Answer:
PLCs (Programmable logic controller) were original designed as replacement for relay control panels. Relay is another word for a switch. Relay control panels were made for the control of electronic instrumentents or devices. Later on PLCs were made to replace these timers and relay control panels. PLCs are more reliable, flexible and can work better in the harsh environmental situations then the relay control panels.
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.
Answer:
B) ERP systems
Explanation:
ERP which means Enterprise Resource Planning is a software that uses a centralized database, it helps to hasten business processes thereby reducing the use of manual labour. Some of the integrated software modules which it provides are:
*Finance, Accounting.
*Human resource.
*Manufacturing and production.
*Sales and marketing.
The ERP system does not really need the total involvement of a human because it has a database where information stored is used in the daily execution of tasks, it can also be used to measure the productivity and profitability of the business.
Answer:
many-to-many relationship
Explanation:
They are different types of relationship between projects. A many-to-many relationship occurs when a row in a table associates with many related rows in another table. For example the relationship between an employee and a project, An employee can work on many projects and a project can have many employees working on it.
