what could a manager use to measure the success of an mis project?

Answers

A manager can use several key performance indicators (KPIs) to measure the success of a Management Information System (MIS) project. These KPIs include:

1. Return on Investment (ROI): Calculate the financial returns on the investment made in the MIS project, comparing the benefits to the costs.

2. Project Completion Time: Assess whether the project was completed within the planned timeframe, and identify any factors that led to delays or accelerations in the schedule.

3. User Adoption Rate: Track the percentage of users who have embraced the new system and are actively using it, as a high adoption rate suggests the project's success.

4. Data Accuracy: Ensure the data generated by the MIS is accurate and reliable, as this contributes to effective decision-making.

5. System Efficiency: Measure the improvements in operational efficiency, such as reduced processing times and increased automation, brought about by the MIS.

6. User Satisfaction: Gather feedback from users to evaluate their overall satisfaction with the MIS and its impact on their work processes.

how many usable host addresses exist within a network with a cidr prefix of /23

Answers

A CIDR prefix of /23 indicates that the network has a total of 23 bits assigned for the network portion of the IP address.

This means that the remaining 9 bits (32 - 23 = 9) are used for the host portion of the IP address. With 9 bits assigned for the host portion, there are 2^9 possible combinations or 512 possible host addresses for this network.

However, not all of these 512 host addresses are usable as some are reserved for network and broadcast addresses. The network address represents the first address in the network and is used to identify the network itself, while the broadcast address represents the last address in the network and is used to send a message to all hosts on the network.

Therefore, the usable host addresses within a network with a CIDR prefix of /23 are the total number of host addresses minus 2 (network address and broadcast address), which is equal to 510 usable host addresses.

It's important to note that the number of usable host addresses can vary depending on the specific network configuration and allocation of IP addresses. However, this calculation provides a general understanding of how many usable host addresses exist within a network with a CIDR prefix of /23.

Assume you are given an int variable named nPositive and a two-dimensional array of ints that has been created and assigned to a2d. Write some statements that compute the number of all the elements in the entire two-dimensional array that are greater than zero and assign the value to nPositive.

Answers

Answer:

public class Main

{

public static void main(String[] args) {

    int nPositive = 0;

    int[][] a2d = {{-7,28, 92}, {0,11,-55}, {109, -25, -733}};

 for (int i = 0; i < a2d.length; i++) {

                  for(int j = 0; j < a2d[i].length; j++) {

         if(a2d[i][j] > 0){

             nPositive++;

 System.out.println(nPositive);

}

}

Explanation:

*The code is in Java.

Initialize the nPositive as 0

Initialize a two dimensional array called a2d

Create a nested for loop to iterate through the array. If an element is greater than 0, increment the nPositive by 1

When the loop is done, print the nPositive

const a2d =  [[7,28, 92], [0,11,-55], [109, -25, -733]];
