π What are Search Engines?
Search engines are like giant online libraries ποΈ that help us find information on the internet. Instead of books, they organize websites and pages. When you type a question or a keyword into a search engine, it shows you a list of websites that might have the answer.
π A Little History of Search Engines
The very first search engines were simple lists of websites. Archie, created in 1990, is considered the first. Later, came others like Yahoo! and AltaVista. But Google, started in 1998, became super popular because it was really good at finding what people were looking for! π
