A bridge is a Data Link layer network device that logically separates a single network into two segments or collision domains in Ethernet networks. It operates by examining the MAC addresses of the incoming frames and forwarding them only to the appropriate segment, based on the destination MAC address. This helps to reduce collisions and improve network performance by isolating traffic within each segment. Unlike a hub, which simply broadcasts all incoming frames to all connected devices, a bridge selectively forwards frames, making it a more efficient option for segmenting networks.

Fragment-free forwarding method, also known as runtless switching, is a type of forwarding method used in networking. It is a compromise between store-and-forward and cut-through methods. In fragment-free forwarding, the switch waits to receive the first 64 bytes of a frame before forwarding it. This ensures that most collision fragments, which are typically smaller in size, are detected and discarded, reducing the chances of forwarding corrupted or incomplete frames. This method helps to improve network performance and reduce the possibility of transmitting errors.
