Write a Java application with a main() to find the two largest distinct integers entered on the command line by the user. We are just creating a simple stand-alone application. All your code can be in main().
Answers
Answer:
import java.util.Scanner; // Scanner class is to use input output functions
public class TwoDistinctLargest //class to find two distinct largest nos
{
public static void main(String[] args) { //start of main() function
Scanner input = new Scanner(System.in); // creates Scanner type object
int integers = 0, largest1 = 0, largest2 = 0; // declare variables
/* integers holds the input integer values, largest1 has 1st largest number and largest 2 contains second distinct largest number, i is used as the count variable to move through the input integers */
int i = 0;
//prompts user to enter integers and enter 0 to stop
System.out.println("Enter the integers (press 0 to stop): ");
integers = input.nextInt(); //reads and scans input integers
while(integers != 0) {
/* the loop keeps taking integer values from user until the value of integers is equal to 0, this means until the user enters 0 */
//checks if the value of integer is greater than first largest computed number
if(integers > largest1) {
//if the value in largest1 is greater than that of largest2
if(largest1 > largest2) {
largest2 = largest1; } // then value of largest1 is set to largest2
largest1 = integers; // largest1 now holds the value of integers //which means largest1 holds the first distinct largest integer
} else { //checks if the value of integers is greater than largest2
if(integers > largest2) {
//if the value of integers is not equal to that of largest1
if(integers!=largest1) {
// set the value of second distinct largest number to largest2
largest2 = integers;} } }
i++; //keeps moving to the next input integer
integers = input.nextInt(); //keeps taking input integers }
//prints the two distinct largest integers
System.out.println("\n The 1st largest distinct integer is " + largest1);
System.out.println("\n The 2nd largest distinct integer is " + largest2); } }
Explanation:
Lets suppose the user inputs the following integers
1, 6, 5, 6, 0
Initial values are:
integers = 0
largest1 = 0
largest2 = 0
i = 0
When the user enters 1, then value of integers = 1
while loop checks if integers!=0. As integers =1 so the program enters the body of while loop. The first IF condition is checked if(integers > largest1)
As largest1 = 0 and integers =1 so this condition evaluates to true as 1 > 0
So the statements in the body of this IF condition are executed. This if conditions contains another if statement if(largest1 > largest2) which checks if the value largest1 is greater than that of largest2. Its false because largest1 =0 and largest2 =0 so largest1 = largest2, so the statement of this if condition body will not execute and program moves to this largest1 = integers; statement which sets the value of integers i.e. 1 to largest1. So the value of largest1 = 1
Now the i is incremented by 1 and it points at second value of integers= 6.
while loop checks if integers!=0. As integers =6 so the program enters the body of while loop. The first IF condition is checked if(integers > largest1)
As largest1 = 1 and integers =6 so this condition evaluates to true as 6>1
So the statements in the body of this IF condition are executed. This if conditions contains another if statement if(largest1 > largest2) which checks if the value largest1 is greater than that of largest2.
Its true because largest1 =1 and largest2 =0 so largest1 > largest2, so the next statement is executed largest2 = largest1; So now the value of largest2=1.
Now program moves to this largest1 = integers; statement which sets the value of integers i.e. 6 to largest1. So the value of largest1 = 6
Now the i is incremented by 1 and it points at second value of integers= 5.
while loop condition is again true. IF condition is checked if(integers > largest1)
As largest1 = 6 and integers =5 so this condition evaluates to false as 5<6. So this IF part will not execute and program control moves to the else part.
Else part has an if condition if(integers > largest2) which evaluates to true because integers = 5 and largest2 = 1 so the program moves to next if statement inside the previous if statement of else part i.e. if(integers!=largest1). This if statement is the main statement which will help in finding two distinct largest numbers in case the same largest value is input more than once. It checks If the value of integers is not equal to largest1 value. As integers = 5 and largest1 = 6 so this if condition is true. If this condition is not used in this program then largest2 will not be assigned distinct largest values but assigned 6 for both largest1 and largest2 as 6 is input twice. Next this if statement largest2 = integers assigns value of integers to largest2 which is the second largest distinct integer.
Now the i is incremented by 1 integers value become 0.
while loop checks if integers!=0. As integers =0 so the while loop breaks. The last two print statements which produce following output.
The 1st largest distinct integer is: 6
The 2nd largest distinct integer is: 5

