You started a web site in Year 7 and your task now is to develop it.
Check the details on your home page and amend them if necessary. Check the hyperlinks and add, delete or update them.

We are going to write an account of how web pages and emails are delivered across the internet. We will first examine how web pages are transmitted across the internet and we will then look at emails.
As we have seen, web pages are text files that contain no 'binary' data such as you find in a spreadsheet or graphics file. Web pages are not, in the vast majority of cases, stored on your local computer, though they may be stored on a local computer in an intranet. Web pages are mainly stored on 'remote' computers, that is ones that are connected to your computer via the internet. It doesn't make much difference whether the web page you want is on a computer 5 miles or 5,000 miles away, the mechanism is the same.
You request a web page (such as this one) either by typing its URL into the address bar of your browser or by clicking on a hyperlink that is set to that address. The URL is sent to a domain name server where the address is translated from the text version that we find easy to remember into a numerical TCP/IP address. The http protocol sends a request to the
Before we write the account we are going to carry out a practical exercise
When you request a web page (cl
Web pages are one popular application of the Internet, email is another. Some claim that as many as 183 billion emails are sent every day (2 million every second), of which over 70% may be 'spam' and viruses.
How does email work? Someone who wants to send an email may use an email client such as Outlook or they may use a web-based client such as hotmail, gmail or yahoo. The mail is written and sent and appears, magically, in the receiver's mail box for them to read. How does this happen? It's all to do with servers, routers and the TCP/IP protocol...
To help trace the path of an email from one user to another we will create a working model where pupils play the role of computers and routers. When the exercise is finished you should be able to add a new section to your ICT page explaining how this process works. This will also illustrate how the Internet itself functions.
Follow the instructions on the printed sheets. Write an account of how email works on your web page.
