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.

Introduction
5
Introduction to Linux

• line-ucks or lih-nicks
• Created primarily by Linus Torvalds in 1991
• First commercial release was in March, 1992

6
Introduction to Linux (cont)

• Linux is an operating system very much like Unix
• Multi-tasking, multi-user
• Developed by several users to replace Minix
• Freely distributed, becoming more popular every
  day

7
Why Linux is so popular

• Free
• Reliable no crashes
• Simple to use and install
• Developer friendly
• Runs on several different platforms
• Allows older 386 and 486 processors to run much
  faster
• Can coexist with other OSs

8
About Linux
9
The Linux kernel

• Originally developed for the Intel 80386 CPUs
  protected mode
• Completely compatible with Unix standards
• Allows shared executables
• Supports demand paging
• Uses a unified memory
• Supports swap space

10
The Linux kernel (cont)

• Uses dynamically shared libraries extensively
• Allows full library linking
• Supports a number of file systems
• DOS
• OS/2
• Ideally suited for application development

11
The Linux kernel (cont)

• Includes several programming language compilers
• C
• C
• Fortran
• Pascal
• LISP
• Ada
• BASIC

12
Linux and DOS

• Linux provides a DOS emulator, allowing DOS
  applications to be executed
• WINE (Windows emulator)
• WABI
• Files can be transferred between the DOS and
  Linux file systems
• Linux can access DOS partitions on a
• hard disk directly

13
Linux and TCP/IP

• Provides complete TCP/IP networking software to
• Create a local area network
• Attach to an existing Ethernet LAN
• Connect to the internet

14
Linux environments

• Text-based
• Graphical user interface (GUI) called X or X
  Window
• Very popular, especially with users new to Linux
• KDE
• GNOME

15
Importance of Linuxs XFree86

• XFree86 is Linuxs GUI
• Easy to use
• Very similar to Windows environment
• Windows users can make easy transition
• Can install and run Windows applications
