Complete Question:
Jason has a part time job in the office of a construction company and is also a student at a community college. He often works on his homework during times when he is not busy at work because the office computer contains the software he needs to do his assignments and he hasn't been able to afford to purchase the software for his own personal computer. Which of these unacceptable uses typically included in a user access policy might he most likely be engaging in?
1.Using the network to download software for personal use
2.Disclosing personal information about employees
3.Copying of copyrighted material
4.Using a network account for a purpose not specified by the owner’s job description
Answer:
4.Using a network account for a purpose not specified by the owner’s job description
Explanation:
The office computer is meant to be used for the owner's purpose only. By using the office computer to do his homework, even at a free hour, Jason is still violating his employer's asset for selfish purpose. Jason could obtain permission from his manager to use the office computer for his homework for a temporary period, until he could "afford to purchase the software for his own personal computer." The official permission can exempt him from being penalized for the violation. A written permission is more ideal in this case.
The code below takes the list of country, country, and searches to see if it is in the dictionary gold which shows some countries who won gold during the Olympics. However, this code currently does not work. Correctly add try/except clause in the code so that it will correctly populate the list, country_gold, with either the number of golds won or the string "Did not get gold".
1
2 gold = {"US":46, "Fiji":1, "Great Britain":27, "Cuba":5, "Thailand":2, "China":26, "France":10}
3 country = ["Fiji", "Chile", "Mexico", "France", "Norway", "US"]
4 country_gold = []
5
6 for x in country:
7 country_gold.append(gold[x])
8 country_gold.append("Did not get gold")
Answer:
Modify your program by replacing
for x in country:
country_gold.append(gold[x])
country_gold.append("Did not get gold")
with
for x in country:
try:
country_gold.append(gold[x])
except:
country_gold.append("Did not get gold")
Explanation:
The addition of try/except clause in the program is to let the program manage error;
In this case, the program checks for a country in the list country; This is implemented using the following line
for x in country:
If the country exists, the statement in the try block is executed
try:
country_gold.append(gold[x]) ->This appends the country name to the country_gold list
Otherwise, the statement in the except clause is executed
except:
country_gold.append("Did not get gold") -> This appends "Did not get gold" to the country_gold list
To confirm what you've done, you may add the following line of code at the end of the program: print(country_gold)
Description:
Create a program that converts the number of miles that you walked on a hike to the number of feet that you walked.
Console:
Hike Calculator
How many miles did you walk?: 4.5
You walked 23760 feet.
Continue? (y/n): y
How many miles did you walk?: 2.5
You walked 13200 feet.
Continue? (y/n): n
Bye!
Specifications:
The program should accept a float value for the number of miles.
Store the code that gets user input and displays output in the main function.
There are 5280 feet in a mile.
Store the code that converts miles to feet in a separate function. This function should return an int value for the number of feet.
Assume that the user will enter a valid number of miles.
