In computers, case sensitivity defines whether uppercase and lowercase letters are treated as distinct ( case-sensitive ) or equivalent ( case-insensitive ). For instance, when users interested in learning about dogs search an e-book , "dog" and "Dog" are of the same significance to them. Thus, they request a case-insensitive search. But when they search an online encyclopedia for information about the United Nations , for example, or something with no ambiguity regarding capitalization and ambiguity between two or more terms cut down by capitalization, they may prefer a case-sensitive search.

28-403: A function is defined in lowercase, it can be called in uppercase, but if a variable is defined in lowercase, it cannot be referred to in uppercase. Nim is case-insensitive and ignores underscores, as long as the first characters match.

70-475: A search is sensitive to case, e.g. in most text editors, word processors, and Web browsers. A case-insensitive search is more comprehensive, finding "Language" (at the beginning of a sentence), "language", and "LANGUAGE" (in a title in capitals); a case-sensitive search will find the computer language "BASIC" but exclude most of the many unwanted instances of the word. For example, the Google Search engine
84-407: A source code tree for software for Unix-like systems might have both a file named Makefile and a file named makefile in the same directory. In addition, some Mac Installers assume case insensitivity and fail on case-sensitive file systems. The older MS-DOS filesystems FAT12 and FAT16 were case-insensitive and not case-preserving, so that a file whose name is entered as readme.txt or ReadMe.txt
98-583: Is basically case-insensitive, with no option for case-sensitive search. In Oracle SQL, most operations and searches are case-sensitive by default, while in most other DBMSes , SQL searches are case-insensitive by default. Case-insensitive operations are sometimes said to fold case , from the idea of folding the character code table so that upper- and lowercase letters coincide. In filesystems in Unix-like systems, filenames are usually case-sensitive (there can be separate readme.txt and Readme.txt files in
112-613: Is saved as README.TXT. Later, with VFAT in Windows 95 the FAT file systems became case-preserving as an extension of supporting long filenames . Later Windows file systems such as NTFS are internally case-sensitive, and a readme.txt and a Readme.txt can coexist in the same directory. However, for practical purposes filenames behave as case-insensitive as far as users and most software are concerned. This can cause problems for developers or software coming from Unix-like environments, similar to

MacOS is somewhat unusual in that, by default, it uses HFS+ and APFS in a case-insensitive (so that there cannot be a readme.txt and a Readme.txt in the same directory) but case-preserving mode (so that a file created as readme.txt is shown as readme.txt and a file created as Readme.txt is shown as Readme.txt) by default.
