Redirected from Case-sensitive
When a computer compares two words to decide whether they are equal, it may or may not consider words equal which only differ in case.
This is relevant e.g. with regard to:
Some computer languages are case sensitive (Java, C++), while others are case insensitive (Visual Basic). Often, computer passwords are case sensitive and computer "user names" are not, which can be confusing for the naive user[?]. Passwords are often made case sensitive to make them harder to guess, whereas making usernames harder to guess or remember is not an advantage.
It takes more work for a program to ignore case when comparing data. Although it's easy enough when dealing when English text coded in character sets like ASCII or EBCDIC, it becomes far more challenging in a multi-lingual environment, e.g., using Unicode, since case-conversion rules differ between languages.
