Semiconductor memory is used mainly for primary storage even with its high cost. In another hand, the magnetic tape is the cheap

est storage media and it is commonly preferred only as backup storage! Use your own words to discuss how the storage cost, speed and capacity trade-offs can affect the choice of storage media.

<span>Storage costs are a big factor in choosing the type of storage media, especially for larger projects and firms. Tasks that require large backups tend to move to magnetic (tape) memory because of the relatively low cost and high overall storage capacity. However, when working with projects that require faster memory and access that is instantaneous, chip memory, even at the higher cost, is more preferable since it is always accessible.</span>

Most types of semiconductor memory have the property of random access,which means that it takes the same amount of time to access any memory location. This means that data can efficiently be accessed in any random order.This contrasts with data storage media such as hard disks and CDs which read and write data consecutively therefore, explains why the data can only be accessed in the same sequence it was written.

Semiconductor memory also has much faster access times than other types of data storage; a byte of data can be written to or read from semiconductor memory within a few nanoseconds, while access time for rotating storage such as hard disks is in the range of milliseconds. For these reasons it is used for main computer memory (primary storage), to hold data the computer is currently working on, among other uses.

Storage costs are a big factor in choosing the type of storage media, especially for larger projects and firms. Tasks that require large backups tend to move to magnetic (tape) memory because of the relatively low cost and high overall storage capacity. However, when working with projects that require faster memory and access that is instantaneous, chip memory, even at a higher cost, is more preferable since it is always accessible.

lisabon 2012 [21]

The quote from the text that shows that the author’s purpose is to persuade is D. Critics say that kids stare at computers and TVs all day and do not get enough exercise. The facts stand in counterpoint to this belief.

An argumentative writing prompt is written in order to convince the readers about a particular issue.

According to the author, the fact that children are involved in watching movies, playing games, listening to music, etc doesn't mean that they can't still be productive.

There are some critics that believe that kids stare at computers and TVs all day and do not get enough exercise. This was countered by the author who stated that kids can still engage in exercises or do other productive things.

Write a program that grades arithmetic quizzes as follows: Ask the user how many questions are in the quiz. Ask the user to ente
kirill115 [55]

Answer:

The program in C++ is as follows:

#include <iostream>

using namespace std;

int main(){

   int questions, answer;

   cout<<"Questions: ";

   cin>>questions;

   int answerkey[questions];

   cout<<"Enter answer keys: ";

   for(int i = 0; i< questions; i++){

       cin>>answerkey[i];    }

   int correct = 0;

   cout<<"Enter answers: ";

   for(int i = 0; i< questions; i++){

       cin>>answer;

       if(answer == answerkey[i]){

           correct++;        }    }

   cout<<"Correct answers: "<<correct<<endl;

   cout<<"Percentage correct : "<<(100 * correct)/questions<<"%";

   return 0;

}

Explanation:

This declares the number of questions and the answers submitted to each equation

   int questions, answer;

Prompt to get the number of questions

   cout<<"Questions: ";

This gets input for the number of questions

   cin>>questions;

This declares the answerkey as an array

   int answerkey[questions];

Prompt to get the answer key

   cout<<"Enter answer keys: ";

This iteration gets the answer key for each question

<em>    for(int i = 0; i< questions; i++){</em>

<em>        cin>>answerkey[i];    }</em>

This initializes the number of correct answers to 0

   int correct = 0;

Prompt to get the enter the answers

   cout<<"Enter answers: ";

This iterates through the answer keys

   for(int i = 0; i< questions; i++){

This gets the answer to each question

       cin>>answer;

This compares the answer to the answer key of the question

       if(answer == answerkey[i]){

If they are the same, correct is incremented by 1

           correct++;        }    }

Print the number of correct answers

   cout<<"Correct answers: "<<correct<<endl;

Print the percentage of correct answers

   cout<<"Percentage correct : "<<(100 * correct)/questions<<"%";

Consider the unsigned decimal number 35. What is the value in hexadecimal?<br><br> 3510 = _______ 16
Lena [83]

Answer:

(35_{10}) = (23)_{16}

Explanation:

The Hexa-decimal numbers have base 16 and includes numbers:

0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C, D, E and F

The given steps are performed to convert a decimal number to hexa-decimal number, here to convert decimal number 35 to hexa-decimal number:

  • Divide 35 by 16
  • Note the remainder, r which is 3 here and quotient which is 2
  • Again divide 2 (quotient) by 16 and note the remainder, r' which is 2 and quotient is 0
  • We will stop here as the quotient is now 0. Usually division by 16 is repeated until we get quotient = 0
  • Now arrange the remainder in reverse order to get the hexa-decimal number as r'r
  • The hexa-decimal number is (23)_{16}
