2. Yottabyte (Y) Is a multiple of the unit byte fordigital information The prefix 'yotta' indicatesmultiplication by the eighth powerof 1000 or 10^24 in th SI Therefore one yottabyte is oneseptillion bytes. The symbol of theunit is 'YB' 1YB =1000^8 bytes = 10^24 bytes A related unit, the Yobibyte (YiB),using a binary prefix, means1024^8 3. Zettabyte (Z) Is a multiple of the unit byte fordigital information The prefix zetta indicatesmultiplication by seventh power of1000 or 10^21 in the SI Therefore one Zettabyte is onesextillion bytes. The symbol is 'ZB' 1ZB =1000^7 bytes =10^21 bytes A related unit, the zebibyte (ZiB),using a binary prefiix, means1024^7 bytes 4. Exabyte (E) Is a multiple of the unit Bytefor digital information The prefix 'Exa' indicatesmultiplication by the sixthpower of 1000 or 10^18 inthe SI Therefore one Exabyte isone 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 thefifth power of 1000 and means10^15 in the SI, and therefore1 petabyte is one quadrillionbytes 6. Terabyte (T) Is a multiple of the unit Byte fordigital information The prefix 'Tera' represent forthpower of 1000, and means10^12 in the SI, and thereforeone Terabyte is one trillionbytes The unit symbol is 'TB' 1 TB= 1000000000000 bytes =10^12 byte =1000 bytes 7. Gigabyte (G) Is a multiple of the unitByte for digital information The prefix Giga means10^9 in the SI Therefore 1 Gigabyte is1000000000 byte The unit symbol for theGigabyte is 'GB' 8. Megabyte (M) Is a unit prefix in theMetric System denotinga factor of one million 10^6 = 1000000 bytes It was confirmed foruse in the InternationalSystem of Units (SI) in1960 9. Kilobyte (K) Is a multiple of the unit fordigital information orcomputer storage The prefix kilo (k) isdefined as a mutiplier of10^3 1 kilobit = 10^3 bits=1000 bits The kilobit has the unitsymbol 'kbit' or 'kb' 10. Hectobyte (h) Hecto (h) is a unit prefixin the metric systemdenoting a factor ofone hundreds (100bytes) It was adopted as amultiplier in 1795 The unit symbol in the SIis the lower case letter'h' 11. Decabyte (D) Deca is a prefix in metricsystem, also a numericalprefix, denoting a factorof ten It's symbol ''ten'' is theonly SI prefix that sesmore than one character Was a part of the originalMetric System in 1795 1000^1= 10^1 = 10 bytes 12. Byte (B) Is a unit of digital information incomputing andtelecommunication that mostcommonly consist of eight bits Historically, the byte was thenumber of beats used toenconde a single character ofa text in a computer and for This reason is the smallestaddressable unit of memory inmany computers arquitectures 13. Decibyte (d) Deci (symbol 'd') is a prefix inthe SI denoting a factor of onetenth Adopted in 1795 It's most frequent use is in thenon-SI unit The decibel is used to measuresound intensity (relative to areference) and many otherratios 14. Centibyte (c) Centi (symbol 'c') is a prefixin the metric systemdenoting a factor of onehundred It was adopted in 1795, theprefix comes from the Latinand means hundred It is mainly used with themeter to express lengths incentimeter, a common unitof length in centimeters 15. Milibyte (m) Mili (simbol 'm') is aprefix in the SI denotinga factor of onethousandth 10^-3 It was adopted in 1795 The prefix come fromthe Latin 'mille' meaningone thousand It can be a snow cristal 16. Micro () Micro (Symbol '') is a prefix inthe metric system denoting afactor of 10^-6 (one millionth) It was confirmed in 1960 The prefix comes from theGreek 'mikrs' meaning 'small' The symbol for the Micro is theletter 'mu' Is the only SI prefix which usesa character not from the Latin 17. Nano (n) Nano (symbol 'n')is an SIprefix meaning one billionth Used primarly with the metricsystem, this prefix denotes afactor of 10^-9 It is frecuently encounteredin science and electronicsfor prefixing units of timeand length 18. Pico (p) Pico (symbol 'p') is a prefixin the metric systemdenoting one trillionth, afactor of 10^-12 Derived from the Spanishpico meaning peak, beak,bit this was one of theoriginal 12 prefixes Defined in 1960 when theSI was established 19. Femto (f) Femto (symbol 'f') is a prefixin the metric systemdenoting a factor of 10^-15 Adoted by the 11thConfrence Gnrale desPoids et Mesures It was added in 1964 to theSI It is derived from the Danishword femten, meaning'fifteen' 20. Atto (a) Atto (symbol 'a') is a prefix inthe metric system denoting afactor of 10^-18 The unit multiple wasadoptedat the 12thConfrence Gnale desPoids et Measures (CGPM)in the Resolutions It is derived from the Danishword, 'atten' meaning'eighteen' 21. Zepto (z) Zepto (symbol 'z') is aprefix in the metric systemdenoting a factor of 10^-21 Adopted in 1991, itcomes from the Latin'septem', meaning 'seven'since it is equal to 1000^-7 22. Yocto (y) Yocto (symbol 'y') is a prefix in themetric system denoting a factor of10^-24 It was adopted in 1991 by theGeneral Conference on Weightsand Measures It comes from the Latin/Greek'octo' meaning 'eigth' because it is equal to 1000^-8 As of 2014, yocto is the smallestofficial SI preffix It can be used to state a subatomicparticle's mass
