Automatically stores a number that is one greater than the last number used. It is used to identify a record by acting as a Primary Key. A Primary Key is unique and cannot be left blank. Even if a number is deleted, that number will never be used again, ensuring that each record can be uniquely identified. You do not have to enter the value. It will automatically enter itself. You also cannot change it.
An Autonumber field will automatically generate a number for each record, starting with 1 for the first one. The user cannot change it and the same number will not be used again even if it is deleted. It is used to ensure that each record has a field with a unique value, which in a database is known as a Primary Key. A user can set their own Primary Key, but they could use the Autonumber to generate one if they have not got one.

It is a field with a default value, so it is a default value field. Autonumber fields can also put values in themselves, as can calculated fields.
When you use the compact and repair tool, the Auto Number in a table will be reset to one greater than the largest existing AutoNumber value. For example, consider a table with an AutoNumber field that has 10 rows with autonumbered values from 1 to 10. If you delete rows 6, 9, and 10, and then compact and repair the database, the AutoNumber seed will be reset to 9 (1 greater than the maximum AutoNumber value in the table, which in this example is 8). If the table has no data in it, the AutoNumber will be reset to 1.
No. It does not designate any field you put in. That is something you have to do yourself. If you don't designate one, then it will ask you if you want to or if Access can put one in for you. If you allow Access to put one in, then it will insert a nwe field which will be an Autonumber field and this will be inserted at the top and so it will be the first field. It makes sense to have the first field as a key field, which is why it inserts it at the top, before the first field you put in. If you are setting your own, you should put that field in first, though you do not have to.
Access Data Types are : Autonumber, Memo Text, Number, Yes/No, date/time, OLE object, Hyperlink, Currency.
Autonumber in Access is a special data type that, starting at 1, automatically adds a number for each line you add... For example... Say you were entering guests that were coming into a hotel. You would write John Smith into the name field, and the autonumber field would automatically add the number 1 to it. The next record would automatically add 2 into the field. So it would look like 1 John Smith 2 Katy Jones This makes it a more efficient way to write lists. The Autonumber field will not let you change the value, even if other records are removed, so ensuring that each record retains its own number.
