Understanding of web architecture and components:
Show your understanding of the internet by detailing the various stages and processes that information must pass through to get from server to screen, represent this in a flow diagram with additional notes, you must try to include the following:
Web architecture:
Internet Service Providers (ISP); web hosting services; domain structure; domain name registrars; worldwide web
Components:
hardware eg web, mail and proxy servers; routers; software eg browser, email
Domain name registrar
there are many sites online that you can buy a domain name from one that i personally like is godaddy.com because you can get a domain for 2 years for as little as £5 the domain name is a vital part of a website as this is how people will find your site online and this is the name of your site and only you own the rights to that domain name
Worldwide web
the world wide web is millions and millions of documents that you can access through the internet and you can navigate the internet using search engines like google ask and bing the pages that you visit can have different types of files such as text audio and video you will move between pages one link at a time
Browser
Web browsers are a networks of information resources on the world wide web. A source is identified by a uniform resource identifier mainly seen as a URI, this is a webpage, image, video or any other piece of content available on the web or webpage. the webpage is what lets the user view and send information with ease and it makes it so it is simple and easy to do
Web servers
web servers can be known as hardware as well as a form of software for the computer. because the inter gives internet access to the user it can provide content for the user. this content varies from Facebook and YouTube to many other webpages, webpages deliver using the HTTP. the HTML documents along with any other content is delivered by the use of HTTP.
Router
the router is the external hardware that all computers must connected via wireless or wired to connect to there networking package. the router will split its self among all the other devices connected to the router, it will spread the package in either and efficient way depending on the amount of data needed or it will split the data equally.
Email
Emailing is were two or more people send information / data such as text or images this is done through an email address and everyone with an email adress has a unique one to them so if you have someones email address unless you personally put the information in wrong the onl;y person that can recive that data is the person you intend to.
Web 2.0
Web 2.0 is where web pages changed from html web pages to more interactive webpages that you can link and share other pages to well other internet users. YouTube and Facebook are a good example of websites where people share and link as well as constantly update the webpage. this is considered a more dynamic website which is considered the second generation of websites.
Cloud computing
there are many website that use cloud storage and i personally thing it is a great idea because you can store personal files in a place were you can always have access to them when you need to for example i have drop box this stores my files and only when i put my email and password in i can view and download them so i like to keep useful information such as my cv online so if i ever need it i can have access to it through any computer

Web hosting services
there are many companies that will provide space on their servers for people to host there websites and
this comes at a cost.all data has to be stored somewhere and what the hosting service does is it makes it so people can visit your site and download the data and upload there information this will cost the owner of the site if there go over there data cap and the company will charge to maintain the site a site that i like to use is called hostgator i like this site because they have an easy to use site so everything is easy to understand and they have low prices and all of this with a 99.9% up time so that means that there is next to no chance tnhat your website will go offline
Domain structure
a domain structure is where there are a group of computers which are all linked and have to manage there accounts and security. you would have to use your login and password to get onto this domain and access its servers also you will be able to send and receive data this is helpful when you are using a local network such as a company network so everyone in the building will be connected and be able to have access to information that they may need
