Question

The data structure used for file directory is called

Answer 1

This is a tough question. I’m not sure if I’ll get it right but I’ll try.

Data structures used for file directories typically have a hierarchical tree structure, referred to as a directory structure. The tree has a root directory, and every file in that system has a unique path.

The simplest method of implementing a directory is to use a linear list of file names with pointers to the data blocks. But another way that you can format a file directory is by using a hash table. With this method, the linear list stores the directory entries, but a hash data structure is also used. The hash table takes a value computed from the file name and return the pointer to the file name any linear list.

So I think it’s C. But I’m not 100% sure.

I hope that helps.
