Inheritance is when an computer object, like a file or folder inherits settings from it's parent. For example, if a use does not have read access to a folder, they also cannot read any files or sub folders of that directory.
In computer science, an object can be a variable, a data structure, a function, or a method. As regions of memory, they contain value and are referenced by identifiers.
In the object-oriented programming paradigm, object can be a combination of variables, functions, and data structures; in particular in class-based variations of the paradigm it refers to a particular instance of a class.
In the relational model of database management, an object can be a table or column, or an association between data and a database entity (such as relating a person's age to a specific person).
