1. What is web 2.0?

A Web 2.0 site may allow users to interact and collaborate with each other in a social media
dialogue as creators of user-generated content in a virtual community, in contrast to Web sites
where people are limited to the passive viewing of content. Examples of Web 2.0 include social
networking sites, blogs, wikis, folksonomies, video sharing sites, hosted services, Web
applications, and mashups.

2. Define Web services.

A Web service is a method of communication between two electronic devicesover a network.
It is a software function provided at a network address over the Web with the service always
on as in the concept of utility computing.

3. Define Website.
A website is hosted on at least one web server, accessible via a network such as the Internet or
a private local area network through an Internet address known as a uniform resource locator
(URL). All publicly accessible websites collectively constitute the World Wide Web

4. Differences between web sites and web server. Website:

A website is a set of linked documents associated with a particular person, organization or
topic that is held on a computer system and can be accessed as part of theworld wide web.
(Not to be confused with:Web page, a document on the world wide web written in HTML and
displayed in a web browser.)
Web server:The web server on the other side is a computer program, which delivers content,
such as websites or web pages, for example, over the world wide web from a web server to
your computer.

5. Define internet.
The Internet is a global system of interconnected computer networks that use the standard
Internet protocol suite (TCP/IP) to link several billion devices worldwide. It is a network of
networks that consists of millions of private, public, academic, business, and government
networks of local to global scope, linked bya broad array of electronic, wireless, and optical
networking technologies.
6. Define HTML.
HTML is a simple web page description language, which enables document creation for the web.
HTML is the set of mark-up symbols or codes placed in a file intended for display on the web
browser page. These mark-up symbol and codes identify structural elements such as
paragraphs, heading, and lists. HTML can be used to place media (such as graphics, video, and
audio) on the Web page and describe fill-in-forms. A method is an implementation of an objects
behavior.

7. Explain about HTTP Connection.

It is a communication channel between web browser and web server. It begins on the client side
with the browser sending a request to the web server for a document. Request Header Fields
are
1. From
2. Reference
3. If_modified_since process and the by clicking on the
message log hyperlink in theactions area.
4. Pragma
5. User Agent

8. Define cascading.
Cascading refers to a certain set of rules that browsers use, in cascading order, to determine
how to use the style information. Such a set of rules is useful in the event of conflicting style
information because the rules would give the browser a way to determine which style is
given precedence.
9. State the uses of internet protocol. (APR/MAY 2012)
• IP function: transfer data from source device to destination device
• IP source software creates a packet representing the data
• Header: source and destination IP addresses, length of data, etc.
• Data: Data itself
10. Define Tags. What are the two different types of tags?
Tags signal the browser to inform about the formatting details.ie how the contentshouls be
displayed in the browser screen. Tags are enclosed between “<” and”>”
Standalone tag only start tag is present and no end tag. Example <BR> andcontainer tag have start
and end tag will be present .Example <html>…. </html>
11. What are the rules to define a tag?
Attributes should be placed inside start tag, appears as Name-value pairs separted by
blank spaces, Attributes should have only one value,values should be enclosed within
either single(‘) or double (“) quotes.
12. What is the need of using form in HTML?
Form is a typical layout on the web page by which user can interact with the web page.
The components that can be placed on the form are text box, check box, radio buttons,
and push buttonsand so on. Thus form is typically used to create an interactive Graphical
User Interface.

