Your customer, Maggie, wants to buy a gaming PC, and she specifically mentions that she wants an Intel CPU and intends to overcl

Ksenya-84 [330]

Answer:

Intel produces a series of unlocked CPU's that can be overclocked. These CPUs are from the "K" or "X" series. Example: Intel Core i9-9900K, Intel Core i9-10940X.

These are the few things that are to be kept in mind while overclocking:

-Motherboard: Motherboard should support overclocking. Example: Intel Z series, most AMD motherboards.

-Cooler: Boosting the clock speed increases the temperature. The cooler has to be upgraded to keep the temperatures low. Example: Water-cooled. Also, the heat sink has to be checked if it's working properly.

-Be ready to test your system in BIOS. Make sure the temperature, voltage, memory speed is stable for the set clock speed.

Which of the following are incorrect? Group of answer choices An interface can contain constructors. You may declare a final abs

spin [16.1K]

Answer:

Explanation:

1. The answer is No, interface cannot have constructors. ... In order to call any method we need an object since there is no need to have object of interface, there is no need of having constructor in interface (Constructor is being called during creation of object).

2.A final class is considered complete and can not be subclassed (It's methods can not be overridden ). In case of abstract class, we have to proved implementation to abstract methods in subclasses. A final class can not have abstract methods and an abstract class can not be declared final.

3.private constructors are acceptable, however the class should be marked final instead, as doing so means the class is to be extended.

4.Yes! Abstract classes can have constructors! Yes, when we define a class to be an Abstract Class it cannot be instantiated(i.e an object cannot be created) but that does not mean an Abstract class cannot have a constructor. Each abstract class must have a concrete subclass which will implement the abstract methods of that abstract class.

Which of the following statements is NOT a valid way to create a date object named birthday?

dem82 [27]

Answer:

var birthday = "12/2/1978";

Explanation:

It does not create a date object named birthday because in this statement the birthday is a string which contains 12/2/1978 a date it is not date object it is a string.All other three options are correct way to create a date object.

var birthday = new Date();

creates a date object with the current date and time.

we can also pass date string in the new Date().So var birthday = new Date("12/2/1978"); is also correct.

we can also pass year,month,day in new Date() In this order only.So option fourth is also correct.
