the different versions of Linux have always catered to
slightly different markets. For example, the SuSE version is for users in banking
and telecommunications industries, and the Connectiva version has been focused
towards South American market.
The main differences among various distribution versions include the set of tools,
library version, number and quality of applications, documentation, support, and
Linux Distribution and Installation
Linux has traditionally been organized as a series of floppy disks - the A series
containing the basic system, the D series containing the compilers and program
development tools, the N series containing the modules for networking features,
and so on. The total series comes in about 50 floppy disks. However, not every
user needs the entire set of floppy disks. For example, you do not need the N series
floppy disks, if you do not want networking features.
Linux can be installed on a computer system either as the only operating system or
along with other popular operating systems such as MS-DOS or Microsoft
Windows. When multiple operating systems are installed on the same machine, you can boot the machine by choosing the appropriate operating system at the time