Answer:
The programming language is not stated (I'll answer using C++)
#include <iostream>
using namespace std;
int convert(float miles)
{
return miles * 5280;
}
int main() {
cout<<"Console:"<<endl;
cout<<"Hike Calculator"<<endl;
float miles;
char response;
cout<<"How many miles did you walk?. ";
cin>>miles;
cout<<"You walked "<<convert(miles)<<" feet"<<endl;
cout<<"Continue? (y/n): ";
cin>>response;
while(response == 'y')
{
cout<<"How many miles did you walk?. ";
cin>>miles;
cout<<"You walked "<<convert(miles)<<" feet"<<endl;
cout<<"Continue? (y/n): ";
cin>>response;
}
cout<<"Bye!";
return 0;
}
Explanation:
Here, I'll explain some difficult lines (one after the other)
The italicized represents the function that returns the number of feet
int convert(float miles)
{
return miles * 5280;
}
The main method starts here
int main() {
The next two lines gives an info about the program
cout<<"Console:"<<endl;
cout<<"Hike Calculator"<<endl;
float miles;
char response;
This line prompts user for number of miles
cout<<"How many miles did you walk?. ";
cin>>miles;
This line calls the function that converts miles to feet and prints the feet equivalent of miles
cout<<"You walked "<<convert(miles)<<" feet"<<endl;
This line prompts user for another conversion
cout<<"Continue? (y/n): ";
cin>>response;
This is an iteration that repeats its execution as long as user continue input y as response
while(response == 'y')
{
cout<<"How many miles did you walk?. ";
cin>>miles;
cout<<"You walked "<<convert(miles)<<" feet"<<endl;
cout<<"Continue? (y/n): ";
cin>>response;
}
cout<<"Bye!";

nside of your organization that checks how often client machines access it. If a client machine hasn't accessed the server in three months, the server won't allow the client machine to access its resources anymore. What can you set to make sure that your client machines and the server times are in sync
Complete Question:
Let's say that you handle the IT systems administration for your company. There's a server inside of your organization that checks how often client machines access it. If a client machine hasn't accessed the server in three months, the server won't allow the client machine to access its resources anymore. What can you set to make sure that your client machines and the server times are in sync?
Answer:
Network Time Protocol (NTP).
Explanation:
As the IT systems administrator, you can set the network time protocol (NTP) to make sure that your client machines and the server times are in synchronization.
A network time protocol (NTP) can be defined as an internet standard protocol which is used by an IT system administrator to synchronize a computer's clock to a particular time reference over packet switched or local area network (LAN) and variable-latency data networks. NTP was developed at the University of Delaware by Professor David L. Mills.
Basically, the network time protocol uses the coordinated universal time (UTC) and a client-server model to measure the total round-trip delay for a computer process.
Some network applications defer configuration until a service is needed. For example, a computer can wait until a user attempts to print a document before the software searches for available printers.
What is the chief advantage of deferred configuration?
Answer:
The drivers wont be loaded and the deamons will not be running in the background unnecessarily, that makes the processes to run more faster
Explanation:
The chief advantage of deferred configuration or the advantage when some network applications defer configuration until a service is needed is that the drivers won't be loaded and the deamons will not be running in the background unnecessarily or when idle, that makes the processes to run more faster.
Network configuration is the activity which involves setting up a network's controls, flow and operation to assist the network communication of an organization or network owner.

1. Two TCP entities communicate across a reliable network. Let the normalized time to transmit a fixed length segment equal 1. Assume that the end-to-end propagation delay is 3 and that it takes 2 to deliver data from a received segment to the transport user. The receiver initially grants a credit of 7 segments. The receiver uses a conservative flow control policy and updates its credit allocation at every opportunity. What is the maximum achievable throughput
Answer:
The answer is "0.77"
Explanation:
The fixed-length segment value = 1
The propagation time of one end to another end is = 3
The Transfer power to move the consumer from the obtained segment = 2
The second last sender assigns a loan = 7 segments
The overall transmission time = 3+2+3 = 8
The maximum throughput value is:
[tex]\to \frac{7}{(1 + 8)}\\\\ \to \frac{7}{9}\\\\\to 0.77[/tex]
Hashing algorithms are used on evidence files to uphold the chain of custody in an investigation. Which of the following is NOT a hashing algorithm?
A. SHA-256
B. MD5
C. DAT-1
D. SHA-1
Answer:
C. DAT-1
Explanation:
Chain of custody is applied when examining digital evidence and checking for proof that no alterations have been made to the document. It ensures that the original piece of digital evidence which could be in text, image, video, or other electronic formats, is preserved and protected from alterations. Hashing algorithms which are mathematical computations that help to condense files are applied during this procedure.
Common hashing algorithms applied, include; the message digest 4, secure hashing algorithms 1, 2, 256, 224, 512, etc. The message digest 4 is used to evaluate why a particular piece of evidence was handled by an individual. This is further authenticated by examining the fingerprint.
