2. 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
3. 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.
4. 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.
5. 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.
6. 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.
7. 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).
8. 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).
9. 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".
10. 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'.
11. 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.
12. 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.
