Portable Data Applications - Damn Small Linux

Damn Small Linux (also known as DSL) is a Linux distribution originally conceived as an operating system to run on lower specification systems, including computers which would otherwise come out of use. The distribution contrasts to most other GNU/Linux distributions by ranking hardware requirements of programs above other considerations.
According to the distrowatch site (which measures comparative popularity of GNU/Linux distributions based on page views) as of Nov 06 DSL ranks 8th. This provides evidence of strong enthusiasm for operating systems capable of running on lower-end hardware.
Due to the small size of the complete distribution, it will run on smaller storage devices than most other OSes, including bootable business card, 64Mb USB Flash Drive, CompactFlash card (through IDE connector) and ZIP drive.
DSL is a very versatile 50MB mini desktop oriented Linux distribution.
Damn Small is small enough and smart enough to do the following things:
- Boot from a business card CD as a live linux distribution (LiveCD)
- Boot from a USB pen drive
- Boot from within a host operating system (that's right, it can run *inside* Windows)
- Run very nicely from an IDE Compact Flash drive via a method we call “frugal install”
- Transform into a Debian OS with a traditional hard drive install
- Run light enough to power a 486DX with 16MB of Ram
- Run fully in RAM with as little as 128MB (you will be amazed at how fast your computer can be!)
- Modularly grow — DSL is highly extendable without the need to customize

Portable Data Applications - Mojopac

MojoPac is a PC virtualization product that can turn any portable storage device - an iPod, USB flash or hard drive, even a cell phone or digital camera memory card– into your PC.
Essentially, it turns any storage device into a bootable PC that can store all of your important applications and data on it. To access them,user needs to plug the device into any PC or Mac. MojoPac will boot itself to life and the PC you're working from can look just like your own PC.
Once you've got MojoPac software, you can load all of your favorite applications by reinstalling them on the new drive. That could be Microsoft Outlook, PowerPoint, Quicken or Adobe PhotoShop etc. You can play games, chat, use IM and email, too. Move any documents and files you want to access as well.
When you plug the MojoPac into any PC you can use the PC screen, keyboard, PC mouse…the iPod or flash device acts as your hard disk and you can access all of your applications and documents.

Portable Data Applications - U3

U3 LLC. is a joint venture that is backed by Sandisk and M-Systems. U3 is responsible for the development of a proprietary application design specification created for Microsoft Windows operating systems so that applications can be executed directly from a specially formatted USB flash drive. Applications are allowed to write files or registry information to the host computer, but this information must be removed when the flash drive is ejected.
USB flash drives adhering to the U3 specification are termed “U3 smart drives” by U3.com. “U3 smart drives” differ from traditional USB flash drives because they come preinstalled with the U3 Launchpad, which emulates the Windows OS start menu, and controls program installation.

A general look to flash disks.

They are typically small, lightweight, removable and rewritable. Memory capacity typically ranges from 128 megabytes up to 64 gigabytes, limited only by current flash memory densities, although cost per megabyte increases rapidly at higher capacities due to the expensive components. For example, as of October 2006, flash drives were available in retail stores at US$25 for 512MiB, US$35 for 1GiB, US$60 for 2GiB, US$100 for 4GiB, and US$160 for 8GiB.
USB flash drives have several advantages over other portable storage devices, particularly the floppy disk. They are more compact, generally faster, hold more data, and are considered more reliable (due to their lack of moving parts) than floppy disks. These types of drives use the USB mass storage standard, supported natively by modern operating systems such as Linux, Mac OS X, and Windows.
A flash drive consists of a small printed circuit board encased in a robust plastic or metal casing, making the drive sturdy enough to be carried about in a pocket, as a keyfob, or on a lanyard. Only the USB connector protrudes from this protection, and is usually covered by a removable cap. Most flash drives use a standard type-A USB connection allowing them to be connected directly to a port on a personal computer.
Most flash drives are active only when powered by a USB computer connection, and require no other external power source or battery power source; they are powered using the limited supply afforded by the USB connection. To access the data stored in a flash drive, the flash drive must be connected to a computer, either by direct connection to the computer's USB port or via a USB hub.
History
An original 16 megabyte “disgo”; The 8 MB version is considered to be the first USB flash driveThe flash drive was first invented in 1998 by Dov Moran, President and CEO of M-Systems Flash Pioneers (Israel). Dan Harkabi, who is now a Vice President at SanDisk, led the development and marketing team at M-Systems. His most significant contribution was that the product be self-reliant and free of the need to install drivers. Nearly simultaneous development of similar products was undertaken at Netac and at Trek 2000, Ltd. All three companies have similar and disputed patents. IBM was the first North American seller of a USB flash drive, and marketed an 8 MB version of the product in 2001 under the “Memory Key” moniker. IBM later introduced a 16 MB version manufactured by Trek 2000, and returned to M-Systems for the 64 MB version in 2003. Lexar can also lay claim to a USB flash drive product. In 2000 they introduced a Compact Flash (CF) card having an internal USB function. Lexar offered a companion card reader and USB cable that eliminated the need for a USB hub.
The first flash drives were made by M-Systems and distributed in Europe under the “disgo” brand in sizes of 8 MB, 16 MB, 32 MB, and 64 MB. These were marketed as “a true floppy-killer”, and this design was continued up to 256 MB. Asian manufacturers soon started making their own flash drives that were cheaper than the Disgo series.
Modern flash drives have USB 2.0 connectivity. However, they do not currently use the full 480 Mbit/s the specification supports due to technical limitations inherent in NAND flash.
Flash drives have become iconic as a sort of “fashion statement”, much like the iPod's white ear bud headphones.

With the entering of usb interface to our lives, products became more universal (BY DEFINITION) allowing more products to connect together more easily. USB technology caused to born lots of new products that makes our lives easier. Especially flashdisc and related goods' capabilities for storing, carrying and re-using data; make these products indispensable.
This situation still cause to be created new products. And we, the flashlighter.com crew, will always search the usb world and make you informed.
