4.2.3 Second computer (the FirstClass server)

The computer on the right of Figure 11 receives the data, manipulates it and then stores it. The computer then typically sends some kind of response back via the network, which may require the computer to retrieve some stored data.

The computer in this example is one of the Open University's FirstClass servers. A server is a computer whose hardware and software is dedicated to making data available to other computers. The FirstClass server receives the data from the network and stores it. It carries out the manipulations necessary to add your message to those already in the conference, retrieving other details about the conference as it does so. It also sends data back to you, showing you that your message is now in the conference.
