4. Definition of Web Technology
A technology which acts as in interface between web
servers and clients. It includes markup languages,
programming interfaces, standards to define document
identity and display. Basically web technology is the
process which allows two more computing devices over
a network.
some examples of web technologies include:
Mark-up languages including HTML, CSS, XML, CGI
and HTTP;
Programming Languages and Technologies which help
in creating applications for the web; some of the
languages are Perl, C#, Java and Visual Basic .NET;

5. Fetching Pages Over The
Internet
Architecturally, the internet consist of a
collection of layers, each one
providing services for the one above it:
The Internet layer gets packets to their
destinations.
The Transport layer sends streams of data;
The Application layer provides high-level
services to
applications such as Web browsers.
5
7. Hyper Text Transfer
Protocol(HTTP)
HTTP makes use of TCP to open connections
between clients and servers and to pass the
requests and responses between them.
When a user clients a link or types a web address:
1. A TCP connection is opened between browser and
server.
2. Then requests and responses are sent back and
forth using
HTTP.
HTTP is a stateless protocol, meaning each
request for data is dealt with in isolation; once
the server sends the response it forgets
everything about the original request.
7
8. Uniform Resource
Locators(URL’s)
Without a universal addressing mechanism, it
would be impossible to navigate a site, and page
linking would not be feasible
Uniform Resource Locator(URL’s) are used to
identify web pages – basically a URL is a web
address
URLs have 3 components:
A prefix (usually http://)
A Hostname: (such as www.icai.org)
A Path: (such as /new_category.html?c_id=218)
8
10. IP Addresses and DNS
Every computer connected to the
internet must have a unique IP
address, no matter whether it’s a client
or a server (or both)
An IP address is just a number that
identifies a host on the internet.
Example:
116.74.15.1
The Domain Name System(DNS) is a
database that matches IP address to host
10
11. Domain Names
And the Domain Name System(DNS)
translates host names into IP addresses,
which are then used by TCP to establish
connections between HTTP clients and
servers.
Domain names are administered in such a
way that they are guaranteed to be
unique.
Domain names are organized in a
hierarchical structure…..
11
14. Third Level, or Sub Domains
www.google.co.in
Sweb.cityu.edu.hk
www.facebook.com
store.apple.com
Seminars.apple.com
Strings of characters
that designate
different services, or
hosts within the
second level domain.
Example “www” for the
core or main website,
“sweb” for SCM’s sub
-network within cityU
14
15. Linking Domain Name and IP
Addresses
A domain name, once registered, needs to be
associated with a fixed IP address of a web
server on the internet.
When you register and setup a new domain name,
you need to enter details of at least 2 name
servers.
These name servers are special internet servers that
implement a name service protocol
They may be provided by a web hosting service, or a
domain registration service.
They link a domain name to the specific IP address
assigned for a website
15
16. Domain Names… not just
websites
Once your domain name is assigned a
specific IP host you can:
Set up and run a
website(www.icai.org)
Set up e-mail accounts(info@icai.org)
Set up file transfer
capabilities(ftp.icai.org)
16
17. Home Page Naming
For –
http://www.icai.org
…there must be a default HTML page
that is displaying as the home page. In
the case of ICAI, it is…
http://www.icai.org/index.html
…meaning index.html is the default
HTML page in the root directory of the
server.
17
18. Server Software
Just connecting a computer to the internet
and giving it an IP address does not
make it a web server. Server computers
have to run special web server software
to open TCP connections and respond to
HTTP requests.
The two most common web server
applications are:
apache (UNIX-based, open source) 50%*
IIS – internet information services(Microsoft)
36%*
* Percent of all websites served on the internet: Sept.

19. Summary
Uniform Resource locator(URL)
The common addressing mechanism used to navigate the web
http://www.icaionlineregistration.org/index.html
prefix host name,
the transfer protocol at the domain name
Applications layer; hypertext
Transfer protocol(HTTP) is
Used to request web pages
And related data from a server
identifies a particular computer
or server somewhere on the
internet.
The Domain Name System
translate Internet Protocol(IP)
Addresses into unique
Recognizable names that have to
Be registered with assigned
Domain registration services.
Second- or sub level domains
Can identify different servers or
Services within the same domain.
Path, pathname
Identifies a file within a
Hierarchical directory structure
On the server.
Paths can be Absolute(that is,
Hierarchical from the top of the
File system or volume), or
Relative(that is, hierarchical
from the top of a designated
Working directory/ root
Directory.
Relative paths are much
Preferred for creating and
Managing groups of web pages
And resources within a site.

20. Social Network
Social networking is the use of internet-based
social media programs to make connections with
friends, family, classmates, customers and
clients. Social networking can be done for social
purposes, business purposes or both. The
programs show the associations between
individuals and facilitate the acquisition of new
contacts. Examples of social networking have
included Facebook, LinkedIn, Classmates.com
and Yelp.
