Answer: a) N² files. b) 2N files.
Explanation:
if an user can choose freeely both the video and the audio quality, if they are stored separately, but the user can download any mix of them as a single file, the server must store one audio version for each video version, so it will need to store NxN = N² files.
If, instead, the server can send the audio and video streams separately, so the user can choose one of the N video available, and one of the N audio versions, the server will need to store only N video files + N audio audio files, i.e. , 2 N files.
TCP and router system is the best fitting answer.
<u>Explanation:</u>
In network TCP IP address plays major roles. Without TCP even network will not work. To access the internet we need TCP address. TCP is required to send an email or chatting software or VPN connectivity. To get access or connect computer or desktop or workstation TCP plays major roles.
To send an email id we need from address and to address at the same time to send mail we need TCP and their router systems. To check whether we are connected to network router we use PING command in DOS MODE for that TCP IP address is required.

Explanation:
// Code to copy
public class ConstChain1 {
public static void main(String[] args)
{
new SubClass();
System.out.println();
new SubClass(1);
}
}
class SuperClass{
public SuperClass() {
System.out.println("D");
}
public SuperClass(int i) {
System.out.println("C");
}
}
class SubClass extends SuperClass{
public SubClass() {
this(10);
System.out.println("B");
}
public SubClass(int i) {
super(i);
System.out.println("A");
}
}
Explanation:
Now each time when a object of a subclass is been created it's super class constructor will be executed first then only subclass object is created by executing it's constructor.
