The document is a presentation about the Linux operating system and the Red Hat distribution. It provides an overview of Linux, describing it as a free operating system similar to Unix. It details the installation process for Red Hat 6.2, including hardware requirements and step-by-step instructions. It also introduces the KDE desktop environment and demonstrates how to add a printer after installation.
Linux is the best-known and most-used open source operating system. As an operating system, Linux is software that sits underneath all of the other software on a computer, receiving requests from those programs and relaying these requests to the computer's hardware.

2. Correcting installation problems
3. Setting up user accounts
4. Connecting to the network
5. Configuring utilities
In the presentation I have tried to cover the Evolution of Linux as an Operating System. The most of the content used is freely available on Internet , I have just tried to streamline it and summarize it as cleanly as possible from my point of view. Any improvements, suggestions, comments are most welcom.
It is a Unix like operating system.
It can run on 32 bit and 64 bit hardware.
Linux OS, is a freely distributable, cross-platform
Supports multiple processors.
True multi-tasking, multi-user OS.
Following are some of the important features of Linux Operating System.
Portable - Portability means softwares can works on different types of hardwares in same way.Linux kernel and application programs supports their installation on any kind of hardware platform.
Open Source - Linux source code is freely available and it is community based development project. Multiple teams works in collaboration to enhance the capability of Linux operating system and it is continuously evolving.
Multi-User - Linux is a multiuser system means multiple users can access system resources like memory/ ram/ application programs at same time.
Multiprogramming - Linux is a multiprogramming system means multiple applications can run at same time.
Hierarchical File System - Linux provides a standard file structure in which system files/ user files are arranged.
Shell - Linux provides a special interpreter program which can be used to execute commands of the operating system. It can be used to do various types of operations, call application programs etc.
Security - Linux provides user security using authentication features like password protection/ controlled access to specific files/ encryption of data.
This ppt discusses the history of both the operating systems & compares both of them in terms of Kernel, memory management, GUI and application support.
Virtualization with KVM (Kernel-based Virtual Machine)Novell
As a technical preview, SUSE Linux Enterprise Server 11 contains KVM, which is the next-generation virtualization software delivered with the Linux kernel. In this technical session we will demonstrate how to set up SUSE Linux Enterprise Server 11 for KVM, install some virtual machines and deal with different storage and networking setups.
To demonstrate live migration we will also show a distributed replicated block device (DRBD) setup and a setup based on iSCSI and OCFS2, which are included in SUSE Linux Enterprise Server 11 and SUSE Linux Enterprise 11 High Availability Extension.

File system is an approach on how the data can be
organized in order to have a meaningful read or write in a
system. File systems provides a very easy way of identifying data like where it begins and ends. The group of such data can be called as “Files”. The method used to manage these groups of data can be called as “File systems”
Regarding Clouds, Mainframes, and Desktops … and LinuxRobert Sutor
In this talk, I'll focus on three areas of great opportunity as well as challenge for Linux: the accelerating market for cloud computing, Linux as a significant operating system for mainframes, and the hope for Linux on the desktop.
These are the slides I presented at Singapore Linux Meetup Group. We look at KDE4 which is still Alpha quality code, as well as some of nice features of KDE (irrespective of versions)
Red Hat Enterprise Linux (RHEL) is a Linux-based operating system from Red Hat designed for businesses. RHEL can work on desktops, on servers, in hyper visors or in the cloud. Red Hat and its community-supported counterpart, Fedora, are among the most widely used Linux distributions in the world.

This is a presentation by Dada Robert in a Your Skill Boost masterclass organised by the Excellence Foundation for South Sudan (EFSS) on Saturday, the 25th and Sunday, the 26th of May 2024.
He discussed the concept of quality improvement, emphasizing its applicability to various aspects of life, including personal, project, and program improvements. He defined quality as doing the right thing at the right time in the right way to achieve the best possible results and discussed the concept of the "gap" between what we know and what we do, and how this gap represents the areas we need to improve. He explained the scientific approach to quality improvement, which involves systematic performance analysis, testing and learning, and implementing change ideas. He also highlighted the importance of client focus and a team approach to quality improvement.
How to Create Map Views in the Odoo 17 ERPCeline George
The map views are useful for providing a geographical representation of data. They allow users to visualize and analyze the data in a more intuitive manner.
Operation “Blue Star” is the only event in the history of Independent India where the state went into war with its own people. Even after about 40 years it is not clear if it was culmination of states anger over people of the region, a political game of power or start of dictatorial chapter in the democratic setup.
The people of Punjab felt alienated from main stream due to denial of their just demands during a long democratic struggle since independence. As it happen all over the word, it led to militant struggle with great loss of lives of military, police and civilian personnel. Killing of Indira Gandhi and massacre of innocent Sikhs in Delhi and other India cities was also associated with this movement.
We all have good and bad thoughts from time to time and situation to situation. We are bombarded daily with spiraling thoughts(both negative and positive) creating all-consuming feel , making us difficult to manage with associated suffering. Good thoughts are like our Mob Signal (Positive thought) amidst noise(negative thought) in the atmosphere. Negative thoughts like noise outweigh positive thoughts. These thoughts often create unwanted confusion, trouble, stress and frustration in our mind as well as chaos in our physical world. Negative thoughts are also known as “distorted thinking”.
2. Summary
• Research for the Power Point presentation revealed that Linux is a
free operating system that has been compared to and even rated
better and faster than the Windows operating system. Additionally,
Linux is very popular with software developers because of the many
programming language compilers Linux is equipped with. One of
the preferred features of Linux is the fact that one can run different
applications at the same time on different desktops.
• Our original intentions for this project were to include an actual
demonstration of the RedHat installation. Unfortunately, after many
hours were invested in the attempt to install Linux, we were
unsuccessful. We attribute the failed installation to incompatible
hardware, and have not given up on the belief that Linux is easy to
install. We plan on successfully installing Linux in the near
future and will be happy to share our results with anyone
interested.
