What is the significant difference between 'simulation' and 'modelling' in network modelling?

• Modelling focuses on representation, simulation predicts behaviour.
• Simulation creates a digital replica, modelling tests it.
• Simulation is for design, modelling for optimization.
• Modelling deals with the physical aspects, simulation with the digital aspects.
• There is no significant difference.

How does 'modelling' help in optimizing a network?

• By designing the physical aspects of the network.
• By creating a digital replica of the network.
• By predicting the behaviour of the network.
• By representing the network for analysis.
• By allowing testing and refinement before implementation.

How does 'simulation' contribute to the analysis of networks?

• By designing the physical aspects of the network.
• By creating a digital replica of the network.
• By predicting the behaviour of the network under different conditions.
• By representing the network for analysis.
• By replicating user behaviour on the network.
