Getting Started

Today, I got a basic idea about information systems. My teacher used the example of the My School website in order to make us understand about the different parts of an information system. The activity which is supposed to be completed, is choosing one other type of information system, such as a Mobile Phone, Library Database or GPS Navigation and accordingly completing the diagram.
The Information System I am doing is: GPS Navigation.
Unfortunately I am unable to get onto the school website, where I can download the PDF file and add my own notes. So using the help of my IPT book, where the parts of an information system are given, I'll complete the activity but not in diagram form. When at school, ill then download the diagram and transfer my notes onto their and put it on my blog.
