To teach others how
to get an entire operating system into your pen drive. To teach how to carry your applications with you when you are always on the go. To give an overview of portable operating systems To create awareness of this “new” technology To save your cost
Operating Systems: Operating system
means the interface between user and computer hardware. It acts as a host for applications that run on machine, and it coordinates use of computer resources between different tasks. Examples: Microsoft Windows Vista, Microsoft Windows Xp, Ubuntu, Mac OS X Leopard, Mandriva, FreeBSD, etc etc
Applications: Applications are a
set of instructions for processor to execute different functions Examples: Adobe Photoshop, Microsoft Outlook Express, Microsoft Word, GIMP, Microsoft Internet Explorer, Mozilla firefox
Lets check out a few
scenarios: Situation #1: Your PC has an error and hence cannot boot up, but you urgently need to grab an important presentation file from the hard disk Situation #2: You use computers a lot, but hate to download extra programs each time you use different PCs. Maybe, one doesn't have .rar extractor, while another doesn't have your favorite browser with all it's plugins. Situation #3: Your using a PC with restricted access ( normal user account ) and need to use a software which requires an administrator account to install it.
Situation #4: You are
bored at seeing other people's desktop preferences, but you don't want disturb his/her settings. Situation #5: You are too used to Mac OS X look and feel, but your friend's PC is Microsoft Windows, when he/she borrows it to you to use, you are not comfortable with it. All the situation above can be solved and overcome with the use of a portable Operating System. I will be using the recently released DreamLinux version 3.5
Dreamlinux is a free,
modern and modular GNU/Linux system. It can be run directly from a CD/DVD/USBStick and optionally be installed to a HDD, including IDE, SCSI, SATA, PATA and USB drives. Dreamlinux comes with a selection of the best applications designed to meet most of your daily needs. Dreamlinux is based on the venerable Debian Operating System. This means it takes advantage of Debian's best features and adds its own modern development tools, system scripts and applications.
Dreamlinux Desktop Edition 3.5
comes with XFCE Desktop Environment as default. However, nothing prevents anyone from using other desktop environments, thanks to Dreamlinux's modular architecture. For example, you'll find Gnome Desktop Environment available as an XFCE replacement. Shortly, we will make LXDE, TDE and Fluxbox available as well. Multimedia resources Dreamlinux comes with all the codecs and media players needed for a good multimedia experience. Official Site : http://www.dreamlinux.com.br

Live CD/DVD: A live
CD or live DVD is a CD or DVD containing a bootable computer operating system. Live CDs are unique in that they have the ability to run a complete, modern operating system on a computer lacking mutable secondary storage, such as a hard disk drive. Live USB: Live USB flash drives are similar to live CDs/DVDs, but often have the added functionality of automatically and transparently writing changes back to their bootable medium. The term quot;livequot; derives from the fact that these CDs/DVDs each contain a complete, functioning and operational operating system on the distribution medium.
Live Dream Creates an
environment exactly like a Live CD, each time you bootup the pendrive it creates a new session. Whatever you do is not saved. Persistent Dream Same as Live Dream except whatever you do is saved.
n this section, we will
be checking out a solution for people who do not want to change operating systems or “fear” Linux based stuff – Portable Applications. he Portable Applications software that ill be using in this session will be PortableApps.com
PortableApps.com Suite is a
complete collection of portable apps including a web browser, email client, office suite, calendar/scheduler, instant messaging client, antivirus, audio player, Sudoku game, password manager, PDF reader, minesweeper clone, backup utility and integrated menu, all preconfigured to work portably.

FaunOS is a portable,
fully integrated Linux operating system with over 600 preinstalled packages. It is specifically designed to run from a portable USB memory device (such as a USB flash drive).
