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.

YOCTOBYTE

• YOCTOBYTE:• Yocto (symbol y) is a prefix in the International

System indicating a factor 10^-24. • Adopted in 1991, comes from Greek, meaning

eight, because it is equal to 1/1000^8.• Is the smallest unit of information used in

computers.
