Linux Tutorial Series – 150 – Review

Let’s review what we learned:

• Permanent storage device is the physical device your data is stored on
• Partitions are subdivisions of the whole disk
• A filesystem is a hierarchy of files and directories you are accustomed to interacting
• Files and directories are represented as inodes
• Link is a pointer to a file or a directory
• Hard links point to the underlying data and symbolic links are like shortcuts
• Devices (represented as files) are located in the /dev folder
• Mounting is the process of attaching your device (your device’s storage) in the Linux directory structure; unmounting is the reverse process
• Unmounting is important because it writes the data in the buffer to the device
• Hash functions are used for checking file integrity
