The Model-View-Controller (MVC) design pattern is a widely used architecture for developing software applications, especially in the context of graphical user interfaces (GUIs). In the MVC pattern, an application is divided into three interconnected components: Model, View, and Controller. This pattern requires that each of these be separated into different objects.

The MVC design pattern is a software architectural pattern that separates the application into three components: Model, View, and Controller. The Model component represents the application's data and business logic. The view is responsible for displaying the data to the user. The Controller component handles user input and manages communication between the model and the view.

When a DNS resolver receives a query for a domain name within a subdomain, it first sends the query to the DNS server for the parent domain (in this case, example.com). The DNS server for the parent domain responds with the name of the authoritative DNS servers for the subdomain, which the resolver can then query directly for the DNS information for the subdomain.

A DNS server is a computer server that contains the database of public IP addresses and their corresponding host names. When a client device requests the IP address for a domain name, the DNS server will respond with the corresponding IP address. There are different types of DNS servers, such as authoritative DNS servers, which store the DNS records for a specific domain, and caching DNS servers, which store recently accessed DNS records to speed up DNS resolution.

String is useful when you need to represent a fixed string value, whereas StringBuffer and StringBuilder are useful when you need to dynamically modify a string value. If you're working with a large amount of string data or need to perform many modifications to a string, StringBuffer or StringBuilder can offer better performance, depending on whether you're working in a multi-threaded or single-threaded environment.