#Write a function called string_finder. string_finder should #take two parameters: a target string and a search string. #The function will look for the search string within the #target string. # #The function should return a string representing where in #the target string the search string was found: # # - If search string is at the very beginning of target # string, then return "Beginning". For example: # string_finder("Georgia Tech", "Georgia") -> "Beginning" # # - If search string is at the very end of target string, # then return "End". For example: # string_finder("Georgia Tech", "Tech") -> "End" # # - If search string is in target string but not at the # very beginning or very end, then return "Middle. For # example: # string_finder("Georgia Tech", "gia") -> "Middle" # # - If search string is not in target string at all, then # return "Not found". For example: # string_finder("Georgia Tech", "Idaho") -> "Not found" # #Assume that we're only interested in the first instance #of the search string if it appears multiple times in the #target string, and that search string is definitely #shorter than target string. # #Hint: Don't be surprised if you find that the "End" case #is the toughest! You'll need to look at the lengths of #both the target string and the search string. #Write your function here!
Answer:
I am writing a Python program:
def string_finder(target,search): #function that takes two parameters i.e. target string and a search string
position=(target.find(search))# returns lowest index of search if it is found in target string
if position==0: # if value of position is 0 means lowers index
return "Beginning" #the search string in the beginning of target string
elif position== len(target) - len(search): #if position is equal to the difference between lengths of the target and search strings
return "End" # returns end
elif position > 0 and position < len(target) -1: #if value of position is greater than 0 and it is less than length of target -1
return "Middle" #returns middle
else: #if none of above conditions is true return not found
return "not found"
#you can add an elif condition instead of else for not found condition as:
#elif position==-1
#returns "not found"
#tests the data for the following cases
print(string_finder("Georgia Tech", "Georgia"))
print(string_finder("Georgia Tech", "gia"))
print(string_finder("Georgia Tech", "Tech"))
print(string_finder("Georgia Tech", "Idaho"))
Explanation:
The program can also be written in by using string methods.
def string_finder(target,search): #method definition that takes target string and string to be searched
if target.startswith(search): #startswith() method scans the target string and checks if the (substring) search is present at the start of target string
return "Beginning" #if above condition it true return Beginning
elif target.endswith(search): #endswith() method scans the target string and checks if the (substring) search is present at the end of target string
return "End" #if above elif condition it true return End
elif target.find(search) != -1: #find method returns -1 if the search string is not in target string so if find method does not return -1 then it means that the search string is within the target string and two above conditions evaluated to false so search string must be in the middle of target string
return "Middle" #if above elif condition it true return End
else: #if none of the above conditions is true then returns Not Found
return "Not Found"
Which statement is false?Structures are derived data types.Each structure definition must end with a semicolon.A structure can contain an instance of itself.Structures may not be compared using operators == and !=.
Answer:
A structure can contain an instance of itself
Explanation:
The statement which is known to be false out of the option given is that a structure may comprise or contain an instance of itself. Because to my knowledge, variables of diverse type are always most likely to attributed and contain by a structure.
It is worthy of note that object that aren't similar are utilize in constructing a structure. Another true statement about structure is that a semicolon usually end it's explanation.
Passing structured query language commands to a web application and getting the website to execute it is called SQL script:______.
A) Injection.
B) Processing.
C) Attacking.
D) Execution.
Answer:
(A) Injection
Explanation:
SQL injection is one of the most common web attacks used by attackers to steal data or compromise a web application (especially the database) by inserting or "injecting" SQL queries or commands through the input data from the web application.
In web applications, form inputs are used to make requests to the database either for validation or submission of data by executing queries in the database. If these queries are interfered with by passing query like commands into the form input fields rather than some regular alphanumeric characters, then we have an SQL injection.
When this happens;
i. the attackers can modify an SQL query to return additional results from the database
ii. the attackers can change a query to interfere with the application's regular logic flow.
iii. the attackers can extract sensitive information about the database such as its version and structure.
