LINUX RED HAT

Presented by

summary
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.

  • Developed by several users to replace Minix
  • Freely distributed, becoming more popular every day
why linux is so popular
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 OS’s
the linux kernel
The Linux kernel
  • Originally developed for the Intel 80386 CPU’s protected mode
  • Completely compatible with Unix standards
  • Allows shared executables
  • Supports demand paging
  • Uses a unified memory
  • Supports swap space
the linux kernel con t
The Linux kernel (con’t)
  • Uses dynamically shared libraries extensively
    • Allows full library linking
  • Supports a number of file systems
    • DOS
    • OS/2
  • Ideally suited for application development
the linux kernel con t11
The Linux kernel (con’t)

linux and dos
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

linux and tcp ip
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
linux environments

  • Text-based
  • Graphical user interface (GUI) – called “X” or “X Window”
    • Very popular, especially with users new to Linux
      • KDE
      • GNOME
importance of linux s xfree86
Importance of Linux’s XFree86
  • XFree86 is Linux’s GUI
  • Easy to use
  • Very similar to Windows environment
    • Windows users can make easy transition
  • Can install and run Windows applications
