For example , we can be on our team in Barcelona and
connect to another computer physically located in New York. Once the Internet
connection , you can download a song or a movie of that team in New York and
vice versa. All this in record time , always depending on the file size and
connection type . Internet is a vast network of interconnected computers and
allowing the exchange of any type at any time , and when you are thousands of
miles away .
The Internet was created in 1968 by the U.S. Army as
a safe non of touch and isolated disaster (nuclear attack or other) . What I
never imagined was that evolve into a worldwide network of computers and
extended robust public use , allowing people to communicate immediately.
Although this is a borderless network owners or defined , is run by big
business called Internet service providers (ISP ), which are the ones that give
the Internet service required .
For sharing files and information in a large network
such as the Internet , the standard method used is the WWW (World Wide Web or
Internet . ) The web is a system of servers located around the world, transfer
documents called web pages. The website uses so-called browsers or browsers to
access these sites . The most popular browsers are Internet Explorer , Netscape
and Mozilla Firefox (the latter highly recommended) .
The web pages are formatted with HTML , which is a
programming language that supports image files , audio and video. Another
feature is that it supports HTML links to other sites , both internal to other
websites. This allows you to go from one place to another in a matter of
seconds by clicking on a link or "link" .
This file transfer , WWW uses a protocol called HTTP
( hypertext transfer protocol ) , who always sees the start of our browser
address bar .
Basically , WWW is a way to access information on
the Internet , while the infrastructure of the Internet is a massive network of
computers.
Given the reach of the Internet to do searches on
specific topics without getting lost in the millions and millions of Web pages,
Internet search engines that rank in the organization of this great world
united together are used.
Now I know ... I need for my Internet access?
Before you can connect to the Internet , you need
some equipment to help you with information and links . In an overview need a
modem (for low speed) or a router (high speed) , a phone line ( if you're home
) or a LAN connection ( for business and do not need a modem) , and one count
of ISP as mentioned above, to access the Internet .
Hardware
Requirements
If you want to access the Internet from home need a
modem to connect to your ISP, in turn will launch the Internet . The modem
speed is an important consideration when you want to download or upload files
on the Internet. A modem will give a maximum speed of 56 Kbps
For maximum speed you can choose an ADSL connection
, which will allow us greater bandwidth and speed of navigation and transfer of
large files . To do this, the company ( ISP) with which we hired our Internet
connection will provide an ADSL router and need to access the web software.
In both cases , we will need a phone line that will
serve as a starting point to the network. A point to consider is that while
connected to a modem, you will not have the ability to receive or make phone
calls. Unlike ADSL connection, you can browse and use your phone at the same
time, which is a big plus . Needless to say it is more expensive than ADSL
modem Internet .
It is possible that the router is the wifi or
wireless connection. Therefore, if we have one or more laptops at home ( or
office) , we can move through the environment without losing your Internet
connection .
The points that should be evaluated when hiring a
service provider (ISP )
Unfortunately, in some parts of Europe and
especially in Spain , holiday Internet is still a bit expensive compared to the
leaders in this technology. Still, the secret is to compare the information
from friends , forums or other means and make the right decision.
We do price comparison and switching times . Today,
it is normal to ask for a flat fee of a definite time or contract of 24 hours.
We should study the offers that are released and choose the most interesting
You should evaluate the service and support they
offer. We are not good to have the best economic and bandwidth if we will then
have problems from time to time. Do not make us lose time and patience.
As each country has its own rules for choosing ISP ,
this step will be a very unique choice.
