Introduction




LINUX is a free, from scratch operating system
based heavily on the POSIX and UNIX APIs.
LINUX itself is not
UNIX,
although many
people call it
that and you would
be very hard
pushed to tell the
difference.
This is because the UNIX trademark has a cost
and is specific to systems that meet a complex set
of X/Open standards.
Kind of OS: open source UNIX



UNIX is a trademark that was transferred by
NOVELL UNIXWARE.
Microsoft's Windows NT Server Vs. UNIX — is,
strangely enough, being upstaged by a Johnnycome-lately called LINUX.
UNIX-clone LINUX’S emerging popularity gives
small businesses another attractive alternative
when plotting their network operating system
(NOS) strategies, it also adds confusion to an
already muddled issue

Kernel: LINUX



The LINUX kernel was originally written by
LINUS Torvalds(hence the name “LINUX”
The LUINUX kernel maintained by a team of
developers.
The kernel itself is released under the GPL(GNU
Public License).
RED HAT
Red Hat routinely tests systems and
peripherals to determine whether they
operate correctly with Red Hat LINUX.
 The Red Hat Service Organization keeps
these Hardware Compatibility lists up to
date for all supported versions of Red Hat
LINUX, which include i386, SPARC, and
Alpha architectures 6.2,6.1,6.0,5.2.

Red Hat


Red Hat believes that the hardware on these lists
operates correctly with Red Hat Linux
but because there are an infinite variety of
computer system configurations and the
manufacturing specifications and components of
hardware change, Red Hat cannot guarantee
compatibility with any hardware
RED HATE READY



The Red Hat Ready Program is a useful tool for
Independent Hardware Vendors.
A vendor may submit its hardware (including
peripherals and systems) to undergo a rigorous
certification process performed by highly qualified
in-house Red Hat Technicians.
Certification earns the vendor the right to display
the Red Hat Ready logo.
RED HAT READY




The advantages of having your hardware certified
under the Red Hat Ready Program are:
Verification that your hardware is fully compatible
with the current version of Red Hat LINUX.
Use of the Red Hat Ready logo on approved
products.
Your customers will recognize the Red Hat Ready
logo and know that your hardware can be trusted
to perform when they run Red Hat LINUX.

Red hat linux 6.1
Red hat linux6.1 features:
 includes a new graphical installation
process in addition to the more traditional
character-cell installation mode.
 Some new features are tools or applications
that you can use, others are new versions of
the kernel or desktop environments.

System Configuration With
Linuxconf



Linuxconf is a utility that allows you to configure
and control various aspects of your system, and is
capable of handling a wide range of programs and
tasks.
More information on Linuxconf, including its
status, most recent release, and more can be found
at the Linuxconf Project homepage:

Three menu interface
linuxconf comes complete with a tree menu interface
