For each user who comes to your site the google analytics automatically capture the traffic source dimensions Source, Medium, Campaign name.
<u>Explanation:</u>
Source:
- There cannot be any reference to a website without an origin source.
- The source is basically the origin of your traffic such as a search engine (google) or a domain (ex: Twitter).
Medium:
- Every referral to a website also has a medium along with the source.
- examples are -: unpaid search, "cost per click", referral, mail.
Campaign name:
- The campaign Name is the name referring to the google ads campaign.
Answer:
Explanation:
When most non-technical people hear the term “seven layers”, they either think of the popular Super Bowl bean dip or they mistakenly think about the seven layers of Hell, courtesy of Dante’s Inferno (there are nine). For IT professionals, the seven layers refer to the Open Systems Interconnection (OSI) model, a conceptual framework that describes the functions of a networking or telecommunication system.
The model uses layers to help give a visual description of what is going on with a particular networking system. This can help network managers narrow down problems (Is it a physical issue or something with the application?), as well as computer programmers (when developing an application, which other layers does it need to work with?). Tech vendors selling new products will often refer to the OSI model to help customers understand which layer their products work with or whether it works “across the stack”.
Layer 7 - Application
To further our bean dip analogy, the Application Layer is the one at the top--it’s what most users see. In the OSI model, this is the layer that is the “closest to the end user”. It receives information directly from users and displays incoming data it to the user. Oddly enough, applications themselves do not reside at the application layer. Instead the layer facilitates communication through lower layers in order to establish connections with applications at the other end. Web browsers (Google Chrome, Firefox, Safari, etc.) TelNet, and FTP, are examples of communications that rely on Layer 7.
Layer 6 - Presentation
The Presentation Layer represents the area that is independent of data representation at the application layer. In general, it represents the preparation or translation of application format to network format, or from network formatting to application format. In other words, the layer “presents” data for the application or the network. A good example of this is encryption and decryption of data for secure transmission - this happens at Layer 6.
2 4 9
Explanation:
Basically what I thought was the way was, since 2 is first, then its 1, then since 4 is second, it's added second, lastly to get the last oneI added them all and got 9 so that's third.
Answer: Constructors can specify parameters but not return types.
Explanation:
public class Student {
int roll_no;
public Student(int a) {
roll_no = a;
}
public static void main(String[] args) {
Student abs = new Student(10);
System.out.println(abc.roll_no);
}
}
In the above code we have illustrated the working of constructors. We have a class with the name Student. then a constructor is created of the class called as the class constructor. In the main we create an object of the class and with this object we invoke the constructor and also pass a parameter. Here in the code we are passing the roll no of the student.
So we can say that constructor is called during the runtime when the object created invokes the constructor so a constructor can have many arguments but it does not have a return type.
