Answer:

Attached is the solution. Hope it helps:

a) The class of context-free languages is not closed under intersection, as shown by the example of[tex]A = [ a^m b^n c^n | m, n \geq 0 ][/tex] and [tex]B = [a^n b^n c^m | m, n \geq 0 ][/tex]

Given that;

We have seen in class that the sets of both regular and context-free languages are closed under the union, concatenation, and star operations.

(a) We're given two languages A and B:

[tex]A = [ a^m b^n c^n | m, n \geq 0 ][/tex]

[tex]B = [a^n b^n c^m | m, n \geq 0 ][/tex]

We want to show that the intersection of A and B is not context-free.

To do this, we can use the fact that the language [tex]C = [a^n b^n c^n | n \geq 0 ][/tex] is not context-free.

Assume for contradiction that the intersection of A and B, which we'll call D, is context-free.

Since context-free languages are closed under intersection, we'd have D = A ∩ B is also a context-free language.

Now, notice that D is a subset of C (if a string belongs to D, it must belong to C as well).

However, C is not context-free, as given.

This contradicts our assumption that D is context-free.

Therefore, we can conclude that the class of context-free languages is not closed under intersection, as shown by the example of[tex]A = [ a^m b^n c^n | m, n \geq 0 ][/tex] and [tex]B = [a^n b^n c^m | m, n \geq 0 ][/tex]

(b) Using the result from part (a), we can now show that the set of context-free languages is not closed under complementation.

Let's consider the complement of a context-free language.

If the complement of a context-free language were always context-free, we could take the complement of C and obtain a context-free language.

However, as established earlier, C is not context-free.

Hence, we can conclude that the set of context-free languages is not closed under complementation.

#SPJ3

Answer:

The bandwidth is 3200 Kbps

Explanation:

Given:

The length of the point to point link = 50 km = 50×10³ = 50000 m

Speed of transmission = 2 × 10⁸ m/s

Therefore the propagation delay is the ratio of the length of the link to speed of transmission

Therefore,  [tex]t_{prop} = \frac{distance}{speed}[/tex]

[tex]t_{prop} = \frac{50000}{2*10^{8} }=2.5*10^{-4}[/tex]

Therefore the propagation delay in 25 ms

100 byte = (100 × 8) bits

Transmission delay = [tex]\frac{(100*8)bits }{(x)bits/sec}[/tex]

If propagation delay is equal to transmission delay;

[tex]\frac{(100*8)bits }{(x)bits/sec}= \frac{50000}{2*10^{8} }[/tex]

[tex]x=\frac{100*8*2*10^{8} }{50000}[/tex]

[tex]x=\frac{100*8}{2.5*10 ^-4}=3200000[/tex]

x = 3200 Kbps

Answer:

The complete question is here:

Consider a point-to-point link 2 km in length. At what bandwidth would propagation delay (at a speed of 2 x 108 m/s) equal transmission delay for

(a) 100-byte packets?

(b) 512-byte packets?

Explanation:

Given:

Length of the link = 50 km

Propagation delay = distance/speed = d/s

To find:

At what speed would propagation delay (at a speed 2 x 10^8 meters/second) equal transmit delay for 100 byte packets?

Solution:

Propagation Delay = t prop

                                 = 50 * 10^3 / 2 * 10^8

                                 = 50000 / 200000000

                                 = 0.00025

                                 = 25 ms

(a) When propagation delay is equal to transmission delay for 100 packets:

Transmission Delay = packet length / data rate = L / R

So when,

Transmission Delay = Propagation Delay

100 * 8  / bits/sec = 50 * 10^3  / 2 * 10^8

Let y denotes the data rate in bit / sec

speed = bandwidth = y bits/sec

         100 * 8  / y bits/sec = 50 * 10^3  / 2 * 10^8

                        y bit/sec   =  100 * 8  / 25 * 10^ -5

                                         = 800 / 0.00025

                                     y  = 3200000 bit/sec

                                      y = 3200 Kbps

(b) 512-byte packets

512 * 8  / y bits/sec = 50 * 10^3  / 2 * 10^8

                        y bit/sec   =  512 * 8  / 25 * 10^ -5

                                         = 4096 / 0.00025

                                     y  = 16384000 bit/sec

                                      y = 16384 Kbps

Answer:

