Information Systems:

An information system is a system, which provides the necessary information to an organization to achieve goals.

It monitors the transactions details, provide required information to decision makers, and provides necessary documents to the customers.

The main components in an information system include people, data, procedures, hardware, and software.

The main function of information system is to accept and process the input data, and then store the retrieved information and distribute it across the organization.

Explanation of Solution

Principle causes of system quality problems:

The three principle reasons for poor system performance are as follows:

Software threats and faults

Facility disappointments produced by usual or other reasons.

Data quality is poor.

In the software code, no zero defects are achieved because the bugs cannot be estimated...

Explanation of Solution

Four quality of life impacts of computers and information systems:

Balancing Power and Maintaining boundaries

Human jobs are vanished when computers substitute the workers; the tasks become pointless in re-engineered business methods.

Skill to individual and usage of computer creates worsening socioeconomic differences among different cultural people and social classes.

Rapidity of change

The speed of technology is faster than ever before because the time-based competition has an unpleasant side.

The universal market place has condensed the usual social barriers that allowed businesses several years to regulate to competition...

Design a dynamic programming algorithm for the Longest Alternating Subsequence problem described below: Input: A sequence of n integers Output: The length of the longest subsequence where the numbers alternate between being larger and smaller than their predecessor The algorithm must take O(n²) time. You must also write and explain the recurrence. Example 1: Input: [3, 5, 4, 1, 3, 6, 5, 7, 3, 4] Output: 8 ([3, 5, 4, 6, 5, 7, 3, 4]) Example 2: Input: [4,7,2,5,8, 3, 8, 0, 4, 7, 8] Output: 8 ([4, 7, 2, 5, 3, 8, 0,4]) (Take your time with this for the subproblem for this one)

Design a dynamic programming algorithm for the Coin-change problem described below: Input: An amount of money C and a set of n possible coin values with an unlimited supply of each kind of coin. Output: The smallest number of coins that add up to C exactly, or output that no such set exists. The algorithm must take O(n C) time. You must also write and explain the recurrence. Example 1: Input: C24, Coin values = = [1, 5, 10, 25, 50] Output: 6 (since 24 = 10+ 10+1+1 +1 + 1) Example 2: Input: C = 86, Coin values = [1, 5, 6, 23, 35, 46, 50] Output: 2 (since 86 = 46+35+5)

Design a dynamic programming algorithm for the Longest Common Subsequence problem de- scribed below Input: Two strings x = x1x2 xm and y = Y1Y2... Yn Output: The length of the longest subsequence that is common to both x and y. . The algorithm must take O(m n) time. You must also write and explain the recurrence. (I want the largest k such that there are 1 ≤ i₁ < ... < ik ≤ m and 1 ≤ j₁ < ... < jk ≤ n such that Xi₁ Xi2 Xik = Yj1Yj2 ··· Yjk) Example 1: Input: x = 'abcdefghijklmnopqrst' and y = 'ygrhnodsh ftw' Output: 6 ('ghnost' is the longest common subsequence to both strings) Example 2: Input: x = 'ahshku' and y = ‘asu' Output: 3 ('asu' is the longest common subsequence to both strings)
