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.

Name two different ways you can bring up the my computer folder
sweet [91]

The My Computer folder is a multipurpose tool and is a gateway to all the data stored in the computer. This folder sits at the top of your laptop or PC. It can be found on your computer’s desktop, on the start menu and within the windows explorer. <u>Clicking or double clicking on these options will bring up the My Computer folder. </u>

<u>Another easier way of doing this is to hold down the windows + E combination keyboard keys.</u>

Your friend really likes talking about owls. Write a function owl_count that takes a block of text and counts how many words the
andriy [413]
Text = “ I really like owls. Did you know that an owls eyes are more than twice as big as the eyes of other birds of comparable weight? And that when an owl partially closes its eyes during the day, it is just blocking out light? Sometimes I wish I could be an owl.

word = ‘owl’
texts = text.lower()
owlist = list(texts.split())
count = text.count(word)
num = [owlist, count] #num has no meaning just random var
print(num)


Alter in anyway you want so that you can succeed. ✌

grandymaker [24]

Answer:

       if (option1.equals(option2)){

           rsvp = true;

       }

       System.out.println(rsvp);

A full program is given in the explanation section

Explanation:

import java.util.Scanner;

public class Option {

   public static void main(String[] args) {

       boolean rsvp = false;

       int selection;

       String option1,option2;

       Scanner in = new Scanner(System.in);

       option1 = in.next();

       option2 = in.next();

       if (option1.equals(option2)){

           rsvp = true;

       }

       System.out.println(rsvp);

   }

}

Paladinen [302]

Answer:

Option B; 30 SECONDS OR LESS.

Explanation:

Short-term memory, also known as primary or active memory, is the information we are currently aware of or thinking about.

When short-term memories are not rehearsed or actively maintained, they last mere seconds.

Most of the information kept in short-term memory will be stored for less than 30 seconds (approximately 20 to 30 seconds), but it can be just seconds if rehearsal or active maintenance of the information is not done.

Therefore, Anita likely will be able to retain the information in short-term memory, without additional processing, for 30 SECONDS OR LESS.
