What technology uses mathematical algorithms to render information unreadable to those lacking the required key

1 answer:

6 0

Data encryption is the name of the technology that uses mathematical algorithms to render information unreadable to those lacking the required key.

<h3>What is Data encryption technology?</h3>

This is a technology that helps to secure data by applying a technique known as cryptography. What this basically means is that a secret code (or key) is generated which would provide access to the cryptographically stored information, and failure to provide the correct key makes the data or information unreadable.

Give the 16-bit 2's complement form of the following 8-bit 2's complement numbers: (a) OX94 (b) OXFF (c) OX23 (d) OXBCWhich of t

Korvikt [17]

Answer:

Answer is provided in the explanation section

Explanation:

Convert 8-bit 2’s complement form into 16-bit 2’s complement form.

First write value in binary then check for 8 th bit value. If it is positive the upper 8 bits will be zero otherwise will be 1s.

8-bit number Binary of number Insert 8 bits 16-bit number

0X94 1001-0100 1111-1111-1001-0100 0XFF94

0XFF 1111-1111 1111-1111-1111-1111 0XFFFF

0X23 0010-0011 0000-0000-0010-0011 0X0023

0XBC 1011-1100 1111-1111-1011-1100 0XFFBC

Which of the following 16-bit 2’s complement form can be shortened to 8-bits?

16-bit number 8-bit number

0X00BA 0XBA

0XFF94 MSB bits are not zero so we can’t truncate it to 8-bit No

0X0024 0X24

0XFF3C MSB bits are not zero so we can’t truncate it to 8-bit No

Write the definitions of two classes Day and Night. Both classes have no constructors, methods or instance variables. Note: For

Colt1911 [192]

Answer:

class Day

{

}

class Night

{

}

Explanation:

Given

Two classes named: Day and Night

Requirement: Both classes have no constructors, methods or instance variables. should not be declared using the public visibility modifier.

The syntax to define a class in object oriented programming is

modifier class classname {

// Constructor

constructor(variablename) { ......}

// Methods

methods() { ... }

...

}

Access modifiers (or access specifiers) are keywords in object-oriented languages that set the accessibility of classes, methods, and other members. Examples are private, public, protected, etc.

Going by the syntax above to define class Day

Day

private class Day{

// Constructor

constructor(duration)

{

this.duration = duration;

}

// Methods

CalculateDate() { ... }

}

But the question states that both classes have no constructors, methods or instance variables. should not be declared using the public visibility modifier.

So, class Day will be defined as follows

class Day

{

}

It could also be declared using visibility modifiers other than public modifier. So, class Day will be defined as follows

private class Day

{

}

and

protected class Day

{

}

Similarly, class Night can be defined as follows

class Night

{

}

private class Night

{

}

and

protected class Night

{

}

Explanation:

Provided is the code to run this program

Source Code:

import java.util.Scanner;

class PrintJobCost

{

public static void main(String[] args) {

Scanner input=new Scanner(System.in);

System.out.print("Enter print job info:");

String info=input.nextLine();

String size="",type="";

int count=0,i=0,len=info.length();

double cost=0.0;

while(info.charAt(i)!=' '){

size=size+info.charAt(i);

i++;

}

i++;

while(info.charAt(i)!=' '){

type=type+info.charAt(i);

i++;

}

i++;

while(i<len){

count=count*10+Integer.parseInt(String.valueOf(info.charAt(i)));

i++;

}

if(size.equals("Letter"))

cost=cost+0.05;

else if(size.equals("Legal"))

cost=cost+0.06;

else if(size.equals("A4"))

cost=cost+0.055;

else if(size.equals("A5"))

cost=cost+0.04;

if(type.equals("Grayscale"))

cost=cost+0.01;

else if(type.equals("Colored"))

cost=cost+0.10;

cost=cost*count;

System.out.printf("print job Cost:$ %.2f\n",cost);

}

cheers i hope this helped !!!
