When it comes to front end, back end and full stack developer, the difference is determined by :

front end (the visible parts of a website)

back end (the “under the hood” databases and infrastructure)

full stack (a hybrid of both)

And front end developers work on technologies that are used to build front end(which is what clients visiting that website see)of application like HTML,CSS, Javascript ( Node js, Angular are also now used ).

Similarly back end developers work on back end technologies like Node js.

Full stack developers work on both front end and back end developers and know both end technologies as well.

For example :

MEAN Stack developer where

M stands for Mongoose ( Back end database technology )

E stands for Express ( Back end technology)

A stands for angular ( front end technology)

N stands for Node ( back end technology)

In which encryption strategy is the plaintext encrypted one character at a time and each encrypted character depends on that sin

Natasha_Volkova [10]

Answer:

Caesar cipher

Explanation:

In formation technology, cryptography or cryptology is a process of coding or encrypting information, using algorithms and input values in a network, where there is a present of a third party called adversaries or attackers.

There are different types of cryptography, namely, symmetric, assymmetric and hash cryptography.

Ciphers are algorithms used in cryptography to encode (encrypt) or decode (decrypt) information. An example of cipher is the Ceasar's cipher.

Ceasar cipher is a simple type of substitution cipher that encrpts plain text one character at a time and each coded character depends on the single character and a fixed distance value.

Several students are making presentations for a science class. The chart describes the concept that each student will present to

JulsSmile [24]

Question

Student presentation concepts from another source

Letitia - a step-by-step process of breaking down glucose into energy

Mana - repeating process of the steps of the cell division, going from interphase to division, and back to interphase.

Paul - a series of organisms that show similar characteristics and compare them to those that do not

Which best describes the SmartArt graphic layout each student should use?

Answer:

Letitia would use a process, Maria would use a cycle, and Paul would use a relationship.

Explanation:

Letita's assignment requires her to show how glucose can be broken down into energy, this requires a series of steps in s linear fashion, meaning it would be best suited to a process-style diagram.

Marta's project involves showing the steps of the cell cycle: the clue is in the name. This process is not linear, and instead repeats itself, meaning it fits to a cycle diagram (i.e. a circular diagram)

Paul is comparing and contrasting different organisms. Therefore, he should use a relationship diagram to show shared characteristics as well as features that differ.

Lab Assignment 7A For the lab this week, you will sort an array - using any of the sort methods discussed in Chapter 23 or the S

zhuklara [117]

Answer:

See explaination

Explanation:

import java.util.Scanner;

public class sort {

static void lowestToHighest(float arr[][])

{

float temp;

for(int i=0;i<11;i++)

for(int j=0;j<12-i-1;j++) //Using bubble sort to sort

{

if(arr[j][0]>arr[j+1][0])

{

temp = arr[j][0];

arr[j][0] = arr[j+1][0];

arr[j+1][0] = temp;

}

for(int i=0;i<11;i++) //Using bubble sort to sort

{

for(int j=0;j<12-i-1;j++)

if(arr[j][1]>arr[j+1][1])

{

temp = arr[j][1];

arr[j][1] = arr[j+1][1];

arr[j+1][1] = temp;

}

System.out.println("Data in the array after sorting lowest to highest: ");

for(int i=0;i<12;i++)

System.out.printf(arr[i][0]+" "+arr[i][1]+"\n");

}

static void highestToLowest(float arr[][])

{

float temp;

for(int i=0;i<11;i++)

for(int j=0;j<12-i-1;j++) //Using bubble sort to sort

{

if(arr[j][0]<arr[j+1][0])

{

temp = arr[j][0];

arr[j][0] = arr[j+1][0];

arr[j+1][0] = temp;

}

for(int i=0;i<11;i++) //Using bubble sort to sort

{

for(int j=0;j<12-i-1;j++)

arr[j+1][1] = temp;

}

System.out.println("Data in the array after sorting highest to lowest: ");

for(int i=0;i<12;i++)

System.out.printf(arr[i][0]+" "+arr[i][1]+"\n");

}

public static void main(String[] args){

float temperature[][]=new float[12][2];

Scanner input = new Scanner(System.in);

System.out.println("Enter 12 months of highest and lowest temperatures for each month of the year: ");

for(int i=0;i<12;i++)

for(int j=0;j<2;j++)

temperature[i][j]=input.nextFloat();

System.out.println("Data in the array: ");

for(int i=0;i<12;i++)

System.out.printf(temperature[i][0]+" "+temperature[i][1]+"\n");

lowestToHighest(temperature);

highestToLowest(temperature);

Given an char variable last that has been initialized to a lowercase letter, write a loop that displays all possible combination

Free_Kalibri [48]

Answer:

for (char i='a'; i<='e'; i++){

for (char j='a'; j<='e'; j++){

cout << i<< j<< "\n";

}

Explanation:

The loop runs all characters from the inner while the outer holds one character, by doing so, a will be matched with a,b,c,... Like wise b,c,d,... and on it goes.

Wireless internet is an example of telecommunications.

lawyer [7]

Anything is telecommunication if it has a <span>transmitter</span> and receiver. If you're a Host, then you're hosting (Transmitting) a connection. If you have a router as a customer or service, then you're receiving their signal (transmitting). You're the receiver.
