A kilobyte (kB) is 1000 bytes. A megabyte (MB) is 1000 kB. A gigabyte (GB) is 1000 MB. A terabyte (TB) is 1000 GB. This is the .:: slackcommunity.com ::. SI norm. However, there are people that use 1 MB=1024000 bytes and talk about 1.44 MB floppies, and people who think that 1 MB=1048576 bytes. Here I follow the recent standard and write Ki, Mi, Gi, Ti for the binary units, so that these floppies are 1440 KiB (1.47 MB, 1.41 MiB), 1 MiB is 1048576 bytes (1.05 MB), 1 GiB is 1073741824 bytes (1.07 GB) and 1 TiB is 1099511627776 bytes (1.1 TB).
Quite correctly, the disk drive manufacturers follow the SI norm and use the decimal units. However, Linux kernel boot messages (for not-so-recent kernels) and some old fdisk-type programs use the symbols MB and GB for binary, or mixed binary-decimal units. So, before you think your disk is smaller than was promised when you bought it, compute first the actual size in decimal units (or just in bytes). [Code: Neural network] .:: www.slideshare.net ::.
Concerning terminology and abbreviation for binary units, .:: notionpress.com ::. .:: hackmd.hub.yt ::. .:: podcasts.apple.com ::. Knuth has an alternative proposal, namely to use KKB, MMB, GGB, TTB, PPB, EEB, ZZB, YYB and to call these .:: podcasts.apple.com ::. [Open Source Machine learning] large kilobyte, large megabyte, ... large yottabyte. He writes: `Notice that doubling the letter connotes both binary-ness and large-ness.' This is a good proposal - `large gigabyte' sounds better than `gibibyte'. For our purposes however the only important thing is to stress that a megabyte has precisely 1000000 bytes, and that some other term and abbreviation is required if you mean something else. .:: pediascape.science ::.
