Answer:

Quality of service (QOS).

Explanation:

In recent computer networking, the convergence of voice, video and text data packet has been made possible. There is no need for a dedicated network for a particular type of packet.

QOS or quality of set is a service rendered to voice or audio packets in VoIP phones to enhance communication.

The email is a digital mailing system that can be used to send all three packets. It enjoys the QOS as voice packets. It is given high preference for transmission and uses the TCP protocol to transmit data reliably.

Answer:

This code fragment will run an infinite loop

Explanation:

This output: Interest 0.0 Will be displayed infinitely. The reason is because the variable year which is initially set to 0 is never updated and as such remains true because the condition is while(year<10). So at the first iteration the statement interest = (principal * year * rate) / 100; evaluates to 0 and this line of code System.out.println("Interest " + interest); prints Interest 0.0. At the next iteration the same evaluation and output takes place and on and on and on....... since the control variable is not changing.

Answer:

Output: 2004 2008 2058  

Explanation:

In the first printf command it will print the address of the variables num, msg1, msg2. And in the second printf command it will print the values of the variables num, msg1, msg2. As the address of the structure is 2004 And the size of the integer is 4 byte so size will increase with 4 bytes and the size of character is 1 byte so it will increase by 1*50= 50 bytes.

Hence, the output is 2004 2008 2058

int b = 0;

for (int i = 0; i<a.length; i++)

{

b++;

}

return b;

}

Answer:

Returns the value of b which is the dimension of the array

Explanation:

The method foo accepts a multi dimension array and returns the dimension of the array. A complete code implementation and call to the method is given below:

public class TestClass {

   public static void main(String[] args) {

   String [ ] [ ] arr = {{"gh","hj","fg", "re","tr"},{"","er","df","fgt", "tr"}};

       System.out.println(foo(arr));

   }

   public static int foo(String [ ][ ] a)

   {

       int b = 0;

       for (int i = 0; i<a.length; i++)

       {

           b++;

       }

       return b;

//The Scanner class is imported which allow the program to receive user input

import java.util.Scanner;

//Class Solution is defined to hold problem solution

public class Solution {

   // The main method which signify the begining of program execution

   public static void main(String args[]) {

       // Scanner object 'scan' is defined to receive input from user keyboard

       Scanner scan = new Scanner(System.in);

       // A prompt is display asking the user to enter number of books

       System.out.println("Please enter number of books: ");

       // the user response is assigned to numberOfBook

       int numberOfBook = scan.nextInt();

       // A prompt is displayed asking the user to enter the number of days over due

       System.out.println("Please enter number of days over due: ");

       // the user response is assigned to numberOfDaysOverDue

       int numberOfDaysOverDue = scan.nextInt();

       //displayFine method is called with numberOfBook and numberOfDaysOverDue as arguments

       displayFine(numberOfBook, numberOfDaysOverDue);

   }

   //displayFine method is declared having two parameters

   public static void displayFine(int bookNumber, int daysOverDue){

       // fine for first seven days is 10cent which is converted to $0.10

       double firstSevenDay = 0.10;

       // fine for more than seven days is 20cent which is converted to $0.20

       double moreThanSevenDay = 0.20;

       // the fine to be paid is declared

       double fine = 0;

       // fine is calculated in the following block

       if(daysOverDue <= 7){

           //the fine if the over due days is less than or equal 7

           fine = bookNumber * daysOverDue * firstSevenDay;

       } else{

           // the extra days on top of the first seven days is calculated and assigned to extraDays

           int extraDays = daysOverDue - 7;

           //fine for first seven days is calculated

           double fineFirstSevenDays = bookNumber * 7 * firstSevenDay;

           // fine for the extradays is calculated

           double fineMoreThanSevenDays = bookNumber * extraDays * moreThanSevenDay;

           // the total fine is calculated by adding fine for first seven days and the extra days

           fine = fineFirstSevenDays + fineMoreThanSevenDays;

       }

       // The total fine is displayed to the user in a nice format.

       System.out.printf("The fine for " + bookNumber + " book(s) for " + daysOverDue + " day(s) is: $%.02f", fine);

   }

}

Explanation:

The program first import Scanner class to allow the program receive user input. Then the class Solution was defined and the main method was declared. In the main method, user is asked for number of books and days over due which are assigned to numberOfBook and numberOfDaysOverDue. The two variable are passed as arguments to the displayFine method.

Next, the displayFine method was defined and the fine for the first seven days is calculated first if the due days is less than or equal seven. Else, the fine is calculated for the first seven days and then the extra days.

The fine is finally displayed to the user.

Counter-controlled repetition requires a condition to determine when the loop should stop, involving initializing a counter, setting a condition for it, and updating the counter within the loop. No boolean or method is strictly required, just the condition.

