Explanation:
1
R is many - many;
in this case we have that E1 is not what should be used to determine E2 and in this same way, W2 is not what should determine E1. So non of these can be a key on its own.
2.
R is many-one from E1 to E2
in this case there are 2 tuples (f1,f2) and (e1,e2) which have to be the same if they have the same key attribute for E1. All of them are the same so all the pairs are the same.
3.
R is many-one from E2 to E1:
the explanation for this is is almost the same with that of b. we apply the same logic. since for all keys, all pairs and sets are the same.
4.
R is one-one:
E1 is what determines E2 and likewise, E2 is what determines E1. irrespective of the key that is used, key K is going to the same value of n.
Answer:
WAIT
Explanation:
Based on the information provided within the question it can be said that the processor server puts the process in a WAIT state. In other words it temporarily pauses the server from taking any action until the message from the service request comes back with a response. Once that happens it receives new instructions and is resumed.
The CLI is the main, text-based interface for setup, administering, and checking network tools such as a router or a switch hub. CLI allows you to transcribe in composition commands to get the output from the router or a switch hub. The network application software recognizes the command when you input the exact characters of the command to essentially identify it, which in turn helps you check the status of your network device.
The method calcPyramidVolume is an illustration of the java methods; where the methods are executed when called or evoked
<h3>The main program</h3>
The program written in Java, where comments are used to explain each action is as follows:
//This defines the calcPyramidVolume method
public static double calcPyramidVolume(double baseLength,double baseWidth, double pyramidHeight) {
//This calculates the volume of the pyramid
double PyramidVolume = calcBaseArea(baseLength,baseWidth) * pyramidHeight;
//This returns the volume of the pyramid
return PyramidVolume;
}

Because an IDLE itself runs in a thread, it is not generally a good idea to test a multithreaded application in that environment. is a true statement.
<h3>What is a multithreaded application?</h3>
A multi-threaded application is known to be a kind of application that is made up of structure which make use of the multi-threading that is given by the operating system.
Note that due to the fact that an IDLE itself runs in a thread, it is not is said to be a good idea to test a multithreaded application in that environment as one can be able top get a good result.
