Final answer:
A torrent client is a program designed to facilitate fast file downloading from P2P networks by connecting to multiple peers simultaneously.
Step-by-step explanation:
A torrent client is a program used to download files quickly from a P2P (peer-to-peer) network. When you use a torrent client, it connects to other users (peers) who have the file you want to download, and portions of the file are downloaded from multiple sources simultaneously. This can greatly increase download speeds as the workload for file distribution is shared among users of the network. Torrent clients are frequently used for downloading large files such as videos, games, and software.
