Answer: Let you organize and summarize your data.

Explanation: Data grouping is referred as the making a collection or cluster of data in a report .The group is made for the summarization of the information and makes easily understandable according to the subject or field due to the proper organization.

Other given options are incorrect because it does not provide the total of the report content,attractive form of the data or editing function in report.Thus the correct option is summarizing and organizing the data.

function chocolatebar(dollars){

var dollaramt= dollars;

var i;

for(i=0; i <= dollaramt; i++){

i=i+6

Alert ("you have 1 extra chocolate bar");

A network administrator is planning redundant devices and cabling in a switched network to support high availability. Which bene

a_sh-v [17]

Answer:

Redundant paths can be available without causing logical Layer 2 loops.

Explanation:

Spanning Tree Protocol is used to allow redundancy in the Layer 2 switched networks without creating cycles/circles also called loops.
These loops are called physical loops.
When two parts of the switched network are connected via two or more Layer 2 switches this result in a loop.
This affects the performance of the network as the result of broadcast packets flooding.
STP puts one port of the switch to forward mode and the rest of the ports within the same part of the network to the blocking mode to avoid broadcast packet flooding. STP puts all the ports that are allowing redundant paths to block mode and the one port that is left after this is placed in forward mode.
Spanning Tree Algorithm is used by STP to determine the optimal path of switch to the network.
Bridge Protocol Data Units are used to share the information about the optimal path determined by the spanning tree algorithm with other switches.
This information helps STP to eliminate the redundant paths.
So this is how STP tracks all the links in the switched network and eliminates redundant loops by allowing only one active path to the destination while blocking all other paths.

What is the name of situation where the same data is stored unnecessarily at different places?

Delicious77 [7]

Answer:

Data redundancy.

Explanation:

A database management system (DBMS) can be defined as a collection of software applications that typically enables computer users to create, store, modify, retrieve and manage data or informations in a database. Generally, it allows computer users to efficiently retrieve and manage their data with an appropriate level of security.

A data dictionary can be defined as a centralized collection of information on a specific data such as attributes, names, fields and definitions that are being used in a computer database system.

In a data dictionary, data elements are combined into records, which are meaningful combinations of data elements that are included in data flows or retained in data stores.

Data redundancy is the name of situation where the same data is stored unnecessarily at different places.

Simply stated, data redundancy can be defined as a condition which typically involves storing the same data in multiple storage locations. Thus, data redundancy connotes the unnecessary repetition of the same piece of data (informations) either deliberately or for some specific reasons.

After which problem-solving stage should you take action?

Mumz [18]

Answer:

Option: Making a choice

Explanation:

In a problem solving process, it starts with defining a problem which is the first step that we need to identify the issue.

After that, we should gather the information on the issue that we identify. For example, we are root cause of the problem, what are the possible solutions etc.

Next, we evaluate the information that we collect (e.g. pro and cons of a particular solution).

Next, we make a choice on the solution that we are going to take after further evaluation on all the options we have.

Only after we make a choice, then we can take action based on our chosen solution to solve the problem.

This program outputs a downwards facing arrow composed of a rectangle and a right triangle. The arrow dimensions are defined by

stira [4]

Answer:

Here is the C program:

#include <stdio.h> //to use input output functions

int main(void) { //start of main function

int arrowBaseHeight = 0; //stores value for arrow base height

int arrowBaseWidth = 0; //stores value for arrow base width

int arrowHeadWidth = 0 ; //stores value for arrow head width

int i, j; //to traverse through the rows and columns

printf("Enter arrow base height:\n"); //prompts user to enter arrow base height value

scanf("%d", &arrowBaseHeight); //reads input value of arrow base height

printf("Enter arrow base width:\n"); //prompts user to enter arrow base width value

scanf("%d", &arrowBaseWidth); //reads input value of arrow base width

while (arrowHeadWidth <= arrowBaseWidth) { //iterates as long as the value of arrowHeadWidth is less than or equals to the value of arrowBaseWidth

printf("Enter arrow head width:\n"); //prompts user to enter arrow head width value

scanf("%d", &arrowHeadWidth); //reads input value of arrow head width

printf("\n"); }

for (i = 0; i < arrowBaseHeight; i++) { //iterates through rows

for (j = 0; j < arrowBaseWidth; j++) { //iterates through columns

printf("*"); } //prints asterisks

printf("\n"); } //prints a new line

for (i = arrowHeadWidth; i > 0; i--) { //loop for input length

for (j = i; j > 0; j--) { //iterates for triangle ( to make arrow head)

printf("*"); } //prints asterisks

printf("\n"); } } //prints new line

Explanation:

The program asks to enter the height of the arrow base, width of the arrow base and the width of arrow head. When asking to enter the width of the arrow head, a condition is checked that the arrow head width arrowHeadWidth should be less than or equal to width of arrow base arrowBaseWidth. The while loop keeps iterating until the user enters the arrow head width larger than the value of arrow base width.

The loop is used to output an arrow base of height arrowBaseHeight.

The nested loop is being used which as a whole outputs an arrow base of width arrowBaseWidth. The inner loop draws the stars and forms the base width of the arrow, and the outer loop iterates a number of times equal to the height of the arrow.

The last nested loop is used to output an arrow head of width arrowHeadWidth. The inner loop forms the arrow head and prints the stars needed to form an arrow head.

The screenshot of output is attached.
