Answer:

Let f be a function  

a) f(n) = n²  

b) f(n) = n/2  

c) f(n) = 0  

Explanation:  

a) f(n) = n²  

This function is one-to-one function because the square of two different or distinct natural numbers cannot be equal.  

Let a and b are two elements both belong to N i.e. a ∈ N and b ∈ N. Then:

                               f(a) = f(b) ⇒ a² = b² ⇒ a = b  

The function f(n)= n² is not an onto function because not every natural number is a square of a natural number. This means that there is no other natural number that can be squared to result in that natural number.  For example 2 is a natural numbers but not a perfect square and also 24 is a natural number but not a perfect square.  

b) f(n) = n/2  

The above function example is an onto function because every natural number, let’s say n is a natural number that belongs to N, is the image of 2n. For example:

                               f(2n) = [2n/2] = n  

The above function is not one-to-one function because there are certain different natural numbers that have the same value or image. For example:  

When the value of n=1, then

                                  n/2 = [1/2] = [0.5] = 1  

When the value of n=2 then  

                                   n/2 = [2/2] = [1] = 1  

c) f(n) = 0

The above function is neither one-to-one nor onto. In order to depict that a function is not one-to-one there should be two elements in N having same image and the above example is not one to one because every integer has the same image.  The above function example is also not an onto function because every positive integer is not an image of any natural number.

Answer:

A bandwidth is the maximum rate of transfer of data across a given path

Latency refers to the delay of data to travel or move between a source and destination

An example of a high bandwidth and high latency network is the Satellite Internet connectivity.

An example of a low bandwidth and latency network is the telephone system connection.

Explanation:

Solution

Bandwidth: Bandwidth determines how fast data can be transferred for example, how many bits/sec it can transport.

Latency: It refers to the delay or how long it takes for data to travel between it's source and destination.

An example of a high bandwidth and high latency network is the Satellite internet connection.

Satellite internet connection: This is responsible for the connectivity of several systems, it has a high bandwidth, since satellite are in space, due to distance it has a high latency.

So, satellite internet connection is compensated with high latency and high bandwidth.

An example of a low bandwidth and low latency network is the Telephony network.

Telephone/telephony internet connection: This connection does not have much data for transfer. it has low size audio files of which a low bandwidth range. also for both end or end users to understand and talk to each other, it has low latency.

An example of a network that exhibits high bandwidth but also high latency is Satellite internet connection.

An example of one that has both low bandwidth and low latency is telephony internet connection.

Based on the provided information, we can say that Satellite internet connection posses high bandwidth but also high latency because, the fastness of data transfer is based on the bandwidth and how the data to travel between it's source and destination is based on its latency.

We can conclude that telephony internet connection has low bandwidth and low latency because of low data transfer is required.

Answer & Explanation:

To print 10 on a line and each number separated by space; you make the following modifications.

print(str(i)+" ",end=' ')

str(i)-> represents the actual number to be printed

" "-> puts a space after the number is printed

end = ' ' -> allows printing to continue on the same line

if(count == 10):

     print(' ')

The above line checks if count variable is 10;

If yes, a blank is printed which allows printing to start on a new line;

The modified code is as follows (Also, see attachment for proper indentation)

count = 0

for i in range(100,201):

     if(i%6 == 0 and i%5!=0) or (i%5 ==0 and i%6!=0):

           print(str(i)+" ",end=' ')

                 print(' ')

                 count = 0

Answer:

The question seem incomplete as the list is not given and the programming language is not stated;

To answer this question, I'll answer this question using Python programming language and the program will allow user input.

