<p data-start="58" data-end="567">Bridges & Routers are essential components in computer networking, each serving a unique purpose in managing data flow. A <strong data-start="180" data-end="190">bridge operates at the data link layer (Layer 2) of the OSI model. Its primary function is to connect and filter traffic between two or more network segments, making it ideal for reducing collisions and segmenting traffic in a local area network (LAN). By analyzing MAC addresses, bridges determine whether to forward or block data packets, thus improving overall network efficiency.

<p data-start="569" data-end="995">In contrast, <strong data-start="582" data-end="593">routers function at the network layer (Layer 3) and are responsible for forwarding data between different networks. Routers use IP addresses to determine the best path for data to travel, making them vital for connecting devices across multiple networks, such as linking a home network to the internet. They also perform Network Address Translation (NAT) and provide firewall capabilities to enhance security.

<p data-start="997" data-end="1393">While both Bridges & Routers handle data transmission, their applications differ. Bridges are generally used to expand or segment networks within the same IP range, while routers connect distinct networks and manage traffic between them. In modern networking environments, routers often incorporate bridging functions, allowing devices to enjoy the benefits of both technologies in a single unit.



<p data-start="1395" data-end="1611" data-is-last-node="" data-is-only-node="">In summary, Bridges & Routers play critical roles in enabling seamless communication within and between networks. Understanding how each functions helps in designing more efficient and secure network infrastructures.