Answers
Answer:
I am writing a Python program:
def string_type(string):
if string=="": //if the string is empty
return "empty"
elif string.count(".")>1: #if the period sign occurs more than once in string
if string.count("\n"): #checks if the new line occurs in the string
return "page" #if both the above cases are true then its a page
return "paragraph" # if the period sign condition is true then its a para
elif string.count(" ")>=1: #if no of spaces in string occur more than once
return "sentence" #returns sentence
elif len(string)==1: # if length of the string is 1 this
return "character" #returns character
else: #if none of the above conditions is true then its a word
return "word" #returns word
Explanation:
def string_type(string): this is the definition of method string_type which takes a string as argument and determines whether the type of string is a word, paragraph, page, sentence or empty.
if string=="" this if condition checks if the string is empty. If this condition is true then the method returns "empty"
elif string.count(".")>1 This condition checks if the string type is a paragragh
string.count(".")>1 and if string.count("\n") both statements check if the string type is a page.
Here the count() method is used which is used to return the number of times a specified string or character appears in the given string.
Suppose the string is "Paragraphs need to have multiple sentences. It's true.\n However, two is enough. Yes, two sentences can make a paragraph."
The if condition first checks if count(".")>1 which means it counts the occurrence of period i.e. "." in the string. If the period occurs more than once this means it could be a page. But it could also be a paragraph so in order to determine the correct string type another if statement if string.count("\n") inside elif statement determines if the string is a page or not. This statement checks the number of times a new line appears in the string. So this distinguishes the string type paragraph from string type page.
elif string.count(" ")>=1: statement determines if the string is a sentence. For example if the string is "i love to eat apples." count() method counts the number of times " " space appears in the string. If the space appears more than once this means this cannot be a single word or a character and it has more than one words. So this means its a sentence.
elif len(string)==1: this else if condition checks the length of the string. If the length of the string is 1 this means the string only has a single character. Suppose string is "!" Then the len (string) = 1 as it only contains exclamation mark character. So the method returns "character" . If none of the above if and elif conditions evaluates to true then this means the string type is a word.
Answer:
def string_type(string):
if string=="": //if the string is empty
return "empty"
elif string.count(".")>1: #if the period sign occurs more than once in string
if string.count("\n"): #checks if the new line occurs in the string
return "page" #if both the above cases are true then its a page
return "paragraph" # if the period sign condition is true then its a para
elif string.count(" ")>=1: #if no of spaces in string occur more than once
return "sentence" #returns sentence

Explain what a honeypot is. In your explanation, give at least one advantage and one disadvantage of deploying a honeypot on a corporate network.
Answers
Answer:
A honeypot is a computer network set up to act as a decoy to track, deflect, or research trying to obtain unwanted access to the information system.
Explanation:
A honeypot is a device or device network designed to imitate possible cyber-attack targets. It can be utilized to detect or deflect assaults from a legitimate military target. It may also be used to collect knowledge on how cybercrime works.
Advantage:-
Data Value:- One of the challenges faced by the research community is to obtain meaning from big data. Companies hold large quantities of data daily including firewall logs, device logs, and warnings for vulnerability scanning. Resources:- The problem facing most protection systems is resource shortages or even the depletion of resources. Power saturation is when a protection asset can no longer work since it is overloaded by its assets. Simplicity :- I find simplicity to be the biggest single strength of honeypots. No flashy techniques are to be created, no stamp computer systems to be managed, no rule units to be misconfigured.Disadvantage:-
That honeypot doesn't replace any safety mechanisms; they just operate with your overall security infrastructure and improve it.

