What is a program that searches for and identifies items in a database that correspond to keywords, used especially for finding sites on the Web?

• A. Script
• B. Browser
• C. Search Engine
• D. Compiler

Answer: (C)

A search engine is designed to look through a large collection of web pages and find those that match the keywords you type, then present the most relevant results. It builds an index of web content and uses algorithms to rank pages by relevance, making it quick to locate sites that contain your search terms. This is different from a script, which is a small program that performs tasks; a browser, which lets you view web pages; or a compiler, which translates code into an executable form. So the option that best fits is a search engine because its main purpose is to search and identify web content based on keywords.
