A namespace prefix is a short, globally unique label Salesforce stamps onto packaged component API names so two publishers can ship the same local name without colliding in one customer org. Salesforce prepends the namespace and two underscores, turning an object such as Expense__c into abc__Expense__c. Managed-package installs keep the publisher's prefix in the subscriber org; unmanaged-package installs do not carry the publisher's prefix and instead follow the subscriber org's namespace, or have none.
