What is byte?
The byte is a digital data unit consisting of eight bits.The byte was historically the number of bits used to encode a single character of text in a computer, and it is thus the smallest addressable unit of memory in many computer architectures.
By using a network time of 1nsec per bit or a time delay of 512nsec per packet.
If network operates itself in 1gbps means the network delivers 125 MB/sec
To copy 64bytes 4 bytes at a time, 320 nsec are needed on each side, or 640 nsec total(source +destination)
Adding the 512-nsec wire time, we get 1132 nsec total. We get 1792 nsec if we need two more copies.
Relocating 64 bytes in 1792 nsec is equivalent to 35.7 MB/sec.

Finding and correcting code flaws is part of debugging. The following are the code errors: group name, Statements in print, declare variables, input declarations.
Debugging is the process of identifying and fixing flaws in computer programs, software, or systems. Bugs are errors or issues that prohibit proper operation.
Debugging techniques include memory dumps, profiling, control flow analysis, unit testing, integration testing, log file analysis, interactive debugging, and monitoring at the application or system level.
The program's class name is U3 L5 Activity Two.
Spaces are not permitted in class names; an underscore should be used instead.
Therefore, U3 L5 Activity Two or U3 L5 ActivityTwo is the proper class name.
The statement in print
Java distinguishes between lowercase and uppercase letters.
The program's print statements start with the little letter s. This is untrue.
The following are accurate statements:
"Enter two numbers," System.out.println;
"is a multiple of" + System.out.println(b + "" + a);
"Is not a multiple of" + System.out.println(b + "" + a);
Statements of declaration and input
Additionally, the input statements are incorrect, and variables a and b were incorrectly declared.
The appropriate answers are:
Integers a and b are equal to scan.nextInt();
The circumstance
The if statement is not formatted correctly.
The right response is: iif(b%a == 0)
Thus, the appropriate code is:
import scanner from java.util;
general class Main
(String[] args) public static void main
new Scanner(System.in) = Scanner scan;
"Enter two numbers," System.out.println;
I = scan.next int a

The behavioral strategy that the mobile devices mainly impact is option d: self monitoring.
What is Behavioral strategy?
Behavioral strategy integrates cognitive psychology and social psychology into the theory and practice of strategic management. By putting strategic management on a solid foundation of reasonable presumptions about human cognition, emotion, and social interaction, it seeks to increase the empirical integrity and practical applicability of strategy theory.
Self-monitoring is a personality attribute that entails the capacity to keep track of and control one's appearance, feelings, and actions in response to social contexts and circumstances. It entails being conscious of your actions and how they affect your surroundings. 2
A technique called self-monitoring trains pupils to evaluate their own conduct and keep track of the outcomes. Self-monitoring does raise or decrease the frequency, intensity, or length of existing behavior, but it does not produce new abilities or knowledge. Teachers also spend less time observing pupils' conduct as a result.

DOM API would be the best bet for achieving the mentioned functionality to update content dynamically
What is DOM API?
By storing the structure of a document—such as the HTML encoding a web page—in memory, the Document Object Model (DOM) links web pages to scripts or programming languages and helps to update content dynamically. Despite the fact that modeling HTML, SVG, or XML documents as objects is not a function of the core JavaScript language, it usually refers to JavaScript.
A logical tree is used by the DOM to represent a document. Every node in the tree, where each branch of the tree ends, is home to objects. Programmatically, the tree can be accessed via DOM methods. They enable you to alter the document's content, style, or organization.
Using DOM API dynamically:
The DOM provides methods for obtaining and modifying elements as well as for handling events by affixing event handlers. These are the techniques:
A document's event handler is attached by the addEventListener() function.
A node from another document is adopted by adoptNode().
The document that was previously opened with the document's output writing stream is closed with the close() function.

An array is stored in a way that allows a mathematical formula to determine each element's position given its index tuple. A linear array, sometimes referred to as a one-dimensional array, is the most basic sort of data structure. Two-dimensional arrays are sometimes referred to as "matrices" since the theoretical concept of a matrix can be expressed as a two-dimensional grid. Although tuples instead of vectors it is the more mathematically accurate counterpart, the term "vector" is occasionally used in computers to reference to an array. In particular, lookup tables are frequently implemented as arrays, and the word "table" is occasionally used as a shorthand for array.

What is dictionary?
A dictionary is a list of words from the lexicon of one or more particular languages, frequently organised alphabetically (or by radical as well as stroke for ideographic languages), and may contain details about usage, pronunciation, etymologies, definitions, etc. It's a lexicographical reference which illustrates how the data are related to one another. The categories of general and specialised dictionaries are broadly distinguished. Instead of including every word in the language, specialised dictionaries include words throughout specialist fields. There is some debate over whether lexicology as well as terminology are two distinct academic disciplines, but lexical items that describe concepts in particular fields are typically referred to as terms rather than words.
