Suppose the information content of a packet is the bit pattern 1110 0110 1001 1101 and an even parity scheme is being used. What

would the value of the field containing the parity bits be for the case of a two-dimensional parity scheme? Your answer should be such that a minimum- length checksum field is used.

Answer:

\left[\begin{array}{ccccc}1&1&1&0&1\\0&1&1&0&0\\1&0&0&1&0\\1&1&0&1&1\\1&1&0&0&0\end{array}\right]

Explanation:

To keep the checksum length minimum ,checksum field should be a 4x4 matrix with two dimensional even parity bit.

For this purpose first create a matrix of RxC dimensions and add one even parity bit at the end of each row and column.

parity bit is sort of a check flag used to detect errors in binary data.Error detection is done by adding total number of  1's in the binary sequence.

There are two types of parity bits

  1. Even
  2. Odd

For even parity if total number of 1 is even parity bit for that sequence would be (0).

For even parity if total number of 1 is odd parity bit for that sequence would be (1)

For odd parity if total number of 1 is odd parity bit for that sequence would be (0)

For odd parity if total number of 1 is even parity bit for that sequence would be (1)

sergeinik [125]

Answer and Explanation:

Reliability is important because if the service lacks  lacks reliability this could mean losing a packet or acknowledgement which then requires retransmission.

Delay can be tolerable in different degrees by applications, for example online chatting or conferences need to have the minimum delay possible.

Jitter is the variation in delay for packets belonging to the same flow.

High Jitter: difference between delays is large

Low jitter: difference between delays is small.

Bandwidth depends on the application. In video conferences, for example, there is a need to send million of bits per second to refresh a colour screen while sending a email may not reach even a million.
