📖 1. Router & Data Routing

🔑 Key Concepts & Definitions

• Router: A network device that connects multiple networks and directs data packets along optimal paths to their destinations.
• Data Routing: The process of selecting paths in a network along which to send data packets from source to destination.
• Topology: The physical or logical layout of a network; common types include Star, Bus, and Ring.
• Bandwidth: The maximum data transfer rate of a network connection, measured in bits per second (bps).
• Modulation: The process of converting digital signals into analog signals for transmission over a communication channel.
• IP Address (IPv4): A unique 32-bit numerical label assigned to each device on a network, written in decimal format separated by dots (e.g., 192.168.1.1).
