7. History:
Year Achievements
1980 Tim Berners-Lee invents the WWW, at CERN (the world famous nuclear
research lab at Switzerland).
1990 Concepts like - HTTP, Web browser, Uniform Resource Identifier (URI) and
HTML
1993 Launch of the first graphical web browser, named - MOSAIC at USA.
1994 Hosting of the first International WWW Conference, formation of World Wide
Web Consortium (W3C)

8. World Wide Web (WWW):
 Tim Berners-Lee has developed WWW, HTML, URLs,
and HTTP.
 In 1980: Tim Berners-Lee invents the WWW, at CERN
(the world famous nuclear research lab at Switzerland).
 In 1989: Tim Berners-Lee invents the Web with HTML
as its publishing language.
 In June 1994, the IETF published Berners-Lee's RFC-
1630, the first Request for Comments that
acknowledged the existence of URLs and URNs. Most
importantly, it defined a formal syntax for Universal
Resource Identifiers (URI).
 Vint Cerf is considered to be one of the fathers of the
Internet, having been the co-inventor of TCP/IP.

9. Web Browser:
 A web browser is a software application for retrieving, presenting, and traversing
information resources on the World Wide Web.
 The primary purpose of a web browser is to bring information resources to the user.
 The major web browsers are Windows Internet Explorer, Mozilla Firefox, Apple Safari,
Google Chrome and Opera.

10. Web Server:
 The term web server or webserver can mean one of two things:
 A computer program that accepts HTTP requests and return HTTP responses with
optional data content.
 A computer that runs a computer program as described above.

11. Web Server vs Application Server:
Web Server Application Server
Deliver static content. Delivers dynamic content.
Content is delivered using the HTTP protocol only. Provides business logic to application programs
using several protocols (including HTTP).
Serves only web-based applications. Can serve web and enterprise-based applications.
No support for multi-threading. Uses multi-threading to support multiple requests
in parallel.
Facilitates web traffic that is not very resource
intensive.
Facilitates longer running processes that are very
resource-intensive​.

12. URI:

13. HTTP:
 HTTP is an application-level protocol for distributed, collaborative, hypermedia
information systems.
 HTTP is a request/response standard of a client and a server.
 Typically, an HTTP client initiates a request.
 Resources to be accessed by HTTP are identified using Uniform Resource
Identifiers (URIs).
 Port Id is 80.
