Client/Server and Peer-to-Peer networks are the two major network architecture models in use today. They each have advantages and disadvantages that can be used to benefit a particular outcome.
Briefly, the client/server model relates to one or many client performing relatively simple requests, which are then executed by a server. The server is performing more complex tasks, and often interacting with many clients simultaneously. Examples of client/server models include most websites, including the Brainly page you are running right this instant. Your web browser is acting as a client, and the Brainly.com website is running as a web server. It receives simple requests or information from your browser, such as clicking on a question or text typed by your keyboard, and then acts on this information by consulting a database, returning values, or returning a whole new web page to your browser. The client/server model is very powerful in business as it allows powerful and secure server-side processing and relatively simple clients. Office 365 that runs all microsoft office suites such as word and excel in a web browser on 'the cloud' is an example of a highly sophisticated client/server architecture.
By contrast, peer-to-peer networks are a distributed architecture of equals. Instead of a simple client and complex server, all clients are equals and link together to form nodes on a distributed network. There is no central control (server) and each node acts as a client and server to other nodes. This is also an extremely powerful network; as there is no central control it is difficult to shut down a peer-to-peer network. Taking out one node will not break the network in comparison to the client/server architecture where if the server goes down, services halt. Prime examples of famous peer-to-peer networks are the Bitcoin network and similar cryptographic currency networks, and music and file sharing networks such as Torrents. The torrent tracker websites are client/server however once a torrent is loaded into a torrent downloading application, the file is collectively downloaded from hundreds of 'peers' across the world as part of the torrent peer-to-peer network.
Answer:
4.01 version .
Explanation:
A hypertext Markup language is used for designing the web page when we added the CSS on the web page we can create the web page more efficient manner and also there is more control over the web page because we can easily call the classes of CSS.
The Hypertext Markup language version 4.01 provides greater flexibility on the web page also We can also control the page layout in a very easy manner. The appearance of the web page is good as compared to version HTML 4
Answer:
By using the this keyword
Explanation:
The this keyword in java is used for pointing the current object or current variable .The this keyword is removing the ambiguity among the characteristics of the class as well as the variables with the similar name.
In the given question if the class student has member variable gpa also we have a method having the argument gpa with the help of this keyword we can refer the gpa variable inside the method .
Following are the implementation of the given question
public class Main // main class
{
int gpa; // variable declaration
public Main(int gpa) // constructor
{
this.gpa = gpa; // this keyword
}
public static void main(String[] args) // Main method
{
Main m= new Main(55); // creating object of class
System.out.println("The Value of gpa is : " + m.gpa); // display value
}
}
Output:
The Value of gpa is :55
