Answer:
Option (B) is the correct answer to the following question.
Explanation:
Here, in the code "const" is the constant keyword which is used when we need that the value stored in that variable will never change.
The following option is correct because the assignment operator are those operator which initialize the value in the variable and overloading of the assignment operator would be as we use the other operators and also we could use them by creating the objects as we use in the copy constructor.
So, that's why the following option is correct.
An easy way to remember the difference between encoding and decoding within the communication process is to think of encoding as the message the sender intends to say, whereas decoding can be thought of as what the receiver actually ______.
Answer:
An easy way to remember the difference between encoding and decoding within the communication process is to think of encoding as the message the sender intends to say, whereas decoding can be thought of as what the receiver actually hears.
Explanation:
Encoding and decoding are the terms used in communication.Encoding can be defined as the process or way in which the message you want to convey is created. This means the words we expel to demonstrate that what we want to say are known as encoding. Decoding on the other hand involves the interpreting of the message. It means, understanding the message that has been sent is known as decoding.As communication process have two members say sender and receiver, so sender is associated with encoding and receiver with decoding.i hope it will help you!
Which line in the following program contains the header for the showDub function? 1 #include 2 using namespace std; 3 4 void showDub(int); 5 6 int main() 7 { 8 int x = 2; 9 10 showDub(x); 11 cout << x << endl; 12 return 0; 13 } 14 15 void showDub(int num) 16 { 17 cout << (num * 2) << endl; 18 } 1. 4 2. 6 3. 10 4. 1
The header for the showDub function is contained in line 4.
The header of a function in C++ is the first line where the function is declared before it is defined or called. It specifies the return type, the name of the function, and the parameters the function will take, if any. In this case, line 4, 'void showDub(int);' is where the function showDub is declared, making it the function's header. This is a forward declaration and tells the compiler what the function looks like. This allows the function to be called before it is fully defined, as seen in line 10 within the main function. The actual definition of the showDub function does not occur until line 15, where the function's operations are fully described.

You have a small wireless network that uses multiple access points. The network uses WPA and broadcasts the SSID. WPA2 is not supported by the wireless access points.
You want to connect a laptop computer to the wireless network. Which of the following parameters will you need to configure on the laptop? (Select two.)
a) AES encryption
b) TKIP encryption
c) Channel
d) BSSID
e) Preshared key
Answer:
b) TKIP encryption,e) Preshared key
Explanation:
The parameters that need to be configured on the laptop include the Temporal Key Integrity Protocol (TKIP) and the Preshared key. TKIP is an older wireless protocol that encrypts data at bit level. It is less secure as compared to the Advanced Encryption Standard (AES), AES works well with WPA2 which is not supported by the access point. The preshared key is the access password used on a shared secure channel. It is also used to validate users on the WiFi network. Once the two parameters are configured the laptop will have access to the network
To connect a laptop to a WPA wireless network, configure TKIP encryption and enter the preshared key. AES is used with WPA2 and is not applicable here, while the channel and BSSID are generally managed automatically.
Explanation:When connecting a laptop computer to a wireless network that uses WPA and broadcasts the SSID but does not support WPA2, you will need to configure certain parameters on the laptop. Since the network uses WPA, the compatible encryption that should be set up on the laptop is TKIP encryption since AES is typically used with WPA2. Additionally, you will need to enter the preshared key, which is a secret password or passphrase used to authenticate devices and grant access to the wireless network. Channels and BSSIDs are generally managed by the access points and are not typically configured manually on client devices unless troubleshooting specific connection issues or optimizing the network.
Which of the following statements about constructors are true? Check all that apply.
a.A constructor is the code that is called when you use the 'new' keyword.
b.A constructor is declared without a return type.
Answer:
a. Partly True
b. True
Explanation:
(a) "new" keyword or syntax is used for the constructors while working in Perl and Moose object system for Perl.
For Visual Basics .Net, keyword "New" is used
For Python, "___new___" is used which allocates memory for instance and receives class as an argument.
For Objective-C, "alloc" and "init" are used for constructor method. "alloc" allocates memory for the instance and "init" handles the bulk of initializing the instance. Whereas, the "new" keyword calls both "alloc" and "init" for class instance.
