What does UML stand for?

UML stands for Unified Modeling Language, which is a standardized modeling language used in software engineering. It provides a way to visualize the design of a system by using various types of diagrams, including class diagrams, sequence diagrams, use case diagrams, and more. UML is crucial for understanding and documenting systems, as it helps developers communicate their designs and specifications clearly.

The term "Unified" reflects the intention to unify various modeling techniques into a single language that can be used across different types of systems and methodologies. This enhances the language's utility in real-world applications, allowing a common understanding among different stakeholders, including developers, architects, and business analysts.

The other options do not accurately describe UML. "Unified Machine Language" and "Universal Machine Language" suggest a focus on hardware or processing languages, which are not relevant to UML's purpose. "Universal Modeling Language," while somewhat descriptive, is not the correct terminology as the official name includes "Unified" instead of "Universal."
