What is case sensitive meaning?

Case sensitivity refers to the capability of a system or program to differentiate between uppercase and lowercase letters. In case sensitive systems, uppercase and lowercase letters are treated as distinct characters and are not interchangeable. For example, the words "apple" and "Apple" are considered as different words in a case sensitive system. However, in a case-insensitive system, the words would be considered the same. Case sensitivity is commonly used in programming languages, operating systems, and software applications. It is essential to understand case sensitivity when programming to avoid errors and ensure consistent results.
