Linux utilizes what is called "runlevels". A runlevel is a software configuration of the system that allows only a selected group of processes to exist. Init can run the system in one of eight runlevels. These runlevels are 0-6 and S or s. The system runs in only one of these runlevels at a time. Typically these runlevels are used for different purposes. Runlevels 0, 1, and 6 are reserved. For Redhat Linux version 6, the runlevels are: 0 - halt 1 - Single user mode 2 - Multiuser, without NFS (The same as 3, if you don't have networking) 3 - Full multiuser mode 4 - unused 5 - X11 6 - Reboot 1.       level 0 : to halt the system, it reboots the systems again and again after login in 2.       level1 :single user mode, this is a special mode in which only one use ie the super user mode in which limited syst...

First of all ensure u have at least 20 GB of space free in ur hardisk(free means unallocated memory) Once u do that reboot ur system and boot the ubuntu cd from the boot option or change boot preferences from the BIOS. Once your BIOS is configured to boot from CD first, if you have Ubuntu in the drive, you should see the splash screen with a ubuntu written on it. Ubuntu will take a couple of minutes to load up. Just be patient. Select your preferred language. If you have at least 512 MB of RAM, you may want to select Try Ubuntu, as it will allow you to do other things (check your email, browse the web) while you're installing Ubuntu. If you have only 256 MB or 384 MB of RAM, you should select Install Ubuntu. This will give you the same installation screens you see below, but you won't have the rest of the Ubuntu live session running as well. Select your language. There is a new option in the Ubuntu 11.04 and 10.10 installers that asks if you want to install closed sou...

Scalable Vector Graphics (SVG) is a family of specifications of an XML-based file format for describing two-dimensional vector graphics, both static and dynamic (i.e. interactive or animated). The SVG specification is an open standard that has been under development by the World Wide Web Consortium (W3C) since 1999. SVG images and their behaviors are defined in XML text files. This means that they can be searched, indexed, scripted and, if required, compressed. Since they are XML files, SVG images can be created and edited with any text editor, but drawing programs are also available that support SVG file formats. All major modern web browsers have at least some degree of support and render SVG markup directly with the exception of any version of Microsoft Internet Explorer (IE) released for the widely used Windows XP. SVG allows three types of graphic objects: vector graphics, raster graphics, and text. Graphical objects, including PNG and JPEG raster images, can be grouped, s...

minix is the filesystem used in the Minix operating system, the first to run under Linux. It has a number of shortcomings: a 64MB partition size limit, short filenames, a single time stamp, etc. It remains useful for floppies and RAM disks. ext is an elaborate extension of the minix filesystem. It has been completely superseded by the second version of the extended filesystem ( ext2 ) and has been removed from the kernel (in 2.1.21). ext2 is the high performance disk filesystem used by Linux for fixed disks as well as removable media. The second extended filesystem was designed as an extension of the extended file system ( ext ). ext2 offers the best performance (in terms of speed and CPU usage) of the filesystems supported under Linux. ext3 is a journaling version of the ext2 filesystem. It is easy to switch back and forth between ext2 and ext3. xiafs was designed and implemented to be a stable, safe filesystem by extending the Minix filesystem code. It provides the ba...
