When writing shell scripts and using an if statement to determine whether a set of code should be executed,  the proper syntax to end the if construct is  fi.

A program is guided to make decisions based on predetermined criteria using the IF statement, which is a decision-making statement. If a certain condition is satisfied (TRUE), one piece of code is run, and if it is not, another set of code is run, and so on.

Conditionals are programming language directives used in computer science to handle decisions. If a programmer-defined boolean condition evaluates to true or false, conditionals will execute a different computation or take a different action.

Therefore, For example, if (score >= 90) grade = "A," the following example will demonstrate that the number is positive if its value is greater than or equal to 0. Number is negative is displayed if the value of the number is less than 0.

A data type that separates the logical properties from the implementation details is called a data abstraction data type.

Data abstraction is the process of reducing a specific set of data to a condensed illustration of the total. In general, abstraction is the process of stripping something of its characteristics in order to reduce it to its core components. In order to accomplish this, data abstraction provides a condensed version of the underlying data while concealing its complexity and related procedures. When using a database management system and object-oriented programming (OOP), data abstraction is frequently employed in computing (DBMS).

Data abstraction is a typical technique used by modern programming languages that use OOP approaches to hide the low-level details of the programming constructs that define the underlying logic, which in turn simplifies and speeds up the development process.

Physical addresses contain 15 bits, while logical addresses have 16 bits. On the other hand, a physical address provides location information.

Physical address refers to a program participant's home address, place of employment, or place of attendance. A person's street, street number, and municipality make up their physical address.

A 64-page logical memory unit.

= 2⁶ pages

word count divided by 1024 equals 210

Thus, total logical memory equals 26 x 210, or 216.

A logical address will therefore have 16 bits.

Physical memory equals 32 frames.

25 frames is word count divided by 1024 equals 210

The statement that is true about dictionaries is option A) Dictionary keys are immutable.

A dictionary is a changeable, unordered Python container used to store mappings between distinct keys and values. Curly brackets () are used for dictionaries, as well as key-value pairs with commas between them (,).

Note that A dictionary's keys cannot be accessed using its values, but its values can be obtained using its keys. Since dictionaries themselves are mutable, entries can always be added, deleted, or modified.

Therefore, an immutable type must be used for a dictionary key. An integer, float, text, or Boolean value, for instance, can be used as a dictionary key. However, since dictionaries and lists are both mutable, neither one can act as a dictionary key for the other.

Specifying encoding is very important because it serves as a character set for the document. If it is not done, the process will be idle and HTML parsing will not start early.

Another reason to specify it is to ensure that data is properly translated for consumption in other systems as well. For instance, special characters or binary data may occasionally be displayed on a web page. Data will be correctly utilized and will not be alien by way of encoding.

In practical circumstances, it is essential to notice the number of bytes used for data representation. To decide which one is appropriate, one can check the browser support for the selected encoding. There will be names of the encoding that should not be used.

Encoding is the process of arranging a string of characters (letters, numbers, punctuation, and some symbols) in a particular format for quick transmission or storage. The process of converting an encoded format back into the original string of characters is known as decoding.
