Record Types in Salesforce

Salesforce Record Types allow us to specify a category of records that display different picklist values and page layouts.

Administrators can associate record types with profiles so that different types of users should see different picklist values and page layouts in the record’s detail page.

Note:
When we create a record type on an object then a new standard record id field gets added to its field list. It stores the record type using which the record is created and used whenever the particular record is edited nexttime.
