The Internet and WWW GapFill

The Internet is much older than the  Webelectricity networkgas networkphone network, but the Internet is the underlying network that carries all of our Web traffic, streamed TV and music, online communications such as email and VoIP, etc.

To access the Internet, customers need to contact  their banktheir local post officethe policean internet service provider, who will provide the equipment needed to access the Internet and install the necessary cabling.

You connect to the Internet using a  modemswitchbridgehub and  a switcha bridgea routera firewall (usually in one device) that sends and receives the data packets to and from your home, and creates a small network called a  MANWANLANPAN that all of your devices can share.

The type of network is determined by the technologies available in your area, or the price that you are willing to pay. In an urban area, you might be able to get a fast but expensive  fibreelectricalcopperinsulated connection straight to your house. In rural areas, you might only have access via  fibresatelliteEthernetcopper phone cable.

Another form of Internet access uses the  mobile phonerouteredgesatellite network. This can be through the ‘data’ connection through your mobile phone, or through a separate 4G router that acts as a normal home router but uses a sim card and data receiver instead of using a cable.

The Web was invented by Sir  Steve JobsDavid AttenboroughBill GatesTim Berners-Lee in 1989, while he was working at CERN in Switzerland. He wanted to create an electronic filing system consisting of linked pages of information.

Each web page is written in a language called  PerlPythonHTMLJava. A web  browserfoxserversite (Chrome, Edge, Safari, Firefox, etc.) requests each page from its  URLRSSCSSweb server, and the HTML code instructs the browser on how to display the page on your screen. The modern Web adds extra layers of technology on top – such as extra fonts and styles, and security layers.

Once you have typed the address into the browser, the request to load the page must be sent to the web server that the site is hosted on. But first, the correct web server must be identified. To do this, the address must be converted to the site’s public  browserIP addressserverclient. There are many servers that provide this function around the world. They might be provided by your ISP. They are called  timeDNSwebprint servers.
