Which term describes a program that seeks and identifies items in an online database?
1. search identifier
2. web browser
3. effective searcher
4. search engine
4. search engine
The correct answer is 4. search engine.
The term that describes a program that seeks and identifies items in an online database is "4. search engine."
To arrive at this answer, we can eliminate options 2 and 3, as they do not accurately describe the role of a program in searching and identifying items in an online database.
Option 1, "search identifier," is not a commonly used term and doesn't accurately describe the function of a program in this context.
On the other hand, a search engine is a software program that crawls the web, indexes webpages, and retrieves relevant information in response to user queries. It is specifically designed to search and identify items within an online database or across the internet.
