Answer:
Hi there! This question is good to check your knowledge of entities and their relationships. The diagram and explanation are provided below.
Explanation:
The entity relationship diagram for the association between the entities according to the description in the question is drawn in the first attachment. We can further simplify the relationship by removing this many to many relationship between "Chemists" and "Projects" by adding another entity called "Worklist" as detailed in second attachment.
Answer:
a) bytes
b) hertz
c) 1) hertz and 2) bytes
Explanation:
A byte is the basic unit of information and data stored in a computer storage. Hence, the storage capability of a drive will be measured in Bytes. On the other hand speed of processor is measured in terms of number of cycles made per second i.e hertz. Hence, the higher the value of hertz the higher is the speed of the computer.
Answer:
A) True
Explanation:
Objects are known as reference types, meaning that they are always accessed by references, not copied. When a method is called, passing an object to it, Java passes a reference of that object to the method and when that reference is modified, the changes can be seen in the object itself. Therefore a mutable object can be mutated anywhere- either from where it is created or by a method it is passed to. Hence the need to always use privacy modifier keywords such as public, private or protected, to determine the exposure of class properties and methods.
e. /Users/me/Documents/file.txt
Answer:
The correct answer to the following question will be the "Implementation Phase".
Explanation:
The implementation phase encompasses the work performed to accomplish the job range specifications as well as the constitution.
The development team completed the work identified in the schedule during the execution process and made significant improvements whenever the conditions of the project shifted.
There is some objective of this phase, such as:
- Installing and putting the machine into service in the manufacturing environment.
- To ensure that somehow the device meets the practical specifications as created.
So, it's the right answer.
