Provide an example of a physical network medium, describing some of the key characteristics of the medium that you have chosen as your example. Briefly explain how the Physical Layer (Layer 1 of the OSI Model) responsibilities are met by this medium.

Answers

Answer 1

Ethernet cable serves as a physical network medium that meets the responsibilities of the Physical Layer in the OSI Model by facilitating the reliable transmission of data signals between network devices. It provides a robust and cost-effective solution for establishing wired connections in LAN environments.

One example of a physical network medium is Ethernet cable. Ethernet cable is a widely used medium for connecting devices in a local area network (LAN). It consists of copper wires encased in a protective insulation, and it comes in different categories such as Cat5, Cat6, and Cat7, each with varying capabilities and speeds. Ethernet cable provides a reliable and cost-effective solution for transmitting data signals over short to medium distances.

Ethernet cable meets the responsibilities of the Physical Layer in the OSI Model by providing a physical connection between network devices. It ensures the transmission of bits from one device to another by carrying electrical signals through the copper wires. The Physical Layer responsibilities include encoding and decoding data into electrical signals, managing the physical connection, and handling issues such as signal attenuation, interference, and noise.

Ethernet cable achieves these responsibilities through various mechanisms. It uses specific encoding schemes, such as Manchester encoding or 4B5B encoding, to convert data bits into electrical signals that can be transmitted over the cable. It also employs techniques like twisted-pair wiring and shielding to minimize signal degradation and protect against electromagnetic interference. Ethernet cable's physical connectors, such as RJ-45 connectors, provide a standardized interface for connecting devices.

In summary, Ethernet cable serves as a physical network medium that meets the responsibilities of the Physical Layer in the OSI Model by facilitating the reliable transmission of data signals between network devices. It provides a robust and cost-effective solution for establishing wired connections in LAN environments.

Create a program that asks users to enter sales for 7 days. The
program should calculate and display the following data:
• The average sales
• The highest amount of sales.
this is java programming

Answers

The program prompts the user to enter sales figures for 7 days. It then calculates and displays the average sales and the highest sales amount.

The program will prompt the user to enter the sales for each of the 7 days. It will store these sales values in an array or a collection. After receiving all the input, the program will calculate the average sales by summing up all the sales values and dividing the sum by 7 (the number of days). This will give the average sales per day.

Next, the program will find the highest sales amount by iterating through the sales values and keeping track of the highest value encountered. Finally, the program will display the calculated average sales and the highest sales amount to the user.

By performing these calculations, the program provides useful information about the sales performance, allowing users to analyze and evaluate the data effectively.

This program script file processes the Student ID and the Student Social Security Number (SSN). Requires you to first get the number of students (Used the size of a 2-Dimensional list) that will store the Student ID and the Student Social Security Number (SSN). You are required to display the contents of the list(s) and then write the contents to a students_file.txt
The Python program requirements:
The Python script requires the following functions:
Function 1: call a value returning function for inputting the number of students. Within that function, use an exception handler to validate that an integer is being input and that the integer must have a value > 0.
Function 2: call a value returning function for inputting the student ID which is a 7-digit integer and returning it. Use an exception handler to validate that the student ID does not exceed 7 digits. You can use the str() function to turn an integer into a string and then use the len() function to check the length of the string. If you aren’t able to figure that out, then try checking to see if the student ID is larger than the largest 7-digit Integer that you can think of.
Function 3: call a value returning function for inputting the student social security numbers (like 111-22-3333, 222-33-4444) that are strings and return them.
Function 4: call a void function that will display the contents of the list(s) after all input is complete
Function 5: call a void function that will write the contents of the list(s) to a txt file (students_file.txt).
Functions and Exception Handlers are required/use in this program as described below:

b. Is this problem in NP? (Yes or No or Not proved yet)
c. Explain the reason of (b).
d. Is this problem reducible from/to an NP-complete problem? (Yes or No)

f. Is this problem in NP-complete or NP-hard? (NP-complete or NP-hard)
g. Explain the reason of (f).
h. Write your design of a polynomial-time algorithm for this problem.
i. Analyze the algorithm in (h).

