Answer:
B. 640,000 bits
Explanation:
From the given question,
The voice line has 24 channels with each having the capacity for 1 telephone conversation with the size of 8 bits and 8, 000 samples/second.
Thus for a 10 seconds clip, the rate = 8 000 × 10
= 80 000
The rate is 80 000 samples/second.
The size of the storage in bits = rate ×8 bits
= 80 000 × 8
= 640 000 bits
Therefore, the size of the storage required for storing the video clip on disk is 640 000 bits.

Describe any five GSM PLMN basic services?
Answer:
Your answer can be found in the explanation below.
Explanation:
GSM is the abbreviation for Global System for Mobile communication. Its purpose is to transmit voice and data services over a range. It is a digital cellular technology.
PLMN is the abbreviation for Public Land Mobile network. It is defined as the wireless communication service or combination of services rendered by a telecommunication operator.
The plmn consists of technologies that range from Egde to 3G to 4G/LTE.
PLMN consists of different services to its mobile subscribers or users but for the purpose of this question, i will be pointing out just 5 of them alongside its definitions.
1. Emergency calls services to fire or police: Plmn provides us with the option to make emergency calls in the event of any accident or fire incident, etc.It is available on devices either when locked or unlocked.
2. Voice calls to/from other PLMN: This entails the putting of calls across to persons we cannot reach very quickly. PLMN helps to connect persons through its network of from other networks thus making communication easier.
3. Internet connectivity: PLMN provieds us with internet services through wifi or bundles that enable us have access to the internet as well as help us communicate with people and loved ones over a distance. Internet service are possble either on GPRS or 3G or 4G networks.
4. SMS service: SMS means short messaging service. This is also know as text messages. PLMN allows us to be able to send short messages to people as oppposed to mails. It is mostly instant and can be sent or recieved from the same PLMN or others.
5. MMS service: Multimedia messaging service whose short form is MMS ccan be descibed as the exchange of heavier messages such as a picture or music or document but not from an email. It is availabel for use from one PLMN to another.

