What is a .torrent file?

This is a small metadata file. Metadata here means that the file contains information about the data you want to download, not the data itself.
Your BitTorrent client needs the .torrent file to connect to the tracker (see below) and download the actual data you're interested in.

What is BitTorrent?

BitTorrent is a peer-to-peer (or P2P) protocol used for the distribution of large files.

What are seeds?

A seed is a client that has a complete copy of the data of a certain torrent. Once your BitTorrent client finishes downloading, it will remain open until you click the Finish button (or otherwise close it). This is known as being a seed or seeding.

What are leechers?

A leecher is a client that is currently downloading the data of a torrent. A leecher does not have the complete file, otherwise it would be called a seed.

What is a tracker?

A BitTorrent tracker is a service on the internet that assists in the communication between BitTorrent clients. When you open a torrent file, your machine contacts the tracker and asks for a list of seeds and leechers to connect to.
