Novice SLR, C3, C2, C 1, B, M, AV, TV, A+ all mean something. Please explain it simply and understand it. I want to find a friend to learn.

B door, you can set any exposure time.

M, full manual

AV aperture priority

Television shutter priority

SV sensitivity priority

P gear, automatic gear

This is the gear of different SLR brands.

C 1, C2 and C3 should be personal setting options. There is no * * * for different SLR.

Start with the SLR and just read the instructions.