Write a program that asks the user to input a positive integer and then calculates and displays the factorial of the number. The program should call a function named getN
Answers
Answer:
The program is written in python and it doesn't make use of any comment;
(See explanation section for line by line explanation)
def getN(num):
fact = 1
for i in range(1, 1 + num):
fact = fact * i
print("Factorial: ",fact)
num = int(input("Number: "))
if num < 0:
print("Invalid")
else:
getN(num)
Explanation:
The function getNum is defined here
def getN(num):
Initialize the result of the factorial to 1
fact = 1
Get an iteration from 1 to the user input number
for i in range(1, 1 + num):
Multiply each number that makes the iteration
fact = fact * i
Print result
print("Factorial: ",fact)
Ths line prompts user to input number
num = int(input("Number: "))
This line checks if user input is less than 0; If yes, the program prints "Invalid"
if num < 0:
print("Invalid")
If otherwise, the program calls the getN function
else:

Because Java byte code is the same on all computers, compiled Java programs Group of answer choices Cannot run on Linux systems Must be re-compiled for each different machine it is run on Are highly portable Are non-existent
Answers
Answer:
Are highly portable.
Explanation:
Java is a object oriented and class-based programming language. It was developed by Sun Microsystems on the 23rd of May, 1995.
Java was designed by a software engineer called James Gosling and it is originally owned by Oracle. Also, worthy of mention is the fact that Java was originally known as Oak.
Generally, Java as a software application usually are developed having a ".jar", ".class" or ".java" filename extensions.
Because Java byte code is the same on all computers, compiled Java programs are highly portable. This simply means that, the Java byte code was designed such that it has very few implementation dependency, thus, once the code is written, it can run on all computer platforms that supports the Java programming language.
Hence, the Java byte code is a write once, run anywhere software program.
The Java byte code instructions are read and executed by a computer program known as a Java Virtual Machine (JVM).
Additionally, Java program is used for developing varieties of applications such as, mobile, desktop, games, web and application servers etc.
It is always possible and feasible for a programmer to come up with test cases that run through every possible path in a program.
A. True
B. False
Answers
Answer:
True
Explanation:
It is always possible and feasible for a programmer to come up with test cases that run through every possible path in a program is a "true statement" or the first option. It is very natural for a programmer/developer to come up with test that will run through every possible outcome in a program. Doing so will help the developer find things that might cause problems with the program in later time.
Hope this helps.
The answer to the question about the feasibility of a programmer to always come up with test cases that run through every possible path in a program is:
NoWhat is a Test Case?This refers to the set of actions which a programmer performs to find out if his software or program passes the system requirements in order to work properly.
With this in mind, we can see that while in some cases, it is possible for the programmer to come up with test cases, but it is not feasible in all cases as there can be hardware error which a virtual machine cannot solve.

A network technician is designing a network for a small company. The network technician needs to implement an email server and web server that will be accessed by both internal employees and external customers. Which of the following would best secure the internal network and allow access to the needed servers?
A. Implementing a site-to-site VPN for server access.B. Implementing a DMZ segment for the server.C. Implementing NAT addressing for the servers.D. Implementing a sandbox to contain the servers.
Answers
Answer:
Option A (Implementing a site-to-site VPN for server access) seems to be the correct choice.
Explanation:
A site-to-site configuration is something that a single Open VPN network links several more separate networks linked. Technologies through one network will access machines in all the other computer systems in that connection model, including conversely. Implementing this would be extremely straightforward, for as much further even though Access Server was indeed implicated.The much more challenging aspect happens when interacting regarding firewalls including privacy filtering methods, as well as modifying the forwarding table in internet gateways, as several of them from different manufacturers but instead prototypes which they may not be able to log many of these.This rather gateway device uses an Open VPN with a Linux VPN client, to create a connection between various channels. If someone's server hardware is also measured accurately then perhaps a site-to-site configuration could be accomplished which works straightforwardly throughout all systems in both cable systems.Other choices are not related to the given instance. So that Option A would be the right one.

