In biology, nucleosides are "purine or pyrimidine bases attached to a ribose or deoxyribose."[1]

Purine or pyrimidine bases (nucleobases) attached to ribose are called ribonucleosides.
Purine or pyrimidine bases (nucleobases) attached to deoxyribose are called deoxynucleosides.
A nucleotide is a nucleoside (a purine or pyrimidine base plus a pentose sugar) with a phosphate group added.
