Micronutrients are substances that do not give energy to the body but they are essential for the correct functioning of the body. Examples of micronutrients are Vitamins and Minerals.
If you need a function to get both the number of items and the cost per item from a user, which would be a good function declaration to use?
Answer:
double costAndNumItems (int numOfItems, double costPerItem){
return 0;
}
Explanation:
Above is how functions/methods are declared in Java programming language. We speficify the functions return type (double in this case), this is followed by the function's name costAndNumItems and then the arguments list which specifies the list of parameters that this function will accept. (numOfItems and costPerItem) followed by an open and close braces. Inside the braces is where the code for the functions behaviour is defined.
Zipoids is a level of currency used by obscure gamers. These gamers must pay tax in the following manner 0 - 5,000 zipoids – 0% tax 5001 - 10,000 zipoids – 10% tax 10,001 – 20,000 zipoid – 15% tax Above 20,000 zipoids 20% tax Write a program that will get the amount of Zipoids earned and will compute the tax. Your program should output the tax and the adjusted pay after the tax. You should use a ladder style if /else to compute this. Do not put cin or cout inside the if logic. Only compute the tax.
Answer:
C++
Explanation:
#include <iostream>
int main() {
int zipoids, tax = 0;
cout<<"Enter Zipoids earned: ";
cin>>zipoids;
// Compute tax
if ((zipoids > 5000) && (zipoids <= 10000))
tax = 10;
else if ((zipoids > 10000) && (zipoids <= 20000))
tax = 15;
else
tax = 20;
// Output tax
cout<<endl;
cout<<"Tax: "<<tax<<"%";
return 0;
}
To compute the adjusted pay, you need to have the original pay.
Hope this helps.
What is the decimal format of the binary IP address 11001110.00111010.10101010.01000011?
Answer:
206.58.170.67 is the decimal format of the given binary IP address.
Explanation:
we can convert the binary number into decimal by the following procedure.
11001110 = 1x2⁷+1x2⁶+0x2⁵+0x2⁴+1x2³+1x2²+1x2¹+0x2⁰
= 128 + 64 + 0 + 0 + 8 + 4 + 2 + 0
= 206
00111010 = 0x2⁷+0x2⁶+1x2⁵+ 1x2⁴+1x2³+0x2²+1x2¹+0x2⁰
= 0 + 0 + 32 + 16 + 8 + 0 + 2 + 0
= 58
10101010 = 1x2⁷+0x2⁶+1x2⁵+ 0x2⁴+1x2³+0x2²+1x2¹+0x2⁰
= 128 + 0 + 32 + 0 + 8 + 0 + 2 + 0
= 170
01000011 = 0x2⁷+ 1x2⁶+ 0x2⁵+ 0x2⁴+ 0x2³+0x2²+1x2¹+1x2⁰
= 0 + 64 + 0 + 0 + 0 + 0 + 2 + 1
= 67
so, the IP address is becomes 206.58.170.67

Write a program that takes as input a number of kilometers and prints the corresponding number of nautical miles. Use the following approximations: A kilometer represents 1/10,000 of the distance between the North Pole and the equator. There are 90 degrees, containing 60 minutes of arc each, between the North Pole and the equator. A nautical mile is 1 minute of an arc.
```python
def kilometers_to_nautical_miles(kilometers):
nautical_miles = kilometers * 0.0001 * 90 * 60
print(f"{kilometers} kilometers is approximately {nautical_miles} nautical miles.")
# Example usage:
kilometers_to_nautical_miles(100)
```
Explanation:In this program, we use the given approximations to convert kilometers to nautical miles. The first approximation states that a kilometer represents 1/10,000 of the distance between the North Pole and the equator. So, we multiply the input kilometers by 0.0001 to get the fraction of this distance.
Next, we consider that there are 90 degrees between the North Pole and the equator, and each degree contains 60 minutes of arc. Therefore, to convert degrees to minutes of arc, we multiply by 90 * 60. Combining these factors, we arrive at the conversion factor.
The formula used is: [tex]\[ \text{{Nautical Miles}} = \text{{Kilometers}} \times \left( \frac{1}{10,000} \times 90 \times 60 \right) \][/tex]
For example, if the input kilometers are 100, the calculation would be [tex]\(100 \times 0.0001 \times 90 \times 60\)[/tex] resulting in the approximate equivalent in nautical miles. The program then prints the input kilometers and the corresponding calculated nautical miles.
This program provides a straightforward and efficient way to perform the conversion while adhering to the given approximations and using a simple mathematical formula.
