1. Chat and instant messaging Group 3

4. Instant messaging uses a programme communicating with others by connecting you to a server used by everyone who uses the same program. Once you choose someone to talk to your instant messaging program sends any messages you choose directly to the IP (internet protocol) address and port of the person you want to talk to. This is how conversations happen quickly and ‘instantly’, as you aren't sending a message to a server and back to another computer. Two computers are directly connected to each other at that point, and can send messages to each other as quickly as they choose. How does it work?

7. Something that could be improved about instant messaging is that strange people or even perverts can add you and if it is a young child using the software they will not know how to delete the contact so to improve instant messaging it should be easier to delete contacts. Another improvement of messaging could be stop viruses being sent to people as this can have negative effects on your computer and even stop them from working How could it be improved?
