Answer the following questions
1. What is Internet?
Ans :
The Internet is a global system of interconnected computer networks that use the standard Internet Protocol Suite (TCP/IP) to serve billions of users worldwide. It is a network of networks that consists of millions of private, public academic, business, and government networks.
2. Define Internet protocol.
Ans :
The Internet Protocol (IP) is a
protocol, or set of rules, for routing and addressing packets of data so that
they can travel across networks and arrive at the correct destination. Data
traversing the Internet is divided into smaller pieces, called packets. IP
information is attached to each packet, and this information helps routers to
send packets to the right place. Every device or domain that connects to the
Internet is assigned an IP address, and as packets are directed to the IP
address attached to them, data arrives where it is needed
3. What is WWW?
Ans :
The World Wide Web, abbreviated as WWW
and commonly known as the Web,
is a system of interlinked hypertext
documents accessed via the Internet. With a web
browser, one can view web pages that
may contain text, images, videos, and other
multimedia and navigate between them
via hyperlinks.
4. Write the format of HTTP request
message
Ans :
An HTTP request message consists of a
start
line followed by a message header and
optionally a message body. The start line always
consists of printable ASCII characters,
and the header normally does as well. What’s more,
the HTTP response (or at least most of
it) is often also a stream of printable characters.
5. Write the format of HTTP response
message.
Ans :
an HTTP response message consists of a
status line, header fields,
and the body of the response, in the
following format:
Status line
Header field(s) (one or more)
Blank line
Message body (optional)
6. Define web client.
Ans :
A web client is software that accesses
a web server by sending an HTTP request message and processing the
resulting HTTP response. Web browsers running on desktop or
laptop computers are the most common form of web client software, but
there are many other forms of client software, including text-only
browsers, browsers running on cell phones, and browsers that speak a page
(over the phone, for example) rather than displaying the page.
7. Define web server in computer
networking.
Ans :
To view and browse pages on the Web,
all you need is a web browser. To publish pages on the Web, you need a web
server. A web server is the program that runs on a computer and is
responsible for replying to web browser requests for files. You need a web
server to publish documents on the Web. When you use a browser to request a
page on a website, that browser makes a web connection to a server using
the HTTP protocol.
The browser then formats the
information it got from the server. Server accepts the connection, sends
the contents of the requested files and then closes.
8. What is FTP?
Ans :
FTP (File Transfer Protocol) is a
network protocol for transmitting files between computers over Transmission
Control Protocol/Internet Protocol (TCP/IP) connections. Within the TCP/IP
suite, FTP is considered an application layer protocol.
9. What is HTTP?
Ans :
The primary TCP-based protocol used for
communication between web servers and browsers is called the Hypertext
Transport Protocol (HTTP)
10. Explain the characteristics of
effective web design.
11. Write a short note on Page Layout
and Linking.
12. Define website planning. Explain
the steps for Planning publishing a website
Ans :
Planning for designing web pages:
Breaking Up Your Content into Main
Topics
With your goals in mind, try to
organize your content into main topics or sections, chunking related
information together under a single topic.
Ideas for Organization and Navigation
At this point, you should have a good
idea of what you want to talk about as well as a list of topics. The next
step is to actually start structuring the information you have into a
set of web pages. Before you do that, however, consider some standard
structures that have been used in other help systems and online tools.
This section describes some of these structures, their various features, some
important considerations, including the following
Model and Structure of a Web site:
You need to know what the following
terms mean and how they apply to the body of work you're developing for
the Web:
Website: A collection of one or more
web pages linked together in a meaningful way that, as a whole, describes
a body of information or creates an overall effect.
Web server: A computer on the Internet
or an intranet that delivers Web pages and other files in response to
browser requests.
Web page: A single document on a website,
usually consisting of an HTML document and any items that are displayed
within that document such as inline images.
Home page: The entry page for a
website, which can link to additional pages on the same website or pages
on other sites.
