About these units
Megabit (Mb)
A megabit equals 1,000,000 bits, a standard networking unit used to express data transfer rates. Internet speeds—both broadband and wireless—are typically quoted in megabits per second (Mbps). Because communication systems often care more about transfer rates than storage quantities, the megabit became a natural standard long before modern high-speed networks. The distinction between megabits (Mb) and megabytes (MB) is crucial, as confusing the two leads to misunderstandings about download times. Megabits remain central to evaluating network performance, streaming quality, and bandwidth provisioning.
Block (block)
A block is a unit of data storage used by file systems, typically ranging from 512 bytes to 4096 bytes, though advanced systems may use even larger sizes (8 KB, 16 KB, etc.). Blocks form the fundamental allocation unit for disk storage—files occupy blocks on disk, and file systems track which blocks belong to which files. Block size has significant performance implications. Larger blocks improve read/write throughput but may waste space for small files (internal fragmentation). Smaller blocks offer precision but reduce I/O efficiency. Many classic file systems (FAT, ext2), modern ones (ext4, NTFS), and network storage systems (ZFS, Btrfs, distributed file systems) all rely on block-based allocation. Blocks bridge the gap between raw physical storage and abstract file structures.
