OK. so let's say ,for instance, that a new super duper big file (pirated windows :-)) ) came out and everyone is crazy for getting it using torrents.How does a torrent get a life since only a person has it in the beggining and needs to seed it to hundreds?

because usually torrents start by being seeded by one person, from what i've learned while learning to make my own torrent. For example,my upload speed is 15-20KB/S ..it would take days to seed it at least to one other person,and i cant know if that person is also going to seed or just download and run,,,...,,,

Well you start uploading it from somewhere with a bigger up stream connection. It has to start somewhere though, as you surmised. And as you're very clearly only talking about legitimate upload, e.g.linux iso images, then they will come from major locations, e.g. universities with huge band width.

Also, As many private trackers with less upstanding content require memberships and enforce ratios then most people will upload as required.

thanks. lol i wanted to say linux iso instead of pirated windows but i thought oh wait but linux quesstions have the isos on their site so its as simple as downloading from there and seeding further.

i thought it would have been more different as of sending the data on DVD (or bluray) through mail and then they loaded tghat on their pc and seeded it further. i guess i have a complicated mind.. :-\

Suppose you're the first seed. You can only upload slowly. But as soon as another peer gets just one chunk, they can then upload that chunk to more peers. So fairly quickly, every peer is able to upload something. A new torrent that's in high demand will be slow at first, but should fairly quickly improve. That is essentially the "secret" of bittorrent.

"Super seeding" is intended to enhance this. It basically ensures that every chunk gets sent to one other peer, before sending second copies of chunks. It should only be used by initial seeds.
