A list is a collection of data stored in columns and rows, similar to a spreadsheet.
The kind of data stored in each column is determined by you and can be such things as text, numbers, multiple choice, currency, dates and times, yes/no, calculated data, and others.
Besides row-and-column views, you can also arrange data in a gallery view that emphasizes pictures, or a calendar view.
