Answer:

This will result in a compilation error.

Here's the inheritance hierarchy:

Meg -> Lois -> Brian -> Stewie

Now Meg has 2 public Fxns, a() and toString().

Lois inherits from Meg and all its public functions as well but, overrides the a() fxn of its super class.

So finally Lois has fxns a(), b() and toString().

Brian extends Lois and inherits all the above listed fxns of Lois, but overrides the b() and toString() fxns.

Stewie extends Brian and inherits all the fxns of Brian, but overrides the a() and toString() fxns.

In the Main driver fxn, we call a() and b() methods of all these classes but, the base class Meg has no b() and it is not extending any class so its not available in its scope.

This results in a compilation error.

Consider a classful IPv4 address 200.200.200.200? What is its implied subnet mask? If we take the same address and append the CI

topjm [15]

Answer:

a. 255.255.255.0 (class C)

b. 255.255.255.224

Explanation:

Here, we want to give the implied subnet mask of the given classful IPV4 address

We proceed as follows;

Given IPv4 address: 200.200.200.200

Classes

Class A : 0.0.0.0 to 127.255.255.255

Class B: 128.0.0.0 to 191.255.255.255

Class C: 192.0.0.0 to 223.255.255.255

Class D: 224.0.0.0 to 239.255.255.255

so 200.200.200.200 belongs to Class C and it's subnet mask is 255.255.255.0

In CIDR(Classless Inter Domain Routing)

subnet /27 bits means 27 1s and 5 0s. so subnet

i.e 11111111.11111111.11111111.11100000 which in dotted decimal format is 255.255.255.224 .

A string that contains only 0s,1s, and 2s is called a ternary string. How many strings of 10 ternary digits (0, 1, or 2) are the

alexdok [17]

Answer:

Number of strings = (10, 2)×(8,3) = 2520

Explanation:

The number of possible combinations for taking two 0's is C(10, 2)

It remains 8 Positions

The number of possible combinations for taking three 1's is C(8,3)

So there remains 5 spots
