The list of processes are all the tasks that windows is performing at that time. The CPU will go through each entry on the list over and over again performing its tasks. The list also is useful for closing programs that wont close and allocating more resources to a certain application.
If you were to open windows media player, an entry will appear on the list called wmplayer.exe. If you want to improve the responsiveness of the application you can right click on the entry and set its priority to above normal etc. while selecting end task will terminate the program.
