In computing, what is a model?

A model in computing refers specifically to a simplified version of a system that is designed to help in understanding, analyzing, or testing that system. By abstracting certain details, models allow developers, engineers, and analysts to focus on essential components and interactions without getting overwhelmed by complexity. This simplification is crucial in various areas of computing, such as software development, system design, and simulations, where grasping the overall structure and behavior of a system is needed to make informed decisions and predictions.

In practical applications, models can take various forms, such as diagrams, mathematical representations, or prototypes. They serve as tools to facilitate experimentation and comprehension, ultimately assisting in validating theories or designs before those systems are fully constructed or implemented. This is particularly helpful in situations where creating the complete system would be time-consuming or resource-intensive.
