To learn what are the main technical features of the Internet as a network of computers.


A network is a set of devices which can relate to each other and share resources.


Networks (II)
Internet is a broad, highly-distributed network of physical devices (computers, smartphones, tablets, etc) which can relate to each other in order to share contents and services.

What does
it say

A computer network, or simply a network, is a collection
of computers and other hardware components interconnected
by communication channels that allow sharing of resources and information.

Internet is a network of networks that consists of millions of private, public, academic, business, and government networks, of local to global scope, that are linked by a broad array of electronic, wireless and optical networking technologies.


Networks (III)
To participate in a network some connection (communication) elements are needed: this is the hardware.


Networks (IV)
Some not-physical, logical elements are needed too: software applications which make this communication happen.
These software applications are of different kinds:

Network card drivers.

An Operating system in both connecting devices.

A communication protocol, or language which both connecting devices can speak.


Networks (V)
 Operating systems in the device which connects to the Internet: 

Windows, Linux, MAC OS, Solaris, UNIX, etc.

iOS, Android, Symbian, Windows Phone 7, Blackberry, etc.


Networks (VI)
 Communication protocol.
Although in the beginning of the
Internet different alternatives of
communication protocols where
invented and used, nowadays there
is only one communication protocol
in use: the TCP/IP protocol.


Networks (VII)
 Communication protocol.
This is different with smartphones,
since they can connect to mobile
networks mainly through specific,
phone protocols as 3G or UMTS.
Only when a smartphone connects
to Internet using wifi connection it
uses TCP/IP.


A device is a piece of hardware which does something for us humans. There are lots of devices that can connect to the Internet to improve their funcionalities:






A browser is a software application created specifically to connect to the Internet. The first browser was invented by Tim Berners-Lee at the CERN (a Physics lab in Switzerland) in 1991, as a new way to access and share documents located in the local network. He invented also the concept of link to point to any resource stored and accessible through the network.

As well as the number of machines connected to the same network was increasing, some other people developed Mosaic, a new browser. The evolution of Mosaic arrived to Netscape.
Netscape was the first browser for the common people in the 90s. They were also the company with the biggest growth in the New York Stock Exchange ever. After Netscape other companies soon developed new broswers, like Opera or Internet Explorer.


Browsers (II)
Infography with the commercial browsers history:


Browsers (III)
Today browsers can do almost everything:
 Read web pages.

 Watch videos and TV programmes.
 Listen to music and radio programmes.
 Work with e-mail applications.
 Play games.
 Talk by phone.
 Etc.

Users connect to the Internet to do different things. From a technical point of view, all these tasks can be seen as a request from the user’s device to another device that, if it can and it wants, will answer.

This procedure is common in the Internet and...
