Which of the following are recommended techniques for protecting computer files and data? Check all of the boxes that apply.

Answer:

The correct choice is option "A": commit with fallback.

Explanation:

The American scholar Alfred A. Marcus (born 1950) discusses in his book "The Future of Technology Management and the Business" (2015) that hedging can serve as a strategy to protect businesses from the rapidly changing landscape brought on by ongoing technological advancements in the market. As per Marcus, firms should adopt five hedging strategies:

1. Bet on the most likely: focus on the product with the greatest success potential.
2. Follow a robust approach: invest across numerous products.
3. Postpone until more clarity is gained: wait for the appropriate moment to respond to market shifts.
4. Commit with a fallback: adjust according to market conditions.
5. Strive to shape the future: innovate.

Answer:

Since RANDY operates randomly, any file within the specified index range will have the recurrence relation as follows:

T(n) = T(n-i) + O(1)

Here, the probability is 1/n, where i can vary between 1 and n. The variable n in T(n) denotes the size of the index range, which will subsequently reduce to (n-i) in the following iteration.

Given that i is probabilistically distributed from 1 to n, the average case time complexity can then be expressed as:

T(n) =

Next, solving T(n) = T(n/2) + O(1)

yields T(n) = O(log n).

Thus, the complexity of this algorithm is O(log n).

It should be noted that this represents the average time complexity due to the algorithm's randomized nature. In the worst-case scenario, the index range may only decrease by 1, resulting in a time complexity of O(n) since the worst-case scenario would be T(n) = T(n-1) + O(1).
