Answer:
An input device is something you connect to a computer that sends information into the computer. An output device is something you connect to a computer that has information sent to it.
Explanation:
Answer:
It really depends - in general every data structure has its use.
Explanation:
Furthermore, traversing the list will be inefficient because the data items are not contiguous in memory, forcing the CPU to jump all over the RAM memory causing further slowdown.
Answer:
import java.util.Scanner;
public class num4 {
public static void main(String[] args) {
Scanner in = new Scanner(System.in);
int sumOdds =0;
int sumEvens =0;
int num;
do{
System.out.println("Enter positive integers");
num = in.nextInt();
if(num%2==0){
sumEvens+=num;
}
else if (num%2!=0){
sumOdds+=num;
}
}while (num>0);
System.out.println("The sum of evens: "+sumEvens);
System.out.println("The sum of odds: "+sumOdds);
}
}
Explanation:
- Import Scanner class to prompt and receive user input
- Declare the following variables and initialize them int sumOdds =0, int sumEvens =0, int num;
- Create a do....while loop That continously prompts user to enter a positive number. The loop should terminate when a negative number is enters (n<=0)
- Within the while loop use an if condition with the modulo (%) operator to determine even and odd numbers and add to the respective variables
- Outside of the while loop Print sum of odds and sum of evens
On laptops with a smart card reader installed, where is the smart card reader usually located Under the palm rest
<u>Explanation:</u>

Answer:
Rick has identified a cost risk.
Explanation:
Risk is the probability of loss in a given setting. Herein, the risk involved is the inadequate assessment of the costs involved to carry out the project usually as a result of poor pricing evaluation of resources required for the project. At the early stage of every project, effective and efficient cost estimation is needed because it provides a basis for estimation of the total costs, it helps distribute the cost budget, it eases decision making and thereby assuring a level of profitability, everything being equal.