Input will stop until user enters 0

The program is as follows

newlist = []

print("Input into the list; Press 0 to stop")

userinput = int(input("User Input:"))

while not userinput == 0:

     newlist.append(userinput)

     userinput = int(input("User Input:"))

is_ascending = "True"

i = 1

while i < len(newlist):  

     if(newlist[i] < newlist[i - 1]):  

           is_ascending = "False"

     i += 1

print(newlist)

print(is_ascending)

Explanation:

This line declares an empty list

newlist = []

This line prompts gives instruction to user on how to stop input

print("Input into the list; Press 0 to stop")

This line prompts user for input

userinput = int(input("User Input:"))

This next three lines takes input from the user until the user enters 0

while not userinput == 0:

     newlist.append(userinput)

     userinput = int(input("User Input:"))

The next line initialized "True" to variable is_ascending

is_ascending = "True"

The next 5 line iterates from the index element of the list till the last to check if the list is sorted

i = 1

while i < len(newlist):  

     if(newlist[i] < newlist[i - 1]):  

           is_ascending = "False"

     i += 1

The next line prints the list

print(newlist)

The next line prints the value of is_ascending

print(is_ascending)

This is the complete question:

for i ∈ {1,2,3,4,5,6} do  beep  

for j ∈ {1,2,3,4} do  beep  

for k ∈ {1,2,3} do

    for l ∈ {1,2,3,4,5} do beep  

for m ∈ {1,2,3,4} do  beep

Explanation:

I will explain the algorithm line by line.

for i ∈ {1,2,3,4,5,6} do  beep  

This statement has a for loop and i variable that can take the values from 1 to 6. As there are 6 possible values for i so the beep statement gets executed 6 times in this for loop.

for j ∈ {1,2,3,4} do  beep  

This statement has a for loop and j variable that can take the values from 1 to 4. As there are 4 possible values for j so the beep statement gets executed 4 times in this for loop.

for k ∈ {1,2,3} do

    for l ∈ {1,2,3,4,5} do beep  

There are two statements here. The above statement has a for loop and k variable that can take the values from 1 to 3. As there are 3 possible values for k so the beep statement gets executed 3 times in this for loop. The below statement has a for loop and l variable that can take the values from 1 to 5. As there are 5 possible values for l so the beep statement gets executed 5 times in this for loop. However these statement work like an inner and outer loop where the outer loop is k and inner one is l which means 1 gets executed for each combination of values of k and l. As there are three values for k and 5 possible values for l so the combinations of values of k and l is 15 because 3 * 5 = 15. Hence the beep statement gets executed 15 times.

for m ∈ {1,2,3,4} do  beep

This statement has a for loop and m variable that can take the values from 1 to 4. As there are 4 possible values for m so the beep statement gets executed 4 times in this for loop.

Now lets take the sum of all the above computed beeps.

for i = 6 beeps

for j = 4 beeps

for k and l possible combinations = 15 beeps

for m = 4 beeps

total beeps = 6 + 4 + 15 + 4 = 29 beeps

Answer:

Explanation:

Firstly, declare the necessary variables and initialize them with zero (Line 4-8). Next create a Scanner object to get user input for score (Line 10). Create a while loop by using the counter as limit (Line 12). In the while loop, prompt user to input a number between 1 - 100 (Line 13-14). Create another while loop to check the input must be between 1 - 100 or it will print invalid message and ask for user input again (Line 15-19).

Next, create an if-else statement to check if the current score is equal or above 60. If so print pass if not print fail (Line 21-27). At the same time increment the fail and pass counter.

Create another two if statement to get the current highest and lowest score and assign them to highest and lowest variables, respectively (Line 29-35).

Increment the counter by one before proceeding to the next loop to repeat the same process (Line 37).

At last, print the required output after finishing the while loop (Line 40-43).

Answer:

The answer is The Cache Sets (S) = 32, Tag bits (t)=24, Set index bits(s) = 5 and Block offset bits (b) = 3

Explanation:

Solution

Given Data:

Physical address = 32 bit (memory address)

Cache size = 1024 bytes

Block size = 8 bytes

Now

It is a 4 way set associative mapping, so the set size becomes 4 blocks.

