Hi Madhur,
The video tutorials are supplements to a book called "Understanding GIS: An ArcGIS Project Workbook." The book includes the working files on a DVD as well as a download code for a trial copy of the software (180 days). The videos are based on the first edition of the book which was published in 2011. There is now a second edition published in 2013. The videos are still quite relevant, but if you buy the book, you should be sure to buy the second edition. You can get the book directly from Esri or from Amazon.
The working files are not publicly available except with the book.
Let us know if you have more questions.

I would find a laptop with a CD player and record the data to a external hard drive.
Then you could transfer the data from the external hard drive to your laptop.
