Key Networking Concepts

  • Devices connect through nodes, each with a unique network address
  • Data is transmitted in packets/frames containing source and destination addresses
  • Network structure (topology) defines connections (e.g., star, ring, bus)

Media Access Control (MAC)

  • Defines rules for how devices access the shared communication medium
  • Prevents data collision and ensures efficient data transmission
  • Critical for maintaining network performance and data integrity

Importance in SCADA

  • Ensures real-time data flow and system coordination
  • Enables centralized monitoring and distributed control
  • Supports scalable and reliable industrial automation systems
