Question options:

The data communication process is described by the following:

Question options:

1. A company that wants to send data over the Internet will use an encryption program to ensure data security. All data will be transmitted as four-digit integers. The application should read a four-digit integer entered by the user and encrypt it as follows:  Replace each digit with the remainder of the new value divided by 10 by adding 6 to the digit. Then replace the number in the first digit with the third, and the number in the second digit with the fourth. Print the encrypted integer on the screen.  Write a separate application where an encrypted four-digit integer is entered and decrypted (reversing the encryption scheme) and finds the original number. 2. Create a class called Employee that contains three instance variables (First Name (String), Last Name (String), Monthly Salary (double)). Create a constructor that initializes these variables. Define set and get methods for each variable. If the monthly salary is not positive, do not set the salary. Create a separate test class called EmployeeTest that will use the Employee class. By running this class, create two employees (Employee object) and print the annual salary of each employee (object). Then set the new salary by giving each employee a 10% raise and display each employee's annual salary on the screen again.

Note: code should be written in Java language.

Explain how the software can influence positively on business strategies and what are the main software required in any organization with an example?

In the decimal system (base 10), a natural number is represented as a sequence dndn−1 . . . d0 of (decimal) digits, each of which is in the range 0..9. The value of the number is d0 ×100 +d1 ×101 +···+ dn ×10n. Similarly, in the binary system (base 2), a natural number is represented as a sequence bnbn−1 · · · b0 of (binary) digits, each of which is 0 or 1. The value of the number is b0 ×20 +b1 ×21 +···+bn ×2n. For example, the value of the number whose binary representation is 101is: 1×20+0×21+1×22 =1+0+4=5.

Without using any built-in functions for converting numbers, write a function that takes as input the binary representation of a positive integer n and returns its decimal representation.

Write a program that repeatedly asks the user to enter their password until they enter the correct one. However, after 5 failed attempts, the program "locks out" the user. We will show that with an error message.
Assume the password is HOC2141 (case sensitive).
Note that there is a special case that is not shown below. To identify it, think of all possible scenarios of input for this program.

----------- Sample run 1:
Enter your password: Blake
Wrong
Enter your password: hoc2341
Wrong
Enter your password: hoc2141
Wrong
Enter your password: HOC2141
Correct! You're in!
Bye 

----------- Sample run 2:
Enter your password: HOC2141
Correct! You're in!
Bye
 
----------- Sample run 3:
Enter your password: asdf
Wrong
Enter your password: ffgdf
Wrong
Enter your password: asdxcv
Wrong
Enter your password: 1276
Wrong
Enter your password: HOCK
Wrong
You are locked out!
Bye

Write a MATLAB script which gets a matrix as input and check the dimensions of the input:

Part A) If the input matrix is a square matrix, calculate the inverse of it and show it in the command window, otherwise, show the text “the input matrix is not invertible”.

Part B) Reshape the input matrix to a row vector and assign it to Y and make a vector named X with the same length as Y then make a 2D Plot and show it.

Hi!

I have a question in Data communication and network please!

Make the “ping” return the following messages:

1_ Request Timed Out
2_Destination Network / Host unreachable
3_Time Exceeded

and explain the reasons.

I want to se result please, My computer is Mac.

Thanks!

Would your school or place of work benefit from cloud computing? Identify at least two cloud computing vendors and research their features and costs. Then, examine one element of your chosen network’s infrastructure and apply it to cloud computing. Would it be feasible to migrate to the cloud? Would it be cost effective? Why or why not?

Write a program that reads a string from the user, and creates another string with the letters from in reversed order. You should do this using string concatenation and loops. Do not use any method from Java that does the work for you. The reverse string must be built. Do not just print the letters in reversed order. Instead, concatenate them in a string.

--- Sample run:
This program will create a string with letters in reversed order.
Enter a string: banana
The reversed string is: ananab
Bye

--- Sample run:
This program will create a string with letters in reversed order.
Enter a string: what the heck
The reversed string is: kceh eht tahw
Bye

Consider the following simple script incorporating a for loop:

#!/bin/bash
RED='\033[0;31m'
NC='\033[0m'
clear; cd /home
for DIR in $HOME; do
#for DIR in *;do
CHK=$(grep -c "/home/$DIR" /etc/passwd)
if [ $CHK -ge 1 ]
then
echo -e "${NC}$DIR is good"
else
echo -e "${RED}ALERT! $DIR is NOT good!"
fi
done

What kind of script is presented above? How did you make your determination? What is the purpose of the script?

In lines #5/6, what is the type of $DIR?

In line #7, what is the value of $CHK?

In line #8, what are the instructions contained with the brackets known as?

Why are there two lines containing the word "for"? Which line will execute? Will that line execute correctly?

What should you do before running the script?

How could the script be factored into your duties as a sysadmin?
