Internet and WWW (What is the Internet? (But the Internet isn't just…
Internet and WWW
The Internet is made up of millions upon millions of small computer networks all brought together to form the vast "Inter-Network". That word never caught on, so it was shortened to the much easier-to-say "Internet".
-
This is made up of websites that have one or more web pages. This is part of the Internet that you probably use most of the time.
-
Note that no-one 'owns' Internet. This is because each part of it is made up of individual networks that someone put together and then linked to the Internet .
However, each network has to obey Internet standards in order to connect. For example IANA is an international group responsible for organising web addresses - every web address has to be unique.
-
The Internet is to the World Wide Web as Europe is to France. One is the container, the other is an item within the container.
The world wide web (WWW or just 'the web' ) is part of the Internet but is much younger. The Internet is merely 40 years old whilst WWW is merely 25 years old
It was developed at CERN, the world famous underground physics laboratory in Switzerland, by Tim-Berners Lee around 1990.
The complete web is organised as millions of ' web sites'. Each web site is made up of one or more ' web pages '. Each page is made up of text, images or multomedia such as video and sound.

- Web sites, pages and browsers
Web sites are hosted on dedicated computers known as 'web servers'. These machine will send a web page to your browser when you request it.
There are many different browsers available, such as Chrome, Firefox, Internet Explorer, Opera, Safari and so on. bUt they all do the same job - namely to display a web page delivered from a web server.

This is very important, as it is what binds the World Wide Web together. The http is a 'protocol', which is a fancy word for a communication standard. If two computers share the sam 'protocol', then they can share information. The http protocol is the one used for the world wide web.
The internet is more than just World Wide Web, and those other parts use different protocols. For example for exchanging files between internet computers us the 'ftp' protocol.

Information overload
There is almost too much information on the Internet. It is easy to feel overwhelmed by the amount of information that is out of there.
When you type a search term into a search engine, you won't just get few minutes results, you will get millions.
Search engines do a good job at prioritising which are the most relevant sites for your search term. However However that one piece of information that you are after might be on page 345 of the results. There is very little chance that you are going to find it.

It began life about 40 years ago, in America military research agency called DARPA. Its invention could never have forseen how it would develop over time
The Internet now spans the world, connecting billions of people in their everyday lives.

The Internet is always available for you to use, 24 hours a day, 7 days a week, 365 days a year. You don't have to wait for it to open or wait for someone to make it available. It is just here, when you need it and for whatever you need.

Up to date
One of the main advantages of the Internet is how fast things can be updated. When new story breaks, the BBC website can have that new on its page within a couple of minutes. They can keep adding more information as it becomes available.
If that were a newspaper, you would have to wait up to to a day to read about the news. Even news on the television takes longer to get to you then the Internet.
