What is case insensitive?

Case insensitive refers to the feature in computing where text or characters are treated equally regardless of their capitalization or letter case. For example, when searching for a keyword or term in a search engine, a case-insensitive search would return results that include all instances of that keyword or term regardless of whether they are written in uppercase or lowercase letters. Similarly, in programming languages, variables or functions can be defined as case-insensitive, which means that they can be referenced with different capitalizations without causing errors. Case-insensitivity is commonly used in text manipulation and searching algorithms to reduce user input errors and enhance the user experience.
