Yao-Jen Chang, Hung Huan Liu, Tsen-Yung Wang, Mobile Social Networks as Quality of Life Technology for People with Severe Mental Illness, IEEE Wireless Communications, June, 2009.

2. You have two notebooks, one in the office and the other at home. How do you synchronize the data on the two NBs?


method 1:
You can connect it form office to your home by a long wire, ex: RS232.
However, you might cost a lot of money to buy the long wire.

method 2:
You can store data in USB storage device, or Portable Disks Then, you can synchronize the data in many NBs.

method 3:
Maybe we could store our data into the web servers. And then, when we link to the Internet, we can download the data from web server. Hence, no matter what NBs, computers I use, the download data is the same.
For example, we could use iGoogle to store our own style of web page. When you sign in, you can get your own web page immediately.But if there are no Internet in your home, you couldn't get the synchronized data.
