 Server  Client Browser  Web Application Architecture  URL (Uniform resource locator)  Hosting  Web Application  Protocols  Ports

 It is a software installed on a computer  Shares resources  Receives requests and generate responses  Run continuously for longer duration with high efficiency, security and reliability  May require special hardware

Web Server  A web server serves static content to a web browser by loading a file from a disk and serving it across the Internet to the user’s browser  During this process the client and server communicate through HTTP protocol  Apache HTTP server (Apache software)  Apache Tomcat (Apache software)  Internet information services IIS (Microsof)  Sun Java (Sun Microsystems)…

FTP (file transfer protocol) Server  It move files securely among computers  Accessed through FTP clients Application Server  It is for runtime processing to prepare response

Server  It sends, receives and stores s over a corporate network across the Internet Proxy Server  Proxy server acts as an intermediary between clients and servers

Database Server  It provides database services to other computers  DNS (Domain Name Server/ System/Service)  Audio/Video Servers  Chat Servers  Game Servers…

 A computer program with GUI to display HTML traverse data from WWW via HTTP

 How web servers and clients communicate with each other

 Buying Domain name  Buying Hosting space

 A set of web pages served from a single web domain  Hosted by a web server  Accessed publicly through a network (Internet)  Has a unique address (URL)  Constitute the WWW  Written in HTML  Accessed through HTTP / HTTPS protocols

 Static Website  Web page delivered in response to client’s request, are in the form in which they are stored. Constructed through HTML, CSS, Javascript, JQuery  Dynamic Website (Web App)  Web pages delivered are constructed at runtime at server, through server-side scripting like PHP, JAVA,.NET  Search Engines  a program that searches for and identifies items in a database that correspond to keywords or characters specified by the user, used especially for finding particular sites on the Internet.

 Content Management Systems (CMS)  Web Portal  Offers a broad array of resources like shopping mall, search engines, ing service, forums etc.
