Final answer:
In Microsoft Access, a smaller portion of a worksheet that can be imported into a table is known as a named range, which is a group of cells with a specific name for simplified reference and data manipulation.
Step-by-step explanation:
Access allows you to import a smaller portion of a worksheet, known as a named range, into a table. A named range is a group of cells that a user has designated with a specific name for easier reference. This is particularly useful when dealing with large datasets, as it allows you to work with, and import, a specific subset of your data into Access.
In other words, by defining a named range in a spreadsheet application like Microsoft Excel, you can then choose to import this predefined collection of cells directly into an Access table. This makes the import process more focused and efficient since you are dealing with a specific area of the spreadsheet that pertains to the data you need, rather than importing entire sheets or workbooks.
