The document discusses key concepts in web technology including markup languages like HTML and CSS, scripting languages like JavaScript and VBScript, and how they are used to create dynamic and interactive web pages. It also provides an outline of two course modules that will introduce students to these concepts and languages and how to use them to add functionality and validate forms. Additionally, it summarizes the history and development of the internet and world wide web, defines common web terms like URLs, HTTP, websites, web browsers, and email.

4. Web Technology is Set of technologies
used to create web application and
make the web pages interactive, and
more powerful.

5. Markup Language :
HTML
Style Sheet Language :
CSS
Scripting Language :
VBScript, JavaScript
A markup language is a computer language that uses tags to define elements within a
document.
Scripting languages, which can be embedded within HTML, commonly are used to add
functionality to a Web page, such as different menu styles or graphic
Cascading Style Sheets is a style sheet language used for
describing the presentation of a document written in a markup
language like HTML

7.  Web history
 www
 internet, URL , HTTP

8. Tim Berners-Lee invented the World
Wide Web in 1989.
the WWW project was initiated at
CERN (European Center for Nuclear
Research) to create a system to handle
distributed resources for scientific
research.

9. WWW :World WideWeb or web
WWW is a framework for accessing linked
documents spread out over millions of machines
all over the Internet. The WWW has a unique
combination of flexibility, portability, and user-
friendly features.

10.  WWW works on
client- server
approach

11. The Internet is the global system of
interconnected computer networks that uses
the standard Internet protocol (TCP/IP) to
communicate between networks and devices.

12.  Developed in 60s and 70s by US Department of Defense
 called ARPANET
 90s: network : known as Internet.
 Internet and Web is not the same thing: Web uses internet to
pass over the information.

13. The diagram, developed by the Malone Media Group, outlines the History of the Internet.

14.  A standard way of specifying the location of a web page, on the
Internet
 It defines four things: method, host computer, port and path.
 Method – protocol used to retrieve the document like HTTP.
 Host– a computer where the information is located.
 Port– optional port # of the server (default is 80)
 Path– the path name of the file where the information is located
Method: // Host computer : Port / Path
eg: https://www.gla.ac.in/academics/department-of-computer-
engineering-application

15.  HyperText Transfer Protocol is The protocol used to transfer
Web pages through the Internet.
 HTTP is a “stateless” protocol which means that the
connection between the browser and the server is lost once the
transaction ends.
A protocol is a standard set of rules that allow electronic
devices to communicate with each other.

16. Web page
Website,Web portal,Web Development
Web Browser
Email

17. The WWW consists of a vast,
worldwide collection of documents.
These documents are known as Web
Pages, often just called pages for
short. The web pages are created by
using different markup languages.

18.  Static web page are fixed content documents that are created
and stored in a server. The contents in the server can be
changed, but the user cannot change it.
 Dynamic web page shows different information at different
point of time a fresh document is created for each request, the
contents of a dynamic document can vary from one request to
another.

19.  A website is a collection of web pages and related content that
is identified by a common domain name and published on at
least one web server. Notable examples are
 Example: gla.ac.in, wikipedia.org, google.com, and
amazon.com.

20.  a website is a location on the internet that is unique and which
is accessed via a web browser using a specific URL (web
address). Portals are also accessed via a web browser and
specific URL, but content is login protected and user-specific.
 Example:
 gla.ac.in is a website while
 glauniversity.in:8085 is web portal

21.  Web development refers to building website and deploying it
on the web. Web development requires use of scripting
languages both at the server end as well as at client end.
Client Side coding:
Ajax,Javascript,
Vbscript,
HTML, CSS ,..
Server Side coding:
ASP, CGI
Javascript,PHP
Python
Java, .NET ,..
Web development

22. Pages are viewed with a program
called a browser, of which Internet
Explorer and google chrome are two
popular ones. The browser fetches
the page requested, interprets the
text and formatting commands on it,
and displays the page properly
formatted on the screen.

23. Electronic mail (email or e-mail) is a method
of exchanging messages ("mail") between people
using electronic devices
Each user of email is assigned a unique
name(E-mail address) for his email account.

24. Email message components:
E-mail Header: From, Date, To, Subject, CC, BCC
E-mail Body: Greeting , Text and Signature
