4. History and Evolution of Internet
1958 – Pentagon’s Advance Research Project Agency
(ARPA) was established by the U.S. Department of
Defence to make the U.S. leads in scientific and
technological military operations.
1965 – ARPA sponsored a study on a “cooperative
network of time-sharing computers”. Their goal was
to build a network that:
(1) allow scientists at different physical locations to
share information and work together on military and
scientific projects.
(2) that would secure and provide survival to the
information and research from man-made disaster
such as nuclear attack or natural disaster.

5. 1969 – ARPANET was fully functional, linking scientific
and academic researches across United States.
1986 – the National Science Foundation connected its
huge network of five supercomputer center to
ARPANET and the NSFnet was born.
1991 – world wide web introduce to the public by
CERN.
1994 – Yahoo!
1995 – NSFnet terminated its network on the Internet
and resumed its status to research network.

6. 1997 – Netflix
1998 – Google search engine was launched
2004 – Facebook
- Mozilla Firefox Browser
2005 – Youtube.com launches
2006 – Twitter launches
2010 – Social media sites; Pinterest and Instagram
launches.

7. Major Components of the Internet:

8. SERVERS
A SERVER IS A COMPUTER PROGRAM THAT
PROVIDES A SERVICE TO ANOTHER
COMPUTER PROGRAM AND ITS USER.
TYPES OF SERVERS
Application Server - a program in a computer that
provides the business logic for an application
program.
Web Server – a computer program that serves
requested HTML pages or files.

9. cont…
• Proxy Server – is a software that acts as an
intermediary between an endpoint device, such
as computer and another server from which a
user is requesting.
• Mail Server – is an application that receives
incoming e-mail from local users and remote senders
and forward outgoing e-mail for delivery.
• File Server – is a computer responsible for central
storage and management of data files so that other
computer on the same network can access them.
• Policy Server – is a security component of a
policy –based network that provides authorization
services and facilitates tracking and control of files.

10. IP ADDRESS (Internet Protocol)
IS A NUMERICAL LABEL ASSIGEND TO EACH
DEVICE. THIS PROVIDES IDENTITY TO A
NETWORKED DEVICE .
EXAMPLE OF AN IP ADDRESS
72.14.207.99
( an IP Address usually consist of four groups of
numbers. The number in each group is between 0
and 255.)
*the first portion of IP address –NETWORK
**the second portion of IP address – SPECIFIC
DEVICE

11. BROWSER
IS AN APPLICATION PROGRAM THAT
PROVIDES A WAY TO LOOK INFORMATION
ON THE WEB.
EXAMPLES OF BROWSER

12. DNS (Domain Name System)
IS THE PHONEBOOK OF THE INTERNET. WE
ACCESS INFORMATION ONLINE THROUGH
DOMAIN NAMES.
EXAMPLES OF DNS
www.facebook.com
www.teachingenglish.org.uk
www.depedtambayan.ph
www.academia.edu

14. ISP (Internet Service Provider)
•NATIONAL ISP – provided Internet
access to a specific geographic areas.
•REGIONAL ISP – business that
provides Internet access in cities and
towns nationwide.
IS AN ORGANIZATION THAT PROVIDES
SERVICES DOR ACCESSING , USING OR
PARTICIPATING IN THE INTERNET.
TWO TYPES OF ISP’s

15. EXAMPLES OF ISP’s

16. Connecting to the Internet:
• Cable Internet Service – provides high-speed Internet
access through the cable television network via cable
modem.
• DSL (Digital Subscriber Line) – provides high-speed
Internet connection using regular copper telephone wire.
• FTTP (Fiber to the Premises) – uses fiber-optic cable to
provide high-speed Internet access to home and business.
• A Cellular Radio Network – offers high-speed Internet
connection to devices with built-in compatible technology.
• Wi-Fi (Wireless Fidelity) – network uses radio signals to
provide high-speed Internet connections to compatible or
properly equipped wireless computer or device.
• Satellite Internet Service – provides high-speed Internet
connections via satellite dish that communicates with a
satellite modem.

• - working with the European Organization for
Nuclear Research (CERN), developed a basic hypertext
program called ENQUIRE. The program was designed
to make information readily available to users, and to
allow a user to explore relationships between different
pages.
1990 – Robert Cailliau and Berners-Lee developed the
skeletal outline of the internet, including a web browser
and web server.
1993 – Release of the Mosaic web browser
- which allowed users to explore multimedia
online, also this year; introduction of the first modern
search engines.

21. Components of a World Wide Web
 Structural Components:
 Clients/Browsers
 Servers
 Caches
 Internet
 Semantic Components:

 Hyper Text Markup Language (HTML)
 Uniform Resource Identifiers (URLs)

22. Clients/Browsers
Clients are those people who uses the Internet
which also called the end user.
Browser are the application used to access the
internet and surf for information.
Servers
A web servers is a computer that deliver
