Web Technologies Question 1:
Which of the following is a software responsible for accepting HTTP requests from clients and providing HTTP responses?
Answer (Detailed Solution Below)
Web Technologies Question 1 Detailed Solution
- A Web server is a software/Hardware responsible for accepting HTTP requests from clients, which are known as Web browsers, and serving them HTTP responses along with optional data contents, which usually are Web pages such as HTML documents and linked objects (images, videos, etc.).
- The term web server can refer to hardware or software, or both of them working together.
- On the hardware side, a web server is a computer that stores web server software and a website's component files. (for example, HTML documents, images, CSS stylesheets, and JavaScript files) A web server connects to the Internet and supports physical data interchange with other devices connected to the web.
- On the software side, a web server includes several parts that control how web users access hosted files. At a minimum, this is an HTTP server. An HTTP server is a software that understands URLs (web addresses) and HTTP (the protocol your browser uses to view webpages). An HTTP server can be accessed through the domain names of the websites it stores, and it delivers the content of these hosted websites to the end user's device.
Web Technologies Question 2:
Which of the following is true, according to the .NET programming language?
i. Reference type variables are stored in the heap.
ii. Value type variables are stored in the stack.
iii. In unboxing, a value type is converted to object type.
Answer (Detailed Solution Below)
Web Technologies Question 2 Detailed Solution
Option 1: Reference type variables are stored in the heap.
True, Reference Type variables are stored in a different area of memory called the heap. This means that when a reference type variable is no longer used, it can be marked for garbage collection.
Examples of reference types are Classes, Objects, Arrays, Indexers, Interfaces, etc.
Option 2: Value-type variables are stored in the stack.
True, Value Type variables are stored in the stack. A Value Type stores its contents in memory allocated on the stack. When you created a Value Type, a single space in memory is allocated to store the value and that variable directly holds a value.
Option 3: In unboxing, a value type is converted to an object type.
False, Boxing is the process of converting a value type to the type object or to any interface type implemented by this value type. When the common language runtime (CLR) boxes a value type, it wraps the value inside a System. Object instance and stores it on the managed heap. Unboxing extracts the value type from the object.
Hence the correct answer is only I and ii.
Web Technologies Question 3:
To declare the version of XML, the correct syntax is:
Answer (Detailed Solution Below)
Web Technologies Question 3 Detailed Solution
Concept:
XML stands for extensible markup language which lets you define your own tags in the order they occur. It is derived from SGML (Standard Generalized markup language).
Explanation:
XML is a platform-independent language. It is used to store and organize the data. The first line in the XML document is the XML prolog which includes XML declaration, DOCTYPE, version and comments. XML documents must contain a root element. In XML1.0, all things in the prolog are optional while for version 1.1, declaration is required in the prolog.
Syntax for declaring the version of XML is :
xml version = "1.0" ?>
XML is slightly different from HTML. In html, we have predefined tags, while in XML we have to define our own tags. XML .XML is used for storing and transporting the data. Using the XML sharing of data between two programs on different platforms is possible.
