Funny characters in terminal?

[fliptomato]

Hi everyone, apologies in advance that this is a complete beginner's question. I recently opened terminal and found that the prompt looks a bit funny:

[COLOR="Green"]mq67[/COLOR]:~ mycomputername$

(where "mycomputername" is the name I gave my computer). I don't recall ever seeing the "mq67" before, however, and was wondering where it came from and how to change it back to something more sensible?

Also, when I open terminal I get the following line:

[Last login: Thu Aug  7 16:07:29 on [COLOR="Green"]ttys000[/COLOR]

What does the ttys000 mean?

Any assistance would be appreciated. I don't remember these weird values being there.

tty is another name for the terminal. ttys must mean tty service or is your telnetting to a remote system called ttys.