The question asks which of the following is required for counter-controlled repetition. The correct answer is C. a condition. In computer programming, counter-controlled repetition requires a condition to determine when the repetition should stop. This involves initializing a counter to a starting value, setting a condition for the counter (such as counter < 10), and updating the counter within the loop (often incrementing or decrementing). This loop continues to execute as long as the condition evaluates to true.

For example, in a for loop, you might see something like for(int i = 0; i < 10; i++), where i is the counter, i < 10 is the condition that must be true for the loop to continue, and i++ updates the counter. No boolean or method is strictly required for this process, just the condition that guides the repetition.

l = length(userGuess);

%Create an array.

correctGuess = zeros(1, l);

%Begin the loop.

EvaluateGuesses(3, [3, 4, 5])

Answer:

correctGuess = (myNumber == userGuess);

Explanation:

All you have to do is use the logical operator "==" to signify a relationship between myNumber and userGuess. Whenever the value of myNumber is equal to userGuess, MATLAB will input a "1" into the logical array. It will input a "0" when myNumber does NOT equal userGuess.

Example problem for EvaluateGuesses(3, [3, 4, 5])

correctGuess = (myNumber == userGuess);

The program checks for when 3 is equal to any number in the array userGuess. 3 only equals the first value, so the result is [1, 0, 0].

Therefore, the answer is correctGuess = (myNumber == userGuess);

For n = 100

For n = 200

For n = 400

For n = 800

The faster approach is A(Bx)

Explanation step by step functions:

A(Bx) is faster because requires fewer interactions to find a result: for (AB)x you have (n*n)+n interactions while for A(Bx) you have n+n, to understand why please see the step by step:

a) Function for (AB)x:

function loopcount1 = FirstAB(A,B,x)  

 n = size(A)(1);

 AB = zeros(n,n);

 ABx = zeros(n,1);

 loopcount1 = 0;  

 for i = 1:n

   for j = 1:n

     AB(i,j) = A(i,:)*B(:,j);

     loopcount1 += 1;

   end

 end

 for k = 1:n

   ABx(k) = AB(k,:)*x;

   loopcount1 += 1;

 end

end

b) Function for A(Bx):

function loopcount2 = FirstBx(A,B,x)

 n = size(A)(1);

 Bx = zeros(n,1);

 ABx = zeros(n,1);

 loopcount2 = 0;  

 for i = 1:n

   Bx(i) = B(i,:)*x;

   loopcount2 += 1;

 end

 for j = 1:n

   ABx(j) = A(j,:)*Bx;

   loopcount2 += 1;

 end

end

In this exercise we want to use computer and python knowledge to write the code correctly, so it is necessary to add the following to the informed code:

The correct code that corresponds to the question informed is attached in the photo and we can notice that the faster approach is A(Bx).

So knowing that the information given in the text is that;

For n = 100:

For n = 200:

For n = 400:

For n = 800:

A(Bx) exist faster cause demand hardly any interplay to find a result: for (AB)x you bear (n*n)+n interplay while for A(Bx) you bear n+n, so we have that:

a)Watching the function for (AB)x:

function loopcount1 = FirstAB(A,B,x)  

n = size(A)(1);

AB = zeros(n,n);

ABx = zeros(n,1);

loopcount1 = 0;  

for i = 1:n

  for j = 1:n

    AB(i,j) = A(i,:)*B(:,j);

    loopcount1 += 1;

  end

end

for k = 1:n

  ABx(k) = AB(k,:)*x;

  loopcount1 += 1;

end

end

b) Watching the function for A(Bx):

function loopcount2 = FirstBx(A,B,x)

n = size(A)(1);

Bx = zeros(n,1);

ABx = zeros(n,1);

loopcount2 = 0;  

for i = 1:n

  Bx(i) = B(i,:)*x;

  loopcount2 += 1;

end

for j = 1:n

  ABx(j) = A(j,:)*Bx;

  loopcount2 += 1;

end

Answer:

Before redundancy :100101011100

After checking parity redundancy: 100101010011

Explanation:

First calculate redundant bits ,

We know that the number of redundant bits can be calculated using the following formula:

2^r ≥ m + r + 1

r = redundant bit, m = data bit

total data bits = 8

so ,

2^4 ≥ 8 + 4 + 1

16 ≥ 13

so, redundant bits is 4

Now let they denoted by r1, r2, r4, and r8, as the redundant bits are placed at positions corresponding to power of 2:    1, 2, 4, and 8.  

All the redundant bits are initialized by zero.