Write a complete program that reads 6 numbers and assigns True to variable isAscending if the numbers are in ascending order. Otherwise assign False to it. Display the value of isAscending. Here are three sample runs: Sample Run 1 Enter six numbers: 4 6 8 10 11 12 True Sample Run 2 Enter six numbers: 4 6 3 10 11 12 False Sample Run 3 Enter six numbers: 41 6 3 10 11 12 False Note: Your program must match the sample run exactly.
Answer:
The programming language is not stated;
For this, I'll answer your question using c++ programming language
The program does not make use of comments (See explanation for further details)
From the sample run, the input numbers are integer; So, this program assumes that all input will be integer...
Program starts here
#include<iostream>
using namespace std;
int main()
{
cout<<"Enter six numbers: ";
int Arr[6];
for(int i = 0;i<6;i++)
{
cin>>Arr[i];
}
bool flag = true;
for(int i = 0;i<6;i++)
{
for(int j = i;j<6;j++)
{
if(Arr[i]>Arr[j])
{
flag = false;
}
}
}
string isAscending;
if(flag)
{
isAscending = "True";
}
else
{
isAscending = "False";
}
cout<<isAscending;
return 0;
}
Explanation:
cout<<"Enter six numbers: "; -> This line prompts the user for input
int Arr[6]; -> The input is stored in an array; This line declares the array
The following for loop iteration is used to iterate through the array
for(int i = 0;i<6;i++)
{
cin>>Arr[i]; -> This line accepts user input
}
bool flag = true; -> A boolean variable is initialized to true
The following nested loop checks if numbers are in ascending order
for(int i = 0;i<6;i++)
{
for(int j = i;j<6;j++)
{
if(Arr[i]>Arr[j]) -> This particular if statement checks if a number is greater than the next number
{
flag = false; -> If yes, the boolean variable is changed to false
}
}
} - > The nested loop ends here
string isAscending = "True"; -> Here, isAscending is declared as string
if(flag) If boolean variable flag is true; i
{
isAscending = "True"; "True" is assigned to isAscending
}
else -> Otherwise; if boolean variable flag is no longer true; i.e if it's false
{
isAscending = "False"; -> "False" is assigned to isAscending
}
cout<<isAscending; -> The corresponding value of isAscending is printed
The complete program that reads 6 numbers and assigns True to variable isAscending if the numbers are in ascending order is as follows;
number = 0
list1 = []
while number < 6:
x = input("enter six number: ")
number += 1
list1.append(x)
if sorted(list1)==list1:
print("True")
else:
print("False")
Code explanation:The code is written in python
The variable "number" is initialise to zero.We declared an empty list to unpack our numbers.while number is less than 6, we ask the user for inputs and increased the value of number for the loop to continue. we append the users input to the list1.If the sorted value of the list1 is equals to the list1, then we print True Else we print Falselearn more on python here: https://brainly.com/question/26104476
Write a program that displays, 10 numbers per line, all the numbers from 100 to 200 that are divisible by 5 or 6, but not both. The numbers are separated by exactly one space
My Code:
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), "")
count = count + 1
if count == 10:
string = str(i) + str("")
print(string)
count = 0
Any way to put the numbers 10 per line?
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=' ')
count = count + 1
if(count == 10):
print(' ')
count = 0
Determine the number of cache sets (S), tag bits (t), set index bits (s), and block offset bits (b) for a 1024-byte 4-way set associative cache using 32-bit memory addresses and 8-byte cache blocks.
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
Given positive integer numInsects, write a while loop that prints that number doubled without reaching 100. Follow each number with a space. After the loop, print a newline. Ex: If numInsects = 8, print:
8 16 32 64
#include
using namespace std;
int main() {
int numInsects = 0;
numInsects = 8; // Must be >= 1
while (numInsects < 100) {
numInsects = numInsects * 2;
cout << numInsects << " ";
}
cout << endl;
return 0;
}
So my question is what am I doing wrong?
Answer:
The cout<<numInsects<<""; statement should be placed before numInsects = numInsects * 2; in the while loop.
Explanation:
Your program gives the following output:
16 32 64 128
However it should give the following output:
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.
The performance of a client-server system is strongly influenced by two major network characteristics: the bandwidth of the network (how many bits/sec it can transport) and the latency (how many seconds it takes for the first bit to get from the client to the server). Give an example of a network that exhibits high bandwidth but also high latency. Also give an example of one that has both low bandwidth and low latency. Justify/explain your answers. (
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.

Implement a Java program using simple console input & output and logical control structures such that the program prompts the user to enter 5 integer scores between 0 to 100 as inputs and does the following tasks For each input score, the program determines whether the corresponding score maps to a pass or a fail. If the input score is greater than or equal to 60, then it should print "Pass", otherwise, it should print "Fail". After the 5 integer scores have been entered, the program counts the total number of passes as well as the total number of failures and prints those 2 count values with appropriate messages like "Total number of passes is: " & "Total number of failures is: ". After the 5 integer scores have been entered, the program finds the highest score as well as the lowest score and prints those 2 values with appropriate messages like "Highest score is: " & "Lowest score is: ". The program checks whether an input score is a number between 0 - 100 or not. If the input score value is otherwise or outside the above range, then it prints the error message saying "Invalid score" and prompts the user for valid input.
Answer:
import java.util.Scanner; public class Main { public static void main(String[] args) { int pass = 0; int fail = 0; int highest = 0; int lowest = 100; int counter = 0; Scanner input = new Scanner(System.in); while(counter < 5){ System.out.print("Input a score between 0 to 100: "); int score = input.nextInt(); while(score < 0 || score > 100){ System.out.println("Invalid score."); System.out.print("Input a score between 0 to 100: "); score = input.nextInt(); } if(score >= 60 ){ System.out.println("Pass"); pass++; }else{ System.out.println("Fail"); fail++; } if(highest < score ){ highest = score; } if(lowest > score){ lowest = score; } counter++; } System.out.println("Total number of passes is: " + pass); System.out.println("Total number of failures is: " + fail); System.out.println("Highest score is: " + highest); System.out.println("Lowest score is: " + lowest); } }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).

