Another dumb question, but when I read these I want to be sure what is what.

I know s-video because it has a special connector.

Is Composite the RF, or coaxial cable such as RG59, RG6, etc?

Is Component the 3 different plugs of RCA type, all 3 necessary for a picture?

What do you call the single video connector that uses a RCA type connector?

Thanks again!!
