Byte explicitly denotes a sequence of eight bits, eliminating the ambiguity of the byte. The term "byte" was coined by Werner Buchholz in June 1956, during the early design phase for the IBM Stretch computer, which had addressing to the bit and variable field length (VFL) instructions with a byte size encoded in the instruction. It is a deliberate respelling of "bite" to avoid accidental mutation to "bit". Another origin of "byte" for bit groups smaller than a machine's word size (and in particular groups of four bits) is on record by Louis G. Dooley, who claimed he coined the term
Interpreter (computing) has been tested and debugged under the interpreter it can be compiled and thus benefit from faster execution while other routines are being developed. Many interpreters do not execute the source code as it stands but convert it into some more compact internal form. Many BASIC interpreters replace keywords with single byte tokens which can be used to find the instruction in a jump table. A few interpreters, such as the PBASIC interpreter, achieve even higher levels of program compaction by using a bit-oriented rather than a byte-oriented program memory structure, where commands tokens occupy perhaps 5 bits, nominally "16-bit"
