Answer:
<u>the first friend</u>
Explanation:
It is important to <em>remember </em>that a core is the brain of the CPU (central processing unit), which means one who has a dual-core is having <em>"a dual brain" </em><em>to process information faster.</em>
Consider also, IT experts often acknowledge that in terms of speed of execution, it is proven that, "dual-core systems" are <em>faster</em> (even twice faster) than a "single-core system". The other friends were wrong because they disagreed with a widely accepted fact that dual-core is faster than single-core; and of course, <em>we know that without them being faster they can't run twice the applications and twice the data. </em>
Therefore, we can make the conclusion that the first friend's response is correct.
The statement that completes the query is: bytes / 1000 AS kilobytes
<h3>SQL (Structured Query Language)</h3>
This is the language that is used to retrieve, update, and store data in the database.
<h3>Columns</h3>
From the question, we have the following table columns
- track_id
- track_name (name of the music track)
- composer
- bytes (digital storage size of the music track
To retrieve data from the bytes column, we make use of:
SELECT bytes ......
From the question, we understand that this column should be divided by 1000, and the AS command should be used.
So, the query becomes
SELECT bytes / 1000 AS kilobytes .....
Hence, the statement that completes the query is: bytes / 1000 AS kilobytes

<u>Answer:</u>
<em>Black and white</em>:
It has only two values namely black or white. The white colour in the image will be represented as “white” and other colour part will be displayed as black.
<em>Grey-scale: </em>
Again the white part does not have a change, the black and other coloured items will be displayed in grey.
<em>Coloured image: </em>
It would display the actual colour of the image. The number of colours and shades depends on the original image from where actually it has been shooted and it also depends on the quality of the camera.
In python the input() function prompts the user to enter information.
Answer:
All are True
Explanation:
a. A constructor must have the same name as that of a class. For example
public class MyFirstClass{ // this is the class name
public MyFirstClass() } // the constructor having the same name as class.
b. Constructors never have a return type not even void because it is only used to initialize the values of data members of the class when the object of the class is created so constructors are not directly called hence they do not need to have a return type.
c. Constructors are invoked using the new operator.
When the new object is created the constructor is invoked in order to initialize the variables of a class. The memory is allocated to the object and then the constructive is invoked for the purpose to initialize the object.