Write a program with two inputs, current price and last month's price (both integers). Then, output a summary listing the price, the change since last month, and the estimated monthly mortgage computed as (current_price * 0.051) / 12. Output each floating-point value with two digits after the decimal point, which can be achieved as follows: print('{:.2f}'.format(your_value)) Ex: If the input is: 200000 210000 the output is: This house is $200000. The change is $-10000 since last month. The estimated monthly mortgage is $850.00.
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))

Consider the following algorithm. 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 How many times does a beep statement get executed?
Answer:
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
Design and implement a program (name it Youth) that reads from the user an integer values repressing age (say, age). The program prints out the entered values followed by a message as follows: If age is less or equal to 21, the message is "Age is a state of mind.". Finally, the program always prints out the message "Age is a state of mind." Format the outputs following the sample runs below.
Sample run 1:
You entered: 20
Youth is a wonderful thing. Enjoy.
Age is a state of mind.
Answer:
The programming language is not stated; I'll answer this question using C++ programming language;
Another thing to note is that; the sample run is quite different from the illustration in the question; So, I'll assume the program to print "Youth is a wonderful thing. Enjoy.", if and only if age is less than or equal to 21
The program is as follows
#include<iostream>
using namespace std;
int main() {
int age;
int i =1;
start:
cout<<"Sample run: "<<i<<endl;
cout<<"You entered: ";
cin>>age;
if(age<=21) {
cout<<"Youth is a wonderful thing. Enjoy."<<endl; }
cout<<"Age is a state of mind"<<endl;
i++;
cout<<"Run another? (Y/N): ";
char resp;
cin>>resp;
if(resp=='Y')
{
goto start;
}
return 0;
}
Explanation:
Line 4 of the program declares age as integer
Line 5 declares and initializes a counter variable, i to 1
Line 6 is used as a label to start another sample run
Line 7 prints the Sample run in the following format;
Sample run 1, during the first iteration
Sample run 2, during the second iteration; and so on...
Line 8 prompts the user to supply details for age
Line 9 stores user input in variable age
Line 10 checks if age is less than or equal to 21
If true, the program outputs Youth is a wonderful thing. Enjoy., then it continues execution on line 23
Otherwise, it jumps directly to line 23 and outputs Age is a state of mind
The counter is increased by 1 on line 24
The program asks if the user wants to take another sample run on line 25
The response is saved in a char variable on line 27
If the user response is Y, the program goes to the label on line 6 to begin another iteration
Otherwise, the program is terminated.

A security analyst is interested in setting up an IDS to monitor the company network. The analyst has been told there can be no network downtime to implement the solution, but the IDS must capyure all of the network traffic. Which of the following should be used for the IDS implementation?
a. Network tap
b. Honeypot
c. Aggregation
d. Port mirror
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.
You learn that in a previous security breach at GearUp, a disgruntled employee destroyed the encryption key that had been used to protect data. How will you prevent a similar data safeguard problem at GearOn
Answer:
The data can be safeguarded using key escrow procedure.
Explanation:
Key escrow basically means to store the cryptographic key in an "escrow" by a reputable trusted third party. The copy of the encryption key is kept with the third party. In case the cryptographic key gets lost or destroyed, then the key escrow service helps to access the encrypted data. It also manages the access control to the key in case the key gets lost. So this way in case of security breach at GearOn the key escrow service can be used to re-implement or access the key easily.

