What is the difference between a phenyl ring and a benzene ring

From what I've seen they look pretty similar, so whats the difference?
Am I correct in saying that a phenyl is the same as a benzene where one of the H's has been replaced with another functional group?

Thnaks :)

Benzene and phenyl seems look the same because they are both aromatic and all aromatic compounds are based on benzene C6H6. Phenyl or phenyl functional group is a hydrocarbon derived from benzene by removing 1 H, making it a C6H5 then attaching it to something else.

Phenyl is a group. Typically a subsituent if you are naming organic compounds. But yes, you're thinking is correct. Benzene is C6H6.

Phenyl is an aromatic ring with formula C6H5 attached to some R group.

a phenyl ring is merely a benzene ring with a substituent coming off it while a benzene ring has no substituents coming off it, hope that clarifies.
