Answer:
A unique identifier for a mobile phone
Explanation:
There are different codes and tracking number assigned to different devices such as laptop, mobiles and other devices. The purpose of this task is to make sure the security of device in all aspects. The tracking number that is used to track mobile phone is named as IMEI that stands for International Mobile Equipment Identity.
IMEI is the the unique identity of mobile phone device that consists of 15 digits. It is the unique number that is assigned to phones.
Answer:
The class is called MyApp which inherits from JFrame and implements the ActionListener interface.
Explanation:
The class is called MyApp which extends the swing class JFrame and implements the ActionListener interface for event handling. As a results it needs to implement a method called actionPerformed for handling the relevant events that may be raised from the user interface. Since it extends JFrame, it has access to all the public and protected methods defined in JFrame(for example setTitle to set the title of the frame).
Answer:
Its the printer. The details shown on screen can be tested on monitor using the software like PDF and word processor. And from there you can format and finally get the hard copy of the document via printers.
Explanation:
Various kinds of the printers are available. And all of them take the text and pictures on the computer screen, and then print that on the paper. The details are in the answer section. And some of the examples of the printers are like dot matrix printer, laser printer etc.

Explanation:
All website around the world/internet is a collection of different web pages, HTML can be referred to as the single most essential standard when it comes to web design, as well as it being the only one that’s enormously required or needed if you plan to create a web page.
to answer the question above, we will be creating an HTML document that describes nested ordered lists of cars, kindly check the attached images below to see the written codes to solve the question.
Big-O notation is a way to describe a function that represents the n amount of times a program/function needs to be executed.
(I'm assuming that := is a typo and you mean just =, by the way)
In your case, you have two loops, nested within each other, and both loop to n (inclusive, meaning, that you loop for when i or j is equal to n), and both loops iterate by 1 each loop.
This means that both loops will therefore execute an n amount of times. Now, if the loops were NOT nested, our big-O would be O(2n), because 2 loops would run an n amount of times.
HOWEVER, since the j-loop is nested within i-loop, the j-loop executes every time the i-loop <span>ITERATES.
</span>
As previously mentioned, for every i-loop, there would be an n amount of executions. So if the i-loop is called an n amount of times by the j loop (which executes n times), the big-O notation would be O(n*n), or O(n^2).
(tl;dr) In basic, it is O(n^2) because the loops are nested, meaning that the i-loop would be called n times, and for each iteration, it would call the j-loop n times, resulting in n*n runs.
A way to verify this is to write and test program the above. I sometimes find it easier to wrap my head around concepts after testing them myself.