In the given case, 'transform binary or unary M:N relationship' can be created using 'the primary key linked with the relationship plus any non-key aspects of the relationship and the primary keys of the related entities' as it displays the existence of a relationship between the occurrences of a similar set of the entity i.e. associative entity here.
Supposethatyoubet$5oneachofasequenceof50independentfairgames. Usethecentrallimittheorem to approximate the probability that you will lose more than $75
Answer:
0.119
Explanation:
50 independent fair games
Mean will be 50/2 = 25
Standard deviation of the loosing probability is :
[tex]\sqrt{50*0.5*0.5}[/tex] * 10 = 33.536
we have to loose 33 times out of 50 games.
To find the approximate probability we use z- value table.
z value = [tex]\frac{33-25}{3.35}[/tex]
z - value = 2.2659
Looking at the z-value table we get 0.119.
Denial of service (DoS) attacks can cripple an organization that relies heavily on its web application servers, such as online retailers. What are some of the most widely publicized DoS attacks that have occurred recently? Who was the target? How many DoS attacks occur on a regular basis? What are some ways in which DoS attacks can be prevented? Write a one-page paper on your research.
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:
Heap-basedStack-basedPrevention: Standard library features, including such strcpy, should indeed be avoided. Standard testing should be performed to identify as well as resolve overflow.
Write VHDL code for a RAM that has 16 locations each 32 bits wide. There will be a chipselect (CS) input that activates the chip. Another input to the circuit is an R/W which determines if the operation is a read or a write to the chip. The address input to the chip is a vector. The input and output would also be a vector(s) that should send and receive the data, depending on the address input to the chip.
Answer:
Hello your question lacks some parts attached is the complete question and the solution is written in the explanation
Explanation:
VHDL CODE::::::
VHDL Code for RAM Design:
library IEEE;
use IEEE.STD_LOGIC_1164.ALL;
use IEEE.STD_LOGIC_ARITH.ALL;
use IEEE.STD_LOGIC_UNSIGNED.ALL;
entity RAM_32Bits is
port (
Clk: in std_logic;
CS: in std_logic;
RW: in std_logic;
Address: in std_logic_vector(3 downto 0);
Data_In: in std_logic_vector(31downto 0);
Data_Out: out std_logic_vector(31downto 0);
)
end entity RAM_32Bits;
architecture RAM_32 of RAM_32Bits is
// Declare Memory Array
type RAM is array (3 downto 0) of std_logic_vector(31 downto 0);
signal mem_array: ram;

Assign True to the variable is_ascending if the list numbers is in ascending order (that is, if each element of the list is greater than or equal to the previous element in the list). Otherwise, assign False with is_ascending.
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)

Give an example of a function from N to N that is: Hint: try using absolute value, floor, or ceiling for part (b). (a) one-to-one but not onto (b) onto but not one-to-one (c) neither one-to-one nor onto
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.
During a traceroute, which action does a router perform to the value in the Time To Live (TTL) field?
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

Define a function is_prime that receives an integer argument and returns true if the argument is a prime number and otherwise returns false. (An integer is prime if it is greater than 1 and cannot be divided evenly [with no remainder] other than by itself and one. For example, 15 is not prime because it can be divided by 3 or 5 with no remainder. 13 is prime because only 1 and 13 divide it with no remainder.) This function may be written with a for loop, a while loop or using recursion. Use the up or down arrow keys to change the height.
Answer:
This function (along with the main)is written using python progrmming language.
The function is written using for loop;
This program does not make use comments (See explanation section for detailed line by line explanation)
def is_prime(num):
if num == 1:
print(str(num)+" is not prime")
else:
for i in range(2 , num):
if num % i == 0:
print(str(num)+" is not prime because it can b divided by "+str(i)+" and "+str(int(num/i))+" with no remainder")
break;
else:
print(str(num) + " is prime because only 1 and "+str(num)+" divide it with no remainder")
num = int(input("Number: "))
is_prime(num)
Explanation:
This line defines the function is_prime
def is_prime(num):
The italicize line checks if the user input is 1; If yes it prints 1 is not prime
if num == 1:
print(str(num)+" is not prime")
If the above conditional statement is not true (i.e. if user input is greater than 1), the following is executed
else:
The italicized checks if user input is primer (by using for loop iteration which starts from 2 and ends at the input number)
for i in range(2 , num):
if num % i == 0:
This line prints if the number is not a prime number and why it's not a prime number
print(str(num)+" is not prime because it can b divided by "+str(i)+" and "+str(int(num/i))+" with no remainder")
break;
If otherwise; i.e if user input is prime, the following italicized statements are executed
else:
print(str(num) + " is prime because only 1 and "+str(num)+" divide it with no remainder")
The function ends here
The main begins here
num = int(input("Number: ")) This line prompts user for input
is_prime(num) This line calls the defined function
