Final answer:
Internal services are delivered within the same organization, while external services are provided to external customers.
Step-by-step explanation:
The correct statement is 1 only. Internal services are delivered between departments or business units within the same organization, thereby serving the internal needs of the organization. For example, the IT department providing technical support to the HR department is an internal service. On the other hand, external services are those delivered to external customers.
These customers are entities outside of the organization that receive services from the organization. Examples of external services include a software company providing support to its customers or a consulting firm offering services to clients. Therefore, statement 2 is incorrect as it incorrectly characterizes what external services are.
