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.
The primary key.
Yes, in an Access database, typical field names for a table storing contact information could include "First Name," "Last Name," "Address," and "Phone." These field names help organize and categorize the data within the database, making it easier to manage and retrieve information.

ID
Yes, the FirstName column can be a primary key as long as it satisfies the requirements of a primary key, which include being unique and not null. However, it is generally not recommended to use a person's first name as a primary key as it may not be unique and could lead to data integrity issues.
There are basically two levels of data validation in Access. The first level can be specified by the Access developer in the form of validation rules or input masks. The second level is the actual constraints that Access enforces for input into a field. Access will not allow you to add text into a Number field for example.

primary succession
It is the first column in a table on the left. In a spreadsheet it would be column A. In Access it would the column for the first field. In a table in Word, it would be the first column on the left.
Access is a database, and like a database, it has tables and fields. A table is a group of fields, and a field is likewise a single storage element of a table. For example, if there is a table called "Contacts", it might contain fields such as "First Name", "Last Name", "email", and "Phone." Each field has a limit to the amount and type of data it can contain, and each field can be validated independently of any other field.