Which of the following are valid data definition statements that create an array of unsigned bytes containing decimal 10, 20, and 30, named myArray.
a. myArray BYTE 10, 20, 30
b. BYTE myArray 10, 20, 30
c. BYTE myArray[3]: 10, 20,30
d. myArray BYTE DUP (3) 10,20,30
Answer:
The answer is "Option a".
Explanation:
In the question it is defined, that an array "myArray" is defined, which contain the decimal 10, 20 and 30 unsigned bytes, and to assign these value first name of array is used, then the bytes keyword is used after then values, and other options were wrong that can be described as follows:
In option b and option c, The byte keyword firstly used, which is illegal, that's why it is wrong.In option d, In this code, DUP is used, which is not defined in question, that's why it is wrong.
In the following data definition, assume that List2 begins at offset 2000h. What is the offset of the third value (5)?
List2 WORD 3,4,5,6,7
a. 20008h
b. 2002h
c. 2000h
d. 2004h
Answer:
The offset of the third value (5) is 2004h
Explanation:
Offset is the distance from a starting point, either the start of a file or the start of a memory address.
The value is added to a base value to derive the actual offset value.
In the question above,
The base value = 3 because the item is at the 3rd position
Hence, the offset position = 3 + 1 = 4
Note that the offset begins at 2000
So, the offset value of 5 = 2000 + 4
Offset = 2004h
The offset of the third value (5) in the array List2, which begins at offset 2000h, is 2004h because each WORD value occupies 2 bytes, and the index of the third value is 2.
Explanation:The data definition given is for an array of WORD values starting at offset 2000h. In assembly language or low-level programming, a WORD typically represents a 16-bit (2-byte) value. Since the array starts at offset 2000h and each value in the array occupies 2 bytes, we can calculate the offset for each value by adding 2 times the index of the desired value (since indexing starts at 0) to the starting offset.
The third value in the array (which is the value 5) has an index of 2 (as we start counting from 0). Thus, the offset for the third value is computed as:
Starting offset + (Index of value * Size of each value)
2000h + (2 * 2) = 2000h + 4 = 2004h
Hence, the correct offset for the third value in the array is 2004h.

In Oracle, you can use the SQL Plus command show errors to help you diagnose errors found in PL/SQL blocks.a. Trueb. False
Answer:
The correct answer is letter "A": True.
Explanation:
SQL Plus commands are tools that allow users access to Oracle RDBM. Among its features, it is useful to startup and shutdown an Oracle database, connect to an Oracle database, enter SQL*Plus commands to set up the SQL Plus environment, and enter and execute SQL commands and PL/SQL blocks.
The statement is true. You can use the SQL Plus command 'show errors' in Oracle to diagnose syntax and runtime errors in PL/SQL blocks. Logical errors do not produce error messages and are harder to diagnose.
The statement is true. In Oracle, using the SQL Plus command show errors can help you diagnose errors found in PL/SQL blocks.
When you create or modify a PL/SQL block, it is compiled automatically, and any found compilation errors, be it syntax or runtime errors, can be displayed using the show errors command.
Logical errors, on the other hand, do not produce error messages and are usually more difficult to diagnose and solve because they depend on the correct logic and flow of the program rather than syntax or runtime constraints.
consider the following environment with a local dns caching resolver and a set of authoritative dns name servers
• the caching resolver cache is empty,
• TTL values for all records is 1 hour,
• RTT between stub resolvers (hosts A, B, and C) and the caching resolver is 20 ms,
• RTT between the caching resolver and any of the authoritative name servers is 150 ms
• There are no packet losses•All processing delays are 0 ms
Answer:
Normally in a DNS server, There are no packet losses•All processing delays are 0 ms
Explanation:
If any packet lost in DNS then lost in the connection information will be displayed in prompt. Once the packet is lost then data is lost. So if the packet is lost then data communications are lost or the receiver will receive data packet in a lost manner, it is useless.
To connect in windows normally it will take 90 ms for re-establish connection it normally delays the time in windows. So that end-user he or she for best performance ping the host or gateway in dos mode so that connection or communication will not be lost. If any packet is dropped DNS will get sent the packet from sender to receiver and the ping rate will more in the network traffics.

Assume that you have been hired by a small veterinary practice to help them prepare a contingency planning document. The practice has a small LAN with four computers and Internet access.
