Calculate the following issues in bit-level (signed values, two complement arithmetics)

a) 13 + 9 (use word lengths of 5 and 6 bits including the sign bit)

b) 11 – 17 (8-bit word length)

c) 9 * 5 (8-bit word length)

d) a-task using saturative arithmetics

Using pseudocode, write the code that will perform the necessary file operations as described in the short scenario below:

“During registration at a college, student’s details will be captured by a staff member and written to a file called “studentDetails.dat”. The following student details will be captured: name, surname, studentNumber, registeredCourse. The staff member will be prompted for the student details. After every record added to the file, the staff member will be asked whether they would like to add another record. If they choose not to add another record, the program should end.”

Write a PYTHON program that asks the user to enter a student's name and 8 numeric tests scores (out of 100 for each test). The name will be a local variable. The program should display a letter grade for each score, and the average test score, along with the student's name.

Write the following functions in the program: calc_average - this function should accept 8 test scores as arguments and return the average of the scores per student.

determine_grade - this function should accept a test score average as an argument and return a letter grade for the score based on the following grading scale: 90-100 A 80-89 B 70-79 C 60-69 D Below 60 F.

Situation
The ABC team will unveil their latest and greatest product, The FoodieX. The
FoodieX is a mobile application for food delivery from across the city and
nearby neighborhoods. This application will be used by our company to enjoy
food without the concern of going to the restaurant. Your job is to manage the
IT Infrastructure for the staff running the application that has approximately 20
people and ensure infrastructure continuity so they are able to safely launch
The FoodieX.

Your Task
Your supervisor is sending you onsite! Before sending you onsite to complete
the tasks, your supervisor wants to review your plan of attack and review any
questions you have for them.
The current IT infrastructure has some dated hardware and your supervisor
has been leaning towards a Ubiquiti stack. During the previous onsite, your
supervisor noticed there were issues with the firmware and that these systems
were not backed up.
Develop a plan on how you will implement the Ubiquiti Firewall and Switches
and back up their systems.
Your plan should include any planned communication with the client, the
outline of steps to be taken, risk assessment/rollback strategy, and questions
for your supervisor

Design an FIR filter using the fixed window-based method. Use the following high pass filter requirements:

δp = 0.2 dB

δs = − 30 dB

fs = 3000 Hz

f p = 5000 Hz

The sampling frequency is 10000 Hz

Select the optimal fixed window type for the calculations. Present the number of coefficients and the coefficient values of the impulse response of the specified filter

Pick three security concerns of database system and explain how you would address them.

1. Please convert the following decimal numbers to 8-bit binary sign magnitude and to 8-bit 2’s complement. Please show your work if there are multiple steps. Sign Magnitude 2’s complement a. +67 b. +40 c. -28 d. -40

Set the random number Pythonlist to variable x and write the code according to the items below.

(1)Write a code to find the second largest element among List x Element.

(ex.x=[4,4,2,1]->2,x=[5,4,3,1]-4)4)

(2)Write a code to find elements that appear only once in a while.

(ex.x=[4,4,2,1]->[2,1],x=[5,4,3,1]=>[5,4,3,1])

(3)Write a code that generates a list of the frequency of elements for each element of Listx.

(ex.x=[4,4,2,1]->y=[2,2,2,1,1],x=[5,4,3,1]->y=[1,1,1,1])

(4)Write a code to find the value that comes to the center of the list in descending order among the listx members. (*If the number of lists is even, suggest the average value of the two values that come to the center.)

(ex.x=[4,4,2,1]->3=(4+2)/2,x=[5,4,2,1,0]->2)

I am currently using Python and I am a beginner of Python. Tell me the detailed code for the questions (1), (2), (3) and (4).

To address database failure (if the system crashes), what type of redundancy would you recommend to address this?

1. Construct an assembly language program fragment equivalent to the following C/C++ statement:

if (M <= N + 3 && (C == ‘N’ || C == ‘n’))

C = ‘0’;

else

C = ‘1’;

Assume that M and N are 32-bit signed integer variables, and C is an 8-bit ASCII character variable. All variables are stored in memory, and all general-purpose registers are available for use.

how to write a function that clears every pixel and sets it to the Red color. similarly, we have to open the image including height and width and use while loop that accesses each pixel in Python

C++ Heap Tree:  Make a program called "priority_queue" that has the following operations using a heap and simulating a prioritized row of integers with higher priority value.

It has to include the following on the code:

push

Description: Add data to prioritized row

Entry: An integer, which you want to add to the prioritized row

Exit: Nothing
Precondition: n is an integer
Postcondition: The prioritized row contains new data.

pop -

Description: Remove the data with the highest priority from the prioritized row

Entry: Nothing
Exit: Nothing
Precondition: That the prioritized row contains at least 1 data.
Postcondition: The prioritized row is left without the data with the highest priority

top

Description: Returns the value of the data that is with the highest priority in the prioritized row.

Entry: Nothing
Output: The data that has the highest priority within the prioritized row
Precondition: That the prioritized row contains at least 1 data.
Postcondition: Nothing

empty

Description: Returns a boolean value saying if the prioritized row is empty or has data.

Entry:Nothing
Output: A boolean value that tells whether the prioritized row is empty or has data.
Precondition: Nothing.
Postcondition: Nothing

size

Description: Returns the amount of data that the prioritized row has

Entry :Nothing
Output :An integer value representing the amount of data in the prioritized row
Precondition: Nothing.
Postcondition: Nothing

It has to include the next class header(obligatory):

#ifndef MYHEAP_H

#define MYHEAP_H

class   MyHeap{

    private:

        int* values; //where the HEAP values ​​are going to be saved

        int size; //Represents how many values ​​the Heap has stored  

    public:

        MyHeap(); //Initialize the attributes. The values ​​attribute initializes it as an empty array size 7

        void push(int n); // Insert a value in the heap. Only when the new value does not fit in the array
// grow the array to size 2 * n + 1. (Dynamic expansion of the array)
// That is, if you already have the arrangement with 7 values ​​and you want to insert another value (The 8th)
// then the array is grown to size 15, the first 7 values ​​of the original array are copied
// and the 8th value is inserted.

        void pop(); //A value is removed from the heap. It is never necessary to decrease the size of the array.

        int top(); //Return who is the next element to exit but without deleting it

        bool isEmpty(); //returns true if the heap is empty otherwise returns false

        int length(); //returns how many elements the heap is storing

    };

#endif

In this lab, I want you to take in a numeric grade as an integer and then print a letter grade per the table below:

90 or above is an A

80 or above is a B

70 or above is a C

60 or above is a D

Below a 60 is an F

You must use a branching statement that prints the appropriate letter grade based on the user input2. Please comment your code