(b) A constructor does not return any value because it is called by the memory allocation and object initialization code in the runtime and not directly by your code.
The process of recording an actor’s movement digitally for the purpose of animating a digital character in a movie is called Realistic Animation Motion Capture CGI (Computer Generated Imagery) Performance Animation
Answer:
It is called Motion Capture.
Explanation:
Motion capture it's a widely used technology that allows us to record (or capture) the movements of a real person, and convert them to a digital environment.
It can be used in the development of video games when facial expressions or realistic movements are needed to bring fictional characters to life, motion sensors are used on a real person, and the person displays the necessary emotions, movements or expressions that are later digitally adapted to the 3D character.
Motion capture was one of the main techniques used to bring the famous Thanos, the famous Avenger's villain to life. Josh Brolin, the actor, would perform almost every scene wearing a specialized suit to capture the movements and facial expressions that were introduced to the 3D rendered Thanos model.

You have just received a call from a user who can't log on because she forgot her password. After you change her password, which of the password options listed would you set in the user's account so that she will have to change the password when she logs on using the password you assigned. True or False?
The above given question is incomplete as it does not contains the options that must be listed. Following are the options given for the above question:
a.
Password never expires.
b.
User cannot change password.
c.
User must change password at next logon.
d.
Account is disabled.
Answer:
Option c. User must change password at next logon.
is the correct answer.
Explanation:
In the password policy for different applications, it is the common practice that whenever the user can't access his/her account due to forgetting the password or due to hacking of its account, they are provided with the password by the network administrator so that they my log on to their profiles.
Now when the user will be notified of the new password that is changed by the administrator she must change her password at next logon so that she may secure the account and remember the new password created by herself for further logons.

Which of the following is a correct method header for receiving a two-dimensional array as an argument?A.public static void passArray(int[1,2])B.public static void passArray(int [ ][ ])C.public static void passArray(int[1],[2])D.public static void passArray(in[ ], int[ ])
Answer:
The correct option for this question is "B".
Explanation:
An Array is a collection of the homogenous(same type) elements. In the programming language, the correct way to pass two-dimensional array in function as an argument is option "B" and other options are not correct that can be described as:
In option, A It is a one-dimensional array but it is not a correct way to pass array in an argument like this. In option, C It is a two-dimensional array but in this array, we do not pass any number. In option, D it is not a two-dimensional array.That's why the answer to this question is option "B".
Final answer:
The correct method header for receiving a two-dimensional array in Java is 'public static void passArray(int [][])', which allows a method to accept a 2D array as its parameter.
Explanation:
The correct method header for receiving a two-dimensional array as an argument in Java is option B: public static void passArray(int [][]). This syntax is used to denote that the method takes a two-dimensional array of integers as its parameter. You use two sets of square brackets to indicate that the array is two-dimensional. The other options are either syntactically incorrect or do not properly represent a two-dimensional array.
Remember that ""state space"" refers to the space of all potential possibilities. Which dichotomous questions below will successfully narrow down the entire state space of ""flipping a coin and rolling a normal six-sided die"" to 1 or fewer possible outcomes regardless of the answers given?
Answer:
Please check options are not given. Please check explanation for corrected version.
Explanation:
Options are not mentioned. Please post the complete question.
However, if "below" is removed, the question makes sense. I am taking it that way.
Dichotomous question means those questions which has two outcomes: true or false.
For the given condition, this is possible only if:
coin shows head and dice shows 1coin shows head and dice shows 2head, 3head, 4head, 5head, 6tails, and all above casesHowever, each time, each mentioned condition should be strictly followed.
And fewer outcome than 1 is virtually or realistically impossible, as both coin and dice will roll out one outcome in any condition certainly.
A programmer is writing a system that is intended to be able to store large amounts of personal data. As the programmer develops the data system, which of the following is LEAST likely to impact the programmer's choices in designing the structure of the system?
A. Maintaining privacy of the information stored in the data set. B. Scalability of the system. C. Structuring the metadata of the information for analysis. D. The frequency of a particular item occurring in a data set.
Answer:
D.
Explanation:
Based on the information provided within the one choice that will least likely impact the programmer's choice in design would be the frequency of a particular item occurring in a data set. This is because the system needs to be handle a large amount of data and be able to scale accordingly, regardless of how many frequent a particular item occurs.
