Based on your observation and group discussion, explain the evolution of data storage based on the following category: 1. Physical element (size/weight, portability, durability) 2. Non-physical element (cost, accessibility)

USING C#

Design and implement a program (name it SumValue) that reads three integers (say X, Y, and Z) and prints out their values on separate lines with proper labels, followed by their average with proper label. Comment your code properly.Format the outputs following the sample runs below.

Sample run 1:

X = 7

Y = 8

Z = 10

Average = 8.333333333333334

how to write a cpp program that takes a number from a user, and print the sum of all numbers from one to that number on screen? using loop interation as basic as possible.

Part A

In PyCharm, write a program that prompts the user for their name and age. Your program should then tell the user the year they were born. Here is a sample execution of the program with the user input in bold:

What is your name? Amanda
How old are you? 15

Hello Amanda! You were born in 2005.

1. Write the program. Format your code using best practices. Refer to the zyBooks style guide, if needed, to use proper naming conventions for variables and methods. Use the most appropriate statements with minimal extraneous elements, steps, or procedures.
2. Run the program.
3. Debug the program. Be sure your code produces the correct results.
4. Save and submit your file.

Part B

While you don’t need an IDE to write a program, there are some features that make it desirable. What did you notice when using PyCharm to develop a simple program? For instance, you might have noticed how color is used. Identify two to three features that could make coding easier for programmers, and briefly explain why.

How to generate a key pair for Alice and Bob Respectively Suppose Alice sends plaintext P= 113, how does she encrypt and whats the ciphertext C? After Bob receives C, how does he decrypts it to get the plaintext P? Suppose Alice sends plaintext P= 113, how does she sign it and what are sent to Bob. How does Bob verify the signature? Suppose Bob sends plaintext P=113, how does he sign it and what are sent Alice. How does Alice verify the signature?

1. Examine the structures of the DEPARTMENT and ASSET tables:

   DEPARTMENT
   -------------------------
   DEPT_ID NUMBER(9) NOT NULL
   DEPT_ABBR VARCHAR2(4)
   DEPT_NAME VARCHAR2(25) NOT NULL
   MGR_ID NUMBER
   
   ASSET
   -----------
   ASSET_ID NUMBER(9) NOT NULL
   ASSET_VALUE FLOAT
   ASSET_DESCRIPTION VARCHAR2(25)
   DEPT_ID NUMBER(9)
   
   The DEPT_ID column of the ASSET table has a FOREIGN KEY constraint referencing the DEPARTMENT table. You attempt to update the ASSET table using 
   this statement:

   UPDATE asset

   SET dept_id =(SELECT dept_id
   FROM department
   WHERE dept_name =(SELECT dept_name
   FROM department
   WHERE dept_abbr = 'FINC')),
   asset_value = 10000
   WHERE asset_id = 2;
   
   Which two statements must be true for this UPDATE statement to execute without generating an error? (Choose two.)

   	A.	An asset with an ASSET_ID value of 2 must exist in the ASSET table.
   	B.	Only one row in the DEPARTMENT table can have a DEPT_ABBR value of FINC.
   	C.	One of the subqueries should be removed because subqueries cannot be nested.
   	D.	Both of the subqueries used in the UPDATE statement must return one and only one non-null value.
   	E.	Only one row in the DEPARTMENT table can have the same DEPT_NAME value as the department with DEPT_ABBR of FINC.

USE JAVA. Write a very general sort method that can sort any type of data arrays/lists. For example, can sort a list of integers in ascending order, a list of integers in descending order, a list of doubles, a list of student objects (with names and scores) in ascending order of names, or in descending order of scores, … You can use any pre-defined sort function or can code your own. Use your favorite language for implementation. If your language doesn’t support these features, implement a revised version (clearly state the revision you made to the problem with a brief discussion of the language’s weakness.) Then test the following cases: (a) 4, 3, 7, 2, 1, 9 in ascending order (b) 4.5, 2.0, 9.0, 8.4, 7.2, 6.1, 20.5, 2.1 in descending order (c) John 40, Casey 45, Ben 47, Zadi 41, Kay 39, Tay 43 in ascending order of names (d) John 40, Casey 45, Ben 47, Zadi 41, Kay 39, Tay 43 in descending order of scores Include your program source code and test cases (may copy paste output or show screenshots) as answer to any coding problem. Use Java.

Draw parse trees for nine strings in question one, using their grammars.

