be provided through the use of magnetic drum storage units, each having a capacity of 60,000 characters." "A character may be a letter of the alphabet, a decimal number, or any of eleven different punctuation marks or symbols used in report printing." "Each one of the 10,000 positions of memory is numbered from 0000 to 9999 and each stored character must occupy one of these positions." (page 8) The word byte, meaning eight bits, is coined by Dr. Werner Buchholz in June 1956, during the early design phase for the IBM Stretch computer. IBM 650 RAMAC (a decimal addressed machine) announcement "The 650 RAMAC combines the IBM 650 Magnetic Drum Data Processing Machine with a series of disk memory units which are capable of storing a total of 24-million digits. The 305 RAMAC is an entirely new machine which contains its own input and output devices and processing unit as well as a built-in 5-million-digit disk memory." 1957 The IBM 705 (a decimal addressed machine) Operating manual uses decimal arithmetic for powers of ten, without prefixes. "A total of 40,000 characters can be stored within the main storage unit of the Type 705." "Each one of the 40,000 positions in memory is numbered from 0000 to 39,999." (page 17) "One or more magnetic drums are available as optional equipment with a capacity of 60,000 characters each." Lewis, W. D., Coordinated broadband mobile telephone system Earliest instance of "kilobit" in both IEEE explore and Google Scholar: "Central controls the mobile link with a rate of 20 kilobits per second, or less". 1958 "64 million (226) bytes" is used in a memo by Dr. Werner Buchholz 1959 The term 32k is used in print to refer to a memory size of 32768 (215). The author is with the Westinghouse Electric Corporation. 1960s 1960 The 11th Conférence Générale des Poids et Mesures (CGPM) announces the Système International d'Unités (SI) and adds the decimal metric prefixes giga, and tera, defined as 109 and 1012 Frequency Diversity Communications System is filed on May 13, 1960: "In actual construction, the delay line, which provides a total delay from one end to the other of one baud (10 microseconds for a 100 kilobit per second information rate), may be fabricated from lumped parameter elements, i.e., inductors and capacitors, in a well-known manner." "At a 100 kilobit per second information rate, both mark and space signals will generally