Developing websites: Designing a
website, like designing a book outline, a building plan, or a painting,
can sometimes be a complex and involved process. Having a plan before you
begin can help you keep the details straight and help you develop the finished
product with fewer false starts. Today, you learned how to put together a
simple plan and structure for creating a
set of web pages, including the
following:
• Deciding what sort of content to
present
• Coming up with a set of goals for
that content
• Deciding on a set of topics
• Organizing and storyboarding the
website
13. Explain HTML.
Ans : HTML stands for Hypertext Markup
Language. The idea here is that most documents have common elements for
example, titles, paragraphs, and lists. Before you start writing,
therefore, you can identify and define the set of elements in that
document and give them appropriate names.
14. Explain following tags with
attributes:
<frame>
Ans :
After you have your basic frameset laid
out, you need to associate an HTML document
with each frame by using the
<frame> tag, which takes the following form:
<frame src="document
URL">
For each frame defined in the
<frameset> tag, you must include a corresponding <frame>
tag, as shown in the following:
Input
<html>
<head>
<title>The FRAME
Tag</title>
</head>
<frameset rows="*,*,*">
<frame
src="document1.html" />
<frame
src="document2.html" />
<frame
src="document3.html" />
</frameset>
</html>
<form>
Ans :
To accept input from a user, you must
wrap all of your input fields inside a <form> tag.
The purpose of the <form> tag is
to indicate where and how the user's input should be
sent. First, let's look at how the
<form> tag affects page layout. Forms are block-level
elements.
Input
<p>Please enter your username
<form><input /> and password <input /></form> to log
in.</p>
The two most commonly used attributes
of the <form> tag are action and method. Both of
these attributes are optional. The
following example shows how the <form> tag is
typically used:
<form action="someaction"
method="get or post">
content, form controls, and other HTML
elements
</form>
action specifies the URL to which the
form is submitted. Again, remember that for the
form to be submitted successfully, the
script must be in the exact location you specify and
must work properly.
<table>
Ans :
The to create a table in HTML, you use
<table>...</table> element to enclose the code
for an optional caption, and then add
the contents of the table itself:
<table>
...table caption (optional) and
contents...
</table>
Rows and Cells
The cells within each row are created
using one of two elements:
• <th>...</th> elements are
used for heading cells. Generally, browsers center the contents
of a <th> cell and render any
text in the cell in boldface.
• <td>...</td> elements are
used for data cells. TD stands for table data.
<anchor>
To create a link in an HTML page, you
use the HTML link tag <a>...</a>. The <a> tag
often is called an anchor tag because
it also can be used to create anchors for links.
Input
Go back to <a
href="menu.html">
Main Menu</a>
15. What are Cascading Style Sheets?
Ans :
Style can be delivered to a document by
a variety of methods. The method with which style is connected with a
document is referred to as integration . There are a variety of ways to
integrate style, and how you decide to integrate style will depend largely
upon what you are trying to accomplish with a specific document or number
of documents.
16. What is External Style Sheet? How
to link"
Ans :
External Style Sheets:
An external style sheet contains as
many style rules as you like and helps to provide a most powerful means
for you to create master styles that you can apply to one page or one
billion pages.
An external style sheet is exactly
that—all of the style is placed in an external file. You can link to the
style sheet from any document you wish, using the link element in the
head portion of those documents with which you’d like to integrate the
style.
The external style document is a text
document that you can write in any editor or tool that allows you to save
a document as text. To create a linked style sheet, follow these
steps:
1. Open your text or HTML editor of
choice.
2. Enter the style rule or rules you’d
like.
h1 {
font: Arial;
}
3. Select File, Save and save your file
with the name of h1style and a .css extension
(style.css).
16. What are the selectors in CSS?
17. Design a CSS which sets the space
between lines.
18. Demonstrates how to use the
shorthand property for setting all of the font properties one declaration.
19. Demonstrates all the different

34. Write a JavaScript to display first
10 Fibonacci numbers.
Ans :
var fibonacci_series = function
(n)
{
if (n===1)
{
return [0, 1];
}
else
{
var s =
fibonacci_series(n - 1);
s.push(s[s.length - 1] +
s[s.length - 2]);
return s;
}
};
console.log(fibonacci_series(10));
35. Design a login page. If the user id
and password is correct then display appropriate message.
36. Create a web page, which accept
user information on the web site. Design the web page using form element and
