Answer:
The following are the code in the Java Programming Language.
//define a class and inherit the other class
public class AlphaChannelColor extends Color {
//define constructor and pass arguments
public AlphaChannelColor(int red, int green, int blue, int alpha) {
super(red, green, blue);
this.alpha = alpha;
}
//define function
public int getAlpha()
{
return alpha;
}
//declare a private type variable
private int alpha;
}
Explanation:
The following are description of the program.
Firstly, define a class 'AlphaChannelColor' that inherits the other class that is 'Color' through the extend keyword. Define the constructor (in Java, the class name and the name of the constructor remain same) and pass four integer data type arguments 'red', 'green', 'blue' and 'alpha' in its parameter. Define the integer data type function 'getAlpha()' that returns the value of the variable 'alpha'.You have just performed a cpm analysis and have found that more than one path through the project network has zero slack values. What can you conclude?
Answer:
There are multiple critical paths
Explanation:
The critical path method (CPM), or critical path analysis (CPA), is an algorithm for scheduling a set of project activities. It is commonly used in conjunction with the program evaluation and review technique (PERT). A critical path is determined by identifying the longest stretch of dependent activities and measuring the time required to complete them from start to finish.
The essential technique for using CPM is to construct a model of the project that includes the following:
A list of all activities required to complete the project (typically categorized within a work breakdown structure), The time (duration) that each activity will take to complete, The dependencies between the activities and, Logical end points such as milestones or deliverable items.
Using these values, CPM calculates the longest path of planned activities to logical end points or to the end of the project, and the earliest and latest that each activity can start and finish without making the project longer. This process determines which activities are "critical" (i.e., on the longest path) and which have "total float" (i.e., can be delayed without making the project longer).
considering the above function of the cpm analysis because you have multiple path, there is tendency that more than path through the project network will have zero slack values.
A CPM analysis showing multiple pathways with zero slack values indicates there are several critical paths in the project, requiring careful management due to lack of buffer time.
If you've performed a CPM analysis (Critical Path Method) and found that more than one path through the project network has zero slack values, you can conclude that there are multiple critical paths. Having zero slack means that any delay in activities on these paths will delay the entire project. Therefore, these paths must be managed carefully as they have no buffer time and are equally critical to the project's timely completion.

While talking to her, you discover that she is trying to work form the break room two floors above the floor where she normally works.
Which of the following is the MOST likely cause of her connectivity problem?
• The user has not yet rebooted her laptop computer while at her new location.
• The user needs a new IP address because she is working on a different floor.
• The wireless network access point on the user's normal floor has failed.
• The user is out of the effective range of the wireless access point on her floor.
• The user has not yet logged off and back on to the network while at her new location.
Answer:
The user is out of the effective range of the wireless access point on her floor.
Explanation:
This user is obviously not close to the access point. As help desk, if a user ever calls to complain about slow speeds or intermittent connectivity while trying to access the network, the first question that you should ask them is how far out are they from the modem or the Access Point. The location between her and the access point might affect the performance of the wireless network. Since she is working from the break room that is two floors above the floor where she normally works, then this means that the walls and ceilings will act as an obstruction to the Wi-Fi signal. The number of Walls and other obstacles will obviously affect the range of the Wi-Fi and will limit the signal’s effectiveness. I will advise the user to go back to her initial working area or be within range to the access point.
