Answer and Explanation:
Deadlock occurs when two operating systems on the same computer are hindering each other's execution, getting blocked, waiting for each one to run first. This can happen when a preemption has not occurred, when a mutual exclusion has occurred, or when one of the systems causes the other to not execute.
File manager is software that allows a computer user to create directories and organize files inside and outside of them.
Process is the term used to determine the functioning of computer software. When a software is started, it uses its own programming code to perform a specific activity.
Multiprogramming is the term used for the moment when an operating system allows the user to run more than one software at the same time. For this to happen, the computer needs to have a high processing capacity, to handle the effort of running several software simultaneously.
Software Classification is the process that determines the composition and different aspects that make up a software. In this way, it is possible to understand the usefulness and programming of this software.
Virtual memory is the use of secondary memory for caching. This allows the user to share files more securely and quickly, in addition to alleviating the problems that limited memory presents.

Write a Java program that creates a two-dimensional array of type integer of size x by y (x and y must be entered by the user). The program must fill the array with random numbers from 1 to 9. Then, the program must print the original array and the elements that are in even columns of the array.
Answer:
The java program is as follows:
import java.util.*;
public class Main{
public static void main(String[] args) {
Scanner input = new Scanner(System.in);
Random r = new Random();
int x, y;
x = input.nextInt();
y = input.nextInt();
int[][] Array2D = new int[x][y];
for(int i = 0; i < x ; i++){
for(int j = 0; j < y; j++){ Array2D[i][j] = r.nextInt(9) + 1; }
}
for(int i = 0; i < x ; i++){
for(int j = 0; j < y; j++){ System.out.print(Array2D[i][j]+" "); }
System.out.println();
}
for(int i = 0; i < x ; i++){
for(int j = 1; j < y; j+=2){ System.out.print(Array2D[i][j]+" "); }
System.out.println();
}
}
}
Explanation:
This creates a random object
Random r = new Random();
This declares x and y as integers
int x, y;
This gets input for x
x = input.nextInt();
This gets input for y
y = input.nextInt();
This declares the 2D array
int[][] Array2D = new int[x][y];
The following iteration populates the array with integers 1 to 9
for(int i = 0; i < x ; i++){
for(int j = 0; j < y; j++){ Array2D[i][j] = r.nextInt(9) + 1; }
}
The following iteration prints all elements of the array
for(int i = 0; i < x ; i++){
for(int j = 0; j < y; j++){ System.out.print(Array2D[i][j]+" "); }
System.out.println();
}
The following iteration prints all elements on the even column
for(int i = 0; i < x ; i++){
for(int j = 1; j < y; j+=2){ System.out.print(Array2D[i][j]+" "); }
System.out.println();

A constructor can be overloaded with more than one function which has the same name but with what two different things
i. Number of parameters
ii. Type of parameters
Explanation:When there are two or more constructors, definitely with the same name, in a given class, then the constructors are said to be overloaded. An overloaded constructor appears declared many times in a class but each time with different number of parameters and/or type of parameters.
For example, given a class Test, the following combination of constructors can exist;
i. public Test(int x){
}
ii. public Test(String m){
}
iii. public Test(int a, String b){
}
The following should be noted;
In the case of combination (i) and (ii), the constructors have the same number of parameters but different type of parameter. In other words, they both have 1 parameter but while the first one has a parameter type of int, the second has a parameter type of String.
In the case of combination (ii) and (iii), the constructors have different number of parameters and of course different type of parameters. In other words, the second constructor has 1 parameter of type String while the third constructor has 2 parameters of types int and String.
What does Falstaff do to protect himself in battle?
Write a program that lets the user enter the total rainfall for each of 12 months into an array of doubles. The program should calculate and display the total rainfall for the year and the average monthly rainfall. Use bubble sort and sort the months with the lowest to highest rain amounts. Use the binary search and search for a specific rain amount. If the rain amount is found, display a message showing which month had that rain amount. Input Validation: Do not accept negative numbers for monthly rainfall figures.

Christina has been asked by the firewall administration group to identify secure network protocols that can be used to prevent network analyzers from being able to read data in flight. What are considered as secure network protocols?
Answer:
SSH, HTTPS and SMTP
Explanation:
Data theft can be defined as a cyber attack which typically involves an unauthorized access to a user's data with the sole intention to use for fraudulent purposes or illegal operations. There are several methods used by cyber criminals or hackers to obtain user data and these includes DDOS attack, SQL injection, man in the middle, phishing, etc.
Encryption is a form of cryptography and typically involves the process of converting or encoding informations in plaintext into a code, known as a ciphertext. Once, an information or data has been encrypted it can only be accessed and deciphered by an authorized user.
Some examples of encryption algorithms are 3DES, AES, RC4, RC5, and RSA.
Hence, SSH, HTTPS and SMTP are considered as secure network protocols.
HTTPS is acronym for Hypertext Transfer Protocol Secure while SSL is acronym for Secure Sockets Layer (SSL).
SMTP is an acronym for Simple Mail Transfer Protocol and it uses the standard port number of 25 to provide clients with requested services.

Given the value x=false ,y=5 and z=1 what will be the value of F=(4%2)+2*Y +6/2 +(z&&x)?
F = 13
Explanation:Given:
x = false
y = 5
z = 1
F = (4%2)+2*Y +6/2 +(z&&x)
We solve this arithmetic using the order of precedence:
i. Solve the brackets first
=> (4 % 2)
This means 4 modulus 2. This is the result of the remainder when 4 is divided by 2. Since there is no remainder when 4 is divided by 2, then
4 % 2 = 0
=> (z && x)
This means (1 && false). This is the result of using the AND operator. Remember that && means AND operator. This will return false (or 0) if one or both operands are false. It will return true (or 1) if both operands are true.
In this case since the right operand is a false, the result will be 0. i.e
(z && x) = (1 && false) = 0
ii. Solve either the multiplication or division next whichever one comes first.
=> 2 * y
This means the product of 2 and y ( = 5). This will give;
2 * y = 2 * 5 = 10
=> 6 / 2
This means the quotient of 6 and 2. This will give;
6 / 2 = 3
iii. Now solve the addition by first substituting the values calculated earlier back into F.
F = (4%2)+2*Y +6/2 +(z&&x)
F = 0 + 10 + 3 + 0
F = 13
Therefore, the value of F is 13

The compound known as butylated hydroxytoluene, abbreviated as BHT, contains carbon, hydrogen, and oxygen. A 1.501 g sample of BHT was combusted in an oxygen rich environment to produce 4.497 g of CO2(g) and 1.473 g of H2O(g). Insert subscripts below to appropriately display the empirical formula of BHT.
Answer:
C15H24O
Explanation:
n(C) = 4.497 g/44g/mol = 0.1022
Mass of C = 0.1022 × 12 = 1.226 g
n(H) = 1.473g/18 g/mol = 0.0823 ×2 moles = 0.165 moles
Mass of H = 0.0823 × 2 ×1 = 0.165g
Mass of O= 1.501 -(1.226 + 0.165)
Mass of O= 0.11 g
Number of moles of O = 0.11g/16g/mol = 0.0069 moles
Dividing through by the lowest ratio;
0.1022/0.0069, 0.165/0.0069, 0.0069/0.0069
