What is Case-sensitive?
If something is '''case-sensitive''' [[uppercase]] and [[lowercase]] letters are treated as two different things. This has become common since [[Computer|computerisation]]. But it is not always true. [[Password|Passwords]] are generally case-sensitive, but [[E-mail|emai]]<nowiki/>l addresses are not. [[URL|url]]<nowiki/>s are usually case-senstive but search engines may not be.
