Answer: (A) Firewall; implement an ACL on the interface
Explanation:
According to the question, for re-mediate the issue firewall should be implemented the ACL (Access control list) on the given interface. The access control list is one of the type of logic which selectively give permission or deny the number of packet in the system which to through the interface.
Firewall is the type of device that basically examine the traffic in the network system and also make several decisions in the system. ACL is the set of rule which mainly define the route of the packet in the router interface state.
Answer: Scope resolution operator(::)
Explanation: A member function and the constructor can be called within the function easily but for the execution of the these components outside the class , a special operator is required to call the functions. The scope resolution operator(::) preceding with the name of class is thus used for defining of the function outside class.This operator maintains the cope of the function and constructor outside the class.
Answer:
If Corey wants to control the pacing of his presentation, he should adjust his playback settings. In the playback settings, he should select the default setting under "type;" this will allow him to change slides anytime. He should also click the check box under "options" that says "Change slides manually" so he can simply click on the slide whenever he is ready to move on to another slide.
Explanation:
If you don't like that answer, here's another one:
Corey knew he would need a lot of time to explain each point and that his team members would have lots of comments and questions. The best way that Corey should set up his slide show would be to make sure that he has an outline. Also, there should only be one thought per slide (never mix it). It has to be taken into account that he should have fewer words and more images/graphs.
Answer:
Explanation:
import java.util.Array;
public class Items{
public static void main (String {} args){
// a. Set up 4 arrays which hold data about 6 items you want to sell
int [] itemnum = new int[](1,2,3,4,5,6);
int [] quantity = new int[](500,200,350,100,270,300);
double [] price = new double [](10000, 50000,30000, 22000, 26000,100200);
double[] sales = new double [6];
//b. Set up loops to load the itemnum, quantity and price arrays
for(int I=0;I<6;I++)
{
System.out.println("Item "+itemnum[I]);
System.out.println("Item "+quantity[I]);
System.out.println("Item "+price[I]);
}
//c. Set up another loop to calculate values for the sales array.
for(int j=0;j<6;j++)
{
sales[j] = quantity[j] * price[j];
}
//d. Set up another loop to print the item number and sales amount for each transaction
for(int k=0;k<6;k++)
{
System.out.println("Item Number "+itemnum[k]);
System.out.println("Sales Amount "sales[k]);
}
//e. Set up another loop to calculate the total sales of all 6 items
double totalsales = 0;
for(int l=0;l<6;l++)
{
totalsales+=sales[l];
}
//f. print the total sales amount
System.out.print("Total Sales: "+totalsales);
}
}
Answer:
The Internet
Explanation:
Why? The internet has done twice if not thrice what the printing press has done. The printing press allowed for dissemination of information and knowledge to the population through its mechanical movable printing capability and speed of book publishing. However its reach was highly limited by the physical attributes of the machines and having to transfer books and papers in spreading them to certain destinations. This limitation has been eliminated by the internet as one is able to receive a book written today in seconds and not physically but through electronic means. In other words, information need not be transferred physically, also accessbility and cost of getting information has been highly improved with the internet.
