Final answer:
An attribute is a term that describes a property or characteristic of an object, commonly used in computing and databases to specify a particular aspect of a data entity.
Step-by-step explanation:
A piece of information about a particular object is called an attribute. This term is commonly used in computing and database contexts to describe a specification that defines a property of an object, element, or file. It may also refer to the quality, character, or characteristic ascribed to someone or something.
For example, in a database system, an attribute is a description of a particular aspect of a data entity; in an object-oriented programming context, an attribute refers to a property that objects of a class may have.
