What term describes something in which data is stored?

The correct term that describes something in which data is stored is commonly referred to as a "Container." In data management and database terminology, a container can represent various formats where data is held, such as a file, database, or a more complex structure that organizes and houses data for access and manipulation.

Cells, columns, and rows are parts of a spreadsheet or database table structure where data is organized. A cell is a single data point intersection of a row and a column, while columns and rows represent the vertical and horizontal collections of cells, respectively. These elements work together to display data but do not represent the broader concept of storage themselves. Hence, the term "Container" appropriately encapsulates the idea of a storage unit for data, making it the correct answer.
