Sometimes you may want to use a different DNS server then the one that is handed out from your networks DHCP server.

Linux is a great operating system and plays nice with other operating systems such as windows. You can easily connect to a windows network share drive with just a few simple steps. This is very handy for a mixed enviorment when sharing files and resources.

To find your IP address on a Windows computer go to Start > Run (You can also use the keyboard short cut windows + "R")

Note: In windows 7 the run option is hidden from the start menu. A quick short cut is to hold down the windows key (located in the bottom left corner of your keyboard by CTRL and FN) and hit the the letter "R".
