Explain in your own words what is meant by the .NET term of "master pages"? Include an example.

Visit the web site of one of the following government agencies:

•            Federal Trade Commission

•            FFIEC

•            Federal Drug Administration

Search the site for information about the agency’s standards related to information security. Study the information you find and draw some conclusions about it. How are the regulations presented? How easily can businesses access and follow these regulations? Summarize your findings in a brief report (06 - 08 pages)

Give an example of a non-regular Context-Free Language that can be recognize by a Deterministic Pushdown automata and one that cannot.

Using C# create a new grade book program for a teacher.

We have a class with 10 students who have each taken 5 tests. Create an array to hold:

1. Each student’s name
2. Each test grade
3. The average for each student's tests

Use a random number generator to generate the test scores for each student. The student names may be hard-coded into the array.

Create and call a method that calculates and stores each student’s average in the array.

Create and call a method that displays the grades and average for each student.

C++

Modify FunctionTable.cpp so each that each function returns a string(instead of printing out a message) and so that this value is printed inside of main().

//: C03:FunctionTable.cpp
// Using an array of pointers to functions
#include <iostream>
using namespace std;
// A macro to define dummy functions:
#define DF(N) void N() { \
cout << "function " #N " called..." << endl; }
DF(a); DF(b); DF(c); DF(d); DF(e); DF(f); DF(g);
void (*func_table[])() = { a, b, c, d, e, f, g };
int main() {
while(1) {
cout << "press a key from 'a' to 'g' "
"or q to quit" << endl;
char c, cr;
cin.get(c); cin.get(cr); // second one for CR
if ( c == 'q' )
break; // ... out of while(1)
if ( c < 'a' || c > 'g' )
continue;
(*func_table[c - 'a'])();
}
}

Write a fragment of MIPS code to convert temperature in Kelvin to Fahrenheit

Static methods can be called directly from the name of the class that contains the method. Static methods are usually created to do utility operations. For example: public class Test{ public static int timesTwo(int value){ return value * value; } } public class TestDriver{ public static void main(String[] args){ int var = Test.timesTwo(5); System.out.println(var); } } Create a class called ManyLinkedLists. It will contain a static method called createLinkedList(). That method takes an argument that is a constant defined in the ManyLinkedLists class. The identifier of the constants should describe a type of linked list. When the createLinkedList method is called, it should return a linked list object of the type identified by the constant. For example: DoubleEndedList del = ManyLinkedLists.createLinkedList(ManyLinkedLists.DOUBLEENDEDLIST); Give the createLinkedList method the ability to return the linked lists described below: A double-ended linked list. A doubly linked list.

2. Combine multiple files

Use Python programming to combine two text files: customer-status.txt and sales.txt

Data columns in customer-status.txt (separated by comma):

Account Number, Name, Status 527099,Sanford and Sons,bronze

Data columns in sales.txt (separated by comma):

Account Number, Name, SKU, Quantity, Unit Price, Ext Price, Date

163416,Purdy-Kunde,S1-30248,19,65.03,1235.57,2014-03-01 16:07:40 527099,Sanford and Sons,S2-82423,3,76.21,228.63,2014-03-01 17:18:01

After you combine, you will see the following:

527099,Sanford and Sons,S2-82423,3,76.21,228.63,2014-03-01 17:18:01,bronze

Using C++

Create a polymorphic banking program using the Bank-Account hierarchy created in Exercise 2 of Written Assignment 4. For each account in the vector, allow the user to specify an amount of money to withdraw from the Bank-Account using member function debit and an amount of money to deposit into the Bank-Account using member function credit. As you process each Bank-Account, determine its type. If a Bank-Account is a Savings, calculate the amount of interest owed to the Bank-Account using member function calculateInterest, then add the interest to the account balance using member function credit. After processing an account, print the updated account balance obtained by invoking base-class member function getBalance. [MO 5.1, MO 5.2]

Write your answer in ESSAY format (approximately 300 words)

Which of the following CPUs are compatible with the Z390 AORUS MASTER Motherboard ?

AMD RYZEN 9 3900x

Intel Core i7-7700

Intel Core i7-9700k

Intel Core i9 9820x

Explain the criteria you checked to make your choice. Make sure to explain why the other CPUs were NOT compatible.

Hint: check socket type, chipset, generation, manufacturer, motherboard specifications

Describe the features of the compatible CPU including speed, cache, supported chipset and any other important features.

The explanation should be written in a way that even a layman can understand the importance of these features.
