Making a distinction between upper and lower case letters. For example "HELLO" and "Hello" are two different words in a case-sensitive environment. Note: All UNIX machines are case sensitive, when you login to a UNIX machine you must remember to enter your login name and password in the proper case.
A program that knows the difference between upper and lower cased letters. Example: SETUP, Setup, and setup would be considered three different things.
Generally applies to a data input field; a case-sensitive restriction means lower-case letters are not equivalent to the same letters in upper-case. Example: "cat" is not recognized as being the same word as "Cat" or "CAT".
Recognizes only symbols as they had been entered originally. Example: your e-mail is [email protected]. If you type [email protected], the system will not recognize it.
Case-sensitive refers to whether or not you need to type with strict attention to upper- or lower-case characters. Your AT&T Yahoo! password is case-sensitive. If your password is "Password" (which we don't recommend), then "PASSword," "password," or "PassWord" won't work.
Case-sensitive refers to whether or not you need to type with strict attention to upper- or lower-case characters. For example, formula syntax is not case-sensitive, so typing “ABS(3)” is the same as typing “abs(3)”. However, the password for your database connection is almost always case-sensitive, so if your password was “test”, the password “Test” would not work.