13. What is the purpose of using frames in HTML?

The HTML frames allows the web designer to present the web document in
multiple views. Using multiple views one can keep the formation visible and at the
same time other views can be scrolled or replaced.
14. What is the need for special character in HTML?
There are some symbols that cannot be used directly in HTML document. For example
<(less than)because this symbol is also used along with the tag. Hence this is called a
special symbol and canbe denoted with the help of entity reference.
15. State how an unrecognized element or attribute treated by the HTML document?
If any unrecocognized element or attribute is written then the HTML document simply
displays the contents. For example <title>testing</title> will display the string “testing”
on the web page. It will not display it as a title of the web page.
16. What is the use of hyperlink tag in HTML?
The hyperlink tag is used to link logically with other page. Using this tag a weblink
can be specified. The <a> tag is used to specify the hyperlink in HTML.
17. What are the uses of hyperlink in HTML?
To logically link one page with another, use of link to enhance readability of theweb
document, the navigation from one page to another is possible.
18. What is BODY in HTML document?
The effects which we want in the window are mentioned with the help of tags inthe body.
It is the place where the actual data is written in html. All the changes can be viewed by
changing the tags content in the body whereas the head part is the introduction part and
the body is the actual content part.<BODY>data content</BODY>
19. What are style sheets?
The style sheets are the collection of styles that can be either embedded within the HTML
documents or can be externally applied. The Cascading style sheet is a markup language
used to apply the styles to HTML elements.
20. What is selector string? Specify any three forms of selectors.
The rule set in CSS consists of selector string which is basically an HTML element. These
selectors can be defined with the help of properties and values.
21. What is the use of Universal Selector?
Using the universal selector the values can be defined for all the elements in the
document. It is denoted by *.
22. What is generic class selector?
The generic class applied to any tag in the HTML document. And thus the values defined
within that generic selector can be applied to the corresponding tag. The class selector
must be preceded by the dot operator.
23. What are the various style sheets?
Inline, external, imported and embedded are the different types of style sheets.
24. Explain inline, embedded andexternal style sheets. Inline
If only a small piece of code has to be styled then inline style sheets can be used.

25. How will you include CSS in a website? (MAY/JUNE

2014) Inline
Inline styles are when you just insert the type of style you want inside another
tag, using the style attribute. This is usually the least useful way to use CSS.
<p style="width:100%; color:#660099; text-align:right; background-color:#ffcc00;" >
External styles
Styles can also be set in an external style sheet which is linked to the page with a
<link> tag. For example the style sheet for this site is included like this:
<link rel="stylesheet" type="text/css" href="class.css" />
26. What is the purpose of CSS Box Model and mention its parts also.
The CSS box model is essentially a box that wraps around HTML elements, and it
consists of: margins,
borders, padding, and the actual content.The different parts are:
Margin,Border, Padding ,Content

UNIT II CLIENT SIDE PROGRAMMING 6

Java Script: An introduction to JavaScript–JavaScript DOM Model-Exception Handling-
ValidationBuilt-in objects- Event Handling- DHTML with JavaScript- JSON introduction – Syntax –
Function Files.
Part – A
1. What is JavaScript?
JavaScript is a platform-independent, event-driven, interpreted client-side scripting language
developed by Netscape Communications Corp. and Sun Microsystems.
2. What are the primitive data types in javascript?
JavaScript supports five primitive data types: number, string, Boolean, undefined, and null. These
types are referred to as primitive typesbecause they are the basic building blocks from which
more complex types can be built. Of the five, only number, string, and Boolean are real data types
in the sense of actually storing data. Undefinedand null are types that arise under special
circumstances.
3. What are the Escape Codes Supported in JavaScript?
The Escape codes supported in javascript are \b Backspace,\t Tab (horizontal),
\n Linefeed (newline),\v Tab (vertical),\f Form feed,\rCarriage return,\" Double quote
\' Single quote,\\ Backslash.
4. What is JavaScript name spacing? How and where is it used?
Using global variables in JavaScript is evil and a bad practice. That being said, namespacing is
used to bundle up all your functionality using a unique name. In JavaScript, a namespace is really
just an object that you’ve attached all further methods, properties and objects. It promotes
modularity and code reuse in the application.
5. How many looping structures can you find in javascript?
If you are a programmer, you know the use of loops. It is used to run a piece of code multiple
times according to some particular condition. Javascript being a popular scripting language
supports the following loops for, while, do-while loop
6. Mention the various Java Script Object Models.
Math Object, String Object, Date Object, Boolean and Number Object, Document Object Window
Object.
7. How Scripting Language Is Differs from HTML?
HTML is used for simple web page design, HTML with FORM is used for both form design and
Reading input values from user, Scripting Language is used for Validating the given input values
weather it is correct or not, if the input value is incorrect, the user can pass an error message to
the user, Using form concept various controls like
Text box, Radio Button, Command Button, Text Area control and List box can be created.
8. What are the different types of objects in JavaScript?
Type Example Implementation Provided Governing Standard
By
User- Programmer defined Programmer None
defined Customer or Circle
Built-in Array, Math The browser via engine its ECMA-262
JavaScript