Answers

a. No, the N-Queens problem is not in the P-class. The P-class includes decision problems that can be solved by a deterministic Turing machine in polynomial time. However, solving the N-Queens problem requires an exhaustive search of all possible configurations, which has an exponential time complexity.

b. Yes, the N-Queens problem is in NP (Nondeterministic Polynomial time). NP includes decision problems that can be verified in polynomial time. In the case of the N-Queens problem, given a solution (a placement of queens on the board), it can be verified in polynomial time whether the queens are placed in such a way that they do not attack each other.

c. The reason the N-Queens problem is in NP is that given a solution, we can verify its correctness efficiently. We can check if no two queens attack each other by examining the rows, columns, and diagonals.

d. No, the N-Queens problem is not reducible from/to an NP-complete problem. NP-complete problems are those to which any problem in NP can be reduced in polynomial time. The N-Queens problem is not a decision problem and does not have a direct reduction to/from an NP-complete problem.

e. N/A

f. The N-Queens problem is NP-hard. NP-hard problems are at least as hard as the hardest problems in NP. While the N-Queens problem is not known to be NP-complete, it is considered NP-hard because it is at least as difficult as NP-complete problems.

g. The reason the N-Queens problem is considered NP-hard is that it requires an exhaustive search over all possible configurations, which has an exponential time complexity. This makes it at least as hard as other NP-complete problems.

h. Design of a polynomial-time algorithm for the N-Queens problem:

Start with an empty NxN chessboard.

Place the first queen in the first row and first column.

For each subsequent row:

For each column in the current row:

Check if the current position is under attack by any of the previously placed queens.

If not under attack, place the queen in the current position.

Recursively move to the next row and repeat the process.

If all positions in the current row are under attack, backtrack to the previous row and try the next column.

Repeat this process until all N queens are placed or all configurations are exhausted.

If a valid solution is found, return it. Otherwise, indicate that no solution exists.

i. The above algorithm has a time complexity of O(N!) in the worst case, as it explores all possible configurations. However, for smaller values of N, it can find a solution in a reasonable amount of time. The space complexity is O(N) for storing the positions of the queens on the board.

Using the same idea from the previous problem, create a program that sorts an array from smallest to largest for any user without using any Built-In MATLAB functions (loops can be used). Prompt the user to input an array of any size. Tell the user to enter -1 when they are done inputting their array. Once they are done, display their new sorted array. Remember, do not ask the user for the size of the array, only to input -1 to indicate they are done.

Answers

Here's a possible solution in MATLAB:

matlab

% Prompt the user to input an array of any size.

disp('Enter elements of the array (or enter -1 to stop):');

% Initialize an empty array and a count variable.

arr = [];

count = 0;

% Use a while loop to keep reading input until the user enters -1.

while true

   % Read the next input value.

   val = input('> ');

   

   % If the user entered -1, break out of the loop.

   if val == -1

       break;

   end

   

   % Add the value to the array and increment the count.

   arr(end+1) = val;

   count = count + 1;

end

% Sort the array using a bubble sort algorithm.

for i = 1:count-1

   for j = 1:count-i

           arr(j+1) = temp;

end

% Display the sorted array.

disp(arr);

This program reads input values from the user until they enter -1, at which point it sorts the array using a simple bubble sort algorithm. Finally, it displays the sorted array to the user.

It looks like the code provided has some syntax errors and logical errors. Here's a corrected version of the code:

#include <iostream>

using namespace std;

int main() {

   int sum = 0;

   int mylist[] = {8, 12, 3, 4, 12, 9, 8};

   int size = sizeof(mylist)/sizeof(mylist[0]);

   // Print the elements of the array

   for (int i = 0; i < size; i++) {

   cout << "Sum using for loop: " << sum << endl;

   // Reset the sum variable

   sum = 0;

   // Sum the elements of the array using a do-while loop

   int i = size - 1;

   do {

       sum += mylist[i];

       i--;

   } while (i >= 0);

   cout << "Sum using do-while loop: " << sum << endl;

   return 0;

}

This code first initializes an array mylist with the given values, and then prints out all the elements of the array.

After that, there are two loops that calculate the sum of the elements in the array. The first loop uses a simple for loop to iterate over each element in the array and add it to the running total in the sum variable. The second loop uses a do-while loop to iterate over the same elements, but starting from the end of the array instead of the beginning.

