First timer for me on this site. So I'm reading the ExamCram2 Network+ Second Edition. Page 89-90 about the OSI layers. For the Data-link layer it says, a "frame is used to describe the logical grouping of data at the data-link layer." On page 90 the text describes the Network layer saying, a "packet is used to describe the logical grouping of data at the data-link layer." Shouldn't packets be described at the Network layer??? Is it my misunderstanding or their typo.