Thus

Number of blocks = cache size/block size

=1024/8

=128

The number of blocks = 128

=2^7

The number of sets = No of blocks/set size

=128/4

= 32

Hence the number of sets = 32

←Block ←number→

Tag → Set number→Block offset

←32 bit→

Now, =

The block offset = Log₂ (block size)

=Log₂⁸ = Log₂^2^3 =3

Then

Set number pc nothing but set index number

Set number = Log₂ (sets) = log₂³² =5

The remaining bits are tag bits.

Thus

Tag bits = Memory -Address Bits- (Block offset bits + set number bits)

= 32 - (3+5)

=32-8

=24

So,

Tag bits = 24

Therefore

The Cache Sets = 32

Tag bits =24

Set index bits = 5

Block offset bits = 3

Note: ←32 bits→

Tag 24 → Set index  5→Block offset 3

Replace /* Your solution goes here */ with the following code segment

srand(seedVal);

cout<<rand()%(int)(9 - 0 + 1) + 0<<endl;

cout<<rand()%(int)(9 - 0 + 1) + 0<<endl;

Explanation:

From the code segment, the seedVal has already been declared and initialized to 0; The next step is to seed it as random number using srand.

The first line of the code segment in the Answer section "srand(seedVal); " is used to achieve that task.

Having done that, the next step is to write statements to generate the two random numbers using rand();

When generating random numbers, two things are to be noted;

Here, the lower bound is 0 and the upper bound is 9;

C rand() function uses the following syntax to generate random numbers

rand()%(int)(U - L + 1) + L

Where U = 9 and L = 0

Replacing U and L with there respective values; the syntax becomes

rand()%(int)(9 - 0 + 1) + 0

So, the two print statements will be written as

cout<<rand()%(int)(9 - 0 + 1) + 0;

Also, the question states that, each print statement be ended with a new line;

So, the print statements will be

cout<<rand()%(int)(9 - 0 + 1) + 0<<endl;

Alternatively, by solving (9 - 0 + 1) + 0; the statements can be written as

cout<<rand()%(int)(10)<<endl;

Conclusively, the complete statements is as follows;

srand(seedVal);

cout<<rand()%(int)(9 - 0 + 1) + 0<<endl;

cout<<rand()%(int)(9 - 0 + 1) + 0<<endl;

or

srand(seedVal);

cout<<rand()%(int)(10)<<endl;

cout<<rand()%(int)(10)<<endl;

Security Configuration Wizard saves any changes that are made as a role- or function-specific security policy which can be used as a baseline and applied to other servers in the network.

After checking the Group policy by an administrator, any changes made as a role- or function-specific security policy by the Security Configuration Wizard (SCW) is used as a baseline and can be applied either immediately or sometimes in the future to other servers in the network after testing it in a well secured environment.

Basically, the Microsoft Security Configuration Wizard (SCW) typically help administrators in running the following;

1. Role-Based Service Configuration.

2. Registry settings.

3. Network and Firewall Security settings.

4. Auditing Policy settings.

8  16  32  64

Lets see while loop to check what you did wrong in your program:

The while loop checks if numInsects is less than 100. It is true as numInsects =8 which is less than 100.

So the body of while loop executes. numInsects = numInsects * 2;  statement in the body multiplies the value of numInsects i.e 8 with 2 and then cout << numInsects << " ";  prints the value of numInsects  AFTER the multiplication with 2 is performed. So 8 is not printed in output but instead 16 (the result of 8*2=16) is printed as the result of first iteration.

So lets change the while loop as follows:

while (numInsects < 100) {

cout << numInsects << " ";

numInsects = numInsects * 2;

Now lets see how it works.

The while loop checks if numInsects is less than 100. It is true as numInsects =8 which is less than 100

So the body of while loop executes. cout << numInsects << " "; first prints the value of numInsects i.e. 8. Next numInsects = numInsects * 2;  multiplies the value of numInsects i.e 8 with 2. So first 8 is printed on the output screen. Then the multiplication i.e. 8*2=16 is performed as the result of first iteration. So now value of numInsects becomes 16.

