Question

1. Assume that a bit sequence "10000000" has been transmitted through a transmission media using parity bits. Two bits have been altered in the path and the receiver has received it as "10000011". will the receiver be able to detect the error. Justify your answer.

2.Which of the following is NOT a consequence of poor project management?

a. Time slippage.

b. Loss of intellectual property.

c. Failure to obtain anticipated benefits.

d. Costs that exceed budgets.

3. Simon's software company has developed a search engine algorithm 200% more efficient than Google's.

Which intellectual property protection should Simon's company use in order to protect the algorithm? Justify your answer. Enter your answer below.

4.Sarah owns an IT company. She has a prospective client (owner of a small business) who wants to build website and online store for the business. The client is vague about his requirements as he is not totally sure what he requires. What systems build method would be appropriate in this instance? Justify your answer. Enter your answer below.

Answer 1

1. According to the given question, transmitted bit sequence is 10000000 and after altering two bits due to some error, the receiver received it as 10000011, so there is two consecutive bit error in the codeword during transmission. It can be detected using Hamming code technique. Hamming code is a block coding technique for single bit error correction and two simultaneous bit error detection of the codeword to be transmitted. After placing the redundant bits correctly along with the data word we get the codeword to be transmitted. Then for double bit error detection, we need to add one additional parity bit at the Most Significant Bit (MSB) position, this bit is nothing but the XOR of all other bits of the codeword. But, in this technique this double bit error can be detected, but it can not be corrected.

2. From the given options, the option which is not a consequence of poor project management is -

b) Loss of intellectual property.

3. To, protect the algorithm, the company needs to assure that no other company can claim about the ownership of the intelectual properties of the company. They must not discuss or share anything about these with any outsider informally. A clear ownership statement of all intelectual properties and confidentiality agreement must be maintained.  Besides these, most importantly they need to issue a patent of their algorithm for the search engine, and issue copyright and trademark right of their algorithm.