Write a program that reads ten integers, and then display the number of even numbers and odd numbers. Assume that the input ends with 0. Here is the sample run of the program
Answer:
I am writing a JAVA program. Let me know if you want this program in some other programming language.
import java.util.Scanner; // class to take input from user
class EvenOddNum{ //class name
static void EvenOdd(int array[]) { //function that takes an array as input and displays number of even numbers and odd numbers
int even = 0; // counts even numbers
int odd = 0; //counts odd numbers
for(int i = 0 ; i < array.length-1 ; i++){ //loop through the array elements till the second last array element
if ((array[i] % 2) == 1) { // if the element of array is not completely divisible by 2 then this means its an odd number
System.out.println(array[i]+" = odd"); //display that element to be odd
odd++ ; } //adds 1 to the count of odd every time the program reads an odd number
else{ // if above IF condition evaluates to false then the number is an even number
System.out.println(array[i]+" = even"); //display that element to be odd
even++ ; } } //adds 1 to the count of odd every time the program reads an odd number
System.out.println( "Number of even numbers = " + even); //counts the total number of even integers in the array
System.out.println( "Number of odd numbers = " + odd); } //counts the total number of odd integers in the array
public static void main (String[] args){ //start of main function body
Scanner scan= new Scanner(System.in); //creates Scanner class object
int [] integers = new int[10]; //declares an array named integers that stores 10 integers
System.out.print("Enter numbers: "); //prompts user to enter the integers
for(int i = 0;i<integers.length;i++){ //loops to read the input integers
integers[i] = scan.nextInt(); } //scans and reads each integer value
EvenOdd(integers); } } //calls function EvenOdd to display number of even and odd numbers
Explanation:
The program has a method EvenOdd that takes an array of integers as its parameter. It has two counter variables even and odd. even counts the number of even input integers and odd counts the number of odd input integers. The for loop iterates through each element (integer) of the array except for the last one. The reason is that it is assumed that the input ends with 0 so the last element i.e. 0 is not counted. So the loop iterates to length-1 of the array. The number is odd or even is determined by this if condition: if ((array[i] % 2) == 1) A number is even if it is divisible by 2 otherwise its odd. If the element of array is not completely divisible by 2 i.e. the remainder of the division is not 0 then the number is odd. The modulo operator is used which returns the remainder of the division of number by 2. Each time when an odd or even number is determined, the array[i]+" = even" or array[i]+" = odd" is displayed on the output screen for each integer in the array. Here array[i] is the element of the array and even or odd depicts if that element is even or odd. The last two print statement display the total number of even and odd numbers in the array.

A security administrator is investigating a report that a user is receiving suspicious emails. The user's machine has an old functioning modem installed. Which of the following security concerns need to be identified and mitigated? (Select TWO).
a) Vishing
b) Whaling
c) Spear phishing
d) Pharming
e) War dialing
f) Hoaxing
Answer:
Spear Phishing and War Dialing
Explanation:
So let's tackle these one at a time.
Vishing is simply any type of message (i.e., email, text, phone call, etc.) that appears to be from a trusted source but is not.
Whaling is simply a spear phishing attack of a high-value target such as a CEO or someone with high-level access at a company.
Spear phishing is simply a targeted phishing attack, usually towards a specific person or group of people. (Phishing attack is simply a social attack to try and gain unauthorized access to a resource).
Pharming is an attack that attempts to redirect website traffic to a fake site.
War dialing is a technique to automatically scan a list of numbers in an area in attempt to search for exposed modems, computers, board systems, or fax machines, in order to breach the network.
Hoaxing is simply a social attack that describes a serious threat in attempts to retrieve unauthorized access or money from a victim. (Think microsoft tech support scams)
Now that we have defined these things, let's identify the possible threats that need to be reported.
(a) Vishing? The sec admin report doesn't mention the source of the message so we cannot associate this one
(b) Whaling? The sec admin report says a user, implying someone not high up in the company, but doesn't say it's not someone high up. This is possible.
(c) Spear phishing? The sec admin report says a user, implying that only this user is being targeted so this is definitely valid.
