Question

operating system filenames are ______. (1 point) \bigcirc case sensitive \bigcirc all lower case \bigcirc all upper case \bigcirc all ten characters long

Explanation:

Many modern operating systems (like Linux, macOS) treat filenames as case-sensitive, meaning "File.txt" and "file.txt" are distinct. Other options are incorrect: filenames can use mixed case, and there is no universal 10-character length requirement.

Answer:

A. case sensitive