canadian_capitals = {"Alberta":"Edmonton", "British Columbia":"Victoria", "Manitoba":"Winnipeg"}

mexica_capitals ={"Aguascalientes":"Aguascalientes", "Baja California":"Mexicali", "Baja California Sur":"La Paz"}

us_capitals ={"Alabama":"Montgomery", "Alaska":"Juneau", "Arizona":"Phoenix"}

nafta_capitals = {}

nafta_capitals.update(canadian_capitals)

nafta_capitals.update(mexica_capitals)

nafta_capitals.update(us_capitals)

print(nafta_capitals)

Explanation:

The code is written in python.

canadian_capitals = {"Alberta":"Edmonton", "British Columbia":"Victoria", "Manitoba":"Winnipeg"}   I created the first dictionary with the variable name called canadian_capital.  Notice the province of Canada is mapped to to their respective capitals.

mexica_capitals ={"Aguascalientes":"Aguascalientes", "Baja California":"Mexicali", "Baja California Sur":"La Paz"}   I created the second dictionary with the variable name called mexican_capital. The states are also mapped to their respective capitals.

us_capitals ={"Alabama":"Montgomery", "Alaska":"Juneau", "Arizona":"Phoenix"}   I created the third dictionary with the variable name called us_capital.  The states are also mapped to their respective capitals.

nafta_capitals = {}  This is an empty dictionary with the variable name nafta_capitals to combine the 3 dictionaries.

nafta_capitals.update(canadian_capitals)  I updated the empty dictionary with the canadian_capitals dictionary.

nafta_capitals.update(mexica_capitals)  I also added the mexica_capitals dictionary to the nafta_capitals dictionary.

nafta_capitals.update(us_capitals)  I also added the us_capitals dictionary to the nafta_capitals dictionary.

print(nafta_capitals)   The whole 3  dictionaries have been combined to form the nafta_capitals dictionary. The print function displays the already combine dictionaries.

Answer:

The cpp program for conversion is given below.

#include <iostream>

using namespace std;

int main() {

// declaring and initializing constant variables with standard values

   const  double INCHES_IN_MILE=63360;

   const  double FEET_IN_MILE=5280;

   const  double YARDS_IN_MILE=1760;

   // declaring and initializing miles with a random value

   double miles=4.0;

// declaring and computing inches in miles

double inch = INCHES_IN_MILE*miles;

// declaring and computing feet in miles

double feet = FEET_IN_MILE*miles;

// declaring and computing yards in miles

double yard = YARDS_IN_MILE*miles;

// displaying all the calculated values

std::cout<<miles<<" miles is "<<inch<<" inches"<<std::endl;

std::cout<<miles<<" miles is "<<feet<<" feet"<<std::endl;

       std::cout<<miles<<" miles is "<<yard<<" yards"<<std::endl;

       return 0;      

}

OUTPUT

4 miles is 253440 inches

4 miles is 21120 feet

4 miles is 7040 yards

Explanation:

The steps in the program are as described.

1. All the three constant variables, mentioned in the question, are declared as double and initialized. These variables hold the fixed conversion values for inches, feet and yards in one mile.

2. The variables are declared constant using the keyword, const.

3. The variable to hold value for mile, miles, is declared as double and initialized with a random value.

4. Next, three more variables are declared as double. These variables will hold the calculated values for inches, feet and yards in the given value of mile.

5. The values are calculated for inches, feet and yards for the given value of variable, miles and stored in the variables mentioned in step 3.

6. These values are displayed to the console along with explanations.

7. The program ends with the return statement.

8. The value of variable, miles, is hard coded in the program and not taken from the user.

9. There is no interaction with the user in this program as this is not mentioned in the question.

10. The program works for all numeric value of the variable, miles, since double accepts integers also.

11. The program can be tested by changing the value of variable, miles.

Answer:

The solution code is written in Python:

Explanation:

Based on the information given in the question, we presume the cost per 500 miles is $1.10 per pound ($2.20 / 2 pound).

