Answer:

The correct option is: B. Spoofing

Explanation:

In network security, a spoofing attack is defined as a technique by which an individual or a program impersonates as another by deliberately falsifying information or data to spread malware, steal information, or bypass access controls. The common types of spoofing are email spoofing, IP spoofing, DNS spoofing.

• What advantage does a circuit-switched network have over a packet-switched network? What advantages does TDM have over FDM in
lions [1.4K]

Answer:

Advantages of both circuit switched networks and TDM are given below:

Explanation:

Advantages of circuit switched network over packet switched network:

  • Circuit switched network has the advantage of being physically connected and having a dedicated channel for communication between the sender and the receiver which also makes it more reliable. Packet switched networks do not have a dedicated channel hence, they are not that reliable.
  • Circuit switched networks are used for voice calls because there is no timing jitter or delay in these types of networks while packet switched networks do not offer this advantage.

Advantages of TDM over FDM in a circuit switched network:

  • TDM is time division multiplexing i.e. multiple information is sent in different time intervals but on the same frequency. While FDM sends information using different frequencies. So, the advantage of using TDM is that the information will be sent from the sender to the receiver using only a single frequency.
  • Using TDM, bandwidth is saved because it only sends information on a single frequency unlike FDM.
  • In TDM, there is low chance of interference between signals since they are sent in different time intervals from the sender to the receiver. While FDM has a higher chance of interference.

What output is produced by the following code? Integer first = new Integer(7); Integer second = first; if (first == second) Syst
fenix001 [56]

Answer:

The correct output of this question is  "Sneezy Sleepy".

Explanation:

In the given code firstly we create the object of the integer class that is first in this we pass the integer value that is 7. Then we declare another second integer variable is this variable we pass object as a reference. Then we use the two conditional statements. In the first, if block we check that the object of the class is equal to the reference variable. If it is true it prints Sneezy. otherwise, it will print Grumpy. In second if block we check that the object of the class is equal to the reference variable. but in this time we the equals() function it is the same as(==). If the condition is true it prints Sleepy. otherwise, it will print Doc. So the output of the code is Sneezy Sleepy.

A Python data model defining the state of a game for Tic-Tac-Toe. You must fully describe the notion of a state of the game, lim
Artist 52 [7]

Answer:

Check the explanation

Explanation:

Here in this game of Tic-Tac-Toe, it is using the TPGE engine which is a Tiny Python Game Engine. Let's talk about its functions like:-

def image_type(img): In this function, it is simply taking image as a parameter and returning its object type like DISC if the image is in graphical form, TEXT if it is a string, and LINE if it is other than the mentioned object.

def convert_image(img):  In this function, it is simply taking image as a parameter and returning an equivalent graphical object as understood by John Zelle's. Mainly comparing for three things in this function and those are: if image equals to DISC then it is calling convert_circle(function), if image equals to LINE then it is calling convert_line(function), and if image equals to TEXT then it is calling convert_text(function),

def convert_circle(x): This function takes a list( a group of values) and makes a circle at the center of the window and the circle's radius is coming from the list.

convert_text, convert_line, convert_circle are only creating text, line, and circle and then returning it.

def graphical_elements(images): This function is taking image as a parameter and then extracting shape and color from the image and then calling convert_image(shape) and convert_type(shape) and it gives us graphic and kind respectively. Now it is checking whether kind equals to DISC If yes then filling color on the window else, setting the outline of the window

def run(): Here it is finally running the game with required parameters, the whole game is continously running under the while loop.

That's all
