An exception is an error that happens during the execution of a program. Exceptions are known to non-programmers as instances that do not conform to a general rule. The name "exception" in computer science has this meaning as well: It implies that the problem (the exception) doesn't occur frequently, i.e. the exception is the "exception to the rule". Exception handling is a construct in some programming languages to handle or deal with errors automatically. Many programming languages like C++, Objective-C, PHP, Java, Ruby, Python, and many others have built-in support for exception handling.
Error handling is generally resolved by saving the state of execution at the moment the error occurred and interrupting the normal flow of the program to execute a special function or piece of code, which is known as the exception handler. Depending on the kind of error ("division by zero", "file open error" and so on) which had occurred, the error handler can "fix" the problem and the programm can be continued afterwards with the previously saved data.
Answer:
b
Explanation:
First, we need to initialize the classifier.
Then, we are required to train the classifier.
The next step is to predict the target.
And finally, we need to evaluate the classifier model.
You will find different algorithms for solving the classification problem. Some of them are like decision tree classification etc.
However, you need to know how these classifier works. And its explained before:
You need to initialize the classifier at first.
All kinds of classifiers in the scikit-learn make use of the method fit(x,y) for fitting the model or the training for the given training set in level y.
The predict(x) returns the y which is the predicted label.And this is prediction.
For evaluating the classifier model- the score(x,y) gives back the certain score for a mentioned test data x as well as the test label y.
<span>A. focus their visual attention on the next point on the road. A driver must have a target, it can be the car in front, a building pr a structure on the road. Targeting enables the driver to look further ahead on the road and thus be ready for any obstacle on the road.</span>
Answer:
The answer is "both voluntary and non-voluntary context switch".
Explanation:
The description to this question can be described as follows:
Whenever processing requires resource for participant contextual switch, it is used if it is more in the situation of I/O tied. In which semi-voluntary background change can be used when time slice ends or even when processes of greater priority enter.
- In option a, It requires voluntary context switches in I /O bound.
- In option b, it requires a non-voluntary context switch for CPU bound.
Answer:
Option a
Explanation:
The Critical Path Method is the arrangement of booked exercises that decides the term of the task. These planned exercises must be performed if the venture is to be viewed as a triumph.
Therefore, options b, c, d and e can't be true because:
b. Activities in the Critical Path Method has no or zero slack.
c. The duration of the critical path in CPM determined on the basis of the latest activity and the earliest initiation.
d. The CPM method schedules the activity of the longest duration.
