Explanation:

The view tab on Microsoft Power point is the 9th tab when counting from the left. When clicked, the view tab displays a number of tools that are aimed at visualizing how slides appear.

The ruler function is one of those tools. It is used to ensure that an object is placed or appears at a specific location in the slides. The ruler tool can be found in the Show Box which is the third box from left after Presentation View and Master View.

murzikaleks [220]

Answer:

// here is code in java.

import java.util.*;

// class definition

class SammysRentalPrice

{

// main method of the class

public static void main(String[] args) {

// scanner object to read input from user

Scanner s=new Scanner(System.in);

// ask user to enter year

System.out.print("Enter the rented minutes:");

// read minutes

int min=s.nextInt();

// find hpurs

int hours=min/60;

// rest of minutes after the hours

min=min%60;

// total cost

int tot_cost=(hours*40)+(min*1);

// print hours,minute and total cost

System.out.println("total hours is: "+hours);

System.out.println("total minutes is: "+min);

System.out.println("total cost is: "+tot_cost);

}

Explanation:

Read the rented minutes of an equipment from user with the help of scanner object. Calculate the hours and then minutes from the given minutes.Calculate the cost by multiply 40 with hours and minute with 1.Add both of them, this will be the total cost.

Output:

Enter the rented minutes:140

total hours is: 2

total minutes is: 20

total cost is: 100

For the following code, if the input is negative, make numitemsPointer be null. Otherwise, make numitemsPointer point to numitem

weeeeeb [17]

Answer:

The program to this question can be described as follows:

Program:

#include <stdio.h> //defining header file

int main() //defining main method

{

int* numItemsPointer; //defining pointer variable

int numItems; //defining integer variable

scanf ("%d", &numItems); //input value from user end

if(numItems < 0) //defining if block to check value

{

numItemsPointer = NULL; //assign value to null

printf ("Items is negative\n"); //print message

}

else //else block

{

numItemsPointer = &numItems; //holds address

numItems = numItems * 10; //multiple by 10

printf("Items: %d\n", *numItemsPointer); //print value

}

return 0;

}

Output:

99

Items: 990

Explanation:

In the above program two integer variable "numItemsPointer and numItems" is defined, in which numItemsPointer is a pointer variable and numItems is integer variable, in which we input value from the user end, and an if condition statement is used, that check and calculate the values, which can be described as follows:

In the if block a condition is defined that variable "numItems" is less then 0, if this condition is true so, inside the block, it will assign a value, that is equal to "NULL", and prints its value.
If the condition is not true it will go to the else block, in this block, it will first pointer variable holds the variable address, and multiply the value by 10, and prints pointer variable value.

1. Why do we need the Domain Name System (DNS)?

Shalnov [3]

Answer:

1. Why do we need the Domain Name System (DNS)?

Think about a DNS system like a phonebook. For humans, it's much easier to remember the address of a Web site using a name (like flamingflamingos.eu) rather than an IP address. IPV4 addresses (88.151.243.8) were complicated but nothing compared to IPv6 addresses (2001:0db8:85a3:0000:0000:8a2e:0370:7334). So, we came with the idea of using this central database that keeps the relationships between domain names and IP addresses. Also, if the Web site changes address (or host), that is completely transparent to the user because he doesn't know (nor care!) what's the site's address.

2. Given the domain name www.flamingflamingos.eu, what is the top level domain in this name?

The top level of the domain name is the last part of it, like .com, .ca, .net, .org and so on.

In this case, it's .eu. That might mean the Web site has its activities in Europe mostly, depending on how strict the rules of the .eu registrar (organisation in charge of the administration of a top-level) are.

There are basically 3 categories of top-level domains.

There are the country-dependent ones like .ca (Canada), .us (United States), .mx (Mexico) and so on, more or less restricted to their physical location.

There are the original broadband ones, available to anyone, anywhere, like .com, .net .org, .info and so on.

In the recent years, new top levels were created for niches, like .travel, .club, .law, .photo and so on.

3. How many different nameservers need to be visited in order to find the location of www.flamingflamingos.eu, including the ROOT server?

The first step your computer will do is look in its cache, if not found, it will most likely contact the ISP's recursive DNS server to see if someone has visited that Website recently, it will retrieve the IP address from there.

If not, it will first contact the root server to get the address of the top level .eu DNS server and will contact it. It will tell us which authoritative DNS server stores the data for that domain.

We then contact that last server to get the IP address of that Website.

So, we in total we will have contacted 4 servers

4. How long does this whole process take?

Depending on the network capacity and traffic... but that is around 1-2 seconds maximum. Of course, if the data is in your computer cache, there's no delay at all.

5. Once the location is acquired (IP address 88.151.243.8) what does your computer do with that information?

Once the computer has the IP address, it launches a direct connection to that IP address and the desired port (like 80 for Web connections) and awaits the server's response.
