Question:

What are the definitions for dominant, recessive, SOF, and EOF?

Answer:

Normally, dominant represents "low" and recessive represents "high".
Dominant is stronger than recessive on the bus. SOF, which is the abbreviation for Start-Of-Frame, indicates the start of a data frame or remote frame, and consists of one dominant bit. EOF stands for End-Of-Frame and consists of seven data bits. ACK is just one bit. Each data frame and remote frame is separated by an EOF flag consisting of seven recessive bits.