1. Prepare a list of threat categories and the associated business impact for each.
2. Identify preventive measures for each type of threat category.
3. Include at least one major disaster in the plan.
Answer:
Answer explained below
Explanation:
Given: The information provided is given as follows:
There is a small veterinary practice which includes the services like office visits, surgery, hospitalization and boarding. The clinic only has a small LAN, four computers and internet access. The clinic only accepts cats and dogs. Hurricanes are the major threatening factor in the geographical region where the clinic is located. The clinic is established in a one-story building with no windows and meet all the codes related to hurricanes. As public shelters do not allow animals to stay when there is a possibility of hurricanes, therefore the clinic does not accept animals for boarding during that time
Contingency planning documents for the tasks given is as follows:
Threat category along with their business impact: Hurricane: It is given that the region where the clinic is located is highly threatened by hurricanes. This type of disaster can affect the life of the employees as well as patients present in the building. Also, in case of a strong hurricane, the building can also be damaged. Preventive measures: Separate shelters can be installed for animals in case of emergency.
Fire: In case of fire due to malfunctioning of any electrical equipment or any other reason, there is no window or emergency exit available. It can damage the building and the life of the employees and animals will be in danger. Preventive measures: Services should be provided to all the electrical equipment’s from time to time and emergency exits should be constructed so that there is a way to get out of the building in case the main entrance is blocked due to any reason in the time of emergency.
Viral Influenza: If an employee or animal is suffering from any serious viral disease. That viral infection can easily spread to others and make other animals as well as employees sick. If the employees working in the clinic are sick. This will highly affect the efficiency of them which will then affect the business. Preventive measures: This can be avoided by giving necessary vaccines to the employees from time to time and taking care of the hygiene of the patient as well as the clinic which will make the chance of infection to spread low. Flood: In case of a flood like situation, as given the building has only one story and there is no emergency exit for employees and animals to escape. This can put the life of the employees and animals in danger and can affect the working of the clinic as well. Preventive measures: This can be prevented by collecting funds and increasing the story’s in the building or constructing alternate site location so that in case of emergency, the animals or employees can be shifted to other locations.
Final answer:
To prepare a contingency planning document for a veterinary practice, you should identify threat categories such as user actions, natural disasters, equipment failure, and major disasters. For each threat, assess business impacts and identify preventive measures like user access control, data backups, and emergency action plans.
Explanation:
Contingency Planning for Veterinary Practice
To assist a small veterinary practice with contingency planning, identifying potential threats and their impact on the business is essential. Here is a summarized approach to address the practice’s needs:
1. Threat Categories and Business Impact
User Actions (malicious/accidental) - These can result in data breaches or data loss, impacting client confidentiality and business operations.
Natural or Man-Made Disasters - Examples include floods or fires which can destroy equipment and data, leading to significant downtime and financial loss.
Equipment Failure - This could be due to power surges or general malfunctions, causing disruption of services and loss of productivity.
Major Disaster (such as chemical release) - Requires an immediate evacuation and can result in extended closure, affecting both client service and revenue.
2. Preventive Measures
Establish strict user access controls and train employees on data security to prevent unauthorized access or misuse.
Implement regular backups and store them offsite to mitigate data loss from equipment failure and disasters.
Install surge protectors and maintain equipment to prevent failures from power issues.
Develop an emergency action plan, including evacuation procedures, to ensure safety and quick resumption of operations in case of a major disaster.
3. Major Disaster Planning
A major disaster such as a flood or chemical spill would need a detailed emergency action plan, with specific focus on evacuation routes, employee safety protocols, and communication plans to stay in touch with clients and authorities.
By anticipating these scenarios, the veterinary practice can create a robust contingency plan that minimizes the impact of each threat and ensures a timely and effective response.
In order to recover from an attack on any one server, it would take an estimated 14 hours to rebuild servers 1, 2, 3, and 4 and 37 hours to rebuild server 5. If each server is required to be online 8,760 hours a year, compute the EF for each server.
Answer:
It is an approximate time to rebuild servers to satisfy either ourselves or management.
Explanation:
To rebuild the server all depends on CPU and process time taken by each individual server time taken.
Some servers to rebuild will take less time because the effected server is very less moreover some patches have to download from the internet and if downloading speed is very less then it will be a delay on the rebuild or recovering process. Suppose internet downloading speed fast enough but internal data operation speed is very low profile than their will in the delay to rebuild the servers.
Best practice method to restore from the last backup so the delay time to rebuild the server is known.
