3. URL
URL means a Uniform Resource Locator. It is a
term used in the web world or other internet
sources, which has two different meanings to it.
One, it is popularly known as the Uniform
Resource Identifier (URI).Technically people
refer to it as URL instead of URI. Second, it is a
subset of URI to identifiers who are primary
locators. It is also pronounced as an acronym
"EARL". It is an internet address that consists of
http (access protocol), the domain name and it
could also include the path to a file or resource on
the server.
A Uniform Resource Locator helps detect a
location with the help of itsnetwork location.
URL normalization is a method by which URL
are normalized in a reliable manner. This process
transforms the URL into a normalized. With this
process we can determine if different URL's are
equivalent.

4. Understanding a URL
A URL (Uniform Resource Locator)is a unique address
for a web site.
.com
Commercial sites that are in the business of selling
something to the visitor. (www.amazon.com)
.net
Commercial sites that are in the business of selling

~
Personal sites that are unedited and opinionated
(www.gradmath.fresno.edu/~xfiles)
members.aol
users
.geocities
Same as above (www.softcom.net/users/rossd22)
.gov
These are tax dollar supported sites. They tend to be fairly
objective and free from an overt ideologic stance. They host
current acts, policies, and historical records.
.edu
College or university hosted sites offer research results and
repositories of information.
.org
Organizations (nonprofit) that may or may not be perfectly
objective.
5. WebSite
1. A website (also written Web site or simply site is
a collection of related web pages containing images,
videos or other digital assets. 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 also called URL.
6. Web Page
A web page or webpage is a document or information resource that is
suitable for the World Wide Web and can be accessed through a
web browser and displayed on a monitor or mobile device.This
information is usually in HTML orXHTML format, and may provide
navigation to other web pages via hypertext links
Type of Web Page -
1. Static web Page
2. Dynamic Web Page
.
7. Static Web Page
Static Web pages
A static Web page contains content that displays the same way
each time the page is requested from a browser. An example of
a static Web page is a help page that contains contact
information (such as return policy or "brick and mortar" store
locations) that does not change frequently.
A static store page is created using only HTML. Static store
pages can contain HTML tags and text, as well as other
elements suitable for the page, such as images and animation,
but they do not make use of the information in the database
8. Dynamic web page
Dynamic Web pages
A dynamic Web page contains content that is generated when the user
requests the page. This content is typically extracted from a database,
allowing the store to present the most current information.
An online store typically has many more dynamically generated pages
than static pages because most of the store's information changes
frequently. For example, products change, prices change, and customer
information changes on a relatively frequent basis. A dynamic Web
page acts as a template; it contains code to retrieve required information
and format the output.
Typically, you create dynamic Web pages for product and category
pages, the shopping cart page, the registration form, and the order forms.
You can create dynamic Web pages in WebSphere Commerce using
JavaServer Pages technology.
9. WWW
The term WWW refers to the World Wide Web or simply the Web.
The World Wide Web consists of all the public Web sites connected to
the Internet worldwide, including the client devices (such as computers
and cell phones) that access Web content. The WWW is just one of
many applications of the Internet and computer networks.The World
Web is based on these technologies:
HTML - Hypertext Markup Language
HTTP - Hypertext Transfer Protocol
Web servers and Web browsers
10. Web Browser(Client)
A Web browser is a software program that interprets the coding
language of the World Wide Web in graphic form, displaying the
translation rather than the coding. This allows anyone to “browse the
Web” by simple point and click navigation, bypassing the need to know
commands used in software languages.
The World Wide Web is written in Hypertext Markup Language
(HTML). Viewed with software other than a Web browser, HTML looks
nothing like its graphic translation. To take a peek, right-click on any
empty space in a webpage. A small pop-up menu will appear.
Choose View Page Source in FireFox, or View Source in Microsoft’s
Internet Explorer (IE). When finished viewing the HTML coding, click
the window closed to return to the Web browser window.
11. Web Server
A web server program is software that runs
on the web site hosting Server computer. Its
main purpose is to serve web pages; which
means it waits for requests from web
browsers (also known as clients) and
responds by sending the required data back.
12. Web Application Programming
Web based application are developed using
Client Side Programming -
Software that download from web Server to browser and
then executed on the Client.
They are created using languages HTML ,DHTML
(Dynamic HTML) , VBScript , JavaScript.
Server Side Programming –
Software that run on the server not the client .
Languages used – ASP , JSP (JAVA EE ) , PHP , ASP.Net
