IT320 OPERATING SYSTEM CONCEPTS Unit 3: Welcome to Linux September 2012 Kaplan University 1

Unit 3: Reading & Assignments  Textbook Reading  Chapter 2 (section on Linux)  1 Discussion Question  PowerPoint Presentation  Due Tuesday, September 11 Kaplan University 2

Unit 3: Discussion Questions  Linux distributions include many applications you would normally pay for on a Windows operating system.  Select two applications that are included with Linux and compare them to applications you paid for to use on Windows.  Share with the class your experience using the applications, is the functionality comparable, is it easy to use, would you recommend the application to others?  Compare the Linux and Windows operating systems. What differences and similarities have you found in Linux and Windows? Be as detailed as possible. Kaplan University 3

Unit 3: Linux PowerPoint  Create a presentation of at least 10 PowerPoint slides comparing three Linux distributions.  Your presentation should include, but not be limited to, the hardware requirements, features, applications and utilities included with your Linux distribution.  Select one Linux distribution you would recommend for home use. Be sure to defend your selection.  Also include a title slide and reference slide (not part of 10)  If you need any guidance using PowerPoint, you can refer to the Atomic Learning section in the course home unit. Kaplan University 4

Unit 3: Grading Rubric Kaplan University 5  Grading Rubric  10 points – Three different Linux distributions selected  10 points – Requirements & features of Linux Distribution 1  10 points – Requirements & features of Linux Distribution 2  10 points – Requirements & features of Linux Distribution 3  10 points – Recommended Linux defended

Overview of Linux 6 Kaplan University

What is Linux?  “Linux is a free Unix-type operating system originally created by Linus Torvalds with the assistance of developers around the world. Developed under the GNU General Public License, the source code for Linux is freely available to everyone.”  Source: Kaplan University 7

Who created Linux?  Started in 1991 as a variant of UNIX  Created by Linus Torvalds at University of Helsinki, Finland  Version 1.0 of the Linux Kernel released in 1994  Current version of Linux Kernel - Version Kaplan University 8

Linux - GPL  Torvalds released Linux under GPL  GNU general public license (GPL)  Very different from standard commercial software license  Author agrees to give away source code  Anyone is licensed to redistribute it in any form What is advantage of releasing under GPL? Kaplan University 9

Advantages of Linux?  Based on your readings for this class, name 2 advantages for using Linux. Kaplan University 10

Why Linux?  OS is free – you supply the hardware  Fully customizable  Powerful & exploit features of hardware  Linux Kernel is small & compact  Highly compatible with other OS  Well Supported  Open Source Kaplan University 11

Linux Kernel  Kernel = Operating System  Interacts with hardware system  Provides execution environment to applications  To learn more about Linux Kernel, try the O’Reilly book “Understanding the Linux Kernel”Linux Kernel  If you want to create your own, try the wiki site Kaplan University 12

Linux Kernel  Kernel is process manager not process  2 modes  User mode In user mode, applications can not access the kernel.  Kernel mode  Kernel switches between modes Kaplan University 13

Strengths & Weaknesses of Linux  What are some of the strengths to using Linux as your operating system?  What are weaknesses to using Linux? Kaplan University 14

Strengths of Linux  Stability  Security  Speed  Cost  Multiprocessing  Applications Kaplan University 15

Linux Distributions  Linux Kernel doesn’t provide all features of OS  Complete OS should include:  Hardware devices  Installation programs  Networking and system admin utilities  Personal productivity applications  Documentation  Linux Distributions  Version of Linux with OS Kernel and these components Kaplan University 16

Linux Distributions

Source: Kaplan University 18

Linux Distributions (“Flavors”)  Ubuntu  Fedora  openSUSE  Debian  Mandriva  FreeBSD  Linux Mint  PCLinuxOS  Slackware  Gentoo  CentOS  Plus hundreds more 19 Kaplan University Which distribution(s) of Linux have you worked with?

Hardware Requirements  Can run on very minimal hardware  Recommend that computer have minimum of:  1 GB of free disk space  64 MB of RAM  For Red Hat Enterprise Linux installations:  256 MB of RAM  300 MHZ CPU  800 MB of free disk space

Version Numbering  Version numbers assigned to:  Each release of Linux kernel  Each component of Linux distribution  Kernel version number components  Major version number  Minor version number  Patch-level number  Latest stable version for Linux Kernel  Version 3.5.3

Careers in Linux 22 Kaplan University

Linux Certification  Industry certification programs  Red Hat Certified Technician  Red Hat Certified Engineer  LPI Certification LPI Certification  Linux Certified Administrator (LCA) Certification  CompTia Linux+ Certification CompTia Linux+ Certification  Novell Certified Linux Engineer

Linux+  Complete 2 exams (60 questions each)  LX0-101 ($173) Exam covers system architecture; Linux Installation and package management; GNU and Unix commands; devices, Linux file systems, and file system hierarchy standard  LX0-102 ($173) Exam covers shells, scripting & data management; user interfaces & desktops; administrative tasks; essential system services; networking fundamentals; security Kaplan University 24

System Administrator  Linux is increasingly part of information technology infrastructure of large organizations  Knowledge of Linux can set you on path to a fulfilling and profitable career

The Complete Guide to Linux System Administration 26 Careers in Linux  System administrator  Network administrator  Software engineer  Trainer  Technical writer  Product marketing  Business consultant

Unit 3 Assignment 27 Kaplan University

Unit 3: Linux PowerPoint  Create a presentation of at least 10 PowerPoint slides comparing three Linux distributions.  Your presentation should include, but not be limited to, the hardware requirements, features, applications and utilities included with your Linux distribution.  Select one Linux distribution you would recommend for home use. Be sure to defend your selection.  Also include a title slide and reference slide (not part of 10)  If you need any guidance using PowerPoint, you can refer to the Atomic Learning section in the course home unit. Kaplan University 28

PowerPoint Assignment (slides)  Title  Overview / Preview of Presentation  What is Linux?  2-3 slides for Distribution 1  2-3 slides for Distribution 2  2-3 slides for Distribution 3  Recommended Distribution for home use & why  References Kaplan University 29

Example – CentOS Linux  CentOS Linux  Started in 2003  Based on Red Hat Enterprise Linux (RSEL)  Same as RSEL with centOS logo & branding  Stands for “Community ENTerprise OS”  Reliable server distribution  Updates released about every 2-3 years  Stable for enterprises, but not “latest & greatest” Kaplan University 30

Example – CentOS Linux  Version & Architecture  Current version is CentOS 6.3 for I386 and x86_64 architecture  CentOS currently supports the following architecture X86 – based on Intel 8086 CPU X86 X86_64 – 64 bit processor Ia64 – Intel Itanium architecture (primarily for servers)Intel Itanium architecture Source: Kaplan University 31

Example – CentOS Linux  Features  Stable & Secure  Includes OpenOffice 2.0  No DVD software interface  Utilities  Updated by YUM (Yellowdog Updated Modifier)  GNOME & KDE GUI Interfaces  RPM (RedHat Package Manager) Kaplan University 32 Source: post html
