Scalability

Definition

Scalability refers to the capability of a system, model, or algorithm to handle a growing amount of work or its potential to be enlarged to accommodate that growth. In the context of advanced computational techniques, such as machine learning and quantum computing, scalability is crucial as it determines how well these systems can process increasing volumes of data or more complex computations without compromising performance.
