What happens when a circulatory system and computing system are connected by abstraction?
When a circulatory system and computing system are connected by abstraction, it allows for the exchange of information and data between the two systems. This enables the circulatory system to control the computing system and receive feedback from it, allowing for the development of more complex systems. By abstracting the two systems, it allows for the development of powerful medical applications that can monitor and adjust the circulatory system in real time. For example, this could be used to adjust a patient's blood pressure or monitor their heart rate in order to prevent dangerous conditions from developing.
Creating a Shell Script
You will use command line arguments for the x and y values.
Be sure you follow the directions exactly.
Create a shell script named arithmetic_2.sh using Nano (or the GUI text editor if you prefer).
The script needs to perform the following pseudo code in the order shown:
Check to see if the user entered two numbers on the command line following the script name. If not, display an error message and exit, otherwise continue on.
Assign the first argument to a variable named x.
Assign the second argument to a variable named y.
Display the two values.
Divide y by x and display the result.
Save the file, and test it in the terminal. (What must you do before you can run it?)
When you’re satisfied that it works, upload it to Canvas.
If the user fails to supply the two values as arguments on the command line, prompt the user to enter them like you did in the first arithmetic exercise.
Do the above, but if the user gives you only one value as a command line argument, use it for the first one (x), and ask for the second one.
NOTE: Some of you may already know that doing simple division in a shell script usually results in whole number (integer) results. That's OK for the purpose of the exercise, which is to use command line arguments. Dividing by zero is something we wish to prevent, so check the input for x.
arithmetic_2.sh reads two command line arguments for x and y, displays them, checks x is not 0, and displays the result of y/x, while prompting for input if arguments aren't given or only one argument is given.
To create a shell script named arithmetic_2.sh that performs the above operations using command line arguments for the x and y values, the script needs to follow the following pseudo code in the order shown:
Check if the user entered two numbers on the command line following the script name. If not, provide a warning and stop; else, go ahead.Put the first argument into the x variable.Put the second input into the y variable.Display the two values.Check if x is equal to 0. If it is, display an error message and exit, otherwise continue on.Calculate y/x and display the answer.Prompt the user to provide the two values as in the first arithmetic exercise if the user forgets to supply them as arguments on the command line. If the user only gives you one value as a command line argument, use it for the first one (x) and ask for the second one.
Before running the script, make sure to make it executable by running the command chmod +x arithmetic_2.sh in the terminal.

Suppose Tserial = n and Tparallel = n/p + log2(p), where times Tserial and Tparallel are in microseconds. Assume p represents the number of processes.
a) Write the expressions for speed up and efficiency.
b) Find the speedup and efficiency for n = 10000 and p = 16.
The speed up is 15.86 and the efficiency is 0.994.
How to calculate the speedThe speed up (S) is defined as the ratio of the time taken to execute a task serially to the time taken to execute the same task in parallel. It can be expressed as:
S = Tserial / Tparallel
The efficiency (E) is defined as the ratio of the actual speed up achieved to the maximum possible speed up. It can be expressed as:
E = S / p
b) To find the speed up and efficiency for n = 10000 and p = 16, we substitute these values into the expressions for Tserial and Tparallel:
Tserial = 10000
Tparallel = 10000 / 16 + log2(16) = 625 + 4 = 629
S = Tserial / Tparallel = 10000 / 629 = 15.86
E = S / p = 15.86 / 16 = 0.994
So the speed up is 15.86 and the efficiency is 0.994.

To complete the Course class in NetBeans, we need to add data members for ID, Name, and Code, and implement setters and getters for each.
Additionally, we must provide a default constructor and an overloaded constructor that accepts three parameters to update the member variables.
Next, we need to create a driver class with a main method to instantiate the Course class and call its methods to change the ID, name, and code. In the main method, we can create a new instance of the Course class, set its data members using the setters, and retrieve their values using the getters.
Once the code is implemented, we can test and run it to verify that the class behaves as expected. This includes checking that the data members are correctly initialized, that the setters and getters work correctly, and that the overloaded constructor properly updates the member variables. By following these steps, we can ensure that our Course class is functional and ready for use in larger programs.

v). How many resultant relations and what are their cardinalities and degrees at the end of 3NF? 7 Marks
vi). Define the Oracle PL/SQL Scripts to create the resultant relations
The relation Order_Item_Detail requires normalization because it contains redundant data and violates the first normal form (1NF). For example, the Item_ID, Item_Name, Item_Unit_Price, and Item_Description repeat for multiple Order_ID's, which can lead to data inconsistency and anomalies when the data is updated or deleted.
How to convey the informationii). The relation Order_Item_Detail is in the first normal form (1NF), as it meets the requirement of having a single value in each cell of the relation.
iii). The three update anomalies from the relation are:
Insert Anomaly: If we want to insert a new order for an item that does not already exist in the relation, we will have to insert the same item information multiple times.
Update Anomaly: If we want to update the item information, such as the price of an item, we would have to update the same information in multiple rows, leading to potential inconsistencies in the data.
Delete Anomaly: If we want to delete an order, we may end up deleting the item information as well, which may not be what we intended.
iv). To normalize the relation to 3NF, we need to follow the following steps:
Step 1: Create a new relation called Item_Detail with the following attributes:
Item_ID
Item_Name
Item_Unit_Price
Item_Description
Step 2: Create a new relation called Order_Detail with the following attributes:
Order_ID
Order_Date
Item_ID (Foreign Key referencing the Item_ID in Item_Detail)
Step 3: Remove the Item_Name, Item_Unit_Price, and Item_Description attributes from the Order_Item_Detail relation, and replace it with the foreign key, Item_ID, referencing the primary key in the Item_Detail relation.
The resulting relation Order_Detail will have the following structure:
Order_Detail
Order_ID Order_Date Item_ID

