Final answer:
External lookups can live in various places depending on the requirements, such as an API, separate modules, or within a database.
Step-by-step explanation:
In computer science and programming, external lookups refer to the process of retrieving data from an external source or database. The location of these external lookups can vary depending on the specific context and requirements of the application. Examples of where external lookups can live include:
- In an API (Application Programming Interface) that connects to a remote server or database
- In a separate function or module within a program
- In a database itself, using queries to fetch data from other tables or databases
The decision of where to store external lookups depends on factors such as performance, security, and maintainability.
