Yes as they are apart of the CPU and Fetch, Decode, Execute cycle which is usually a major part and there will most likely be questions about or related to them.

I'm not entirely sure, they don't come up in the CGP guides and the spec is a bit vague, might be a good idea to know some stuff about them.

They are not mentioned in the OCR mark scheme for a fetch, decode execute cycle question though? I'll probably learn them anyway

no i don't think so. for the fetch decode execute cycle you only need to know the von neumann architecture.
