A yottabit is a unit of information or computer storage, abbreviated Ybit (or Yb). A bit is a binary digit, taking a value of either 0 or 1 Binary digits are a basic unit of Information storage and communication An SI prefix (also known as a metric prefix) is a name or associated symbol that precedes a unit of measure (or its symbol to form a Decimal multiple or In computing binary prefixes are names or associated symbols that can precede a unit of measure (such as a Byte) to indicate multiplication by a power of two In computing binary prefixes are names or associated symbols that can precede a unit of measure (such as a Byte) to indicate multiplication by a power of two A kilobit is a unit of information abbreviated kbit (or kb) The standard definition is 1 kilobit = 103 bit = 1000 Bit. A kibibit (a contraction of ki lo bi nary digi' t') is a unit of Information or Computer storage, abbreviated Kibit, A megabit is a unit of Information or computer storage abbreviated Mbit (or Mb) A mebibit (a contraction of mega binary digit is a unit of Information or Computer storage, abbreviated Mibit or sometimes Mib. A gigabit is a unit of information or computer storage abbreviated Gbit (or Gb) A gibibit (a contraction of gi ga bi nary digi' t') is a unit of Information or Computer storage, abbreviated as Gibit A terabit is a unit of Information or Computer storage, abbreviated Tbit (or Tb) A tebibit (a contraction of te ra bi nary digi' t') is a unit of Information or Computer storage, abbreviated Tibit or A petabit is a unit of Information or Computer storage, abbreviated Pbit (or Pb) A pebibit (a contraction of pe ta bi nary dig' it') is a unit of Information or Computer storage, abbreviated Pibit or An exabit is a unit of Information or Computer storage, abbreviated Ebit (or Eb) A exbibit (a contraction of ex a bi nary digi' t') is a unit of Information or Computer storage, abbreviated Eibit or A zettabit is a unit of Information or Computer storage, abbreviated Zbit (or Zb) In computing binary prefixes are names or associated symbols that can precede a unit of measure (such as a Byte) to indicate multiplication by a power of two In computing binary prefixes are names or associated symbols that can precede a unit of measure (such as a Byte) to indicate multiplication by a power of two Information as a concept has a diversity of meanings from everyday usage to technical settings Computer data storage, often called storage or memory, refers to Computer components devices and recording media that retain digital
1 yottabit = 1024 bits = 1,000,000,000,000,000,000,000,000 bits, which is roughly 106 (1,000,000) exabytes. A bit is a binary digit, taking a value of either 0 or 1 Binary digits are a basic unit of Information storage and communication An exabyte (derived from the SI prefix Exa -) is a unit of Information or Computer storage equal to one Quintillion