FD1: X1, X2, X3 X5, X6 FD2: X2 → X4, X8 FD3: X4 → X7

Answers

After normalization, R1 (X1, X2, X3, X5, X6) and R2 (X2, X4, X7, X8) are in 3NF, ensuring no partial dependencies and each non-key attribute being fully dependent on the candidate key.

To determine the normal form of relation R and normalize it, let's follow these steps:

i. What Normal form is R in right now? Why is this the case?

Based on the given functional dependencies, we can analyze the normal form of relation R.

- FD1: X1, X2, X3 → X5, X6 (Partial dependency)

- FD2: X2 → X4, X8 (Partial dependency)

- FD3: X4 → X7 (Partial dependency)

Since there are partial dependencies in the functional dependencies of relation R, it is currently in 2NF (Second Normal Form).

ii. What actions would you take to normalize R to the next higher normal form? (Describe the steps)

To normalize R to the next higher normal form (3NF), we need to perform the following steps:

1. Identify the candidate keys of R.

2. Determine the functional dependencies that violate the 3NF.

3. Decompose R into smaller relations to eliminate the violations and preserve the functional dependencies.

iii. Follow the steps you described in the prior question to normalize R to the next higher form. Be sure to show all of the steps.

1. Identify the candidate keys of R:

  The candidate keys of R are {X1, X2, X3}.

2. Determine the functional dependencies that violate the 3NF:

  - FD1 violates 3NF as X1, X2, X3 determines X5 and X6, and X5 and X6 are not part of any candidate key.

  - FD2 does not violate 3NF as X2 is a part of the candidate key.

3. Decompose R into smaller relations to eliminate the violations and preserve the functional dependencies:

  We will create two new relations: R1 and R2.

  R1 (X1, X2, X3, X5, X6)   - Decomposed from FD1

  R2 (X2, X4, X7, X8)       - Remains the same

iv. Once you have normalized R, what normal forms are each of the two new relations in? Why?

- R1 (X1, X2, X3, X5, X6) is in 3NF (Third Normal Form) because it contains no partial dependencies and each non-key attribute is fully dependent on the candidate key.

- R2 (X2, X4, X7, X8) is already in 3NF because it does not have any violations of 3NF.

v. If any of the remaining relations are not in 3NF, normalize them to 3NF. Be sure to show all of your work.

Since both R1 and R2 are already in 3NF, no further normalization is required.

In summary, after normalization, R1 (X1, X2, X3, X5, X6) and R2 (X2, X4, X7, X8) are in 3NF, ensuring no partial dependencies and each non-key attribute being fully dependent on the candidate key.

Answers

The correct statement is: a. char charArray[2][2] = {{'a', 'b'}, {'c', 'd'}};

Option a (char charArray[2][2] = {{'a', 'b'}, {'c', 'd'}}) is correct because it declares a 2D array of characters with a fixed size of 2 rows and 2 columns. The array is initialized with specific character values in a nested initializer list.

Option b (char charArray[][] = {{'a', 'b'}, {'c', 'd'}}) is incorrect because it doesn't specify the size of the second dimension of the array, which is necessary for static array initialization.

Option c (char charArray[][] = {'a', 'b'}) is incorrect because it also doesn't specify the size of either dimension, which is required for static array declaration.

Option d (char charArray[2][] = {{'a', 'b'}, {'c', 'd'}}) is incorrect because it leaves the size of the second dimension unspecified, which is not allowed in C/C++.

You have a simple singly linked list of strings, this list has the strings stored in increasing alphabetic order. Your program needs to search for a string in the list. Considering that you are using a linear search, the order complexity of this search is: O O(nlogn) O(n) O O(logn) O(1)

Answers

the correct order complexity for the linear search in a singly linked list is O(n).

The order complexity of a linear search in a singly linked list is O(n).

In a linear search, each element of the linked list is checked sequentially until a match is found or the end of the list is reached. Therefore, the time complexity of a linear search grows linearly with the size of the list.

As the list size increases, the number of comparisons required to find a particular string increases proportionally. Hence, the time complexity of a linear search in a singly linked list is O(n), where n represents the number of elements in the list.

The other options mentioned:

- O(nlogn): This time complexity is commonly associated with sorting algorithms such as Merge Sort or Quick Sort, but it is not applicable to a linear search.

- O(logn): This time complexity is commonly associated with search algorithms like Binary Search, which requires a sorted list. However, in the given scenario, the list is not sorted, so this time complexity is not applicable.

