there are the units of measurements of BYTE

1. Measurements units of
Bytes

2. Yottabyte (Y)
● Is a multiple of the unit byte for
digital information
● The prefix 'yotta' indicates
multiplication by the eighth power
of 1000 or 10^24 in th SI
● Therefore one yottabyte is one
septillion bytes. The symbol of the
unit is 'YB'
● 1YB =1000^8 bytes = 10^24 bytes
● A related unit, the Yobibyte (YiB),
using a binary prefix, means
1024^8

3. Zettabyte (Z)
● Is a multiple of the unit byte for
digital information
● The prefix zetta indicates
multiplication by seventh power of
1000 or 10^21 in the SI
● Therefore one Zettabyte is one
sextillion bytes. The symbol is 'ZB'
● 1ZB =1000^7 bytes =10^21 bytes
● A related unit, the zebibyte (ZiB),
using a binary prefiix, means
1024^7 bytes

4. Exabyte (E)
● Is a multiple of the unit Byte
for digital information
● The prefix 'Exa' indicates
multiplication by the sixth
power of 1000 or 10^18 in
the SI
● Therefore one Exabyte is
one quintillion bytes
● 1 EB =1000^6 bytes =
10^18 bytes

5. Petabyte (P)
● Is 10^15 of digital information.
A related unit, the pebibyte
(PiB), using binary prefix is:
1024^5 = 2^50 =
1125899906842624 bytes,
more than 12% larger
● 1PB = 10^15 bytes = 1000 TB
● The prefix 'Peta' indicates the
fifth power of 1000 and means
10^15 in the SI, and therefore
1 petabyte is one quadrillion
bytes

6. Terabyte (T)
● Is a multiple of the unit Byte for
digital information
● The prefix 'Tera' represent forth
power of 1000, and means
10^12 in the SI, and therefore
one Terabyte is one trillion
bytes
● The unit symbol is 'TB'
● 1 TB= 1000000000000 bytes =
10^12 byte =1000 bytes

7. Gigabyte (G)
● Is a multiple of the unit
Byte for digital information
● The prefix Giga means
10^9 in the SI
● Therefore 1 Gigabyte is
1000000000 byte
● The unit symbol for the
Gigabyte is 'GB'

8. Megabyte (M)
● Is a unit prefix in the
Metric System denoting
a factor of one million
● 10^6 = 1000000 bytes
● It was confirmed for
use in the International
System of Units (SI) in
1960

9. Kilobyte (K)
● Is a multiple of the unit for
digital information or
computer storage
● The prefix kilo (k) is
defined as a mutiplier of
10^3
● 1 kilobit = 10^3 bits
=1000 bits
● The kilobit has the unit
symbol 'kbit' or 'kb'

10. Hectobyte (h)
● Hecto (h) is a unit prefix
in the metric system
denoting a factor of
one hundreds (100
bytes)
● It was adopted as a
multiplier in 1795
● The unit symbol in the SI
is the lower case letter
'h'

11. Decabyte (D)
● Deca is a prefix in metric
system, also a numerical
prefix, denoting a factor
of ten
● It's symbol ''ten'' is the
only SI prefix that ses
more than one character
● Was a part of the original
Metric System in 1795
● 1000^1= 10^1 = 10 bytes

12. Byte (B)
● Is a unit of digital information in
computing and
telecommunication that most
commonly consist of eight bits
● Historically, the byte was the
number of beats used to
enconde a single character of
a text in a computer and for
● This reason is the smallest
addressable unit of memory in
many computers arquitectures

13. Decibyte (d)
● Deci (symbol 'd') is a prefix in
the SI denoting a factor of one
tenth
● Adopted in 1795
● It's most frequent use is in the
non-SI unit
● The decibel is used to measure
sound intensity (relative to a
reference) and many other
ratios

14. Centibyte (c)
● Centi (symbol 'c') is a prefix
in the metric system
denoting a factor of one
hundred
● It was adopted in 1795, the
prefix comes from the Latin
and means hundred
● It is mainly used with the
meter to express lengths in
centimeter, a common unit
of length in centimeters

15. Milibyte (m)
● Mili (simbol 'm') is a
prefix in the SI denoting
a factor of one
thousandth 10^-3
● It was adopted in 1795
● The prefix come from
the Latin 'mille' meaning
one thousand
● It can be a snow cristal

16. Micro (μ)
● Micro (Symbol 'μ') is a prefix in
the metric system denoting a
factor of 10^-6 (one millionth)
● It was confirmed in 1960
● The prefix comes from the
Greek 'mikrós' meaning 'small'
● The symbol for the Micro is the
letter 'mu'
● Is the only SI prefix which uses
a character not from the Latin

17. Nano (n)
● Nano (symbol 'n')is an SI
prefix meaning one billionth
● Used primarly with the metric
system, this prefix denotes a
factor of 10^-9
● It is frecuently encountered
in science and electronics
for prefixing units of time
and length

18. Pico (p)
● Pico (symbol 'p') is a prefix
in the metric system
denoting one trillionth, a
factor of 10^-12
● Derived from the Spanish
pico meaning peak, beak,
bit this was one of the
original 12 prefixes
● Defined in 1960 when the
SI was established

19. Femto (f)
● Femto (symbol 'f') is a prefix
in the metric system
denoting a factor of 10^-15
● Adoted by the 11th
Conférence Générale des
Poids et Mesures
● It was added in 1964 to the
SI
● It is derived from the Danish
word femten, meaning
'fifteen'

20. Atto (a)
● Atto (symbol 'a') is a prefix in
the metric system denoting a
factor of 10^-18
● The unit multiple was
adoptedat the 12th
Conférence Généale des
Poids et Measures (CGPM)
in the Resolutions
● It is derived from the Danish
word, 'atten' meaning
'eighteen'

21. Zepto (z)
● Zepto (symbol 'z') is a
prefix in the metric system
denoting a factor of 10^-
21
● Adopted in 1991, it
comes from the Latin
'septem', meaning 'seven'
since it is equal to 1000^-
7

22. Yocto (y)
● Yocto (symbol 'y') is a prefix in the
metric system denoting a factor of
10^-24
● It was adopted in 1991 by the
General Conference on Weights
and Measures
● It comes from the Latin/Greek
'octo' meaning 'eigth' οκτώ
because it is equal to 1000^-8
● As of 2014, yocto is the smallest
official SI preffix
