Answer:
The correct answers are: (A) +/- 5V and (B) +/- 12V
Explanation:
First at all, the purpose of the power supply is transforming from AC (Alternating Current) to DC (Direct Current) for use this energy in chips and electronics devices that consume this type of power. Usually the most common DC voltage for electronics is 5V but in your CPU you also have other devices that might going to need more voltage like fan or hard drives thats ´s why 12V is an also an option. Now some other devices are going to need negative sources such -5V or -12V as well. 
 
        
             
        
        
        
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.

Answer:
a) EDI Semantic Layer 
Explanation:
EDI is an acronym for electronic data interchange and it can be defined as a form of communication between interconnected computer systems and software applications with respect to business informations in standard digital formats.
This ultimately implies that, electronic data interchange (EDI) involves the transfer of business informations such as financial transactions between the computer systems of various organizations such as banks, companies, governmental agencies, etc. Thus, it avails businesses the ability to create strategic communications using computer to computer links to effectively and efficiently exchange business informations electronically or in digital formats.
Hence, the EDI Semantic layer describes the business application that is driving electronic data interchange (EDI).
