LINUX

LINUX (LIH-nuks)

Unix Originally developed at AT&T as a

multitasking system for minicomputers and mainframes in the 1970’s.

Linux Developed primarily be Linus Torval. Inspired by Minix. Kernel uses no code from AT&T or any other

proprietary source. Developed by a group of volunteers,

primarily in the Internet, who exchange code, report bugs and fix problems.

What is so special about Linux.

Linux is said to be:Reliable.Simple.Free!Runs on a variety of platforms.considered the most important free

software achievement.Able to turn any 80386 or better PC

into a workstation.

LINUX

Features: Complete multitasking, multiuser OS. Compatible with Unix standards. Supports virtual consoles. Supports various file systems for storing data. Provides complete implementation of TCP/IP

networking software. Include device drivers for many Ethernet cards.

LINUX

Features (cont.) Kernel

is developed to use protected-mode features of Intel 80386 and better processors.

supports demand-paged and loaded executables. supports copy-on-write pages.

Linux can coexist with other OS on the same machine.

GNU/Linux K Desktop Environment

KDE is a powerful GUI desktop environment for Unix workstations.

Provides ease of use, contemporary functionality, and the technological superiority of the Linux OS.

KDE is an internet project that is "Open" in every sense.

All KDE sources are open to everyone and may be distributed by anyone subject to the well know GNU licenses.

KDE is a mature desktop suite.Visit WWW.KDE.ORG for further information.

The GNU Project

Launched in 1984 to develop a completely Free Unix-like operating system: The GNU System. Many flavors of the GNU system are currently in use, i.e. Caldera, Redhat, Corel, etc.

These GNU Systems use the Linux Kernel, these systems are incorrectly called "Linux", they should be called GNU/Linux systems.

GNU is "Copylefted". Copyleft uses copyright law in reverse. It allows software to be used, modified, and distribute modified versions. Modified versions may not add restrictions of their own.

Visit www.gnu.org for more information.

Current KDE DistributionIncludes the following

packages:

KDE-Libs: Various Run-time librariesKDE-Base: The base componentsKDE Graphics: e.g. Kpaint, Kfax, KghostviewKDE Utilities: Kedit, KCalc, KnotesKDE-Multimedia: KMidi, Kmodplayer, Kmixer,

KSCDKDE-Games: Kasteroids, Kpat, KtetrisKDE-Admin: Various rools to aid system

administration

Current KDE DistributionIncludes the following

packages:

KDE-Network: Kppp, Krn, KmailMost current distributions of Linux

Use a modified version of KDE. Corel calls its version Enhanced KDE.

The Value of Linux Application

Linux is a complete multitasking , multi-user operating system. It supports various file system and applications.

Linux is much more compact and runs similar applications much faster than Windows.

Lower Cost

Most of Linux software and applications are inexpensive, which you can purchase in diskette or CD-ROM format. E.g. CorelDraw, WordPerfect 8, Domino R5, games, etc….

Linux is free and easily downloaded from the internet, or can be purchased at a much lower cost than Windows software.

Ease of Operation

Corel Linux has an Update wizard which can install more recent versions automatically.

Use Corel update to remove applications that you no longer want to use.

Reinstall deleted applications at any time.

Init Program’s Main Roles

It creates processes, which has the effect of bringing the system up to the default run level.

It controls transitions between run states by re-reading the inittab file.

Inittab File Defines

The system’s default run levelWhat actions to be taken when the

system enters a new run levelWhat processes to start, monitor,

and restart if they die

Run Control Scripts

The scripts for starting and stopping system services are located in the rcR.d directories, where R is the run-level.

Files that start with S are used to start processes.

Files that start with K are used to kill processes.

Init.d DirectoryThe start and kill files in the rc#.d

directories are hard linked to scripts in the init.d directory. This is done to facilitate booting.

An important advantage of having the actual run control files in the init.d directory is that you can start and stop individual processes from a single location without changing run levels.

Well, Linux is a multitasking OS, so it's a perfect OS for multimedia.
