Final answer:
Yes, the org-wide sharing default can be set separately for each object in Salesforce, allowing administrators to enforce different sharing settings for different types of data.
Step-by-step explanation:
Yes, the org-wide sharing default can be set separately by object in Salesforce. Org-wide sharing settings are used to specify the default level of access users have to each others' records. Salesforce provides a granular level of control where administrators can set the sharing settings for standard as well as custom objects independently to ensure that they reflect the organization's sharing policies accurately.
For example, an organization might set the sharing default for Opportunities to Private to restrict access, while setting the default for Contacts to Public Read Only to allow all users to view contact information. These settings help in maintaining the balance between protecting sensitive information and facilitating collaboration among users.