Create a variable COST_PER_500MI to hold the value of cost per 500 miles (Line 1). Next, prompt user input the weight and assign it to variable weight (Line 3). Calculate the shipping charge and display it using print function (Line 4-5).

Final answer:

A program to calculate shipping charges can be created by converting the weight of a package to ounces and using the provided rate structure. For a 2-pound package, the cost to ship would be $6.88, following the given rate system where the first 3 ounces cost $1.95 and each additional ounce costs $0.17. The per 500-mile charges are not prorated.

Explanation:

The given scenario requires the creation of a simple program that calculates shipping charges based on the weight of a package and the distance it needs to be shipped. According to the details, there's a flat rate for the first 3 ounces, and then an additional, per ounce charge after that. If a 2-pound package is shipped, we can calculate the cost based on the conversion of pounds to ounces, and then apply the pricing rules provided. Since there are 16 ounces in one pound, a 2-pound package would be equivalent to 32 ounces. The cost would then be computed as follows:

Total Cost = Base cost for first 3 ounces + (Number of additional ounces x Cost per additional ounce)

For a 32 ounce package, this would be:

Total Cost = $1.95 + (29 x $0.17) = $1.95 + $4.93 = $6.88

There is no need to prorate the charge per 500 miles as the example provided indicates a flat charge is applied per 500-mile increment. Handling user input correctly in a program is also essential to ensure the right calculations are made based on what the user enters for the package weight and distance.

def read_file(fileName = None):

  try:

      File = open(fileName,"r") # opening file in read mode

  list_words.extend(text.split(' '))

  return list_words

def determine_difference(a_list,b_list):

Answer:

Data encapsulation

Explanation:

When we send data to someone else across another network, this data travels down a stack of layers of the TCP/IP model. Each layer of the TCP/IP layer encapsulates data or hides the data by adding headers and sometimes trailers. This packaging is what is known as data encapsulation. The data starts at the application layer and trickles down beneath. As it moves down the layers, it is encoded or compressed to a standard format and sometimes encrypted for security purposes.

Answer:

void printAttitude (int pint){

if (pint == 1){

System.out.println("disagree");

}

if (pint == 2){

System.out.println("no opinion");

}

if (pint == 3){

System.out.println("agree");

}

}

Explanation:

Answer:

public class num4 {

   public static void main(String[] args) {

       int para =2;

       printAttitude(para);

   }

   static void printAttitude( int para){

       if(para==1){

           System.out.println("disagree");

       }

       else if (para == 2){

           System.out.println("no option");

       }

       else if (para==3){

           System.out.println("agree");

       }

   }

}

Explanation:

Using Java Programming language:

Three if and else if statements are created to handle the conditions as given in the question (1,2,3) The output of disagree, no option and agree respectively is displayed using Java's output method System.out.println When these conditions are true

No else statement is provided to handle situations when the parameter value is neither (1,2,3), as a result, then program will do nothing and simply exits.

Answer:

Here is the Python program:

import random  #to generate random numbers

low = 1  #lowest range of a guess

high = 100  #highest range of a guess

attempts=0   # no of attempts

def guess_number(low, high, attempts):  #function for guessing a number

   print("Guess a number between 1 and 100")      

#prompts user to enter an integer between 1 to 100 as a guess

   number = random.randint(low, high)  

#return randoms digits from low to high

   for _ in range(attempts):  #loop to make guesses

       guess = input("Enter a number: ")   #prompts user to enter a guess

       num = int(guess)  #reads the input guess

       if num == number:  # if num is equal to the guess number

           print('Congratulations! You guessed the right number!')    

           command= input("Do you want to play another game? ")

#asks user if he wants to play another game

           if command=='Y':  #if user enters Y  

               guess_number(low,high,attempts)  #starts game again

           elif command=='N':  #if user types N

               exit() #exits the program

       elif num < number:   #if user entered a no less than random no

           print('Too low, Try Higher')  # program prompts user to enter higher no

       elif num > number: #if user entered a no greater than random no

           print('Too high, Try Lower') # program prompts user to enter lower no

       else:  #if user enters anything else

           print("You must enter a valid integer.")  

