Explanation of Solution

CPU (Central Processing Unit):

  • CPU is called as the Heart of a Computer, because it stores and retrieves data.
  • It is the component of the computer which is responsible for executing many commands.
  • CPU contains two parts namely: Control unit and Arithmetic Logic Unit.
  • It is mainly used to get the instructions as well as to perform the mathematical operations.

Explanation for incorrect options:

Memory is a storage location of data which can be accessed directly.

Hence, the option “A” is wrong.

When the data is stored using any external memory device whose contents are non-volatile in nature are termed as “Secondary storage”.

Hence, the option “C” is wrong.

When the data is collected from the user through any device is called as input device.

Hence, the option “D” is wrong.

(Dynamic Programming.) Recall the problem presented in Assign- ment 3 where given a list L of n ordered integers you're tasked with removing m of them such that the distance between the closest two remaining integers is maxi- mized. See Assignment 1 for further clarification and examples. As it turns out there is no (known) greedy algorithm to solve this problem. However, there is a dynamic programming solution. Devise a dynamic programming solution which determines the maximum distance between the closest two points after removing m numbers. Note, it doesn't need to return the resulting list itself. Hint 1: Your sub-problems should be of the form S(i, j), where S(i, j) returns the maximum distance of the closest two numbers when only considering removing j of the first i numbers in L. As an example if L [3, 4, 6, 8, 9, 12, 13, 15], then S(4, 1) = 2, since the closest two values of L' = [3,4,6,8] are 6 and 8 after removing 4 (note, 8-6 = = 2). = Hint 2: For the sub-problem S(i, j),…
