    %% Physical Layer
    SD[STORAGE DEVICE: Piece of hardware used to store data] --> Comp[Composed of]
    Comp --> Drive[DRIVE: Part of device responsible for reading/writing. Now used to indicate media where data is stored.]
    Comp --> Disk[DISK: Media where we store data. Name from old devices that were actually disks.]
    
    Drive --- Note1[In modern slang these are equivalent]
    Disk --- Note1

    %% Partitioning Layer
    SD --> Partition[PARTITION: Logical software defined boundaries on a drive. Useful to use multiple file systems on one device.]
    
    Partition --> GPT[GPT: GUID Partition Table]
    Partition --> MBR[MBR: Master Boot Record]

    %% File System Layer
    Partition --> FS[FILE SYSTEM: A strategy on how we manage files in a partition]
    FS --> XFS[XFS]
    FS --> ZFS[ZFS]
    FS --> EXT4[EXT4]

    %% Directory & Mounting
    Inode[INODE: data structure in a unix file-system that describes...]
    Dir[DIRECTORY: Type of inode used to organize files, links, and other directories]
    File[FILE: Type of inode]
    Link[LINK: ]
    Mount[MOUNT POINT: Directory where we mount a file system, partition, or storage device]
    
    FS -.-> Inode
    Inode --> Dir
    Inode --> File
    Inode --> Link
    Dir --> Mount
    %% FS --> Mount

    %% Logical Volume Management (LVM)
    Partition -- "Used to build" --> PV[PHYSICAL VOLUME: A partition + a file system]
    PV -- "Multiple PVs form" --> VG[VOLUME GROUP: Aggregation of PVs]
    VG -- "Multiple" --> LV[LOGICAL VOLUME: Aggregation of PVs]