"Simon Says" is a memory game where "Simon" outputs a sequence of 10 characters (R, G, B, Y) and the user must repeat the sequence. Create a for loop that compares the two strings starting from index 0. For each match, add one point to userScore. Upon a mismatch, exit the loop using a break statement
Answer:
String simonSays = "ABCDEFGHIJ";
System.out.println("Simon says: " + simonSays);
int userScore = 0;
System.out.print("Make your guess: ");
Scanner obj = new Scanner(System.in);
String guess = obj.next();
for(int i=0; i<10; i++){
if(guess.charAt(i) != simonSays.charAt(i)){
break;
}
else{
userScore++;
}
}
System.out.println("Your score is " + userScore);
Explanation:
Even though programming language is not specified, variable userScore implies that it should be in Java. Also, note that this code should be in your main function.
- simonSays variable is created to hold what Simon says and it is printed out.
- userScore variable is created to track user's score.
- guess variable takes the input written by the user. (I assumed users enter their choice. Otherwise, you should delete the Scanner part and just create another variable like String guess = "ABDFFHHH" )
- Then, we need to check if the user input is same as what Simon says using for loop. (Note that the loop is iterated 10 times because it is known Simon says 10 characters). if(guess.charAt(i) != simonSays.charAt(i), charAt(i) method is used to check each of the characters.
- If the characters are not same, the loop is terminated.
- If characters are same, userScore is increased by 1.
- After comparing all the characters, userScore is printed.
Which line in the following program will cause a compiler error? 1 #include 2 using namespace std; 3 4 int main() 5 { 6 int number = 5; 7 8 if (number >= 0 && <= 100) 9 cout << "passed.\n"; 10 else 11 cout << "failed.\n"; 12 return 0; 13 }
Answer:
Line 8 gives a compiller Error
Explanation:
In line 8, the statement: if (number >= 0 && <= 100) will give a compiller error because when using the logical and (&&) It is required to state the same variable at both sides of the operator. The correct statement would be
if (number >= 0 && number <= 100). The complete corrected code is given below and it will display the output "passed"
#include <iostream>
using namespace std;
int main()
{
int number = 5;
if (number >= 0 && number <= 100)
cout << "passed.\n";
else
cout << "failed.\n";
return 0;

Write a program that prompts the user to input the number of quarters, dimes, and nickels. The program then outputs the total value of the coins in pennies.
Final answer:
The question asks for a program to calculate the total value in pennies of a given number of quarters, dimes, and nickels, with a solution presented in Python.
Explanation:
Each quarter is worth 25 pennies, each dime is worth 10 pennies, and each nickel is worth 5 pennies. To calculate the total value, you multiply the number of each type of coin by its value in pennies and sum up these values.
For example, if a user inputs 3 quarters, 2 dimes, and 1 nickel, the program will calculate the total value as (3 * 25) + (2 * 10) + (1 * 5) = 95 pennies.Sample Python code:
quarters = int(input('Enter the number of quarters: '))Write a class for a Cat that is a subclass of Pet. In addition to a name and owner, a cat will have a breed and will say "meow" when it speaks. Additionally, a Cat is able to purr (print out "Purring..." to the console).

Open a command prompt on PC1. Issue the command to display the IPv6 settings. Based on the output, would you expect PC1 to be able to communicate with all interfaces on the router ?
Answer:
yes it can communicate with all interfaces on the router.
Explanation:
PC1 has the right default gateway and is using the link-local address on R1. All connected networks are on the routing table.
Netsh may be a Windows command wont to display and modify the network configuration of a currently running local or remote computer. These activities will tell you in how manny ways we can use the netsh command to configure IPv6 settings.
To use this command :
1. Open prompt .
2. Use ipconfig to display IP address information. Observe the output whether IPv6 is enabled, you ought to see one or more IPv6 addresses. A typical Windows 7 computer features a Link-local IPv6 Address, an ISATAP tunnel adapter with media disconnected, and a Teredo tunnel adapter. Link-local addresses begin with fe80::/10. ISATAP addresses are specific link-local addresses.
3. Type netsh interface ipv6 show interfaces and press Enter. note the output listing the interfaces on which IPv6 is enabled. Note that each one netsh parameters could also be abbreviated, as long because the abbreviation may be a unique parameter. netsh interface ipv6 show interfaces could also be entered as netsh ipv6 sh i.
4. Type netsh interface ipv6 show addresses Observe the results of the interface IPv6 addresses.
5. Type netsh interface ipv6 show destinationcache and press Enter. Observe the output of recent IPv6 destinations.
6. Type netsh interface ipv6 show dnsservers and press Enter. Observe the results listing IPv6 DNS server settings.
7. Type netsh interface ipv6 show neighbors and press Enter. Observe the results listing IPv6 neighbors. this is often almost like the IPv4 ARP cache.
