IGCSE ICT Chapter 6.2 - Modelling Applications

They are less expensive than building the real thing.

They allow for various scenarios to be tested safely.

They can predict the behavior of systems with complete accuracy.

They can be faster than real-life applications.

Models can be faster than doing the real thing.

Models can sometimes be more expensive than building the real thing.

Models are only as good as the data entered into them.

Models always accurately predict future behavior.

They trust the computer model more than the real thing.

There will always be a difference between the results from modeling and reality.

The computer models are too expensive.

The simulations take too long to run.
