  2. File size - Wikipedia

    en.wikipedia.org/wiki/File_size

    File size is a measure of how much data a computer file contains or how much storage space it is allocated. Typically, file size is expressed in units based on byte. A large value is often expressed with a metric prefix (as in megabyte and gigabyte) or a binary prefix (as in mebibyte and gibibyte). [1]

  3. Kilobyte - Wikipedia

    en.wikipedia.org/wiki/Kilobyte

    The internationally recommended unit symbol for the kilobyte is kB. [ 1 ] In some areas of information technology , particularly in reference to random-access memory capacity, kilobyte instead typically refers to 1024 (2 10 ) bytes.

    34,359,738,368 bits (4 gibibytes) – maximum addressable memory for the Motorola 68020 (1984) and Intel 80386 (1985), also the volume size limit for the FAT16B file system (with 64 KiB clusters) as well as the maximum file size (4 GiB-1) in MS-DOS 7.1-8.0. 3.76 × 10 10 bits (4.7 gigabytes) – capacity of a single-layer, single-sided DVD: 2 36

  6. File Allocation Table - Wikipedia

    en.wikipedia.org/wiki/File_Allocation_Table

    The maximal possible size for a file on a FAT32 volume is 4 GB minus 1 byte, or 4,294,967,295 (2 32 − 1) bytes. This limit is a consequence of the 4-byte file length entry in the directory table and would also affect relatively huge FAT16 partitions enabled by a sufficient sector size.

  7. Disk sector - Wikipedia

    en.wikipedia.org/wiki/Disk_sector

    In computer file systems, a cluster (sometimes also called allocation unit or block) is a unit of disk space allocation for files and directories.To reduce the overhead of managing on-disk data structures, the filesystem does not allocate individual disk sectors by default, but contiguous groups of sectors, called clusters.
