LINUX OPERATING SYSTEM

Overview of UNIX/ LINUX Operating System

Even after thirty years of its creation UNIX is still regarded as one of the most versatile, flexible and powerful operating systems in the computer world. It was created at Bell Labs in 1970 written in the C programming language, which was developed at the same time. It supports large numbers of simultaneous users, runs with few alterations on many hardware platforms (provides some platform independence) and of course it was and is a simple, elegant, and easy to use (at least compared to its predecessors) Linux is a relatively new UNIX flavor derived from the work of Linus Torvalds, who was interested to develop a UNIX for academic use. Linux is one of the many versions of the UNIX operating system. Working on Linux means working on one of the flavors of UNIX. The main advantage that Linux is absolutely free, you need not spend even the cost CD it can be entirety free downloadable from the Internet. (No registration fees, no costs per user, free updates, and freely available Operating System and Networking Lab source code). It is portable (means can be configured on any processor like Intel, Solaris, etc), dual-bootable, fast, reliable, secure and versatile. These properties make it popular among the System Administrators. While working on it you may realize many more important features and advantages of Linux. Most of the exercises are command line based but similar exercises you can try on your GUI based Linux.

How to install Linux Operating System

  •  You will need the Fedora 10 DVD image that corresponds to your hardware architecture (i386 or amd64), and which can be downloaded from here. When the download is over, burn the ISO image with your favorite CD/DVD burning application (Bracero on Linux or Nero, CD Burner XP, Roxio on Windows) on a blank DVD at 4x speed.

·         It is always recommend having an empty hard drive for a Linux installation (that means no other operating system on it, no Windows), and you must have a minimum of 10 GB free space for the Fedora installation. Great, now let's begin. Insert or leave the DVD in your CD/DVD-ROM device, and reboot the computer in order to boot from the DVD. Hit the F8 or F12 key (depending on your BIOS) to select the CD/DVD-ROM as the boot device. You'll be presented with a very nice Fedora artwork GRUB splash and some options... 


Choose your language...


Choose your keyboard layout... 


Type a name for the computer. It can be anything you want...


Select your location (country/city)..


Enter the root (System Administrator) password. The longer, the better (WRITE IT SOMEWHERE)...



Here, comes the partitioning part! If you have an empty hard drive, all you have to do is click "Next," but make sure the"Remove all partitions on selected drives and create default layout" option is selected. If you don't have an empty hard drive and you still want to install Fedora 10 on your machine, then make sure you select the "Use free space on the selected drives and create default layout" option (10 GB minimum of free space is required). Click "Next"..
 

We also recommend to select the "Encrypt system" option. Enter a password (the  longer, the better) for the encrypted partition...


Click the "Write changes to disk" button when asked...


The hard drive will be formatted and the partitions will be created...


Now, you can select the desired packages...


Hit the "Next" button and everything will be done automatically from now on, just sit back and watch how the packages are copied to your hard drive.The installation process will take about 8-10 minutes (depending on your computer specs and the selected packages).


It starts installing, wait for sometime


When the installation is over, you will get a "Congratulations, the installation is complete" screen. Click the "Reboot" button and your computer will automatically restart...
Remove the DVD from your optical drive. Your brand new Fedora 10 operating system will boot for the first time... 

If you've chosen to encrypt your partition, then you'll be prompted for the password ..
The system will continue to boot and in a few seconds you will see the First Boot Configuration Wizard. Click "Forward" on the Welcome screen...

 Click "Forward" on the License screen... 



Create a regular user for the system...

 Set the date and time...
Click "Finish" and you will see the login screen. Enter the password for the regular user you've just created...
That's it!
