Solution:
Deadlock Conditions
DOS, Windows, OS/2, Macintosh and Unix-based operating systems (OSes) all have file systems in which files are placed somewhere in a hierarchical (tree) structure. A file is placed in a directory (folder in Windows) or subdirectory at the desired place in the tree structure.
File systems specify conventions for naming files, including the maximum number of characters in a name, which characters can be used and, in some systems, how long the file name suffix can be. A file system also includes a format for specifying the path to a file through the structure of directories.
File systems use metadata to store and retrieve files. Some examples of metadata tags include:
1. Date created
2. Date modified
3. File size
