What is contained in the trailer of a data-link frame?

Answers

Answer 1

Answer:

Trailer: It contains the error detection and error correction bits. It is also called a Frame Check Sequence (FCS).

Explanation:

Answer 2

In the context of data-link frames, the trailer is the final part of the frame structure. It typically contains two important components:

Frame Check Sequence (FCS): The FCS is a field in the trailer that is used for error detection. It is a checksum or a cyclic redundancy check (CRC) value calculated based on the contents of the entire frame, including the header, data, and sometimes the trailer itself.

End Delimiter: The end delimiter is a specific bit pattern or sequence of bits that marks the end of the frame. It helps the receiving device recognize the end of the frame and differentiate it from subsequent frames.

Thus, the trailer, along with the header and data, forms a complete data-link frame. It is used for reliable transmission of data across a network by incorporating error detection mechanisms and frame boundaries.

"CodeHS Gymnastic Mats"
I cant get it to calculate the area of the Mat or the Room. Any help?

Here is my code:

function start(){

var widthMat= readInt("What is the width of the mat in feet?");

var lengthMat= readInt("What is the length of the mat in feet?");

function calculateArea(width,length){

var area = width*length;

return area;

}

var widthRoom = readInt("What is the width of the room in feet?");

var lengthRoom = readInt("What is the length of the room in feet?");

println("You will need 10 mats to cover the room");

}

function calculateArea(width,length){

var area = width*length;

return area;

}

Answers

It looks like your calculateArea() function is defined within the start() function. This means that it cannot be accessed outside of the start() function, including in the println() statement at the end. You can fix this by moving the calculateArea() function outside of the start() function so that it can be called from anywhere in your code.

Here's an updated version of your code that should work:

function start() {

 var widthMat = readInt("What is the width of the mat in feet?");

 var lengthMat = readInt("What is the length of the mat in feet?");

 

 var areaMat = calculateArea(widthMat, lengthMat);

 println("The area of the mat is " + areaMat + " square feet.");

 

 var widthRoom = readInt("What is the width of the room in feet?");

 var lengthRoom = readInt("What is the length of the room in feet?");

 

 var areaRoom = calculateArea(widthRoom, lengthRoom);

 println("The area of the room is " + areaRoom + " square feet.");

 

 var matsNeeded = Math.ceil(areaRoom / areaMat);

 println("You will need " + matsNeeded + " mats to cover the room.");

}

function calculateArea(width, length) {

 var area = width * length;

 return area;

}

In this version of the code, the calculateArea() function is defined outside of the start() function, so it can be accessed from anywhere in the code. The start() function now calls calculateArea() twice, once for the mat and once for the room, and saves the results to variables. It then calculates the number of mats needed to cover the room and prints out all the results using println().

Note that I also added a line to round up the number of mats needed using Math.ceil(), since you can't buy a fraction of a mat.

Which of the followings is NOT true? A. Larger sample size can reduce the probability of inference error caused by sampling. B. Spending money to increase your sample size from 100 to 1000 has the same impact on reducing sampling error as spending the same amount of money to increase your. sample from 1100 to 2000. C. Testing the entire population if often not feasible. D. Researchers infer population level responses by testing with a subset of population. E. Determining sample size is an important issue when designing a survey/an experiment

Answers

The statement that is NOT true is B. Spending money to increase your sample size from 100 to 1000 has the same impact on reducing sampling error as spending the same amount of money to increase your sample from 1100 to 2000.

A larger sample size generally reduces the probability of inference error caused by sampling (A). However, the impact of increasing the sample size is not linear. In option B, it suggests that spending the same amount of money to increase the sample size from 100 to 1000 has the same impact as increasing it from 1100 to 2000. This statement is incorrect because the diminishing returns of sample size make it less effective to reduce sampling error as the sample size increases.

Options C and D are true. Testing the entire population is often not feasible (C), so researchers rely on testing a subset of the population to infer population-level responses (D). This is a practical and cost-effective approach.

Option E is also true. Determining the appropriate sample size is crucial when designing a survey or experiment. It ensures that the sample is representative of the population and provides sufficient statistical power to make meaningful inferences. A sample size that is too small may lead to unreliable results, while an excessively large sample may be unnecessary and inefficient.

Answers

The pairs that are likely to have a positive cross-price elasticity are a) smartphones and chargers, b) MP3 players and earphones, and c) regular bikes and electric bikes.

Cross-price elasticity measures the responsiveness of demand for one good to changes in the price of another good. A positive cross-price elasticity indicates that the two goods are substitutes, meaning that an increase in the price of one good lead to an increase in the demand for the other good.

a) Smartphones and chargers: These goods are complementary, as smartphones require chargers for operation. When the price of smartphones increases, the demand for chargers is also likely to increase, leading to a positive cross-price elasticity.

b) MP3 players and earphones: MP3 players and earphones are typically used together, and an increase in the price of MP3 players may lead to an increase in the demand for earphones. Thus, there is a positive cross-price elasticity between these two goods.

c) Regular bikes and electric bikes: Regular bikes and electric bikes serve a similar purpose, and consumers may choose between these two.

In the most basic level, internet supports point to point asynchronous communication is false. In the most basic level, the internet supports point-to-point synchronous communication. So the statement is False.

Point-to-point communication refers to the direct transmission of data between two endpoints, such as a client and a server. Synchronous communication means that the sender and receiver are in sync and exchange data in real-time.

This is commonly seen in protocols like TCP (Transmission Control Protocol), where data is sent and acknowledged in a synchronized manner. Asynchronous communication, on the other hand, allows for non-real-time, independent data transmission and processing between endpoints.

distributed training of deep neural networks: theoretical and practical limits of parallel scalability

Answers

Distributed training of deep neural networks is an efficient way of parallel computing in neural networks, it uses distributed computational resources to train the neural network models.



The practical factors that limit the parallel scalability of distributed training of deep neural networks include the computational power, the network topology, and the data distribution. The computational power of each node determines the size of the model that can be trained in the distributed setting. If the computational power of each node is low, then the size of the model that can be trained is small, which limits the scalability of the distributed training process.

The network topology is another practical factor that affects the scalability of the distributed training process. If the network topology is not optimized for the distributed training process, then there will be bottlenecks in the communication between different computing nodes, which limits the performance of the distributed training process.

The data distribution is also an important practical factor that affects the scalability of the distributed training process. If the data is not evenly distributed among different computing nodes, then some nodes will be underutilized while others will be overutilized. This leads to a waste of computational resources and limits the scalability of the distributed training process.

In conclusion, the distributed training of deep neural networks is an efficient way of parallel computing in neural networks. However, the parallel scalability of the distributed training process is limited by both theoretical and practical factors. The theoretical factors include the communication overhead and the granularity of the parallelism, while the practical factors include the computational power, the network topology, and the data distribution. These factors should be carefully considered when designing and implementing distributed training algorithms for deep neural networks.

Answers

In a physical star topology, if a workstation loses its physical connection to another device, the device is disconnected from the network.

A physical star topology is a type of network topology in which devices are connected to a central hub or switch. Each device has its own separate cable that connects it to the hub or switch.The hub or switch serves as the central connection point for all devices on the network. This topology is widely used in local area networks (LANs) because it is simple to implement and maintain.If a workstation loses its physical connection to another device, it cannot communicate with other devices on the network.

The device will be isolated and cannot send or receive data from other devices. As a result, the network's performance may be negatively impacted. The network will continue to function, but the device will no longer be able to participate in the network. In summary, if a workstation loses its physical connection to another device in a physical star topology, the device is disconnected from the network, and it will no longer be able to communicate with other devices on the network.
