Where does this topic fit? Internet concepts – Applications – Technology – Implications Internet skills – Application development – Content creation – User skills

Create Complete Analyze

Step 1: I created the survey

ServerSurvey file Save the survey on the server Is the server connected to the Internet? Where is it?

Step 2: You completed the survey

ServerYour response file Save your results on the server

Step 3: I retrieved and displayed the results

Simple – right? Where is that server? How does information get to and from the server? Is the server a computer? A person? Where was I while I was composing the survey? Where were you while you completed it? Were we using computers?

Client (me) Server Client (you) What does the cloud-shape in the center represent? A client-server application

“Server” and “Server” Server Is a server hardware or software?

“Client” and “Client” Client Is a client hardware or software?

Client ? A final question How did the client programs get into our computers?

Summary

Self-study questions I said that the Survey Gizmo server might be in Boulder Colorado, the location of the company headquarters. Might it be somewhere else? Could it be anywhere in the world? Explain your answer. I was at home when I created the survey. Could I have done it from my office at school? Could I have done it from an outdoor location like a park? Could I have done it from anywhere in the world? Explain your answer. We used Survey Gizmo as an example. Pick a competing online survey service on the Internet. Which one did you pick? How does its price compare to that of Survey Gizmo? Does it have any features that Survey Gizmo is missing?
