Book typo or is it correct???

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.

I have that exact book and yes, it is a typo.

Packets are the PDU's at the Network layer, not the Data-Link layer.

Frames are at the Data-Link.

are there any other typos that you might have come across??? There should be a sticky about the typos in these study materials.
