Overnet is a peer-to-peer file-sharing network that allows users to share and download files directly from one another. It operates on a decentralized model, meaning there is no central server controlling the network. Instead, each user acts as both a client and a server, contributing to the overall distribution of files. The network uses a unique protocol that enables efficient searching and retrieval of files. Overnet is known for its ability to handle large files and maintain a stable connection, making it a popular choice for users looking to share multimedia content.
