Storage

/ˌfæt ˈtwɛlv/

noun — "early File Allocation Table filesystem."

FAT12, short for File Allocation Table 12, is the original variant of the FAT filesystem family, using 12-bit cluster addressing to manage storage on floppy disks and small-volume drives. It organizes data into clusters and tracks their allocation in a linear table, providing a simple yet effective method for file storage and retrieval.

noun — "file allocation table filesystem family."

FAT, short for File Allocation Table, is a family of disk filesystems designed to organize, store, and retrieve files on block-based storage devices using a table-driven allocation scheme. Variants include FAT12, FAT16, and FAT32, each defined by the number of bits used to address clusters. FAT abstracts physical storage layout into logical cluster sequences, enabling operating systems and firmware to manage files without hardware-specific knowledge.

/ˌfæt ˈsɪksˌtiːn/

noun — "legacy File Allocation Table filesystem."

FAT16, short for File Allocation Table 16, is a legacy filesystem that organizes data on block-based storage devices using a 16-bit cluster addressing scheme. It was widely used in early personal computers and embedded devices due to its simplicity, low overhead, and compatibility across operating systems and firmware environments.

/ˌfæt θɜːrtiˈtuː/

noun — "widely compatible file allocation table filesystem."

FAT32, short for File Allocation Table 32, is a disk filesystem designed to organize, store, and retrieve files on block-based storage devices using a table-driven allocation model. It represents an evolution of earlier FAT variants and is defined by its use of 32-bit cluster addressing, allowing larger volumes and files than its predecessors while maintaining broad hardware and software compatibility.

/ˈlɒdʒɪkəl blɒk ˈædrɛs/

noun — "linear addressing scheme for storage blocks."

/dɪsk ˈpɑːr tɪʃənɪŋ/

noun — "dividing a storage device into independent sections."

Disk Partitioning is the process of dividing a physical storage device, such as a hard drive or solid-state drive, into separate, logically independent sections called partitions. Each partition behaves as an individual volume, allowing different filesystems, operating systems, or storage purposes to coexist on the same physical disk. Partitioning is a critical step in preparing storage for operating system installation, multi-boot configurations, or structured data management.

/ˈpɑːr tɪʃən ˈteɪbəl/

noun — "map of disk partitions for storage management."

Partition Table is a data structure on a storage device that defines the organization and layout of disk partitions, specifying where each partition begins and ends, its type, and other attributes. It serves as the roadmap for the operating system and firmware to locate and access volumes, enabling multiple filesystems or operating systems to coexist on a single physical disk.

/ɡaɪd pɑːrˈtɪʃən ˈteɪbəl/

noun — "modern disk partitioning standard with large capacity support."

/ˌɛm biː ˈɑːr/

noun — "first sector of a storage device containing boot information."

MBR, short for Master Boot Record, is the first sector of a storage device, such as a hard disk or solid-state drive, that contains essential information for bootstrapping an operating system and managing disk partitions. It occupies the first 512 bytes of the device and serves as a foundational structure for legacy BIOS-based systems, providing both executable boot code and a partition table.

noun — "central table of file metadata."
