"Puppy Linux is one of several minimalistic GNU/Linux distributions that can live on a USB flash memory stick and run entirely in your computer's memory - in Puppy's case as little as 64MB.
"Puppy weighs in at about 100MB, and comes with unfamiliar but practical applications to achieve just about everything you could possibly want for most everyday use in the office or at home.
"There are GNU/Linux distributions such as Damn Small Linux and Slitaz which are a better bet for specialised applications. Damn Small Linux is half the size of Puppy and can be expanded into a full blown Debian installation, a web server or a router, and is better configured for security. Slitaz is even smaller and serves a similar purpose."
