Answer:

code = 010100000001101000101

Explanation:

These are the steps:

The inequality is written as follows:

2^k - 1 >= M + K

where M = 16.

Therefore, the next step will be, arranging the data bits and checking the bits.

This is done as follows:

Bit position              Number             Check bits             Data Bits

21                                   10101

20                                  10100

The bits are thus checked in this manner, up to bit position 1

Therefore, the code is written as:

010100000001101000101

Answer:

code = 010100000001101000101

Explanation:

Steps:

The inequality yields 2^{k} - 1 > = M+K, where M = 16. Therefore,

The second step will be to arrange the data bits and check the bits. This will be as follows:

Bit position              number              Check bits            Data Bits

21                                   10101

20                                  10100

The bits are checked up to bit position 1

Thus, the code is 010100000001101000101

Write a statement to add the key Tesla with value USA to car_makers. Modify the car maker of Fiat to Italy. Sample output for th
marishachu [46]

Answer:

Input code:

car_makers = {'Honda': 'Japan', 'Fiat': 'Germany'}

#add Tesla and USA as corresponding value

car_makers['Tesla'] = 'USA'

#change Fiat entry to Italy instead of Germany

car_makers['Fiat'] = 'Italy'

print(car_makers)

print('Honda made in', car_makers['Honda'])

print('Fiat made in', car_makers['Fiat'])

print('Tesla made in', car_makers['Tesla'])

Explanation:

The first line is a define object in the python code, containing two entries of Honda and Fiat and their respective countries.

The python code adds an entry to the object "car maker" using the bracket notation, the tesla car from USA.

The country of the Fiat car is changed from Germany to Italy, using the bracket notation.

The output of the complete object and the individual cars is given.

<u>output of the python code:</u>

{'Honda': 'Japan', 'Fiat': 'Italy', 'Tesla': 'USA'}

Honda made in Japan

Fiat made in Italy

Tesla made in USA.

You are an ISP. For the Address Block 195.200.0.0/16 a. If you have 320 Customers that need 128 addresses/customer - will there
12345 [234]

Answer:

a. The network will not satisfy the customers because the required addresses is 128 but what can be offered is 126.

b. 195.200.0.0/22

Explanation:

195.200.0.0/16

The number of bits to give 512 is 9

2^9=512

2^8=256 which is not up to our expected 320 customers that requires a network ip

Note we have to use a bit number that is equal or higher than our required number of networks.

The number of host per each subnet of the network (195.200.0.0/25) is (2^7)-2= 128-2=126

The network will not satisfy the customers because the required addresses is 128 but what can be offered is 126.

b. 64 customers requires  6 bits to be taken from the host bit to the network bit

i.e 2^6 = 64

195.200.0.0/22

The number of host per each subnet of the network (195.200.0.0/22) is (2^10)-2=1024 - 2 = 1022 hosts per subnet

This network meet the requirement " 64 customers want 128 addresses/customer "

adelina 88 [10]

public static void main(String[] args)

{

int n=4;

// print the upper half

for(int a=1;a<=n;a++)

{

for(int b=1;b<=n-a;b++)

{

// print the spaces

System.out.print(" ");

}

// print the * of upper half

for(int x=1;x<=a*2-1;x++)

{

// print the *

System.out.print("*");

}

// print newline

System.out.println();

}

// print the lower half

for(int y=n-1;y>0;y--)

{

for(int z=1;z<=n-y;z++)

{

// print the spaces

System.out.print(" ");

}

for(int m=1;m<=y*2-1;m++)

{

// print the *

System.out.print("*");

}

// print newline

System.out.println();

}

}

}

Explanation:

Declare a variable "n" and initialize it with 4. First print the spaces (" ") of the upper half with the help of nested for loop.Then print the "*" of the upper half with for loop. Similarly print the lower half in revers order. This will print the required shape.

Output:

  *