Answers
Answer:
a. Compile code
Explanation:
In programming process, the following are important in defining what a program is to do;
i. Purpose: The first step in writing a program is describing the purpose of the program. This includes the aim, objective and the scope of the program. The purpose of a program should be defined in the program.
ii. Input: It is also important to specify inputs for your program. Inputs are basically data supplied to the program in order to perform a task. Valid inputs are defined in the program.
iii. Output: Many times, when inputs are supplied to a program the resulting effects are shown in the outputs. The way the output will be is defined in the program.
iv. Process: This involves the method by which inputs are being mapped into outputs. The process implements the functionality of the program by converting inputs into their corresponding outputs. The process is defined in the program.
Compile code is not a requirement in defining what a program is to do. It just allows the source code of the program to be converted into a language that the machine understands.

a. A hard disk has four surfaces (that's top and bottom of two platters). Each track has 2, 048 sectors and there are 131, 072 (2^17) tracks per surface. A block holds 512 bytes. The disk is not "zoned." What is the total capacity of this disk?
b. Given the disk in Part 1, how much data can be accessed without moving the disk heads. (That, is, what is the capacity of one cylinder?)
Answers
Answer:
Explanation:
Given that:
number of surfaces on a hard disk = 4
number of sectors = 2048 sectors
number of tracks per surface = 131, 072 (2^17)
a block holds 512 bytes.
Since, 'The disk is not "zoned.".....
then, Number of bytes / sector = 512
a) What is the total capacity of this disk?
The total capacity of the disk is:[tex]= 4 \ surfaces \times 131072 \dfrac{tracks}{surfaces} \times 2048 \dfrac{sector}{tracks} \times 512 \dfrac{bytes}{sector}[/tex]
[tex]= 5.49755814\times 10^{11} \ bytes[/tex]
= 549755814 KB ( kilobytes)
= 549755.814 MB (megabytes)
=549.755814 GB (gigabytes)
b. Given the disk in Part 1, how much data can be accessed without moving the disk heads. (i.e what is the capacity of one cylinder?)
The capacity of one cylinder can be estimated by determining the capacity of one surface and the capacity of one track.
The capacity of one surface = [tex]131072\dfrac{tracks}{surface} \times 2048 \dfrac{sector}{tracks} \times 512\dfrac{bytes}{sector}[/tex]
The capacity of one surface = [tex]1.37438953 \times 10^{11[/tex] byte = 137.44 GB
Capacity of one track = 2048 sectors/track × 512 bytes/sector
Capacity of one track = 1048576 Bytes/track
Capacity of one track =1048 KB/track
Capacity of one track ≅ 1 MB/track
Since the hard disk contains four surfaces
∴
capacity of one cylinder = 1 MB/track × 4 track/cylinder
capacity of one cylinder = 4 MB

