Which directory in the FHS stores programs and configuration information that can only be executed and modified by the root user
dlinn [17]

Answer: /sbin

Explanation:

In Linux, FHS describes the directory content and the way in which Operating System files are displayed to the user.

/sbin is a directory that contains executable programs. s/bin is the short form of system binaries. System binaries require root rights to perform specific tasks. /sbin contains binaries that are crucial to boot the system and also to recover and restore the system. /bin directory also contains the commands to boot the system but the main difference between both is that /sbin programs can only be executed by the root user. Examples are fdisk, fsck, root,halt, init, grub, ifconfig.

You have this code in your program.

The line code will create array is G = array('f',[2.5, 3, 7.4])

<h3>What is meant by array ?</h3>

As opposed to defining distinct variables for each value, arrays are used to hold numerous values in a single variable. Set the data type (such as int) and the array name, followed by square brackets [, to construct an array.

An array is a collection of elements with the same type that are kept in nearby memory  locations and may each be separately referred to using an index to a special identifier. There is no need to declare five distinct variables when declaring an array of five int values (each with its own identifier).

In the C programming language, arrays are a derived data type that may contain primitive data types like int, char, double, float, etc.

A desperate employee calls because she has accidentally deleted crucial files from her hard drive and can’t retrieve them from t
konstantin123 [22]

Answer: The file may have been lost due to incompatibility with the operating system, inadequate space on the hard disk drive, or through corruption of the recycle bin.

However, I will have to ask her the following questions:

- name of operating system she is utilizing,

- the time of deletion of files,

- the kind or extension of the deleted file,

- the model number of the computer,

- the size of files created after the deletion of files.

Also, sometimes, deleted files could be irretrievable due to security breeches. The employee may not have the required access to the crucial file but accidentally stumble upon it.

After all of these have been determined, then the error is fixed, and the document/file is restored, and becomes accessible to the employee.
