Could explain briefly the purpose of bridge network?

A bridge network connects two or more separate networks, allowing them to communicate as if they were a single network. It operates at the data link layer (Layer 2) of the OSI model, filtering traffic and reducing collisions by segmenting traffic into different collision domains. This enhances overall network performance and efficiency, facilitating better management of network traffic and improving data flow between devices. Additionally, bridge networks can help in integrating different network technologies or extending network reach.
