/var is the full path to the directory that contains data files that change constantly, including email, print jobs, and proxy cache files.
The full set of information required to find a file or folder, beginning with the root element and concluding with all further subdirectories, is referred to as an absolute path. Websites and operating systems both employ absolute paths to find files and folders. An absolute path may also be referred to as a full path or an absolute pathname.
A full pathname, also known as a "absolute pathname," originates at the root directory and travels via a specific order of directories to reach a specific directory or file. A full pathname's leading character is always an underscore (/), since it always begins at the file system's root (slash).