(d) Pharming? The sec admin report says nothing about site redirection.
(e) War dialing? The sec admin report doesn't say anything about unauthorized scanning; however, it mentions the user has an old functioning modem, so this is possible.
(f) Hoaxing? The sec admin report doesn't mention a pop up in the email or the content of the email so we are uncertain.
Thus with these considerations, the two threats that are identified and need mitigation are Spear phishing and War Dialing/Whaling. Note that we aren't positive of the war dialing or whaling, but a case could be made for either; however, given the modem information, the question seems to indicate war dialing.
Which are true of the Transmission Control Protocol (TCP)? Multiple answers: You can select more than one option A it supports full duplex communication B it has graceful connection shutdown C its connections are logical D its data is sent as a discrete messages E it is an end-to-end protocol
Answer:
A, B, C, D and E
Explanation:
Transmission Control protocol (TCP) is a protocol that describes how connections are made and maintained between devices in a network which will help applications in these devices communicate and transmit data.
The following are some of the features of TCP:
i. It supports full duplex communication: In other words, TCP allows for concurrent transmission of data in both directions.
ii. it has a graceful connection shutdown: TCP allows for graceful termination and closing of connection. This means that when there is no more data to be sent by any of the communicating devices, rather than just close connection from its end, it first informs the other device about its completion and asks if it's safe to close the connection. From there, if the other device then says it doesn't have any data to send either, they then reach a consensus to close the connection at their respective ends.
iii. Its connections are logical: TCP makes use of the reliability and flow control mechanisms which require that it initialize and maintain some status information for each stream of data. This status information containing sockets, sequence numbers and window sizes is called a logical connection.
iv. Data is sent as discrete messages: Like other discrete messages, the IP treats the data in TCP as discrete messages by placing them into the IP datagram and transmitting to the target host.
v. It is an end-to-end protocol: TCP governs the way data is transmitted between two devices at their respective ends to ensure reliable delivery. In other words, it is responsible for the transmission of data from a source to one or more destinations. It sits on the operating system of the source and also on the operating system(s) of the destination(s).

Consider these functions:_________.
def f(x) :
return g(x) + math.sqrt(h(x))
def g(x):
return 4 h(x)
def h(x):
return x x + k(x)-1
def k(x):
return 2 (x + 1)
Without actually compiling and running a program, determine the results of the following function calls.
a. x1 = f(2)
b. x2 = g(h(2)
c. x3 = k(g(2) + h(2))
d. x4 - f(0) + f(l) + f(2)
e. x5 - f{-l) + g(-l) + h(-1) + k(-l)
Answer:
x1 = 39
x2 = 400
x3 = 92
x4 = 62
x5 = 0
Explanation:
a. x1 = f(2)This statement calls the f() function passing 2 to the function. The f(x) function takes a number x as parameter and returns the following:
g(x) + math.sqrt(h(x))
This again calls function g() and h()
The above statement calls g() passing x i.e. 2 to the function g(x) and calls function h() passing x i.e. 2 to h() and the result is computed by adding the value returned by g() to the square root of the value returned by the h() method.
The g(x) function takes a number x as parameter and returns the following:
return 4*h(x)
The above statement calls function h() by passing value 2 to h() and the result is computed by multiplying 4 with the value returned by h().
The h(x) function takes a number x as parameter and returns the following:
return x*x + k(x)-1
The above statement calls function k() by passing value 2 to k() and the result is computed by subtracting 1 from the value returned by k() and adding the result of x*x (2*2) to this.
The k(x) function takes a number x as parameter and returns the following:
return 2 * (x + 1)
As the value of x=2 So
2*(2+1) = 2*(3) = 6
So the value returned by k(x) is 6
Now lets go back to the function h(x)
return x*x + k(x)-1
x = 2
k(x) = 6
So
x*x + k(x)-1 = 2*2 + (6-1) = 4 + 5 = 9
Now lets go back to the function g(x)
return 4*h(x)
As x = 2
h(x) = 9
So
4*h(x) = 4*9 = 36
Now lets go back to function f(x)
return g(x) + math.sqrt(h(x))
As x=2
g(x) = 36
h(x) = 9
g(x) + math.sqrt(h(x)) = 36 + math.sqrt(9)
= 36 + 3 = 39
Hence
x1 = 39b. x2 = g(h(2) )The above statement means that first the function g() calls function h() and function h() is passed a value i.e 2.
