1.9 WEB ARCHITECTURE
Web architecture can be defined as the internet’s conceptual framework. The World Wide Web, or the internet, is a
dynamic medium that allows users to communicate with one another as well as technical interaction between different
systems and subsystems. Data transmission protocols (TCP/IP, HTTP, HTTPS), representation formats (HTML, CSS, XML),
and addressing standards are the three main components of the internet’s infrastructure (URI, URL). Some of the main
components that make up Web Architecture are as follows:
Ð ÐClient: The client is the web browser or application a user employs to interact with a server. It sends requests
for content and receives responses to display to the user. This process enables users to access online resources
seamlessly.
Ð ÐServer: A server hosts websites and web applications, processing requests from clients. It retrieves data and delivers
the appropriate responses. Servers can manage multiple sites simultaneously, optimizing resource usage.
ÐNetwork: The network connects clients and servers, facilitating communication between them. It comprises
Ð
routers, switches, and cables that transmit data packets. Network efficiency significantly affects the performance
of web applications.
Ð ÐDatabase: The database stores and organises data for websites and applications. It manages various types of
information and provides it upon server requests. Modern databases can efficiently handle large volumes of data
and complex queries.
Ð ÐWebsite or Web Application Structure: The website or web application structure encompasses how the site is
organized and arranged, including its layout and navigation. This structure affects user experience by guiding users
through the content. A well-designed structure enhances accessibility and engagement, making it easier for users
to find information.
Origin
The World Wide Web (WWW) is a concept that was developed in the 1990s to allow people and machines to
communicate within a defined area. It is used to exchange, transmit, and share data in a network. Let us understand
its journey from the following figure as given below:
Web 1.0 Web 2.0 Web 3.0
Static web pages Dynamic webpages Extremely Mobile
Nil communities Social Media Microblogging
Rich user experience Advanced search
Types of Web Architecture
There are mainly four types of web architectures which as follows:
Web Architecture
Peer-To-Peer Client-Server Three Tier Service-Oriented
Networking Model Model Architecture (SOA)
