Which of the following best describes the infrastructure ISPs provide?

Computers and Technology
1 answer:
svet-max [94.6K]3 years ago
4 0

Answer:

cables, towers, and underground tubes

Explanation:

Its certainly the above one, and through this internet service is being provided. So internet service is self-understood, and what ISP firstly provides are cables, underground tubes, and the towers. And it is only these all through which the ISP provides internet service. And remember we are in this question dealing with the infrastructure and not the services or products. Hence, phone service, websites, and files, as well as the emails, search engines, and the videos, are not the solution here as they are not the infrastructure. And ISPs never provide the computers, ethernet cables or keyboards.

Hence, the correct answer is as mentioned in the answer section.

Write a method that computes the sum of the digits in an integer. Use the following method header: public static int sumDigits(l
kifflom [539]

Answer:

The java program for the given scenario is shown below.

import java.util.*;

import java.lang.*;

public class Test

{

   //variables to hold the number, digits and sum of the digits

   //variable to hold number is assigned any random value

   static long num=123;

   static int sum=0;

   static int digit;

   static int s;

   //method to add digits of a number

   public static int sumDigits(long n)

   { do

       {

           digit=(int) (n%10);

           sum=sum+digit;

           n=n/10;

       }while(n>0);

       return sum;

   }

public static void main(String[] args) {

    s = sumDigits(num);

 System.out.println("The sum of the digits of "+num+ " is "+s);  }

}

OUTPUT

The sum of the digits of 123 is 6

Explanation:

1. The variables to hold the number is declared as long and initialized.

2. The variables to store the digits of the number and the sum of the digits are declared as integer. The variable, sum, is initialized to 0.

3. The method, sumDigits(), is defined which takes a long parameter and returns an integer value. The method takes the number as a parameter and returns the sum of its digits.

4. Inside method, sumDigits(), inside the do-while loop, the sum of the digits of the parameter is computed.

5. Inside main(), the method, sumDigits(), is called. The integer value returned by this method is stored in another integer variable, s.

6. The sum of the digits is then displayed to the console.

7. All the variables are declared outside main() and at the class level and hence declared static. The method, sumDigits(), is also declared static since it is to be called inside main().

8. In java, the whole code is written inside a class since java is a purely object-oriented language.

9. In this program, object of the class is not created since only a single class is involved having main() method.

10. The program can be tested for any value of the variable, num.

11. The file is saved as Test.java, where Test is the name of the class having main() method.

Apakah ada yang bisa menjelaskan potongan source code ini?
GarryVolchara [31]

This code attempts to fuse two strings together. So,

fuse("Apple", "Banana")

would return "ABpapnlaen a"

However, there are a couple of things wrong with this code:

- The for loop is incomplete (probably a copy paste error)

- It is unclear from the code if the array jawaban will overflow if kata1 and kata2 are large (it probably will)

- Biggest problem: the jawaban array is declared on the stack, which means it will be cleaned up when the function returns. So the caller of this function will reference unallocated memory! This is a huge bug!!

Consider two different implementations, M1 and M2, of the same instruction set. There are three classes of instructions (A, B, a
Margaret [11]

Explanation:

A.)

we have two machines M1 and M2

cpi stands for clocks per instruction.

to get cpi for machine 1:

= we multiply frequencies with their corresponding M1 cycles and add everything up

50/100 x 1 = 0.5

20/100 x 2 = 0.4

30/100 x 3 = 0.9

CPI for M1 = 0.5 + 0.4 + 0.9 = 1.8

We find CPI for machine 2

we use the same formula we used for 1 above

50/100 x 2 = 1

20/100 x 3 = 0.6

30/100 x 4 = 1.2

CPI for m2 =  1 + 0.6 + 1.2 = 2.8

B.)

CPU execution time for m1 and m2

this is calculated by using the formula;

I * CPI/clock cycle time

execution time for A:

= I * 1.8/60X10⁶

= I x 30 nsec

execution time b:

I x 2.8/80x10⁶

= I x 35 nsec