As x=2
The function k() returns:
2 * (x + 1) = 2 * (2 + 1) = 6
The function h() returns:
x*x + k(x)-1 = 2*2 + (6-1) = 4 + 5 = 9
Now The function g() returns:
4 * h(x) = 4 * h(9)
This method again calls h() and function h() calls k(). The function k() returns:
2 * (x + 1) = 2 * (9 + 1) = 20
Now The function h() returns:
x*x + k(x)-1 = 9*9 + (20-1) = 81 + 19 = 100
h(9) = 100
Now The function g() returns:
4 * h(x) = 4 * h(9) = 4 * 100 = 400
Hence
x2 = 400c. x3 = k(g(2) + h(2))g() returns:
return 4 h(x)
h() returns:
return x*x + k(x)-1
k(2) returns:
return 2 (x + 1)
= 2 ( 3 ) = 6
Now going back to h(2)
x * x + k(x)-1 = 2*2 + 6 - 1 = 9
Now going back to g(2)
4 h(x) = 4 * 9 = 36
So k(g(2) + h(2)) becomes:
k(9 + 36 )
k(45)
Now going to k():
return 2 (x + 1)
2 (x + 1) = 2(45 + 1)
= 2(46)
= 92
So k(g(2) + h(2)) = 92
Hence
x3 = 92d. x4 = f(0) + f(1) + f(2)Compute f(0)
f() returns:
return g(0) + math.sqrt(h(0))

return 1*1 + k(1)-1
h() calls k()
k() returns:
return 2 * (1 + 1)
2 * (1 + 1) = 4
Going back to caller function h()
Compute h(0)
1*1 + k(1)-1 = 1 + 4 - 1 = 4
Going back to caller function g()
Compute g(1)
4 * h(1) = 4 * 4 = 16
Going back to caller function f()
compute f(1)
g(1) + math.sqrt(h(1)) = 16 + 2 = 18
f(1) = 18
Compute f(2)
f() returns:
return g(2) + math.sqrt(h(2))
f() calls g() and h()
g() returns:
return 4 * h(2)
g() calls h()
h() returns
return 1*1 + k(2)-1
h() calls k()
k() returns:
return 2 * (2+1)
2 * (3) = 6
Going back to caller function h()

2*2 + k(2)-1 = 4 + 6 - 1 = 9

Going back to caller function f()
compute f(2)
g(2) + math.sqrt(h(2)) = 36 +3 = 39
f(1) = 13.7
Now
x4 = f(0) + f(l) + f(2)
= 5 + 18 + 39
= 62

In Network Address and Port Translation (NAPT), which best describes the information used in an attempt to identify the local destination address?
Answer:
Hello your question lacks the required options here are the options
source IP and destination IPsource IP and destination portsource IP and source portsource port and destination IPsource port and destination portanswer : source IP and destination port
Explanation:
The information that is used in an attempt to identify the local destination address is the source IP and destination port
source IP is simply the internet protocol address of a device from which an IP packet is sent to another device while destination port are the ports found in a destination device that receives IP packets from source ports they are found in many internet applications
Why is a DNS cache poisoning attack dangerous? Check all that apply. A. Errrr...it's not actually dangerous. B. It allows an attacker to redirect targets to malicious webservers. C. It allows an attacker to remotely controle your computer. D. It affects any clients querying the poisoned DNS server.
Answer:
(B) It allows an attacker to redirect targets to malicious webserver.
(D) It affects any clients querying the poisoned DNS server.
