World wide web- The World Wide Web is created from a great number of internet servers. There are many different web pages that will be stored and hosted on the webserver. When these are all put together create the World Wide Web. If you are using the www you still need to use a web browser to view the pages.
Internet service providers (ISP) – An ISP will be able to supply the internet connection to the internet servers. This will allow you to connect to (www.) Websites. If you are trying to connect to a specific website both the host and receiver needs an ISP to connect to each other. Examples of ISP are BT, Virgin, and Talk Talk. All of these companies will provide you with either telephone lines or fibre optic cables for you to be able to connect to their internet server.
Web hosting services- Websites that are put on the internet have to be put on a web server, these webservers are connected to the internet. There are many organisations that you can pay monthly for them to host your website. Larger companies and organisations will purchase their own servers to host their websites on because it will work out cheaper in the long run also they can perform their own maintenance. Web hosting companies can offer many services, they can store your website on their server, upload it so it can be accessed by www. , offer technical support if any problems occur with your website and also offer you an email address.
Domain name structure- every website is found recognized by a unique address this is called an IP address, a ip address can be for a website, server, computer, laptop, mobile. Any device that can connect to the internet will have an IP address. IP addresses are made up of 4 groups and from 9-11 numbers for example (192.168.0.2). Because these numbers are hard to remember a domain name will be put in place to access websites and example would be www.google.com.
Domain name servers- Domain names are the unique address for where the files for the website are kept and hosted. If you are requesting to go on website your request is sent to the domain server this then will find the website you are looking for and request for the website. A Domain name server is like a telephone book of websites. If it cannot find the domain name you are looking for it will send the request to another domain name server.
Web servers – if you want to access your website over the World Wide Web you will have to upload your website to a web server. A web server could be hardware or software these should be able to allow HTML pages to be shown. Web servers are connected to the internet they have high communication lines and high speed routers.
Mail servers-
A mail server is where all of your emails are kept for local users. It also takes rules from the sender of how the email should show the receiver for example how the email should look. When the email is sent, it is transferred to other mail servers until it reaches the destination.
Routers-
To create a network you will need a router, these connect devices together which creates a network. A router lets packets which are files to be passed around the network until it reaches the user. When a request it put out for a website the request is passed through routers until it reaches the webserver. After this the web server sends back the request back to the computer back through routers.
Web Browsers-
A web browser is software that allows you to access web pages. It gets the web pages from the World Wide Web. Most new web browsers allow you to play videos and sound because they have the newest software included. Web servers send the request of the website to the router; the router sends the request to a webserver but uses other routers to get to the destination. When the web server is reached and the request is sent back to the computer the browser turns the packets that are received into a webpage that you can view.
Email software-
There are many examples of email software for example Outlook, Mozilla thunderbird and Gmail. With this software you can create send and receive emails. Most emailing software have a stronger security to stop you from receiving spam and phishing emails. These software’s can allow you sort and manager your emails. You can use this software to send automatic emails when you are not in the office or at your desk to inform your contacts when the email you that you are not in the office or on holiday.
Bellow is a image that shows how the internet is connected the browsers are the users of computers or any device that can connect to the internet. The computers are always connected to a ISP and these are connected to the servers of the hosts.
