The internet & the jargon you're going to need to understand it.By Joe Homer
Slide 2
When was the internet first developed?
The internet all started when in 1967 a concept was published which then gave the U.S. Advanced Research Projects Agency (ARPA) the idea of the internet. They created a network called ARPANET which was a basis for the internet and then in 1969 they tried it out to become a success when they connected 4 university computers. It took a big leap when on January 1st 1983 ARPANET adopted TIP/IP and researchers created the "network of networks" that came the modern internet, skip forward 7 years when a man called Tim Berners-Lee made the more recognisable world wide web.
Commonly used features on a web browser:
Navigation buttons (forward and back arrows)
Refresh Button
Stop Button
Home Button
Address bar and web search
Bookmarks and tabbed browsing
History Tab
Web browsers functions are to give the user information when asked for it, in the form of a URL which processes the user information like "http://www.google.com". This allows access to the webpage.
A search bar is essentially a text box that you type key words into and the search bar checks these across what its got on its website and give you the best results to the words you typed in.It does this by going through 3 basic stages;
Crawling - where content is discovered
Indexing - where its analysed and put in a database
Retrieval - which is when a user query fetches a list of relevant pages.

What is a Web Server & How Does it Work
A web server is a computer system that processes requests via HTTP (hyper text transfer protocol) link. This is the basic network protocol used to send things onto the world wide web (WWW). This can refer to the entire system or just specifically to the software that allows and denies HTTP requests. Web servers are used to give users webpages in response to their request.
Slide 6
Domain Name and URL
A domain name is a host name that makes it easier to remember a website instead of using an IP address. So instead of using a list of numbers, you can easily remember ounsdale.com or netflix.com, where as a URL is the actual code searched for example http://www.ounsdale.co.uk or https://www.netflix.com/browse.