1. For the following grammars, write the leftmost derivation for the strings given with each. Next to each derivation step, write the number of the rule used. Do not combine steps.  
   1. grammar (3 rules), Σ = {a, b}:

S -> aSbS | bSaS | ε

strings (3): ab, baab, bbaa

2. grammar (6 rules), Σ = {0, 1}:

S -> A1B

A -> 0A | ε

B -> 0B | 1B | ε

strings (3): 1, 0011, 01010

3. grammar (6 rules), Σ = { +, x, a, (, ) }

E -> E + T | T

T -> T x F | F

F -> (E) | a

strings (3): a, a x a, (a) + a x a,

4. grammar (4 rules), Σ = {(, ), [, ]}:

S -> (S) | [S] | SS | ε

strings (3): ( ), [ ] ( ), ( [ ] )  

Using Packet Tracer Create a Network for 3 departments (sales, accounting, HR) in a business.

This network should observe reduced collisions and minimum broadcasts.

Use private network addressing to simulate the network.

PLEASE PROVIDE The network diagram, and pings/simulations to demonstrate the correct functioning of the network. I will rate.

Please use your own Wire-Shark tool and answer the following questions. If possible please mention the steps or pictures on how the questions were answered.

1. What is the MAC address of the server?

2. What is the MAC address of the client?

3. What version of the web server is the server running?

4. Which web browser and what version is the client running?

5. Which cipher suites are supported by the client?

6. Which cipher suite does the server agree upon?

7. How many bytes were able to be decrypted? (Use Follow SSL stream to find out)

8. What is in the "<head>" tag of the client GET request of the client?

9. What port is used by the client to communicate with HTTPS on the server?

10. What is the version of OpenSSL running on the server?

Write a program that allows the user to navigate the lines of text in a file. The program should prompt the user for a filename and input the lines of text into a list. The program then enters a loop in which it prints the number of lines in the file and prompts the user for a line number. Actual line numbers range from 1 to the number of lines in the file. If the input is 0, the program quits. Otherwise, the program prints the line associated with that number.

An example file and the program input and output is shown below:

example.txt

Line 1.
Line 2.
Line 3.

Enter the input file name: example.txt

The file has 3 lines.
Enter a line number [0 to quit]: 2
2 :  Line 2.
The file has 3 lines.
Enter a line number [0 to quit]: 4
ERROR: line number must be less than 3.
The file has 3 lines.
Enter a line number [0 to quit]: 0

Make sure the program gracefully handles a user entering a line number that is too high.

Garden Glory Project Questions Assume that Garden Glory designs a database with the following tables:

OWNER (OwnerID, OwnerName, OwnerEmail, OwnerType)

OWNED_PROPERTY (PropertyID, PropertyName, PropertyType, Street, City, State, Zip, OwnerID)

GG_SERVICE (ServiceID, ServiceDescription, CostPerHour);

EMPLOYEE (EmployeeID, LastName, FirstName, CellPhone, ExperienceLevel)

PROPERTY_SERVICE ( PropertyServiceID , PropertyID , ServiceID, ServiceDate , EmployeeID, HoursWorked)

The referential integrity constraints are:

OwnerID in OWNED_PROPERTY must exist in OwnerID in OWNER

PropertyID in PROPERTY_SERVICE must exist in PropertyID in OWNED_PROPERTY

ServiceID in PROPERTY_SERVICE must exist in ServiceID in GG_SERVICE

EmployeeID in PROPERTY_SERVICE must exist in EmployeeID in EMPLOYEE

Assume that OwnerID in OWNER, PropertyID in PROPERTY, and EmployeeID in EMPLOYEE are surrogate keys with values as follows:

OwnerID Start at 1 Increment by 1

PropertyID Start at 1 Increment by 1

ServiceID Start at 1 Increment by 1

EmployeeID Start at 1 Increment by 1

PropertyServiceID Start at 1 Increment by 1

Code in c#

Write a recursive method called isReverse(String s1, String s2) that accepts two strings as parameters and returns true if the two strings contain the same sequence of characters as each other but in the opposite order and false otherwise. • The recursive function should ignore capitalization. (For example, the call of isReverse("hello", "eLLoH") would return true.) • The empty string, as well as any one letter string, should be its own reverse. Write a driver program that calls this method from the Main program.

Program should ask for user input and reverse the sequence of characters.
