Note: Answer all questions. Kindly note that answers for 10 marks questions should be approximately of 400 words. Each question is followed by evaluation scheme.

Q1. Describe the following protocols:

a) IP

Answer : The Internet Protocol (IP) is the principal communications protocol in the Internet protocol suite for relaying datagrams across network boundaries. Its routing function enables internetworking, and essentially establishes the Internet.

IP has the task of delivering packets from the source host to the destination host solely based on the IP addresses in the packet headers. For

b) HTTP

Answer: The Hypertext Transfer Protocol (HTTP) is an application-level protocol for distributed, collaborative, hypermedia information systems. It is a generic, stateless, protocol which can be used for many tasks beyond its use for hypertext, such as name servers and distributed object management systems, through extension of its request methods, error codes and headers. A feature of HTTP is the typing and negotiation of data representation, allowing systems to be built independently of the data

HTTP is designed to permit intermediate network elements to improve or enable communications between

c) FTP

Answer: FTP is a client-server protocol that relies on two communications channels between client and server: a command channel for controlling the conversation and a data channel for transmitting file content.

d) SMTP

Answer: SMTP (Simple Mail Transfer Protocol) is a TCP/IP protocol used in sending and receiving e-mail. However, since it is limited in its ability to queue messages at the receiving end, it is usually used with one of two other protocols, POP3 or IMAP, that let the user save messages in a server mailbox

Q2. a) What are the features of XML? Explain.

b) Describe XML declaration

Answer:The Extensible Markup Language (XML) is a general-purpose markup language. It is classified as an extensible language because it allows its users to define their own elements. Its primary purpose is to facilitate the sharing of structured data across different information systems, particularly via the Internet. It is used both to encode documents and serialize data.

XML is a framework for

Q. 3. List and explain the Components of XML processor.

Answer: When XML is processed, usually there is more to it than one input, on transform, and one output. Rarely is the input in exactly the right format, and rarely can the output be put right where it belongs. And seldom is the transformation which does not require lookups or including data from other sources.

·         XML Processing Control Structures: In addition to being able to route queries by Path, conditions can be forced to emit warnings or even to stop the pipeline with an error. This is valuable where you want to validate some data flowing into or out of steps.

·         XML Processing with Validates: Both Salonika and Excess have produced excellent XML Schema validators, and we let

Q4. Explain how to fetch data from XML to HTML. Give an example

Answer: It is possible to design a HTML form structure such that it embeds all data content and structure of some XML data such that the XML data are displayed in the fields of the HTML form. The HTML form and the XML data are then logically equivalent in terms of the contents of the XML data. It is then possible to convert

Q. 5. Describe five different categories of PHP Operators.

Answer:Operators are a special type of symbols, which are used for calculation and comparison in a programming language. Operators are also used to operate on values. There are six types operators in PHP, which are as follows:

Arithmetic Operators: These operators are used for calculation like add, subtraction, multiplication, division and modulation.

Q. 6. Write short note on ASP.

Answer:ASP is also an abbreviation for application service provider.

An Active Server Page (ASP) is an HTML page that includes one or more scripts (small embedded programs) that are processed on a Microsoft Web server before the page is sent to the user. An ASP is somewhat similar to a server-side include or a common gateway interface (CGI) application in that all involve programs that run on the server, usually tailoring a page for the user. Typically, the script in the Web page at the server uses input received as the result of the user's request for the page to access data from a database and then builds or customizes the page on the fly before sending it to the requestor.
