symmetric monoidal (∞,1)-category of spectra
A differental graded ring or dg-ring is a monoid in the category of chain complexes or of cochain complexes of abelian groups.
If a dg-ring is degreewise compatibly a vector space (or more generally a module over some ring) then it is called dg-algebra. See there for more.
