ITGS Topic 7 Key Terms of Models & Simulations
Term | Definition |
---|---|
Absolute cell reference | In a spreadsheet, a cell reference which does not change when moved. |
Assumptions | Often made during the construction of a computer model, as part of the simplification process. |
Car crash model | Used to predict the results of car crashes. |
Cell format | In spreadsheets, the properties of a cell such as its colour, font, and cell type. |
Cell range | In spreadsheets, reference to a range of continuous cells. |
Cell reference | In spreadsheets, a combination of row number and column letter to refer to a single cell (e.g. A2). |
Centralized processing | Single computer with multiple processors working on a task. |
CFD | Computational Fluid Dynamics. A technique used to model airflow in computer models. |
Climate model | Computer model used to predict possible future climate change. |
Computer model | Mathematical representation of the real world using computer software. |
Computer simulation | Based on computer models, gives users experience of events such as flying a plane. |
Decision Support System | Use of models or expert systems to aid (business) decision making processes. |
Distributed processing | Use of multiple separate computers working together on a common task. |
Feedback loop | Comparing the results of a computer model to actual (real life) results, and using the differences to improve the model for the future. |
Flight simulator | Simulator hardware and software used to train pilots. |
Formula | In spreadsheets, a combination of cell references and mathematical operations. |
Full motion platform | Hardware device which can move in many directions to increase the realism of simulators. |
Function | Built in features of spreadsheets for performing common calculations. |
Global Climate Model | Computer model used to predict possible future climate change. |
Goal seek | Spreadsheet tool used to determine the required values to meet a certain goal. |
Grid computing | Use of multiple separate computers working together on a common task. |
High performance computing | High speed computing using multiple processors |
Parallel processing | High speed computing using multiple processors |
Prediction | Output of a computer model. |
Relative cell reference | In a spreadsheet, a cell reference which updates when moved. |
Simplification | Difference between a computer model's representation of a process, and the real life process. |
Spreadsheet | Application software for performing numerical calculations and analysis. |
Supercomputer | Fastest computers available, capable of performing trillions of calculations per second. |
Variables | Components of a computer model which can be altered to vary the output. |
Visualisation | Graphical or animated output from a computer model or simulation. |
What-if scenario | Use of a computer model to test the results of different situations and scenarios. |
