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).
