2 Route2 Inner layer (signal or supply) - tracks on an inner layer
3 Route3 Inner layer (signal or supply) - tracks on an inner layer
4 Route4 Inner layer (signal or supply) - tracks on an inner layer
5 Route5 Inner layer (signal or supply) - tracks on an inner layer
6 Route6 Inner layer (signal or supply) - tracks on an inner layer
7 Route7 Inner layer (signal or supply) - tracks on an inner layer
8 Route8 Inner layer (signal or supply) - tracks on an inner layer
9 Route9 Inner layer (signal or supply) - tracks on an inner layer
10 Route10 Inner layer (signal or supply) - tracks on an inner layer
11 Route11 Inner layer (signal or supply) - tracks on an inner layer
12 Route12 Inner layer (signal or supply) - tracks on an inner layer
13 Route13 Inner layer (signal or supply) - tracks on an inner layer
14 Route14 Inner layer (signal or supply) - tracks on an inner layer
15 Route15 Inner layer (signal or supply) - tracks on an inner layer
16 Bottom Tracks, bottom side - tracks on the bottom side
17 Pads Pads (through-hole) - pads for a through-hole
18 Vias Vias (through-hole) - vias for a through-hole
19 Unrouted Airwires (rubberbands) - unrouted airwires, wires that are "in the air", so you know they have to be routed yet
20 Dimension Board outlines (circles for holes) - dimensions for various components on the board, or the board itself
21 tPlace Silk screen, top side - silk screen on the top side, you know, letters and stuff
22 bPlace Silk screen, bottom side - silk screen on the bottom side, can you guess?
23 tOrigins Origins, top side - origin, as in the beginning, maybe a reference point of some sort
24 bOrigins Origins, bottom side - origin, as in the beginning, maybe a reference point of some sort
25 tNames Service print, top side, I could go on but I'm not going to go on
26 bNames Service print, bottom side, maybe this link will help

27 tValues Component VALUE, top side, maybe this link will help also

28 bValues Component VALUE, bottom side, but if that fails

29 tStop Solder stop mask, top side, by now there should be some good info presented
30 bStop Solder stop mask, bottom side, by now the O/P should have started doing some reading
31 tCream Solder cream, top side, and should have a good idea of what's what
32 bCream Solder cream, bottom side, and by now I start stopping
33 tFinish Finish, top side, and I've stopped
34 bFinish Finish, bottom side, and left the rest of the layers to the O/P's imagination
35 tGlue Glue mask, top side, yep done
