1. The Internet and the World
Wide Web [WWW]
By: Owolabi Emmanuel

2. INTERNET
The internet is a global network of computers that use
protocols and data packets to exchange information.
INTERconnected NETwork
● The first workable prototype of the
Internet was the ARPANET (Advanced
Research Project Agency Network) in the
late 1960s. After its adoption on January
1st 1983, researchers began to develop a
“network of networks” which evolved into
the modern form of the Internet

3. WORLD WIDE WEB
The World Wide Web (WWW or 'web' for short) is the part of the
internet that you can access using a web browser.
● The invention of the World Wide Web can be
credited to Sir Tim Berners Lee. During his
work at the European Organization for
Nuclear Research in 1989, he had developed
the basic idea of the WWW to merge the
evolving technologies of computers, data
networks and hypertext into a powerful and
easy to use global information system.

web.

5. The differences between the internet and the World wide web.
INTERNET WORLD WIDE WEB
The internet is a public network of network with a
maze of wired and wireless connections between
separate groups of servers computers and
countless devices from around the world.
The World Wide Web is the common system for
navigating the internet. It is not the only system that
can be used for such access, but it is by far the most
common one.
Along with Internters, there also exist the Intranets,
which is the same type of information network but
more privatized in order to control access.
The World Wide Web is distinguished from other
systems through its use of HTTP (Hypertext Transfer
Protocol).
Internet is primarily hardware-based. WWW is more software-oriented as compared to the
Internet.
The internet is governed by a set of rules and
regulations collectively known as Internet Protocol
(IP). The IP deals with data transmitted through the
internet
The HTTP along with being the language of the World
Wide Web also governs it by dealing with linking of
files, documents and other resources

6. Uniform Resource Locators
A uniform resource locator (URL) is the address that is used in the web
browser to request a resource (web page) from the world wide web.
It is usually written in a format which contains three main parts.
protocol://website address/file name
The protocol is
usually either
http or https.
The website address is:
➔ Domain host (www)
➔ Domain name (website name)
➔ Domain type (.com, .org, .net)
➔ and sometimes county code (.ng,
.uk, .de, .cy).
The file name is
the item on the
web page.

9. Hypertext transfer protocol
Hypertext transfer protocol(http) is a set of rules that must be followed when
transferring files across the internet. When some form of security (for example, SSL
or TLS) is used, then this changes to https.

10. Web browsers
A web browser is a software program which allows the user to request and retrieve
web pages (and other resources) from a webserver on the world wide web.
Web browsers interpret convert the HTML code from the retrieved webpage and
display it to the user in a format they can understand.

13. Features of Web Browsers

14. Retrieval and Location of Web Pages
A web page (or webpage) is a hypertext
document on the World Wide Web. Web
pages are delivered by a web server to the
user and displayed in a web browser.