For the data word 10011011, we can let  the bits of the data word as  w8,w7, w6, w5, w4, w3, w2, w1

Now , put data bits and redundancy bits  as follows.

d12  d11  d10  d9  d8   d7  d6  d5  d4  d3  d2  d1

w8   w7  w6  w5   r8  w4  w3  w2 r4   w1   r2  r1

 1      0    0      1      0     1     0     1    0    0    0   0

r1 = d1  xor  d3  xor d5  xor d7  xor  d9  xor d11

r1 =  0  xor  0  xor 1  xor 1  xor  1  xor 0

r1 =  1

r2 = d2  xor  d3  xor d6  xor d7  xor  d10  xor d11

r2 = 0  xor  0  xor 0  xor 1  xor  0  xor 0

r2 = 1

r4 = d4  xor  d5  xor d6  xor d7  

r4 = 0  xor  1  xor 0  xor 1

r4 = 0

r8 = d8  xor  d9  xor d10  xor d11   xor d12

r8 = 0  xor  1  xor 0  xor 0 xor  1

r8 = 0

So, the data transferred is

d12  d11  d10  d9  d8   d7  d6  d5  d4  d3  d2  d1

w8   w7  w6  w5   r8  w4  w3  w2 r4   w1   r2  r1

 1      0    0      1      0     1     0     1    0    0    1   1

The bits give the binary number as 0011 whose decimal representation is 3. Thus, the bit 3 contains an error. To correct the error the 3th bit is changed from 1 to 0.

Final answer:

To encode the 8-bit information word 10011011 using the Hamming code and even parity, we would need to insert parity bits into specific positions, resulting in a 12-bit code word composed of the original data and additional parity bits.

Explanation:

The Hamming code is a data protection algorithm used for error detection and correction. To find the Hamming code for the 8-bit information word 10011011 using even parity, you would need to insert parity bits at positions that are powers of 2 (i.e., positions 1, 2, 4, 8,...).

For each parity bit, you would determine whether the number of bits in positions it checks (including itself) is even or odd. In this case, if the number is odd, you would set the parity bit to 1 to achieve even parity, otherwise, set it to 0.

Without working through a specific example, the resulting codeword would be a 12-bit word consisting of the original 8 information bits and an additional 4 parity bits (since 8-bit data would require 4 parity bits for the Hamming encoding).

Answer:

The answer is "Option b".

Explanation:

Answer:

Relational Schema refers to meta-data elements which are used to describe structures and constraints of data representing a particular domain. A relation abide of a heading and a body. A heading is a set of attributes. A body is a set of n-tuples. The heading of the relation is also the heading of each of its tuples.

Explanation:

Defination of relation:

A relation is a property or predicate that ranges over more than one argument

A relation is defined as a set of n-tuples. In both mathematics and the relational database model, a set is an unordered collection of items. In mathematics, a tuple has an order, and allows for duplication.

Relation schema

A relation schema is a collection of meta-data that describes the relations in a database. Which is also called data base schema. This schema can be described as the “layout” of a database or the blueprint that outlines the way data is organized into table.

A "relation" is a table storing data, while a "relation schema" defines its structure, attributes, and constraints without containing data.

The terms "relation" and "relation schema" are both used in the context of relational databases, but they refer to different concepts:

1. Relation:

  - In the context of databases, a relation refers to a table that stores data in rows and columns.

  - Each row in a relation represents a record, and each column represents an attribute or field.

  - Relations are the fundamental structures in a relational database, and they adhere to certain principles such as each cell containing a single value and rows being unique (no duplicate rows).

  - Informally, a relation is often referred to as a table.

2. Relation Schema:

  - A relation schema, on the other hand, defines the structure or blueprint of a relation.

  - It specifies the name of the relation (table) and the attributes (columns) it contains, along with any constraints or properties associated with those attributes.

  - The schema defines the data types of each attribute, any constraints on their values (such as primary keys, foreign keys, or uniqueness constraints), and other properties like nullability.

  - The relation schema provides the framework for creating instances of relations (tables) within a database.

  - It does not contain any actual data but rather describes the structure and properties of the data that can be stored in a relation.

In summary, while a relation represents the actual data stored in a table, a relation schema defines the structure, attributes, and constraints of that table without containing any data itself. The relation schema serves as a blueprint for creating and understanding relations within a relational database.

Final answer:

It may be more appropriate to declare an attribute that contains only digits as a character data type instead of a numeric data type because character data types allow for greater flexibility and can handle other non-numeric characters.

Explanation:

In certain cases, it may be more appropriate to declare an attribute that contains only digits as a character data type instead of a numeric data type. This is because character data types allow for greater flexibility and can handle not only numerical values but also other non-numeric characters.

For example, if you're working with a student ID that consists of digits but also includes special characters like dashes or periods, storing it as a character data type would be more suitable. This way, you can accurately capture and manipulate the entire ID without losing any important characters.

Character data types also allow for better error handling and handling of leading zeros, which can be important in certain scenarios, such as when dealing with bank account numbers or zip codes.

Explanation:

In an entity relationship (ER) model, which is the conceptual illustration of certain entities and the relationships that exist between them, the cardinality of a relationship is the possible (minimum and maximum) number of entity occurrences that can be associated or involved in it.

Note: An entity is a real world object that is being modeled.

For example, a school has many staff members. The school and the staff members are the objects while the relationship between the school and the staff members is one-to-many.

One, many, zero are all values of cardinality.
