CST 334 Week 7

This week our module focused on persistence. Specifically, the readings discussed persistent storage. A persistent storage device can include a hard disk drive or even a solid state storage device. It can be managed through a file system. The readings for this week also went pretty in-depth regarding files and directories. I learned file system basics, that included information on how data is managed and how structurally data is stored, retrieved and managed using this system. This file system structure was discussed, including inodes, file descriptors and the overall directory structure. Later in the readings, it outlined how the file system is implemented, including additional information on inodes and file allocation tables, which are essential to organizing files on storage devices. Inodes store metadata about files and pointers to data blocks. File allocation was also discussed in the text, including link file allocation which is a method where files are stored as a linked list of disk blocks.