#if user guessed wrong number till the given attempts

   print("You failed to guess the number correctly in {attempts} attempts.".format(attempts=attempts))  

   exit() # program exits

Explanation:

The program has a function guess_number which takes three parameters, high and low are the range set for the user to enter the number in this range and attempts is the number of tries given to the user to guess the number.

random.randint() generates integers in a given range, here the range is specified i.e from 1 to 100. So it generates random number from this range.

For loop keeps asking the user to make attempts in guessing a number and the number of tries the user is given is specified in the attempts variable.

If the number entered by the user is equal to the random number then this message is displayed: Congratulations! You guessed the right number! Then the user is asked if he wants to play one more time and if he types Y the game starts again but if he types N then the exit() function exits the game.

If the number entered as guess is higher than the random number then this message is displayed Too high, Try Lower and if the number entered as guess is lower than the random number then this message is displayed Too low, Try Higher.

If the user fails to guess the number in given attempts then the following message is displayed and program ends. You failed to guess the number correctly in {attempts} attempts.

You can call this function in main by passing value to this function to see the output on the screen.

guess_number(1, 100, 5)

The output is shown in screenshot attached.

The ARPANET network became functional in 1969, linking scientific and academic researchers across the United States.

Explanation:

ARPA Net is the network that has become functional in 1969 in united States. The basic purpose of this network is to link all the researchers and scientists across united states. The full form of ARPANet is Advanced Research Project Agency Network.

The importance of this network is increase because small chunks of data that are called packets has been proposed for data transmission in the network. The data is divided into small packets and send it over the network, at destination point these packets are combined together and become orignal information.

Explanation:

Flash and RAM are two types of memory used in microcontrollers like PIC, with differences such as Flash being non-volatile and RAM being volatile. Configuration words are usually stored in Flash memory, and special linear data memory can be used for larger structures. Even while accessing data RAM, the Bank Select Register should typically be set to the correct bank, but some common areas are accessible from all banks.

1. Flash and RAM are two types of memories used in microcontrollers like PIC, with significant differences. Flash Memory, being non-volatile, retains its information even when power is turned off, generally used for storing the program. On the other side, RAM (Random Access Memory) is volatile and loses its information when power is removed, typically used for temporary storage during program execution.

2+3. The specific number of RAM and Flash locations, as well as the bit size at each location, depends on the specific PIC microcontroller model. In general, one could read these details from the datasheet for the specific part.

4. Configuration words are usually associated with the Flash memory, as they are used to set up certain parameters for the chip that remain constant during operation.

5. Linear Data Memory is important for larger data structures such as arrays or buffers that require more than 80 bytes. Having this extra memory space allows more complex calculations and data manipulations.

6. Lastly, when accessing data RAM with direct addressing, the correct memory bank that includes our desired memory location should be selected into the BSR (Bank Select Register). However, there are ‘common’ areas in data RAM accessible from all banks, typically which include Special Function Registers (SFRs) and some general purpose registers.

The answer & explanation for this question is given in the attachment below.

The SQL query selects vendor contacts' first names followed by last initials and phone numbers without area codes from the Vendors table. It filters vendors with the 559 area code and sorts results alphabetically by first name and last name.

Below is the SQL SELECT statement that fulfills your requirements:

```sql

SELECT

   CONCAT(SUBSTRING_INDEX(ContactName, ' ', 1), ' ', LEFT(SUBSTRING_INDEX(ContactName, ' ', -1), 1), '.') AS Contact,

   SUBSTRING(VendorPhone, 5) AS Phone

FROM

   Vendors

WHERE

   VendorPhone LIKE '559%'

ORDER BY

   SUBSTRING_INDEX(ContactName, ' ', 1),

   SUBSTRING_INDEX(ContactName, ' ', -1);

```

This query selects the ContactName column from the Vendors table, concatenates the first name and the first letter of the last name, followed by a period, to create the Contact column.

It then extracts the phone number without the area code from the VendorPhone column and stores it in the Phone column.

Finally, it filters the results to include only vendors with the 559 area code and sorts the result set by first name and last name.