What does the following program do?
import turtle
def main():
turtle.hideturtle()
square(100,0,50,'blue')
def square(x, y, width, color):
turtle.penup()
turtle.goto(x, y)
turtle.fillcolor(color)
turtle.pendown()
turtle.begin_fill()
for count in range(2):
turtle.forward(width)
turtle.left(90)
turtle.end_fill()
main()
It draws 2 blue lines.
A) It draws a blue square at coordinates (100, 0), 50 pixels wide, starting at the top right.B) It draws a blue square at coordinates (0, 50), 100 pixels wide, starting at the top right.C) It draws a blue square at coordinates (100, 0), 50 pixels wide, in the lower-left corner.D) Nothing since you cannot call a function with turtle graphics corner
Answer:
C
Explanation:
It draws the blue square at coordinates (100,0) 50 pixel wide, and in the lower-left corner. You should know that the lower-left corner of the square should be at position x, y. Hence, the answer.
And this is true for any shape that you draw using turtle graphics in Python.
You should also know the function format of python, and how it is defined, declared and called. The penup command tells the turtle to not show what is drawn, or hide the ink. The pen down is just opposite to this.
The count is an inbuilt function that counts and can be used as above with range to create a for the look. forward moves the cursor according to width mentioned.
See how to pen down is called before beginning fill. And how we move to x,y using go to, and how the penup is used to hide ink while fill color is in effect, and we move to x,y.
End fill ends the process.

If userA sends a secure message to userB using an asymmetric cryptographic algorithm, and userB sends a reply, what key is used if userA wants another user, userC to read the reply message
Answer:
The answer is Symmetric Key cryptography
Explanation:
Because this method of encryption allow both parties to use the same key and cipher to encode and decode the ciphertext.
Answer:The
The answer is User Cs uses the Public Key.
Explanation:
Public-key cryptography refers to a cryptographic system that uses pairs of keys: one that is a private keys,which are seen only by the use and public keys, which may be used widely by different users.
The generation of such keys depends on algorithms that are cryptographic based on mathematical problems to provide function that is one way. A strong security only needs keeping the private key private; the public key can be openly distributed among users without compromising security.
When BranchCache is being utilized in an office and a client computer makes a subsequent request for a file, what will indicate to the client where the file can be retrieved from the cache in the branch office?
A. encrypted fileB. content informationC. original informationD. cached file
Answer:
Content Information
Explanation:
Client is the end user that required only information that is related to his desire. To access this information, the client request for the desired information. In response to the client request, relevant information that is required to the client is provided. This information is also called content information.
This the information that is provided to the end users only. In mentioned case client is the end user so branch cache will provided him only information about content.
A TCP connection has reached a steady state and transmits data at a constant rate. List as many factors as you can that determine the transmission rate reached by the connection? Include the application and the operating system on both ends of the connection in your consideration.
TCP connection:
Once TCP connections reached steady state that makes end user that connectivity is stable. But end user has to do analysis the pinging time ready. for example in operating system command prompt mode ends user have to ping designation tcpip address.
Computer A
In command prompt mode end user try ping 10.10.10.10 –t (i.e. Computer B tcpip Address). End user tries to ping destination tcpip address if result comes in milliseconds then it is good connectivity rate.
Same away
Computer B
In command prompt mode end user try ping 10.10.10.20 –t (i.e. Computer A tcpip Address). End user tries to ping destination tcpip address if result comes in milliseconds then it is good connectivity rate.
End user can also check by executing TRACERT commands on designation tcpip address. End user can find how the flow of network packets travels.
You have just connected a brand new workstation to your local network. As per company policy, you have used a static IP configuration. However, all attempts to reach the Internet from the workstation fail. You have verified that you can communicate with servers and other workstations on the local network, and that you are the only one having an issue reaching the Internet. What is most likely the issue?
IP addresses are unique codes identifying devices on a network broken down into Network ID and Host ID.
IP Address: An IP (Internet Protocol) address is a unique code that identifies a piece of equipment connected to a network. These addresses are used in messages between network devices like the network or wireless card in your computer and the equipment from your ISP. Each IP address can be broken down into the Network ID and Host ID.
