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
