case-sensitive

By

Definition:

Computer programs and operating systems that are case-sensitive read names as different if the case of the name is different. For example, on a case-sensitive operating system (like UNIX) the following are three different files:

  • mywebpage.html
  • MYWEBPAGE.HTML
  • myWebPage.html

It is especially important that Web designers on Windows machines pay attention to the case of their file names. Windows is not a case-sensitive operating system, but most Web servers run UNIX or Linux, and both of these are case-sensitive. If you upload a file named "myWebPage.html" you will not be able to access it without the capital letters in your Web URL.

Also Known As: case sensitive
Examples:
  • mywebpage.html
  • MYWEBPAGE.HTML
  • myWebPage.html