- O(1): This time complexity represents constant time, where the execution time does not depend on the input size. In a linear search, the number of comparisons and the execution time grow with the size of the list, so O(1) is not the correct complexity for a linear search.

Therefore, the correct order complexity for the linear search in a singly linked list is O(n).

2. Suppose the numbers 0, 1, 2, ..., 9 were pushed onto a stack in that order, but that pops occurred at random points between the various pushes. The following is a valid sequence in which the values in the stack could have been popped: 3, 2, 6, 5, 7, 4, 1, 0, 9,8 Explain why it is not possible that 3, 2, 6, 4, 7, 5, 1, 0,9, 8 is a valid sequence in which the values could have been popped off the stack.

Answers

Let's consider the sequence 3, 2, 6, 4, 7, 5, 1, 0, 9, 8. We can see that the push operation for 4 occurs between the push operations for 6 and 7, which violates the rule mentioned earlier. Therefore, this sequence is not a valid popping sequence for the given stack.

To determine whether a sequence is a valid popping sequence for a given stack, we can use the following rule: For any two numbers x and y in the sequence, if x appears before y, then the push operation for x must have occurred before the push operation for y.

In the given sequence 3, 2, 6, 5, 7, 4, 1, 0, 9, 8, we can see that:

The push operation for 3 occurred first.

The push operation for 2 occurred after the push operation for 3 but before the push operation for 6.

The push operation for 6 occurred after the push operations for both 3 and 2.

The push operation for 5 occurred after the push operation for 6 but before the push operation for 7.

The push operation for 7 occurred after the push operations for both 6 and 5, but before the push operation for 4.

The push operation for 4 occurred after the push operation for 7.

The push operation for 1 occurred after the push operation for 4 but before the push operation for 0.

The push operation for 0 occurred after the push operations for both 1 and 4 but before the push operation for 9.

The push operation for 9 occurred after the push operation for 0 but before the push operation for 8.

Please respond to the following two questions: * What are *args and **kwargs used for? * What are List Comprehensions? Can you give an example of when to use it?

Answers

*args and **kwargs are used in Python to pass a variable number of arguments to a function. *args is used to pass a variable number of non-keyword arguments, while **kwargs is used to pass a variable number of keyword arguments. They allow flexibility in function definitions by handling different numbers of arguments without explicitly defining them.

List comprehensions are a concise way to create lists in Python by combining loops and conditional statements in a single line. They provide a compact and readable syntax. An example use case is when filtering a list and applying a transformation to the elements, such as creating a new list of squares of even numbers:

```python
even_numbers = [x**2 for x in original_list if x % 2 == 0]
```

Here, the list comprehension filters out the even numbers from `original_list` and squares each of them, resulting in `even_numbers`.

Question 5 Not yet answered Marked out of 2.00 P Flag question What is the output of the following code that is part of a complete C++ Program? Fact = 1; Num = 1; While (Num < 4) ( Fact Fact Num; = Num = Num+1; A Cout<

Answers

The provided code contains syntax errors, so it would not compile. However, if we assume that the code is corrected as follows:

int Fact = 1;

int Num = 1;

while (Num < 4) {

   Fact *= Num;

   Num = Num + 1;

}

std::cout << Fact;

Then the output of this program would be 6, which is the factorial of 3.

The code initializes two integer variables Fact and Num to 1. It then enters a while loop that continues as long as Num is less than 4. In each iteration of the loop, the value of Fact is updated by multiplying it with the current value of Num using the *= operator shorthand for multiplication assignment. The value of Num is also incremented by one in each iteration. Once Num becomes equal to 4, the loop terminates and the final value of Fact (which would be the factorial of the initial value of Num) is printed to the console using std::cout.

The lifetime of a new 6S hard-drive follows a Uniform
distribution over the range of [1.5, 3.0 years]. A 6S hard-drive
has been used for 2 years and is still working. What is the
probability that it i

Answers

The given hard-drive has been used for 2 years and is still working. We are to find the probability that it is still working after 2 years. Let A denote the event that the hard-drive lasts beyond 2 years. Then we can write the probability of A as follows:P(A) = P(the lifetime of the hard-drive exceeds 2 years).By definition of Uniform distribution, the probability density function of the lifetime of the hard-drive is given by:

f(x) = 1/(b - a) if a ≤ x ≤ b; 0 otherwise.where a = 1.5 years and b = 3.0 years are the minimum and maximum possible lifetimes of the hard-drive, respectively. Since the probability density function is uniform, the probability of the hard-lifetime of a new 6S hard-drive follows a Uniform distribution over the range of [1.5, 3.0 years]. We are to find the probability that a 6S hard-drive, which has been used for 2 years and is still working, will continue to work beyond 2 years.Let X denote the lifetime of the hard-drive in years.

