Explain following network devices: i. Bridge ii. Hub ii. Switch iv. Router
i. Bridge: A bridge connects and filters traffic between two or more network segments, operating at the data link layer (Layer 2). It reduces network traffic by dividing a large network into smaller segments and only forwarding necessary data.
ii. Hub: A hub is a basic networking device that connects multiple computers in a network, operating at the physical layer (Layer 1). It broadcasts incoming data to all ports, leading to potential collisions and inefficiencies.
iii. Switch: A switch connects devices within a network and operates at the data link layer (Layer 2). It intelligently forwards data to the specific device based on MAC addresses, reducing collisions and improving network efficiency.
iv. Router: A router directs data between different networks, operating at the network layer (Layer 3). It uses IP addresses to determine the best path for data to travel, enabling communication between different networks and managing traffic efficiently.
