This article presents a timeline of binary prefixes used to name memory units, in comparison of decimal and binary prefixes for measurement of information and computer storage.
Historically, computers have used two different approaches to memory addressing, binary and decimal. Decimal systems typically had memory configured in whole decimal multiples, e. The unit abbreviation 'K' or 'k' if it was used, represented multiplication by 1, Binary machine memory had sizes of powers of two or small multiples thereof.
In this context, 'K' or 'k' was sometimes used to denote multiples of 1, units or just the approximate size, decimal ke binary options system. From Wikipedia, the free encyclopedia. Ballistic Research Laboratories Report No. Of different relevant systems, utilize a straight binary system internally, whereas 53 utilize the decimal system primarily binary coded decimal and 3 systems utilize a binary-coded alphanumeric system of notation.

Werner Buchholzthe man who DID decimal ke binary options system the term " byte " for an 8-bit grouping. Thus Buchholz's "byte" caught on everywhere.
I myself did not like the name for many reasons. Archived PDF from the original on The 60 bits are dumped into magnetic cores on six different levels. Thus, if a 1 comes out of position 9, it appears in all six cores underneath. The 0-diagonal is pulsed first, sending out the six bits 0 to 5, of which the Adder accepts only the first four Bits 4 and 5 are ignored.
Next, the 4 diagonal is pulsed. This sends out bits 4 to 9, of which the last two decimal ke binary options system again ignored, and so on. A byte was described as consisting of any number of parallel bits from one to six. Thus a byte was assumed to have a length appropriate for the occasion. Its first use was in the context of the input-output equipment of the s, which handled six bits at a time. The possibility of going to 8 bit bytes was considered in August and incorporated in the design of Stretch shortly thereafter.
The rationale for coining the term was explained there on page 40 as follows: Byte denotes a group of bits used to encode a character, or the number of bits transmitted in parallel to and from input-output units. A term other than character is used here because a given character may be represented in different applications by more than one code, and different codes may use different numbers of bits ie, different byte sizes. In input-output transmission the grouping of bits may be completely arbitrary and have no relation to actual characters.
The term is coined from bitebut respelled to avoid accidental mutation to bit. For economy, however, the byte size was fixed at the 8 bit maximum, and addressing at the bit level was replaced by byte addressing. Digest of Technical Papers. Archived from the original PDF on Communications of the ACM. The following scheme for assigning storage for fixed-word-length arrays seems to meet these criteria and has been used successfully in working with linear arrays on a 4k IBM The data handling bit rates can be set by ground command at, or 64 bits per second decimal ke binary options system the EGO missions, or at16or 64 bits per second for the POGO missions.
