7.4.1C The global distribution of computing resources raises issues of equity, access, and power. Briefly describe one of these
nika2105 [10]

It has been accentuated. An organization is a system consisting of: people, material resources and information, being the last, the nerve center of the previous two that allows the survival of these. This statement refers to the most recent conceptions defended by the Information Management (IM), in the sense that organizations should be considered primarily as information systems.

Lynda Woodman's definition of IM states that "management is everything that refers to obtaining the right information, for the right person, at the right price, at the right time and place, to make the right decision."

As for the MIR, part of the assumption of recognition that information is a resource, a value that should be managed like any other, because among the similar characteristics we have:

* acquired at a cost and chargeable in money

* has specific and measurable characteristics

* control of the cost of information,

* has a life cycle,

* ability to be processed and refined, etc.

For Elizabeth Adams "the MIR is a function of top management, to develop a series of policies, programs and procedures to effectively and effectively plan, manage and control the information needs and support resources of information management." In this directive task, the components that participate and the areas in which the person responsible for it must operate are:

1.- information resources: that is, identification, evaluation and use of these, not only internal but also external.

2.- Appropriate technology: to collect, store, retrieve or disseminate information.

3.-management: general planning, human resources, communication, accounting and marketing.

In today's world, there is a tendency to grant special treatment to everything that is related to information; and it is this situation that gives rise to the importance of the management / management of information resources (MIR).

This era of information, characterized as significant changes, flexibility, uncertainty and the "great battles" (for competitiveness, leadership, competition, reduction of uncertainty and risk, etc.), it is necessary to keep updated as soon as to the significant changes that occur in the technology of products and processes, as well as in their management and competitiveness patterns.

We live in an era where the common denominator of progress will be the wise application of information, science and technology, in the production of goods and services for the satisfaction of social needs, as well as the adequate use of resources to increase the wellbeing of society and man. In others, words, we are talking about the correct management of information.

Information management is the new name of the development. Are the professionals (librarians, documentalists) ready to accept the challenge? We believe that information professionals are in an adequate situation, have knowledge, resources, capacity and conditions to maintain a sustainable leadership in the organization of information, but they have to determine what they believe their position should be and fight for it. We must start from the basic criteria, restructure the concept of the information scientist to adapt it to the new, complex and changing needs of the organization and the community.

Write a java program to read elements in an array from user and count total number of duplicate elements in array.
Anna11 [10]

Answer:

Explanation:

The following code is written in Java and is a function/method that takes in an int array as a parameter. The type of array can be changed. The function then creates a counter and loops through each element in the array comparing each one, whenever one element is found to be a duplicate it increases the counter by 1 and moves on to the next element in the array. Finally, it prints out the number of duplicates.

public static int countDuplicate (int[] arr) {

               int count = 0;

               for(int i = 0; i < arr.length; i++) {

                       for(int j = i + 1; j < arr.length; j++) {

                               if(arr[i] == arr[j])

                                       count++;

                       }

               }

               return count;

       }

Draw a timeline for each of the following scheduling algorithms. (It may be helpful to first compute a start and finish time for
12345 [234]

Answer:

See explanation below

Explanation:

Previos concepts

First Come First Serve (FCFS) "is an operating system scheduling algorithm that automatically executes queued requests and processes in order of their arrival".

Shortest job next (SJN), or the shortest job first (SJF) or shortest "is a scheduling policy that selects for execution the waiting process with the smallest execution time".

Shortest remaining time (SRF) "is a scheduling method that is a preemptive version of shortest job next scheduling'".

Round robin (RR) is an algorithm where the time parts "are assigned to each process in equal portions and in circular order, handling all processes without priority"

Solution for the problem

Assuming the dataset given on the plot attached.

Part a

For this algorithm the result would be:

Job A   0-6

Job B   6-(6+3) = 6-9

Job C   9-(9+1) = 9-10

Job D   10-(10+4) = 10-14

Part b

For this algorithm the result would be:

Job A   0-6

Job C   6-(6+1) = 6-7

Job B   7-(7+3) = 7-10

Job D   10-(10+4) = 10-14

Part c

For this algorithm the result would be:

Job A   0-1  until 14

Job B   2-(2+3) = 2-5

Job C   3-(3+2) = 3-5

Job D   9-(9+5) = 9-14

Part d

For this algorithm the result would be:

Job A   0-2 , 7-9, 12-14

Job B   2-4, 9-10

Job C   4-(4+1) = 4-5

Job D   5-7, 10-12

Telnet conversations are not encrypted, whereas ssh conversations are, so ssh is secured against eavesdropping.
