Transcript of The internet and its components.
What does each part do?
How does it work?
The internet works by following a route which goes like this:-
The web client requests a package.
It then sends that request to the DNS.
The DNS then sends it to the ISP.
The ISP finds where the page that the request asks for is stored and gets the IP address.
After that the ISP gives it to the DNS.
The DNS then gives it to the Router.
The router then sends its request for that page to the ISP .
The ISP then sends it to the server it is being held on.
Then the server sends a copy of the page to the ISP .
The ISP then sends it to the router .
The router then sends it to the web client.
Finally you are able to view it.
All this happens in sometimes less then a whole second.
What is the internet?
The internet is all the networks in the world that are connected. Unlike the world wide web it is the hardware side of it, whereas the world wide web is the software side.

The router is what sends the request for the IP of a web page to the ISP as well as receive it.
Website servers hold copies of each website and then make copies of them to send out whenever they are requested for by an ISP.
Similar to website servers they hold copies of your Emails so that when you log on your email client automatically sends a request for them.
Proxy servers have many uses however not all of them are legal. Their legal use is to pretend to be your own computer for security.
Web browsers are there to allow you to search for a website as well as display it. It also has many short cuts to make getting to different websites much faster. When you make a search request that request is then sent to the router, when the router gets that page's IP address it then sends it to the web browser which in turn displays the page for the user to see.
When you load up any email software E.G. Google mail. The email software will automatically ask the router to go and collect that accounts Emails. Also when you send an Email the Email software will ask the router to send it to the Email server for storage.
Your ISP is the middle man in terms of getting things from the internet or getting into the world wide web. They will take your request from either your DNS or router and then go and find them as they know where each file is stored. E.G. If you search "google" your DNS will ask your ISP to get its IP address, your ISP will then go to the server where "google" is stored and get its IP address then give it back to your DNS.
Website hosting services are so that when you have a website you can pay a ( usually monthly) fee for them to hold and show your website on their servers. The advantages of this are that you don't have to get your own servers to host it meaning in the short term it will be much cheaper however in the long term it may become cheaper to just buy your own servers, but it is depends on the business.
Marketing on the internet is very popular as it can show all the stock you can possibly have however at a fraction of the cost of having to ship them to all of the stores and owning a store as well. They are also very easy and quick to update.
Similar to marketing it shows all of your products that are available in an almost infinite space. It also means you don't have to pay for a shop and that more people can see your catalog without them needing to travel to their nearest store. It is also a much cheaper and effective way rather than using a paper catalog.
Intranets allow there to be limited access to a WAN which means that it is a good location to put files that you need co-workers or employees without allowing UN-authorized people access to the information. E.G. A student can upload work to the college intranet which then can be marked by the tutor and then the tutor can give feedback on it and give it back to the student.
Similar benefits to Intranets.
However it is primarily used for yourself, such as uploading a document that you are working on so that you can work on it at home without having to use a memory stick removing the problem of forgetting it.
These also operate like Intranets
Training facilities are set up online as it means that you don't have to hire training staff or a facility to train them. You just need to upload work for them to do then when they complete it they can re-upload it and you can have someone mark it.
Business information is helpful online for multiple types of people. For investors it means they can see the stocks of any business while staying at home. It is good for businessmen as they can see what that company up to and see any news about them. Finally it is good for the average consumer as they can find out things like where there nearest store is and usually links to their catalog.
Domain structure is the Layout of a domain's name each website and web page has its own domain name and structure. E.G. "https://www.youtube.com/" However then each video has its own "code" or Domain structure to it afterward. Such as "feed/history" for looking at your video history.
A registrar is the company that you choose to register your domain name through. There are many ways to register a name some ISPs will do it as well.