Next the while loop condition numInsects < 100 is again checked. It is true again as 16<100. Now cout << numInsects << " "; is executed which prints 16. After this, the multiplication is again performed and new value of numInsects becomes 32 at second iteration. This is how while loops continues to execute.

So this while loop stops when the value of numInsects exceeds 100.

Answer:

d. Port mirror

Explanation:

Port mirroring is a method to monitor network traffic and it is used in the Intrusion Detection Systems. It is also called Switched Port Analyzer and is used to analyse the network errors. This technique basically copies the network packets and sends or transmits these copied packed from one port to another in a network device such as a switch. This means that this technique is used to copy the network packets from one switch port and send the copy of these packets to another port where these packets are monitored. This is how it analyses the network errors and incoming traffic for irregular behavior and also this can be done without affecting the normal operation of the switch and other network processes. It is simple, inexpensive and easy to establish and use. The most important advantage of using mirrored ports is that it catches the traffic on several ports at once or can capture all of the network traffic.

Answer:

The overview of the given question is described in the explanation segment below.

Explanation:

The number of casualties has occurred in recent years. The following are indeed the assaults:

Arbitrary Remote Code execution attacks:

It's also a very hazardous assault. Unsanitary working on implementing that used operating system including user actions could enable an attacker to execute arbitrary functions mostly on system files.

Sites become targeted with such a DOS assault that will cause them inaccessible whether they close the account to an offender who threatens them.

Prevention: We could protect this by preventing the call from additional assessment by the user. We will disinfect input validation if we transfer values to devise calls. The input data is permitted to transfer on requests, it should have been strictly regulated although restricted to a predetermined system of principles.

Injection attack:

The object of the Injection Attack seems to be to delete vital information from the server. Throughout the list, we have such a user, a code, as well as a lot of several other essential stuff. Assailants are taking vital data and doing the wrong stuff. This can have an impact on the web site or software application interface the SQL.

Prevention: Parameterized functions require developers must specify all of the SQL code, and afterward move the question in-parameter, allowing the server to distinguish between some of the code as well as the information. By decreasing the privilege allocated to each database. White list data validation has been used to prevent abnormal information.

Zero-day attack:

It corresponds to something like a vulnerability flaw undisclosed to the user. The security vulnerability becomes infected with malware. The attackers have access to inappropriate details.

Prevention: The organizations are releasing the patch fixes the found holes. The updated plugin is also a preventive tool.

Buffer overflow attack:

This is indeed a major security threat to the accuracy of the data. This overflow happens since more information becomes set to either a specified size than even the buffer could accommodate. Adjoining program memory is compromised. During that time, the attacker was indeed running obfuscated code. Two key forms of such attack are provided below:

Prevention: Standard library features, including such strcpy, should indeed be avoided. Standard testing should be performed to identify as well as resolve overflow.

Answer:

During a traceroute, the router decreases the Time To Live values of the packet sent from the traceroute by one during routing, discards the packets whose Time To Live values have reached zero, returning the ICMP error message ICMP time exceeded.

Explanation:

Traceroute performs a route tracing function in a network. It is a network diagnostic commands that shows the path followed, and measures the transit delays of packets across an Internet Protocol (IP) network, from the source to the destination, and also reports the IP address of all the routers it pinged along its path. During this process, the traceroute sends packets with Time To Live values that increases steadily from packet to packet; the process is started with Time To Live value of one. At the routers, the Time To Live values of the packets is gradually decreased by one during routing, and the packets whose Time To Live values have reached zero are discarded, returning the ICMP error message ICMP Time Exceeded

Answer:

current_price = int(input("Enter the current price: "))

last_months_price = int(input("Enter the last month's price: "))

print("This house is $" + str(current_price))

print("The change is $" + str(current_price - last_months_price) + " since last month")

print("The estimated monthly mortgage is ${:.2f}".format((current_price * 0.051) / 12))

Explanation:

Ask the user to enter the current price and last month's price

Print the current price

Print the change in the price, subtract the last month's price from the current price

Print the estimated monthly mortgage, use the given formula to calculate, in required format
