Answer:
A modem modulates and demodulates electrical signals sent through phone lines, coaxial cables, or other types of wiring.
Answer: b) False
Explanation:
Alternative method that is used for information system consisting of prototyping, outsourcing, end-user development mechanism, system life cycle etc for building a system.
- These process consist of focusing on user requirement, using high level programming languages, development of prototype,creation of package, database etc instead of cross-sectional phase,selection decisions,top management option etc.
- Therefore, the correct option is option(b) as the statement is false.
Answer: True
Explanation:
Subset sum problem and Knapsack problem can be solved using dynamic programming.
In case of Knapsack problem there is a set of weights associative with objects and a set of profits associated with each object and a total capacity of knapsack let say C. With the help of dynamic programming we try to include object's weight such that total profit is maximized without fragmenting any weight of objects and without exceeding the capacity of knapsack, it is also called as 0/1 knapsack problem.
Similar to knapsack problem, in subset sum problem there is set of items and a set of weights associated with the items and a capacity let say C, task is to choose the subset of items such that total sum of weights associated with items of subset is maximized without exceeding the total capacity.
On the basis of above statements we can say that subset sum problem is generalization of knapsack problem.