8. Type netsh interface ipv6 show route and press Enter. Observe the results listing IPv6 route information.
Consider the method total below:
public static int total (int result, int a, int b){ if (a == 0) { if (b == 0) { return result * 2; } return result / 2; } else { return result * 3; }}
The assignment statementx = total (1, 1, 1);must result in:A. x being assigned the value 3 B. x being assigned the value 7C. x being assigned the value 5D. x being assigned the value 2E. x being assigned the value 0
Answer:
Explanation:
When you look at the assignment "x = total (1, 1, 1);", you can see that result, a and b all refers to 1. Then, you need to go to the function and check the conditions. The first condition is "if (a == 0)", it is not true because a is assigned to 1. Since that is not true, you need to go to the else part "else { return result * 3". That means the result of this function is going to give us 3 (because result variable equals to 1 initially). That is why x is going to be assigned as 3.
Using the CelsiusToKelvin function as a guide, create a new function, changing the name to KelvinToCelsius, and modifying the function accordingly.
#include
double CelsiusToKelvin(double valueCelsius) {
double valueKelvin = 0.0;
valueKelvin = valueCelsius + 273.15;
return valueKelvin;
}
int main(void) {
double valueC = 0.0;
double valueK = 0.0;
valueC = 10.0;
printf("%lf C is %lf K\n", valueC, CelsiusToKelvin(valueC));
valueK = 283.15;
printf("%lf is %lf C\n", valueK, KelvinToCelsius(valueK));
return 0;
}
The celsiusToKelvin method as a guide checks the Java code given below.
Now, to create a new method, change the name to kelvinToCelsius, and modify the method accordingly, using the celsiusToKelvin method as a guide check the Java code given below.
Hence, //JAVA CODE//
import java. util.Scanner;
public class TemperatureConversion {
public static double celsiusToKelvin(double valueCelsius) {
double valueKelvin;
valueKelvin = valueCelsius + 273.15;
return valueKelvin;
}
public static double kelvinToCelsius(double valueKelvin) {
double valueCelsius;
valueCelsius = valueKelvin - 273.15;
return valueCelsius;
}
public static void main (String [] args) {
Scanner scnr = new Scanner(System.in);
double valueC;
double valueK;
valueC = 10.0;
System.out.println(valueC + " C is " + celsiusToKelvin(valueC) + " K");
valueK = scnr.nextDouble();
System.out.println(valueK + " is " + kelvinToCelsius(valueK) + " C");
}
}
Output:
10.000000 C is 283.150000 K
283.150000 is 10.000000 C

In this warm up project, you are asked to write a C++ program proj1.cpp that lets the user or the computer play a guessing game. The computer randomly picks a number in between 1 and 100, and then for each guess the user or computer makes, the computer informs the user whether the guess was too high or too low. The program should start a new guessing game when the correct number is selected to end this run (see the sample run below).
Check this example and see how to use functions srand(), time() and rand() to generate the random number by computer.
Example of generating and using random numbers:
#include
#include // srand and rand functions
#include // time function
using namespace std;
int main()
{
const int C = 10;
int x;
srand(unsigned(time(NULL))); // set different seeds to make sure each run of this program will generate different random numbers
x = ( rand() % C);
cout << x << endl;
x = ( rand() % C ); // generate a random integer between 0 and C-1
cout << x << endl;
return 0;
}
Answer:
#include <iostream>
#include <time.h>
using namespace std;
int main()
{
// Sets the random() seed to a relatively random number
srand(time(0));
// Variables are defined
int RandomNumber = rand() % 100 + 1, UserSelection, Tries = 5;
// Gets a number from the user
cout << " Guess a number between 1 and 100, you have five tries to find the correct number.\n :";
cin >> UserSelection;
// Prevents the user from selecting a number out of bounds
while (UserSelection > 100 || UserSelection < 1)
{
cout << " I said between 1 and 100. select a new number BETWEEN 1 AND 100!\n :";
cin >> UserSelection;
}
// Stuck in while till they guess right, or run out of tries
while (UserSelection != RandomNumber)
{
// kicks user from the loop when they run out of tries
Tries -= 1;
if (Tries == 0)
{
break;
}
// Tells the user they got the wrong number and how many tries they have left
cout << " The Number was not correct, you have " << Tries << " more Guess(es) left.";
// Tells the user if they are above the number
if (UserSelection > RandomNumber)
{
cout << " Try guessing a little lower\n :";
}
// Tells the user if they are bellow the number
else if (UserSelection < RandomNumber)
{
