In a folder hierarchy, the top level is referred to as which of the following?

Vesnalui [34]

Answer:

B. root

Explanation:

Every user in Linux is assigned a folder from which they can store their files. The interpreter allows you to abbreviate your route with the “~” symbol. The ls command without any additional data shows the files in the current directory, but if after the name of the command a path is written, it shows the files in that path. Therefore, the ls ~ command shows the files in the user's folder.

In addition to the folders and files created by the user or programs, every Linux folder has two subfolders defined by default:

“..”: It is the top level folder in the file hierarchy that contains it. This subfolder is also present in the root of the filesystem (the folder with absolute path “/”), but points to itself.

“.”: It is the folder itself that appears as if it were also a subfolder. It can be considered as a "self-reference" or pointer to itself.

These folders are normal folders in the system for all purposes; that is, they can be used on routes. For example, the path /dirA/dirB/dirC/../fichero2.txt refers to the file that is stored in the dirB folder, since from dirC, the folder .. points to its predecessor, dirB. The following figure shows the interpretation of this route as well as the equivalent of the “..” and “.” Folders.

Suppose you have the following declaration.int[] beta = new int[50];Which of the following is a valid element of beta.(i) beta[0

kompoz [17]

Answer:

The answer is "Option (i)".

Explanation:

In the given question, an array is defined. It is a collection of the same type of data element, which means, array stores either a numeric value or string value at a time.
An array beta is defined, which contains 50 elements. The array elements indexing always starts with 0 which means, the first element of the array will be stored in an index value that is 0. That's why option (i) is correct.

Explanation:

In RDBMS relational database, the keys play an essential role in making the database reliable and relational in which two or more relations (tables) can be divided into a range of relations with the use of diverse types of keys due to which the redundancy decreases and flexibility of data storage increases.

The following are the usage of keys in a database:

It helps in identifying a specific record that is present in the table.

It is used in minimizing the redundancy from the tables.

It is used in removing the multi-valued attributes from the relations.

it helps in connecting one table with others by using Foreign keys.

It is used in maintaining the uniqueness of the data stored in the database.

It helps in identifying the relationship between two or more tables.

Types of keys in a relational database:

PRIMARY KEY: It helps in identifying each record uniquely due to which the redundancy of data can be minimized.

FOREIGN KEY: It is a kind of referenced key that helps in making a relationship between two or more tables. It helps in fetching records by combining two or more tables with the help of different joins.

SUPER KEY: It is a combination of two or more keys that can be selected as primary. It may contain those columns which have repeated values.

COMPOUND KEY: It is a combination of those columns which may not be used independently as the identification of unique records but their combination does.

CANDIDATE KEY: It is a kind of a super key that does not contain repeated records. A primary key can be chosen from candidate keys.
