Computing

 

k and greater are common in computing, where they are applied to information

and storage units like the bit and the byte. Since these come in powers of

two, the prefixes' meaning changes:

 

K = 210 = 1,024

M = 220 = 1,048,576

G = 230 = 1,073,741,824

T = 240 = 1,099,511,627,776

P = 250 = 1,125,899,906,842,624.

 

However, these prefixes usually retain their powers-of-1000 meanings when

used to describe rates of data communication (bit rates): 10-Mb/s Ethernet

runs at 10,000,000 bits per second, not 10,485,760 bit/s.

 

This inconsistency did not seem relevant when computers had little storage

and communication links were relatively slow, but the increasing capacity of

computing systems and speed of network links began making this inconsistency

a more serious problem.

 

Accordingly, the International Electrotechnical Commission adopted new

binary prefixes in 1998, formed from the first syllable of the decimal

prefix plus 'bi' (pronounced 'bee'). The symbol is the decimal symbol plus

'i'. So now, one kilobyte (1 kB) equals 1000 bytes, whereas one kibibyte (1

KiB) equals 210 = 1024 bytes. Likewise mebi (220), gibi (230), tebi (240),

pebi (250), and exbi (260). For example, at 1 MB/s = 106 bytes per second,

it would take slightly longer than one second to transfer an object 1 MiB =

220 bytes in size. The adoption of these prefixes is somehow very limited.

Hmm, kanskje du burde endret innlegget litt, slik at det tar hensyn til at du har mistet tekstformateringen som gjør at eksponentene vises som eksponenter? ("K=210...").

Dette har jo vært kjent lenge.

 

k = kilo = 10^3 = 1 000

M = Mega = 10^6 = 1 000 000

G = Giga = 10^9 = 1 000 000 000

T = Terra = 10^12 = 1 000 000 000 000

 

Ki = kilobinær (kibi) = 2^10 = 1 024

Mi = megabinær (mebi) = 2^20 = 1 048 576

Gi = gigabinær (gibi) = 2^30 = 1 073 741 824

Ti = terrabinær (tebi) = 2^40 = 1 099 511 627 776

jeg trodde igrunnen dette var almenkjent kunskap dette her

(muligens feil ordvalg(er ikke helt sikker så jeg lar det stå))
