Linux is a free operating system, and Puppy Linux is a special build of Linux meant to make computing easy and fast.

Puppy Linux enables you to save money while doing more work, even allowing you to do magic by recovering data from destroyed PCs or by removing malware from Windows. See these example articles: recovering files from Windows and safe Internet banking with Puppy Linux.

With Puppy Linux, you can carry your programs and data anywhere.

Easy - Just use a CD or USB flash to boot a PC. Puppy Linux is downloadable as ISO, an image that can be burned to CD or DVD.

Fast - Because Puppy is small, it can live in your PC's memory and be ready to quickly execute your commands, whereas in other systems, programs are first read from drive storage before being executed.

Save Money - Even if your PC has no hard disk (ex, broken hard disk), you can still boot Puppy via CD or USB and continue working. Old PCs that no longer work with new systems will still work good-as-new with Puppy.

Do More - Puppy boots in less than a minute, even in old PCs, and it does not require antivirus software. Administering Puppy is quick and minimal. With Puppy, you just have to take care of your data, which you can easily save to USB flash (Then forget about your operating system!). Your data can be read by other computers.

Do Magic -Help your friends suffering from computer malware by booting Puppy and removing malware from their PC (use antivirus that is built-in or can be installed in Puppy). Example - bad Autorun.inf is easily removed by Puppy (Just delete it as well as its companion exe program). If your friend thinks that she has lost data from her corrupted hard disk, boot Puppy and try saving her data!
Carry Anywhere (Portable) - Because Puppy is able to live in CD/DVD or USB flash, as well as save data to these same devices, you can carry your programs and data 
with you.

Are you now ready for Puppy? Keep these important reminders before using Puppy:

You don't have to install Puppy (to hard disk) to use it. Simply burn the ISO to CD/DVD and boot the PC or laptop with it. Once booted, you can then install it to USB flash (see the Setup menu), so you can use it for booting the PC when a CD is not available.

You don't have to save data to hard drive to work with Puppy. You can save data to USB flash or even to Internet storage (like www.drop.io ). When installed to USB flash, Puppy consumes only a little over 100 MB, or about 256 MB with OpenOffice. You can use the same USB flash (where Puppy is installed) for saving data.
