When we talk about functionalities, we typically refer to the features and capabilities of a particular product, system, or software. However, there are several synonyms that can be used interchangeably to describe these functionalities. For instance, one can use the terms "features," "capabilities," "functions," "performance," "operations," "tools," "utilities," "modes," "options," "settings," "services," "modules," "applications," "facilities," and "attributes" to describe the different functionalities of a system or software. While each of these terms may have slightly different connotations, they all ultimately refer to the range of features and operations that a product can provide to its users.
