Not downloading at all
Utorrent works on the premise that there are many people wanting the file that is being downloaded and many people have the file or parts of it available to be downloaded.
When one person is holding the whole file then they can seed this file so others can download it. As long as they have the file complete and available others can download it normally in blocks such as 4 kb blocks. As they download the blocks then they are available to others to download from them so if you have downloaded 50% of a file then that 50% of the file is available to any others that want to download it.
To this end someone can download part of the file from you and part of the file from another person thus speeding up the download process.
when two people are downloading different parts from the seeder they can also download the parts the other person has downloaded. So each person is helping to speed up the process of getting the file.
Once each person has a complete file then they can seed that file in its' complete form allowing many people to download the file quickly.
Where the torrent system falls over is when the initial person with the complete file stops seeding the file before each person downloading the file has the complete file. If there is any part of the file not contained on at least one downloaders computer then the file will continue to wait till that piece is available before completing the download thus leaving all downloaders without a complete file.
If a file has become dormant where no people are carrying any part of the file then the torrent program sits waiting for any part to become available to start downloading.
