MEASUREMENT UNITS OF BYTE
Yottabyte, zettabyte, exabyte, petabyte, terabyte, gigabyte,
megabyte, kilobyte, byte, hectobyte, decabyte, decibyte, octabyte, milibyte, microbyte, nanobyte, picobyte, femtobyte, attobyte, zeptobyte & yoctobyte.
YOTTABYTE & ZETTABYTE
• ZETTABYTE:• 1000 exabytes equals one
zettabyte. • One zettabyte is a unit of
storage whose symbol is the ZB, equivalent to 10^ 21 bytes.
• For the computer are often confused with 2^70 which is called zebibyte.
• YOTTABYTE:• One yottabyte is a
storage unit whose symbol is YB, equal to 10^24 bytes.
• There is some confusion with respect to this measure (10^24 bytes) and 2^80 bytes
EXABYTE & PETABYTE
• PETABYTE: • A petabyte is a unit of
storage whose symbol is the PB, and equal to 10^15 bytes = 1,000,000,000,000,000 bytes. Prefix peta comes from Greek, meaning five, equivalent to 1000^5 or 10^15.
• EXABYTE: • 1000 petabytes equals
one exabyte. • An exabyte is a unit of
measurement of information storage EB whose symbol is the equivalent to 10^18 bytes.
TERABYTE & GIGABYTE
• TERABYTE:• a terabyte is a unit of
storage whose symbol is the TB, and is equivalent to December 10 bytes.in computing is often confused with 2^40, but it is an error because the value is called tebibyte.
• 1 tb = 10^3 gb = 10^6 mb = 10^9 kb = 10^12 bytes
• GIGABYTE:• A gigabyte is a unit of
storage whose symbol is the GB, equivalent to 109 (billion) bytes. Often confused with 230 bytes. The term comes from the Greek meaning giant.
MEGABYTE & KILOBYTE
• MEGABYTE: • is a multiple of the
unit byte for digital information. Its symbol is MB. The unit prefix mega is a multiplier of 1000000 (10^6) in theInternational System of Units (SI).Therefore one megabyte is one million bytes of information.
• KILOBYTE: • a kilobyte is a storage
unit whose symbol is equivalent to 10^3 kb and bytes, although the Greek prefix kilo means thousand, the term kilobyte and symbol kb have been used historically.
BYTE & HECTOBYTE• HECTOBYTE:• Hecto or hecta is a unit
prefix in the metric system denoting a factor of one hundred., hekaton, meaning hundred. Its unit symbol in the International System of Units (SI) is the lower case letter h.
• BYTE:• 1 byte is equivalent to
byte (i.e. eight bits) to right ends, a byte must be considered as a sequence of contiguous bits, whose size depends on the code information and the character code that is defined.
DECABYTE & DECIBYTE
• DECABYTE:• Deca (symbol da) is a
prefix in the metric system denoting a factor of 10¹ to 10.
• For example: • decameter = 10 meters
• DECIBYTE: • Deci (symbol d) is a
prefix in the system denoting a factor of 10^-1 (1/10).
CENTIBYTE & MILIBYTE
• CENTIBYTE:• Centi (symbol c) is a
prefix in the International System indicating a factor 10^-2 or 1/100.
• MILIBYTE: • Mili (symbol m) is a prefix
in the system denoting a factor of 10^-3 or 1/1 000 Adopted in 1795, derives from the Latin word mille "thousand" (his plural milia).
MICROBYTE & NANOBYTE
• MICROBYTE:• The word Micro is a
prefix in the International System indicating a factor of 10 ^-6.
• Aside always represented with the specific sign (µ ), which comes from the Greek word (mikrós) and it means 'small'.
• NANOBYTE:• Nano (symbol n) is a
prefix in the system denoting a factor of 10^-9.
• Confirmed in 1960, comes from Greek, meaning "dwarf".
PICOBYTE & FEMTOBYTE
• PICOBYTE:• Pico (symbol p) is a
prefix in the system denoting a factor of 10^-12.
• It comes from the Italian word piccolo, meaning "small".
• FEMTOBYTE:• Femto (symbol f) is a
prefix in the system denoting a factor of 10^-15.
• The origin of this prefix is femten Danish word that means 'fifteen'.
ATTOBYTE & ZEPTOBYTE
• ATTOBYTE:• Atto (a1 symbol) is a
prefix in the International System indicating a factor 10^-18. The origin of this prefix is the Danish word atten, meaning "eighteen".
ZEPTOBYTE: • Zepto (symbol z) is a
prefix in the International System indicating a factor 10^-21.
• Adopted in 1991, comes from the Latin septem, meaning "seven", as it is equal to 1/1000^7.
