Solution
In an operating system, directory information is typically stored using a data structure known as a Hash table. This is because Hash tables provide very efficient search, insert, and delete operations, which are commonly performed on directory information.
Here's a step-by-step explanation:
-
A directory in an operating system is a file system cataloging structure which contains references to other computer files, and possibly other directories.
-
The main operations performed on directories are: search for a file, add a new file, delete a file, and list all files.
-
To perform these operations efficiently, we need a data structure that can provide fast access, insertion, and deletion.
-
A Hash table is a data structure that fulfills these requirements. It uses a hash function to compute an index into an array of buckets or slots, from which the desired value can be found.
-
Therefore, in an operating system, a Hash table is used for directory information.
So, the answer to your question is "2, 3, and 4".
