Answer
The different sharing access levels in OWD (Organization-wide sharing) are: "Private," "Public Read Only," and "Public Read/Write."
In the "Private" sharing setting, only the record owner and users above the owner in the role hierarchy have access to the record.
In the "Public Read Only" setting, all users can view records, but they cannot modify them.
In the "Public Read/Write" setting, all users can view and modify records. However, this level of access should be used with caution, as it can result in potential data integrity issues if not managed properly.