A USB port can connect many different peripheral devices together with a single connector, and stands for ____
Universal Serial Bus (USB) is a technology that allows multiple peripheral devices such as keyboards, mice, cameras, printers, and storage devices to be connected to a computer using a single connector.
USB allows multiple devices to be connected to a computer. This is done using a single connector, which is a small plug with four or more pins. This allows users to connect and disconnect devices from the computer quickly and easily. USB is also a faster technology than other older methods of connecting peripherals, as it can transfer data at speeds up to 480 Mbps. This means that USB devices are more reliable, as they can transfer data more quickly and with less errors. Additionally, USB is backward compatible, meaning that it can be used with most computers, regardless of their age. USB is an incredibly useful technology that makes connecting devices to a computer much easier and faster.

For the following code please:
1. Keep scanning from user until user enters -1
2. Store the numbers in ascending order as the user enters
3. Have a loop to check if the number where the number should be and insert it in that index
4. Print out the final array.
import java.util.ArrayList;
import java.util.Scanner;
public static void main(String [] args) {
ArrayList numbers = new ArrayList ();
System.out.println(“Enter numbers one after another. Once done enter -1”);

Explanation:
C/C++ does not allow arrays to be manipulated as a whole; each element must be set or accessed individually. To make operating on whole arrays or contiguous portions of arrays easier, write the following utility functions.
void arrayFill(int *p,int n,int v); // fill n elements starting a p with the value v
void arrayReverse(int *p,int n); // reverse the order of n elements starting a p
void arrayCopy(int *p,int n,int *q); // copy n consecutive elements from q to p
bool arrayEqual(int *p,int n,int *q); // iff n consecutive elements of p and q are equal
You will need to write your own test code to make sure your functions work correctly. The follow is an example of how to do this, but it is unlikely to find all errors.
#include
int main()
{
int a[20] = {1,2,3,4,5,6,7};
arrayReverse(a+2,3);
assert(a[2] == 5);
assert(a[4] == 3);
arrayCopy(a+7,6,a+1);
assert(a[12]==7);
arrayFill(a+13,6,-1);
int b[20] = {1,2,5,4,3,6,7,2,5,4,3,6,7,-1,-1,-1,-1,-1,-1};
assert(arrayEqual(a,20,b));
}
NOTE: Your submission may not use the array index operator ([]). You must use pointers.
Submit your functions without main().
Answer:
#include <assert.h>
void arrayFill(int *p, int n, int v)
{
for (int i = 0; i < n; i++)
{
*p = v;
p++;
}
}
void arrayReverse(int *p, int n)
{
int *q = p + n - 1;
while (p < q)
{
int temp = *p;
*p = *q;
*q = temp;
p++;
q--;
}
}
void arrayCopy(int *p, int n, int *q)
{
for (int i = 0; i < n; i++)
{
*p = *q;
p++;
q++;
}
}
bool arrayEqual(int *p, int n, int *q)
{
for (int i = 0; i < n; i++)
{
if (*p != *q)
{
return false;
}
p++;
q++;
}
return true;
}
Explanation:
The code includes 4 utility functions to make operating on arrays in C++ easier:
arrayFill: This function takes a pointer to an integer (p), the number of elements to be filled (n), and a value to fill the elements with (v). It uses a for loop to iterate through the n elements, starting from the pointer p, and sets each element to the value v.arrayReverse: This function takes a pointer to an integer (p) and the number of elements to be reversed (n). It initializes a pointer q to point to the last element of the array (p + n - 1). Then it uses a while loop to iterate through the elements, starting from the first (p) and last (q) elements, swapping the values of each pair of elements until the pointers meet in the middle.arrayCopy: This function takes two pointers to integers (p and q) and the number of elements to be copied (n). It uses a for loop to iterate through the n elements, starting from the pointer q, and copies each element to the corresponding location pointed to by p.arrayEqual: This function takes two pointers to integers (p and q) and the number of elements to be compared (n). It uses a for loop to iterate through the n elements, starting from the pointers p and q, and compares each pair of elements. If any pair of elements are not equal, the function returns false. If all pairs of elements are equal, the function returns true.Please look at the attachments! I really need help!
