Who coined the term "kilobyte"?
« on: August 23, 2019, 11:43:47 PM »
Claude E. Shannon first used the word "bit" in his seminal 1948 paper A Mathematical Theory of Communication. He attributed its origin to John W. Tukey, who had written a Bell Labs memo on 9 January 1947 in which he contracted "binary information digit" to simply "bit".
The term "byte" (binary term) was coined by Werner Buchholz in June 1956, during the early design phase for the IBM Stretch computer.
But who first coined and used the terms "kilobyte", "gigabyte", "terabyte"?

Hi, jimg, thank you!

U.S. Patent 3,638,185 HIGH DENSITY PERMANENT DATA STORAGE AND RETRIEVAL SYSTEM is filed on March 17, 1969, earliest Google Patent search containing "kilobyte")
"The data word processor 606 handles the inflow and out-flow of byte-oriented input/output data and interleaved signals at a rate of, for example, 500 kilobytes per second. Instruction processing rates of four to eight per microsecond are required for such a data flow."
U.S. Patent 3,618,041 Memory Control System is filed on October 29, 1969
"FIG. 2a shows a practical example of an operand address which consists of, for example 24 bits. It is assumed herein that each block includes 32 bytes, each sector includes 1 kilobyte, the buffer memory 116 includes 4 kilobytes, and read data is represented by one double word or 64 bits, as one word in this case consists of 32 bits."
But WHO first coined and used the terms "kilobyte", "gigabyte", "terabyte"?

but who coined nibble?(halfbyte) ,was it someone who used hexadecimal who started naming the figures nibble,or was it intel when they made the first 4bit calculator cpu?

Hi, daydreamer!
In 2014, David B. Benson, a professor emeritus at Washington State University, remembered that he playfully used (and may have possibly coined) the term nibble as "half a byte" and unit of storage required to hold a binary-coded decimal (BCD) decimal digit around 1958, when talking to a programmer of Los Alamos Scientific Laboratory. Another early recorded use of the term 'nybble' was in 1977 within the consumer-banking technology group at Citibank. It created a pre-ISO 8583 standard for transactional messages between cash machines and Citibank's data centers that used the basic informational unit 'NABBLE'.
Historically, there are cases where nybble was used for a group of bits greater than 4. In the Apple II microcomputer line, much of the disk drive control and group-coded recording was implemented in software. Writing data to a disk was done by converting 256-byte pages into sets of 5-bit (later, 6-bit) nibbles and loading disk data required the reverse.[11][12][13] Moreover, 1982 documentation for the Integrated Woz Machine refers consistently to an "8 bit nibble".[14] The term byte once had the same ambiguity and meant a set of bits but not necessarily 8, hence the distinction of bytes and octets or of nibbles and quartets (or quadbits). Today, the terms 'byte' and 'nibble' almost always refer to 8-bit and 4-bit collections respectively and are very rarely used to express any other sizes.
