If you've got a notebook computer, you might be used to edge scroll on the touchpad when running Windows. This is where the right-hand edge of the notebook's touchpad is used as a virtual scrollbar - by running a finger up and down, the currently active window scrolls up and down correspondingly.

By opening a Command Prompt session with administrative privileges, you can use the defragmentation program with various command-line options. (For details, type defrag /? at the command prompt.).
When your web browser or email program connects to another computer on the Internet, it does so through a TCP/IP port.