cout << " Try guessing a little higher\n :";
}
// User input if the number is wrong they stay in the loop, if they are right they fail the condition for the loop and get dialogue according to how many tries they have left
cin >> UserSelection;
// Prevents the user from selecting a number out of bounds
// If the number is greater than 100 or less than 1 they are prompted to select a new number
while (UserSelection > 100 || UserSelection < 1)
{
cout << " I said between 1 and 100. select a new number BETWEEN 1 AND 100!\n :";
cin >> UserSelection;
}
}
// The amount of tries the user has left determines what dialogue they get
// First try win
if (Tries == 5)
{
cout << " That's not luck, that's skill. you got the number right on the first try.\n ";
system("pause");
}
// Second try win
else if (Tries == 4)
{
cout << " That's pretty good luck, you guessed it right on the second try.\n ";
system("pause");
}
// Third try win
else if (Tries == 3)
{
cout << " Could be better, but it could also be way worse. You got it right on the third try.\n ";
system("pause");
}
// Fourth try win
else if (Tries == 2)
{
cout << " Could be worse, but it could also be a lot better. You got it right on your fourth try.\n ";
system("pause");
}
// Fifth try win
else if (Tries == 1)
{
cout << " I hope you don't gamble much. You got it right on your last guess.\n ";
system("pause");
}
// Losing dialogue
else
{
cout << " You guessed wrong all five times, the right number was " << RandomNumber << "\n ";
system("pause");
}
return 0;
}
Explanation
C++, console based guessing game.
Int Tries at the top of main is linked to how many tries the user has

Use set builder notation to describe these sets.
a) S1 = {1, 2, 4, 8, 16,...}
b) S2 = {2, 5, 8, 11, 14,...}
c) S3 = {1, 4, 9, 16, 25,...}
d) S4 = {a,b,c,d,e, f ,..., z}
e) S5 = {a,e,i,o,u}
Answer:
a) S1 = { 2^x | x belongs to the set of Whole Numbers}
b) S2 = { 2+3(x-1) | x belongs to Natural Numbers }
c) S3 = { x^2 | x belongs to the set of Natural Numbers }
d) S4 = { x | x belongs to English Alphabet }
e) S5 = { x | x is a Vowel of English Alphabet}
Explanation:
Whole Numbers = {0, 1, 2, 3, ...}
Natural Numbers = {1, 2, 3, ...}
English Alphabet={a, b, c, d, e, ... , x, y, z }
Vowels of English Alphabet = {a, e, i, o, u}
In general, it is good practice to make your security policies relevant to business needs ____ because they stand a better chance of being followed.
True. It is good practice to make your security policies relevant to business needs because they stand a better chance of being followed
Further explanation:
Employee error in recent years has risen to an all-time high as the most common cause of online security breach. It is for this reason that security policies relevant to business needs need to be put in place. To ensure employees are not putting your business at risk, the employer needs to set clear security policies that need to be followed. Let these policies align with business needs and include things like employees should use the internet for the intended purpose and avoid non-business related sites.

In which type of modulation is a 1 distinguished from a 0 by shifting the direction in whichthe wave begins?
a.bandwidth modulation
b.amplitude modulation
c.frequency modulation
d.phase modulation
e.codec modulation
Answer:
E. Codec modulation
Explanation:
Codec is used to encode digital signals for transmission.
Amplitude modulation uses the amplitude of the carrier wave to encode or modulate the information for transmission.
The phase of a wave changes with respect to the amplitude, so information is modulated with the phase angle as amplitude changes in phase modulation.
Bandwidth modulation is a form of modulation that encode the information of a fixed bit size based on the frequency of the carrier wave. It is similar to frequency modulation, but frequency modulation modulate a signal wave information.
Phase modulation is a type of modulation where one (1) is distinguished from zero (0) by shifting the direction in which the wave begins (Option d).
Analog transmission refers to a methodology of transmission that transmits information by a continuous signal, which can vary in amplitude, phase, and other characteristics related to the proportion of such information.Phase modulation is a pattern used for conditioning communication signals and then for the transmission of that signals.This type of modulation (phase modulation) employs variations in phase and amplitude for carrying out the modulation and it is used for analog transmission.In conclusion, phase modulation is a type of modulation where one (1) is distinguished from zero (0) by shifting the direction in which the wave begins (Option d).
