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.

Q.1 Differentiate between TCP and UDP

Answer:- Reliability :- TCP is more reliable since it manages message acknowledgment and retransmissions in case of lost parts. Thus there is absolutely no missing data. UDP does not ensure that communication has reached receiver since concepts of acknowledgment, time out and retransmission are not present.

Ordering:- TCP transmissions are sent in a sequence and they are received in the same sequence. In the event of data segments arriving in wrong order, TCP reorders and delivers application. In the case of UDP, sent message sequence may not be

Q.2 Describe the features of XML. What are the important rules to keep in mind about the XML declaration?

Answer:-

·         XML files are text files, which can be managed by any text editor.

·         XML is very simple, because it has less than 10 syntax rules.

·         XML is extensible, because it only specifies the structural rules of tags. No specification on tags them self.

·          

·          

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

Answer:- Components of XML processor:-

The profile definitions which follow all assume that the starting point is a well-formed  and namespace well-formed  XML document. This specification does not consider documents that are not namespace well-formed. Documents which are not well-formed are not XML.

Each profile is defined in terms of conformance requirements on processors with respect to various XML-family specifications, and in terms of requirements on the information they provide to applications. Information provision requirements are specified by reference to classes of information items and properties, as further defined in 3 Classes of Information.

Q.4 Describe the procedure of fetching 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 automatically between them from a web browser with a single program for any XML data. In other words, given some data-centric XML data, we can generate a HTML form which can act as a data entry form or a simple low-end web based XML editor. However it is not meant to be a professional XML editor, rather the design goal is an editor that is good for quick entry of small amount of XML data.

Q.5 Describe five different categories of PHP Operators.

Answer: - An operator is something that takes one or more values (or expressions, in programming jargon) and yields another value (so that the construction itself becomes an expression). Operators can be grouped according to the number of values they take. Unary operators take only one value, for example! (The logical not operator ) or ++ (the increment operator ). Binary operators take two values, such as the familiar arithmetical operators + (plus) and - (minus), and the majority of PHP operators fall into this category. Finally, there is a single ternary

Q.6 Describe about 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 script s (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