Then X follows the Uniform distribution with a = 1.5 and b = 3.0. Thus, the probability density function of X is given by:f(x) = 1/(b - a) if a ≤ x ≤ b; 0 otherwise.Substituting the given values, we get:f(x) = 1/(3.0 - 1.5) = 1/1.5 if 1.5 ≤ x ≤ 3.0; 0 the integral is taken over the interval [2, 3] (since we want to find the probability that the hard-drive lasts beyond 2 years). Hence,P(A) = ∫f(x) dx = ∫1/1.5 dx = x/1.5 between the limits x = 2 and x = 3= [3/1.5] - [2/1.5] = 2/3Thus, the probability that a 6S hard-drive, which has been used for 2 years and is still working, will continue to work beyond 2 years is 2/3.

Answers

The output after executing the given pseudo code snippet is `d. FV`.

Here, the given function is a recursive function to encode a string with the given integer parameter. It will return the corresponding character of the integer passed as the parameter. This function will take a number as input and return a string. Each integer represents a letter. The code uses a base 26 encoding, meaning there are 26 possibilities for each digit. Each recursion of this function converts the digit to a letter. We will start by converting the base-10 integer to a base-26 number. The base-26 number is then converted to the corresponding character. In the given code snippet: If the given input integer `i` is less than `0`, then an exception will be thrown with the message `"Not Supported."`.Else if the given input integer `i` is greater than or equal to the length of the code, the given function will call itself recursively with `i` divided by the length of the `code` and added to the modulus of `i` with the length of the `code`. Otherwise, it will return the corresponding character for the given input integer by looking up in the `code` string. Since the given input integer is `5`, then the corresponding character is the `6th` character of the `code` string, which is `F`.So, the output after executing the given pseudo code snippet is `d.

a) Elaborate and explain try-except statements. Why would you use this in a program? [4 marks]
b) Elaborate and explain Multi-Way if statements. Use flowcharts and examples.

Answers

a) Try-except statements, also known as try-catch blocks, are used in programming to handle and manage exceptions or errors that may occur during the execution of a program. The syntax of a try-except statement consists of a try block, followed by one or more except blocks.

When a piece of code is placed inside a try block, it is monitored for any exceptions that may occur. If an exception is raised within the try block, the program flow is immediately transferred to the corresponding except block that handles that specific type of exception. The except block contains code to handle the exception, such as displaying an error message or taking appropriate corrective action.

Try-except statements are used in programs to provide error handling and make the program more robust. By anticipating and handling exceptions, we can prevent the program from crashing and provide graceful error recovery. This helps improve the reliability and stability of the program.

b) Multi-way if statements, also known as if-elif-else statements, allow us to execute different blocks of code based on multiple conditions. They provide a way to implement branching logic where the program can make decisions and choose different paths based on various conditions.

Inside the loop, write an if statement that checks to see if the user number is less than half the count of the loop or greater than 3.5 times the count of the loop, and if so, prints "In range".
For example, if the user enters 80, then "In range" prints 23 times.

Answers

Scanner is a class in Java used to get input of different data types from the user. It is a standard package used in Java programming. In this question, we are going to use Scanner to get a double from the user.

The program will ask the user for a double. Then the program will count from 0 to 100. Inside the loop, an if statement will check if the user number is less than half the count of the loop or greater than 3.5 times the count of the loop. If the condition is true, it will print "In range". The program in Java will look like this:

import java.util.Scanner;

public class Main{public static void main(String[] args) {

Scanner input = new Scanner(System.in);

System.out.print("Enter a double: ");

double userInput = input.nextDouble();

int count = 0;while(count <= 100) {

if(userInput < (count / 2) || userInput > (count * 3.5)) {

System.out.println("In range");}

count++;}}

The program is implemented to take a double value from the user using a Scanner and then loops over a range from 0 to 100 and prints out "In range" when the user's input is less than half the count of the loop or greater than 3.5 times the count of the loop.

