Answer:
Let's take an example of the embedded system, which is a perfect example of this question as a computer system. Suppose we want the embedded system to record the details related to soil of agricultural land. We will take an IoT device which will be a sensor that can register soil properties, and get connected to the computer system through the internet. And we design an embedded system that registers these values and then copy them like somewhere in DB space on Amazon cloud or Google cloud. And finally display on some LCD or a big projector, or whatever, and like we design. Thus we have designed, and now when we install this on agriculture land, we implement it, and since check regular for correct performance, we maintain this embedded or a mini-computer system as well. This is what design, implement and maintain computer systems mean.

Answer:
a. True
b. False
Explanation:
Constructor is used to initialize the object of the class.
Rules of constructor:
1. Constructor name must same as the class name. it means, if the class name is animalType, then constructor name must be animalType.
2. Constructor does not have any return type. it means, it does not return anythings.
Therefore, part (a) is true, Constructor name must same as the class name.
and part (b) is false, because constructor does not have any return type.
Answer: B. Spreadsheet
Explanation:
In order to assess the impact from an increase or decrease in price and / or sales , is more useful to use an spreadsheet, because, even though it store values in cells, in the same way that a database could do in fields , the spreadsheet can link the values with more flexibility, using different formulae, trying different scenarios, 'what if" type questions, etcetera, not so easy to do with databases.
