8 0

Answer:

-80

Explanation:

We have:  1 0 1 1   0 0 0 0

Then we assign to each digit the corresponding power of 2.  

See it in a table:

\begin{matrix}1&0&1&1&0&0&0&0\\2^7&2^6&2^5&2^4&2^3&2^2&2^1&2^0 \end{matrix}

Then multiplying each digit by its corresponding power of 2 and then adding the results, we get:

-2^7+2^5+2^4

Notice the very first digit to the left corresponding to the 2^7 power should be negative according to the format of two’s complement representation.

We get:

-128+32+16=-80

maxonik [38]

Answer: integer overflow

Explanation:

The type of attack has occurred in this scenario is a integer overflow. An integer overflow occurs when there's an attempt by an arithmetic operation to create a numeric value which is outside the range which the given numbers are able to represent.

In this, the integer overflow occurs when the result of the integer operation cannot be able to fit in the allocated memory space which then brings about an unexpected result.

Answer:

C. 2^16

Explanation:

In Computer Networking, there are five (5) classes of IP addresses, these include;

- Class A

- Class B

- Class C

- Class D

- Class E

The various classes of IP address are represented by the value of their first octet. The first octet value of Class B is 128-191 with a subnet mask of 16.

Hence, from the IP address 149.130.x.y where x and y are 8-bit numbers. The x and y equals 16-bit numbers.

Thus, 2^16 devices can connect to the Wellesley network before we run out of IP addresses.