Given an ellipse with rx = 2 and ry = 4, and center (4, 5),
Apply the mid-point ellipse drawing algorithm to draw the
ellipse.

Answers

The mid-point ellipse drawing algorithm is applied to draw an ellipse with rx = 2, ry = 4, and center (4, 5).

This algorithm calculates the coordinates of points on the ellipse based on its properties, allowing for accurate drawing without using curves.

To draw the ellipse using the mid-point ellipse drawing algorithm, we start by initializing the parameters: rx (horizontal radius) = 2, ry (vertical radius) = 4, and the center point = (4, 5).

Next, we use the algorithm to calculate the points on the ellipse. The algorithm involves dividing the ellipse into regions and using the midpoint property to determine the coordinates of the next points. We iterate through the regions and update the current point's coordinates based on the slope and the decision parameter.

The algorithm ensures that the resulting ellipse is symmetric and smooth. It calculates the points within the ellipse boundary accurately, creating a visually pleasing shape. By determining the coordinates iteratively, the algorithm avoids the need for complex mathematical calculations and curve plotting.

In conclusion, by applying the mid-point ellipse drawing algorithm to an ellipse with rx = 2, ry = 4, and center (4, 5), we can draw the ellipse accurately by calculating the coordinates of its points. The algorithm simplifies the process of drawing ellipses and ensures the resulting shape is smooth and symmetrical.

To prove the equation 1(2^(-1)) + 2(2^(-2)) + 3(2^(-3)) + ... + n(2^(-n)) = (2 - n + 2)(2^(-n)), we will use mathematical induction.

Base Case: For n = 1, we have 1(2^(-1)) = 1/2, and (2 - 1 + 2)(2^(-1)) = 3/2. The equation holds for n = 1.

Inductive Hypothesis: Assume the equation holds for some arbitrary positive integer k, i.e., 1(2^(-1)) + 2(2^(-2)) + ... + k(2^(-k)) = (2 - k + 2)(2^(-k)).

Inductive Step: We need to prove that the equation also holds for k+1.

Starting with the left-hand side (LHS):

LHS = 1(2^(-1)) + 2(2^(-2)) + ... + k(2^(-k)) + (k+1)(2^(-(k+1)))

= (2 - k + 2)(2^(-k)) + (k+1)(2^(-(k+1))) [Using the inductive hypothesis]

= (4 - k)(2^(-k)) + (k+1)(2^(-(k+1)))

= (4 - k) + (k+1)/2

= (4 - k) + (k+1)/2^1

= [(4 - k) + (k+1)/2^1]/(2^1)

= [(4 - k) + (k+1)(1/2)]/2

= [(4 - k) + (k+1)/2]/2

= [(4 - k + k+1)/2]/2

= (5/2)/2

= 5/4

≠ (2 - (k+1) + 2)(2^(-(k+1)))

The equation does not hold for k+1.

Therefore, the equation 1(2^(-1)) + 2(2^(-2)) + ... + n(2^(-n)) = (2 - n + 2)(2^(-n)) is not valid for all positive integers n.

The flow rate and SO 2 content of the gas mixture measured just before the packed tower are 25 m 3/min and 5.0 percent by volume, respectively. The working pressure is 1 atm and the temperature of the packed tower is 25C. Removal of 90 percent of the SO 2 is required, and water, initially pure with respect to SO 2, is to be used as the liquid solvent. The equilibrium line for SO 2 and water can be estimated by y=30x.

At present, 50,000 cars per week use the highway stretch after the toll is imposed it is projected that only 40,000 cars will use the highway stretch.a. Assuming that the marginal cost of highway use is constant and equal to 40 cents per car what is the net cost to society attributable to the increase in the toll.b. because of the reduced use of the highway the govt. would reduce the purchases of concrete from 20,000 per year to 19,000 per year. Thus if the price of concrete were $25 per ton the governments cost savings would be $25. However reduced need for concrete causes the price to fall to $24.50. Because of the reduction in price the purchase of concrete by non-government buyers increase by 300 tons per year. Assuming that the factor market for concrete is competitive, can the governments cost saving of $25,000 be appropriately used as the measure of social value of the cost savings that result from a government purchasing less concrete?
