Answer:

Compression is hard since we usually find it difficult to determine the best compression rate .

When using the text compression widget we make a key that represent every work we have repeated in order to decrease the stored data.

When you have extends you compression beyond what it should be it is easy to notice since there will be no algorithm and that makes it hard hence we end up making assumptions on what ratio we will use for compression by using a thorough key.

A technician is dispatch to troubleshoot a user's computer.
Margarita [4]

Answer:

All of the above.

Explanation:

Thrashing or drive or disk thrashing occurs when the hard drive is stressed with transferring information between the system memory and virtual machine excessively. In thrashing, there is a large number of processes running in the system and the system memory is too small to handle all processes. Thrashing leads to decreased system performance and hard disk failure.

To stop the impact of thrashing, install more RAM, end unimportant progam processes etc.

The Subset Sum problem is a generalization of the Knapsack problem. Group of answer choices True False g
Katarina [22]

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.
