The mebibit is a multiple of the bit, a unit of information, prefixed by the standards-based multiplier mebi (symbol ''Mi''), a binary prefix meaning 220.〔International Electrotechnical Commission, IEC 60027-2 (2000-11) Ed. 2.0〕 The unit symbol of the mebibit is Mibit. : 1 mebibit = 220 bits = = 1024 kibibits〔(Definitions of the SI units: The binary prefixes )〕 This unit is most useful for measuring RAM and ROM chip capacity. The mebibit is closely related to the megabit which equals 106 bits = 1,000,000 bits. Throughout the 1980s and 1990s, video game manufacturers would sometimes report the amount of internal cartridge ROM (in megabits) on their packaging. 1 megabit equaled 128 kibibyte; 8 megabits were 1 mebibyte of ROM containing game instructions and data. ==See also== * Mebibyte * Mebibit per second 抄文引用元・出典: フリー百科事典『 ウィキペディア(Wikipedia)』 ■ウィキペディアで「Mebibit」の詳細全文を読む スポンサード リンク