Document Image, The browser via W3C DOM

HTMLInputElement its DOM engine
9. Justify “JavaScript” is an event-driven programming”
Javascript supports event driven programming. when user clicks the mouse or hit the keys on
the keyboard or if user submits the form then these events and response to them can be
handledusing javascript. Hence javascript is mainly used in web programming for validating the
data provided by the user.
10. What is the use of pop up boxes in java script?
There are three types of popup boxes used in javascript. Using these popup boxes the user can
interact with the web application.
11. What is DOM?
Document Object Model (DOM) is a set of platform independent and language neutral application
interface (API) which describes how to access and manipulate the information stored in XML,
XHTML and javascript documents.
12. Enlist any four mouse events.
The MouseEvent are-mousedown, mouseup, mouseover, mousemove, mouseout.
13. List ad various level of document object modeling. Various levels of DOM are
DOM0, Dom1, Dom2, and Dom3
14. What are they validation properties and methods?
Validation properties and methods are checkvalidity (), validaionMessage, customerror,
patternMismatch, rangeOverflow, rangeUnderflow, tooLong.
15. Define event bubbling.
Suppose, there is an element present inside another element. Then during the event handling, if
the event which is present in the inner element is handled and then the event of the outer element
is handled. This process of event handling is called event bubbling
16. How to create arrays in Javascript?We can declare an array like this Var scripts =
new Array(); We can
add elements to this array like thisscripts[0] = "PHP";
scripts[1] = "ASP"; scripts[2] = "JavaScript";
scripts[3] = "HTML";
Now our array scrips has 4 elements inside it and we can print or access them by using their
index number. Note that index number starts from 0. To get the third element of the array we
have to use the index number 2. Here is the way to get the third element ofan array. document.
write (scripts[2]); We also can create an array like this var no_array = new Array(21, 22, 23, 24,
25);
17. Write a simple program in JavaScript to validate the email-id.

<!DOCTYPE html>
<html>
<head>
<script>
function validateForm() {
var x = document.forms["myForm"]["email"].value;var atpos = x.indexOf("@");
var dotpos = x.lastIndexOf("."); if (atpos<1 || dotpos<atpos+2 ||
dotpos+2>=x.length)
{ alert("Not a valid e-mailaddress");
return false;}}
</script> </head>
<body>
<form name="myForm" action="demo_form.asp"
onsubmit="return validateForm();" method="post"> Email: <input
type="text" name="email">
<input type="submit" value="Submit">
</form>
</body>
</html>
18. Write short notes on JDBC.
JDBC standard is intented for people developing industrial-strength database applications.JDBC
makes java effective for developing enterprise information system.java.sql is the JDBC package
that contains classes & interfaces that enable a java program to interact with a database.
19. Write short notes on JDBC drivers.
A JDBC driver is basically an implementation of the function calls specified in the JDBC API for a
particular vendor’s RDBMS. Hence, a java program with JDBC function calls can access any RDBMS
that has a JDBC driver available. A driver manager is used to keep track of all the installed drivers
on the system. The operations of driver manager are getDriver, registerDriver, deregisterDriver.
20. What are the advantages of servlet over CGI?
Performance is significantly better, servlet execute within the address space
of aweb server.
Servlets are platform independent
The java security manager on the server enforces a set of restrictions to protect
the resources on a server machine.
The full functionality of java class libraries is available to a servlet.
