uTorrent is an efficient and feature rich BitTorrent client for Windows sporting a very small footprint. It was designed to use as little cpu, memory and space as possible while offering all the functionality expected from advanced clients. With uTorrent, you can download files faster and contribute by sharing files and bandwidth. Additionally, uTorrent supports the Protocol Encryption joint specification (compatible with Azureus 2.4.0.0 and above, BitComet 0.63 and above) and peer exchange.
BitTorrent is a client. A client in this case is a computer program that follows the rules of a protocol. For example, HTTP (Hyper**** Transfer Protocol) is the protocol used to download *** pages and other ******* - like this page - and your HTTP client (or browser) is the program you use to get those *** pages. Some popular browsers include Microsoft Internet Explorer, Mozilla Firefox, Safari, and Opera. To an extent, they all work the same way because they follow the same set of rules. The BitTorrent client will give you access to the world of ******* on the protocol in a lightweight, fast and reliable package.
