It is not a non-functional need for the software to perform well.
Explain about the non-functional requirements?Nonfunctional Requirements (NFRs) specify system characteristics such security, dependability, performance, maintainability, scalability, and usability. Across all of the system's backlogs, they act as limitations or restrictions on system design.
Non-functional requirements are defined as criteria that "do not directly relate to the behavior or functionality of the solution, but rather describe conditions under which a solution must remain effective or traits that a solution must have"
A non-functional requirement (NFR) is a need that provides criteria rather than specific behaviors that can be used to assess how well a system performs. It is a type of requirement used in systems engineering and requirements engineering. Functional requirements, in contrast, define particular behaviors or functions.

A certain range of algebraic integers is represented by an integer data type. Different widths and the presence of negative values are also possible for integral data types. Computers frequently display integers as a collection of binary digits (bits). Diverse computer types and programming languages have a different set of integer size options due to the size of a grouping. Whole numbers are essentially represented by the integer data type (no fractional parts). The integer numbers alternate between different values. Between six and seven, nothing exists.

The team is using File Naming Convention on data organization tool for a data analytics team labels its files to indicate the content, creation date, and version number.
File Naming ConventionA File Naming Convention (FNC) is a framework for naming files in a way that specifies their contents and their relationship to other files. Developing a FNC involves recognizing the project's essential components, as well as the variances and similarities between your files.
File Naming Conventions character:
- Name or initials of the project lead.
- Initials or last name of the file creator.
- Project name/acronym.
- Date of file generation (in YYYY-MM-DD format)
- Version number (with leading zeroes).
A file naming convention (FNC) can help you stay organized by making it simple to identify the file(s) containing the desired information based on its title and by grouping files containing comparable information together. A decent FNC can also aid others in comprehending and navigating your work.
Establishing a successful file naming convention requires time and effort. It should be based on your stated requirements and your team. There are no perfect file naming standards, however there are a few guidelines that can help:
- Determine the optimal ratio of components for your FNC. Too few components generate uncertainty, whereas too many impede discovery and comprehension.
- Utilize appropriate abbreviations. Excessively long file names can be cumbersome and cause problems when transferring information.
- Document your decisions, such as the components you will use (the "project name," for instance), the relevant entries ("DOEProject"), and the meanings of acronyms (DOE stands for the Department of Energy, etc.).
- Your files will be categorized according to the first few components, so begin your FNC with the more general components and then move on to the more particular ones. To order files chronologically, dates should always be yyyy-mm-dd.
- A file naming convention fails if it is not consistently adhered to. Ensure that everyone who must use the FNC is familiar with it and knows how to implement it.

A variable is non-local if it is visible inside a program unit or block but it is declared somewhere else in the program.
So the Correct answer is option B.
Non-local variable scope could be created either by the language nested structures such as subprograms, blocks, or classes, or by creating global variables defined outside of any such units.
The Scope and Lifetime of VariablesIn any programming language, variables have a scope and a lifetime. The scope of a variable is the region of code within which the variable can be accessed. The lifetime of a variable is the period of time during which the variable exists.
In some languages, the scope of a variable is defined by a block. A block is a region of code delimited by curly braces. Variables declared within a block are only visible within that block. Once the code execution leaves the block, the variables are destroyed. This is known as stack-dynamic scope.
The complete question:
Which of the following statements are true?
In some languages, variable scope is defined by a block, in which case a block is typically stack-dynamicA variable is non-local if it is visible inside a program unit or block but it is declared somewhere else in the programNon-local variable scope could be created either by the language nested structures such as subprograms, blocks, or classes, or by creating global variables defined outside of any such unitsThe scope of a local variable starts at its declaration and ends where the block endsLifetime and scope of a variable always overlap since a variable that is live is always visible in all program unitsLearn more about non-local variable :

create a class student with 4 instance variables, 3 constructors, and a print method. write a main method that creates 3 student objects with the 3 different constructors and calls their print() method.
CODE :
public class Student {
//instance variables
private String name;
private int age;
private String major;
private double gpa;
//constructors
public Student() {
this.name = "";
this.age = 0;
this.major = "";
this.gpa = 0.0;
}
public Student(String name, int age) {
this.name = name;
this.age = age;
this.major = "";
this.gpa = 0.0;
}
public Student(String name, int age, String major, double gpa) {
this.name = name;
this.age = age;
this.major = major;
this.gpa = gpa;
}
//print method
public void print() {
System.out.println("Name: " + this.name);

you have just finished developing a new application. before putting it on the website for users to download, you want to provide a checksum to verify that the object has not been modified. which of the following would you implement?
If you have just finished developing a new application, but before putting it on the website for users to download, you want to provide a checksum to verify that the object has not been modified, a process which you must implement is: C. Code signing.
What is SDLC?SDLC is an abbreviation for software development life cycle and it can be defined as a strategic methodology that defines the key steps, phases, or stages for the design, development and implementation of high quality software programs.
What is code signing?In Computer technology, code signing can be defined as a process through which software developer and computer programmers digitally sign executable software codes and scripts in order to confirm the author of the software, as well as guaranteeing that the software code has not been altered (modified) or corrupted, especially through the use of a cryptographic hash so as to validate authenticity and integrity.
In this context, we can reasonably infer and logically deduce that it is important for software developer and computer programmers to implement code signing before making a software available for download on a website.
