Which term refers to a block of data made up of a related set of records?

The term that refers to a block of data made up of a related set of records is a file. A file serves as a collection of related records, which can be accessed, modified, or managed as a single unit. For example, in a database context, a file can represent a table that contains records related to a specific entity, such as customers or products.

In contrast, a database is more comprehensive, encompassing multiple files and their relationships. A data structure refers to a specific way of organizing and storing data in a computer program, but it is generally not used to describe a collection of records as a standalone entity. A storage unit broadly refers to any digital space where data can be stored and may not necessarily define the relational aspect of records as clearly as the term file does. Therefore, file is the most accurate term for a block of data made up of related records.