Ensuring the uninterrupted flow of information' describes which key communications and information systems principle?
A. Security
B. Reliability, Scalability, and Portability
C. Resilience and Redundancy
D. Interoperability
Answer: C) Resilience and Redundancy
Explanation:
According to the principle of communication and information system , redundancy is the factor that maintains the continuous flow of message or data even when failure is experienced in network by adding alternate or extra component in infrastructure for support.Resilience is the factors that helps network to persist even in the state of faults by keeping the main function working and recovering the fault to maintain the flow of data.Other options are incorrect because security is protection of data. Reliability factor means dependency , scalibility is changing scale of network and portability is changing position of components. Interoperability is exchanging information with devices and making use of it.Thus, the correct option is option(C).
Answer:
C. Resilience and Redundancy
Explanation:
Robust systems are characterized by having the ability to maintain their essential performance conditions despite receiving disturbances or noise. Robustness is the ability of a system to absorb stress and continue functioning, particularly when the system is subjected to unpredictable variations in its scope of performance.
The redundancy, consisting of the duplication of the critical components of a system, is developed with the purpose of granting robustness to the systems, so that in the event of the failure of a component that could jeopardize the main task or objective of the system, there is an alternative capable of replacing the system that suffers from a failure.
Robustness or resilience is characterized by two important aspects, the first is resistance to change or flexibility that is expressed as the ability of a system to resist a disturbance without undergoing irreversible change and the second is the ability of a system to recover.

C. ODBC
D. OEC
Answer: (C) ODBC
Explanation:
ODBC stand for the open database connectivity and it is one of the industry standard protocol in which the ODBC driver uses the interface for access the data in the DBMS (Database management system).
The open system connectivity uses the structure query language standard for accessing the given information or data. The main aim of the ODBC is that it makes the independent operating system, software and also various types of database system. In the open system connectivity, we can easily exchange data and also interact with the different types of vendors.Therefore, Option (C) is correct.
The variety of theatre introduced in the 1960s that denotes semi-professional or even amateur theatre in the New York/Manhattan area, often in locations such as church basements, YMCAs, and coffeehouses, is commonly known as off-off-Broadway.
a. True.
b. False.
Answer:
Option a. True
Explanation:
The given statement is true because the off-off-Broadway was a movement started from 1958. It can be discussed as:
(Amateur theater ) that rejected all other commercial theaters.Most of the off-off-Broadways were made in 1960's in coffee shops of New York.Stage plays were performed experimentally without taking a notice on the playwrights and actors.During Integration, the experimental work was of great value and was known for its nature.Gradually the image of Broadway got down while reshaping itself and the produced works were no longer suitable for commercial theaters. Many of the plays from these theaters are still known such as:The Dove CompanyThe old reliableLa Mamai hope it will help you!
When you code an UPDATE statement for one or more rows, the SET clause names the columns to be updated and the values to be assigned to those columns, and the ______________________ clause specifies the conditions a row must meet to be updated.
Answer:
the Where clause specifies the conditions a row must meet to be updated.
Explanation:
UPDATE statement is used to update existing records in a database table. The syntax is as follows:
UPDATE table
SET column1 = expression1,
column2 = expression2,
...
[WHERE conditions];
SET clause names the columns to be updated and the values to be assigned to those columnsWHERE clause specifies the conditions a row must meet to be updatedGiven an int variable n that has already been declared and initialized to a positive value , use a while loop to print a single line consisting of n asterisks. Use no variables other than n.
Final answer:
To print a line of n asterisks with a while loop using only the variable n, a loop would run to print an asterisk and decrement n by one until n reaches zero, without using additional variables.
Explanation:
To print a single line consisting of n asterisks using a while loop in a programming language without using any variables other than n, which has already been initialized to a positive value, you could use the following pseudocode:
while (n > 0) {
print("*");
n = n - 1;
}
This pseudocode highlights the use of a while loop to print asterisks. The loop continues to run as long as n is greater than zero, printing an asterisk and then decrementing n by one on each iteration. There is no need for additional variables; we are only manipulating the value of n within the loop.
In actual code, depending on the programming language you are using, you might use a function like print() or System.out.print() to print each asterisk without a newline character, allowing them to be printed on the same line.
