When I use Transmission to do the downloading, I see some figures on the web control panel of Transmission. Those are technical terms. Such as Seeder, Leecher, Ratio, Trackers, Peers, etc.
So the questions come. What is a seeder? What is a leecher?
Let me check it from search engine and put all together.
What is a seeder?
Seeders are people who have already downloaded the whole file and are uploading them. The more seeders the faster the download will go.
What is a Leecher?
Leechers are people who are sharing what they have and are downloading what you have. (It is real BT spirit here.)
