What happens as the key length increases in an encryption application?

1 answer:

6 0

The answer is : Increasing the key length of DES would protect it against brute force attacks. Brute force is when the attacker tries every key knowing that one will eventually work. Key length increase proportionally increases the key space, having a keyspace large enough that it takes too much time and money to accomplish a brute force attack.

Cleo finds herself frequently searching for messages from particular senders or with specific subjects. What should she create

blsea [12.9K]

Answer:

The element she can create to increase efficiency for these searches is:

Search Folder

Explanation:

The reasons behind this are that index in the first place indexes by themselves don't facilitate the job of looking quickly at a certain e-mail. Because they show the user all of them. Second, outlook rules are certain guidelines that the user can program to group certain emails and send them to certain folders. However, they don't play a crucial part in quick searches. We have two options that could make this: instant search of folder search. Instant search works by general categories, of emails, events, and contacts. But search folders give the user certain characteristics the emails can have so the user can choose which emails to see. Thus, this is the correct answer.

You are given an array x of string elements along with an int variable n that contains the number of elements in the array. You

Slav-nsk [51]

Answer:

The code to this question can be given as:

Code:

int i,j,count_previous=0,count_next=0; //define variable

for (j=0; j<n; j++) //loop for array

{

if (x[0]==x[j]) //check condition

{

count_previous++; //increment value by 1.

}

for (i=0; i<n; i++) //loop

{

for (j=0; j<n; j++)

{

if (x[i]==x[j]) //check condition

{

count_next++; //increment value by 1.

}

if (count_previous>count_next) //check condition

{

mode=x[i-1];

}

else

{

mode=x[i];

count_previous=count_next; //change value.

count_next= 0 ; //assign value.

}

Explanation:

In the question it is define that x is array of the string elements that is already define in the question so the code for perform operation in the array is given above. In the code firstly we define the variable that is i, j, count_previous, count_next. The variable i,j is used in the loop and variable count_previous and count_next we assign value 0 that is used for check the values of array. Then we define the for loop in this loop we use conditional statement in the if block we check that array of zero element is equal to array of j value then the count_previous is increase by 1. Then we use nested loop It is also known as loop in a loop. In this first loop is used for array and the second loop is used for check array element.In this we use the condition that if array x of i value is equal to array x of j then count_next will increment by 1.Then we use another condition that is if count_previous is greater then count_next then mode of x is decrement by 1. else mode equal to array and count_previous holds the value of count_next and count_next is equal to 0.

Write a C# program named ProjectedRaises that includes a named constant representing next year’s anticipated 4 percent raise for

nydimaria [60]

Answer:

using System;

class ProjectedRaises {

static void Main() {

const float raise = 0.04f;

double salary1 = 0.0f,salary2 = 0.0f,salary3 = 0.0f;

Console.WriteLine("Current salary for each employee: ");

salary1 = Single.Parse(Console.ReadLine());

salary2 = Single.Parse(Console.ReadLine());

salary3 = Single.Parse(Console.ReadLine());

salary1 = salary1 + raise * salary1;

salary2 = salary2 + raise * salary2;

salary3 = salary3 + raise * salary3;

Console.WriteLine("Next year salary for the employees are: ");

Console.WriteLine(Math.Round(salary1));

Console.WriteLine(Math.Round(salary2));

Console.WriteLine(Math.Round(salary3));

}

Explanation:

This declares and initializes variable raise as a float constant

const float raise = 0.04f;

This declares the salary of each employee as double

double salary1 = 0.0f,salary2 = 0.0f,salary3 = 0.0f;

This prompts the user for the salaries of the employee

Console.WriteLine("Current salary for each employee: ");

The next three lines get the salary of the employees

salary1 = Single.Parse(Console.ReadLine());

salary2 = Single.Parse(Console.ReadLine());

salary3 = Single.Parse(Console.ReadLine());

The next three lines calculate the new salaries of the employees

salary1 = salary1 + raise * salary1;

salary2 = salary2 + raise * salary2;

salary3 = salary3 + raise * salary3;

This prints the header

Console.WriteLine("Next year salary for the employees are: ");

The next three lines print the new salaries of the employees

Console.WriteLine(Math.Round(salary1));

Console.WriteLine(Math.Round(salary2));

Console.WriteLine(Math.Round(salary3));

You have an on-premises network that contains several servers. You plan to migrate all the servers to Azure. You need to recomme

Ainat [17]

Answer:

A). Fault tolerance

Explanation:

The Microsoft Azure is described as the cloud computing service that is known for its flexibility, cost-effectiveness, and quick and easy compliance to fulfill the company's requirements.

As per the question, in order to ensure that 'some servers are available in case of a single Azure data center going offline for an increased time period', the recommendation must include the 'fault tolerance' ability of Azure services. Azure infrastructure has the ability to immediately react in case of a failure to restore the servers and its services. In case of hardware failure, crashing of hard-disks, or short-term availability problems with servers, Azure predicts and manages such failures effectively. Thus, option A is the correct answer.
