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

be enough addresses to satisfy them? and explain why? b. Say the first block of 64 customers want 128 addresses/customer - what would the address space look like?

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 "

#Write a function called is_composite. is_composite should #take as input one integer. It should return True if the #integer is
malfutka [58]

Answer:

// A optimized school method based C++ program to check  

// if a number is composite.  

#include <bits/stdc++.h>  

using namespace std;  

bool isComposite(int n)  

{  

// Corner cases  

if (n <= 1) return false;  

if (n <= 3) return false;  

// This is checked so that we can skip  

// middle five numbers in below loop  

if (n%2 == 0 || n%3 == 0) return true;  

for (int i=5; i*i<=n; i=i+6)  

 if (n%i == 0 || n%(i+2) == 0)  

 return true;  

return false;  

}  

// Driver Program to test above function

Give the logical function for the following: If cell B7 equals 12, check contents of cell B10. If cell B10 is 10, then the value
ASHA 777 [7]

Answer:

=IF( B7 = 12, ( IF( B10 = 10,"YES", "")), 7) and PRESS ENTER

Explanation:

the above logical if function checks the following

-IF cell B7 is 12, if true, check the value of cell B10, IF cell B10 contains 10 the function should produce YES as output to whatever cell selected, IF B10 is not 10 output of the function should be an empty string, IF B7 is not equal to 12 the the output of the function should be 7.