print('FIXME: Finish compute_avg()')
return -1
Explanation:
A stub is a small function or a piece of code which is sometimes used in program to test a function before its fully implemented. It can also be used for a longer program that is to be loaded later. It is also used for a long function or program that is remotely located. It is used to test or simulate the functionality of the program.
The first stub for the function get_user_num() displays FIXME: Finish get_user_num() and then it returns -1.
The seconds stub for the function compute_avg() displays the FIXME: Finish compute_avg() and then it returns -1.
Here with each print statement, there is function name after this FIXME: Finish line. The first function name is get_user_num and the second is compute_avg().
Next the function get_user_num() is called twice and function compute_avg() followed by a print statement: print('Avg:', avg_result) which prints the result. So the program as a whole is given below:
def get_user_num():
print('FIXME: Finish get_user_num()')
return -1
def compute_avg(user_num1, user_num2):
print('FIXME: Finish compute_avg()')
return -1
user_num1 = 0 # the variables are initialized to 0
user_num2 = 0
avg_result = 0
user_num1 = get_user_num() #calls get_user_num method
user_num2 = get_user_num()
avg_result = compute_avg(user_num1, user_num2)
print('Avg:', avg_result)
The method get_user_num() is called twice so the line FIXME: Finish get_user_num() is printed twice on the output screen. The method compute_avg() is called once in this statement avg_result = compute_avg(user_num1, user_num2) so the line FIXME: Finish compute_avg() is printed once on the output screen. Next the statement print('Avg:', avg_result) displays Avg: -1. You can see in the above program that avg_result = compute_avg(user_num1, user_num2) and compute_avg function returns -1 so Avg= -1. The program along with the produced outcome is attached.
Assume that to_the_power_of is a function that expects two integer parameters and returns the value of the first parameter raised to the power of the second parameter. Write a statement that calls to_the_power_of to compute the value of cube_side raised to the power of 3 and that associates this value with cube_volume.
Answers
Answer:
The statement in python is as follows:
to_the_power_of(cube_side,3)
Explanation:
As stated as the requirement of the code segment, the statement takes as parameters a variable cube_side and a constant 3.
It then returns the volume of the cube; i.e. cube raise to power 3
See full program below
def to_the_power_of(val,powe):
result = val**powe
print(result)
cube_side = float(input("Cube side: "))
to_the_power_of(cube_side,3)
The UNIX operating system started the concept of socket which also came with a set of programming application programming interface (API) for 'socket level' programming. A socket was also uniquely identified:
a. as the combination of IP address and port number to allow an application within a computer to set up a connection with another application in another computer without ambiguity.
b. the port number to clearly identify which application is using TCP.
c. IP address to make sure the Internet device using the socket is delineated.
d. the access network, such as Ethernet or Wi-Fi so that multiple LAN devices could be installed on a single computer.

In the context of structured systems analysis and design (SSAD) models, a _____ is a tool that illustrates the logical steps in a process but does not show data elements and associations.
Answers
Answer:
Flowchart.
Explanation:
Structured Systems Analysis and Design (SSAD) is a methodology and a systems technique of analyzing and designing of information systems.
This system uses several tools to design various components such as dataflow diagram, conceptual data model, flowchart, etc.
In the given scenario, the tool that will be used by the system would be a flowchart.
A flowchart is a diagram that represents a systematic flow of a process. In SSAD, flowchart is used to illustrate the logical steps to be taken in a process but it does not show data elements and associations.
So, the correct answer is flowchart.
Shovels and Shingles is a small construction company consisting of 12 computers that have Internet access. The company's biggest concern is that a wily competitor will send e-mail messages pretending to be from Shovels and Shingles in order to get confidential information. Write down an encryption solution that best prevents a competitor from receiving confidential information and justify the recommendation.
Answers
Answer:
The Encryption solution that best prevents a competitor from receiving confidential information is the SSL(secure Socket Layer) Or TLS(Transport Layer Security).
Explanation:
Solution:
From my own perspective the encryption solution that i will use that prevents s a competitor from receiving confidential information and justify the recommendation is the SSL(secure Socket Layer) Or TLS(Transport Layer Security).
This is because in this case we have to share data confidentially (information need to be hidden from Unauthorized security access. also these provides the Transport Layer security that we needed in above example above.
The purpose of these protocol is to provide server and client authentication, Data confidentiality,and Data integrity (protected from unauthorized change). Application Layer client/server program such as HTTP that uses the service of TCP can encapsulate their data in SSL Packets.
SSL (Secure Socket Layer): is defined as the normal technology for protecting an internet connection secure and defend any sensitive data that is being sent between two systems, and not allowing criminals from reading and changing any information sent, including potential personal details.
TLS (Transport Layer security): It is a procedure that allows data integrity and privacy over Internet communications.
