What does these parts of the camera do in a Nikon D60 camera?

I need to know what these parts do:
- Self timer lamp
- Focal plane mark
- Flash mode Button
- Eylet for camera strap
- USB port
- Fn. Function Button
- Lens release button
- Lens mounting index
- Lens Glass
- Focal ring
- Zoom ring
- Infared receiver

Thank you very much. +10 for the person who helps me: D

Homework time again?

Man all that stuff is in your user manual, and unless you read the manual and play with your camera a couple of hours each night for a few weeks, you will be clueless of how to use your camera and lenses

We can't help you if you want to learn how to use your fine camera.

If for some reason you do not have the user manual, you can download it from Nikon