Explanation:
DNS cache poisoning is a serious type of attack that is designed to exploit the vulnerabilities inherent in a Domain Name Server (DNS) where a user is redirected from a real server to a fake one. It is also called DNS spoofing.
Normally, when your browser tries to visits a website through a given domain name, it goes through the DNS server. A DNS server maintains a list of domain names and their equivalent Internet Protocol addresses. This server (DNS) then responds to the request with one or more IP addresses for the browser to reach the website through the domain name.
The computer browser then get to the intended website through the IP address.
Now, if the DNS cache is poisoned, then it has a wrong entry for IP addresses. This might be via hacking or a physical access to the DNS server to modify the stored information on it. Therefore, rather than responding with the real IP address, the DNS replies with a wrong IP address which then redirects the user to an unreal website.
Although they might not be able to control your computer remotely as long as you are not trying to visit a web page via the poisoned information, there are other dangers attached to this type of attack.
Once the DNS server has been poisoned, any client trying to query the server will also be affected since there is no direct way of knowing if the information received from the server is actually correct.
When you sustain program implementation by staying true to the original design, it is termed A. Goals and objectives B. Program fidelity C. Program evaluation D. Program management
Answer:
Program fidelity
Explanation:
A technician wants to configure the inbound port of a router to prevent FTP traffic from leaving the LAN.
Which of the following should be placed on the router interface to accomplish this goal?
A. Static routes for all port 80 traffic
B. DHCP reservations for all /24 subnets
C. ACL for ports 20 and 21
D. MAC filtering using wildcards
Answer:
The technician will want to add ACL for ports 20 and 21
Explanation:
The FTP protocol by default will attempt to use 21 for TCP access and 20 for data access. By enabling an Access Control List (ACL) on ports 20 and 21, the technician can prevent FTP traffic from leaving the network on the default ports.
Cheers.
Draw the BST where the data value at each node is an integer and the values are entered in the following order 36,22,10,44,42,16,25,3,23,24 solution
Answer and Explanation:
A BST is the short form for Binary Search Tree. It is a special type of binary tree data structure in which nodes are arranged in a particular order such that;
i. the left subtree of a particular node should always contain nodes whose key values are less than that of the key value of the node itself.
ii. the right subtree of a particular node should always contain nodes whose key values are greater than that of the key value of the node itself.
iii. the right and left subtrees should also be a binary search tree.
For the given set of data:
36,22,10,44,42,16,25,3,23,24;
The equivalent binary search tree is attached to this response.
As shown in the attachment:
i. the first data value (36) is the root node value.
ii. the second value (22) is less than the root node value (36), therefore, 22 goes to the left of the root node.
iii. the third value is 10. This is less than 36 and then also less than 22, so 10 goes to the left of 22.
iv. the fourth value is 44. This is greater than the root node value (36), therefore, 44 goes to the right of the root node.
v. the fifth value is 42. This is greater than the root value (36) so it is going to be positioned somewhere at the right of the root node. But it is less than the value (44) of the direct right node of the root node. Therefore, 42 goes to the left of the direct right (44) of the root node.
vi. the sixth value is 16. This is less than the root node value (36). So it is going to be positioned somewhere at the left of the root node. It is also less than the value (22) of the direct left node of the root node. So it is going to be positioned somewhere at the left of the node with 22. But it is greater than the node with 10. Therefore, 16 is going to be to the right of the node with 10.
This trend continues until all data values have been rightly positioned.
PS: A binary tree is a data structure in which each node cannot have more than two nodes directly attached to it.
The machine has to be returned to the vendor for proper recycling. Which stage of the hardware lifecycle does this scenario belong to?
Answer:
Decommission/Recycle
Explanation:
This specific scenario that is being described belongs to the final stage of the hardware lifecycle known as Decommission/Recycle. This is when the asset in question has completed its function for an extended period of time and is no longer functioning at maximum efficiency and/or newer hardware has hit the market. Once in this stage, the hardware in question is either repaired or scrapped for resources that can be used to create newer products.
