In Access and in databases in general each field in a database table is of a certain data type. The data type determines what type of data a field can hold. A field of the text data type can hold text, a field of the number data type can hold numbers and a field of the data/time data type can hold date and time values.
Access actively checks what type of data is entered into a field and Access will disallow the entry of data into a field that doesn't conform to the field's data type. Access won't allow you to put text into a field of the Number data type, for example.
So, data types are a way to restrict the entry of data into a field. Internally, the database uses different strategies for the storage and retrieval of different data types.

In Access tables, you can apply several data types to a primary key, including AutoNumber, Number, Text, and Date/Time.

The Number and Text data types can also be used, depending on the nature of the data being stored, while Date/Time may be used for unique timestamps. However, it's essential that the primary key values remain unique and not null.
