How are block devices physically addressed in a file system

In this [book](https://tldp.org/LDP/tlk/tlk.html) , the following is mentioned about filesystem addressing: > A file system does not need to concern itself with where on the physical media a block should be put, that is the job of the device's driver I have some questions related to this: 1. Do the pointers that are part of the inodes comprise of logical block indices or actual physical addresses? 1. If it is the former, then where is the mapping of block index to actual physical location stored? 1. Is there an example of how the physical addressing might look like, e.g. for an SSD device?
