 Definitions for bytecode: The Free On-line Dictionary of Computing (27 SEP 03)
:
byte-code
A binary file containing an
executable program, formed by a sequence of op code/data
pairs.
Byte-code op codes are most often fixed size binary patterns,
but can be variable size. The data portion consists of zero
or more bits, the format of the data portion may be
determined by the identifier. The data is most often variable
in size.
In some cases, by clever design, (e.g. some RISC
instruction sets) the identifier/data pair is a fixed size.
This can provide performance benefits.
A byte-code program is normally interpreted by a {byte-code
interpreter}. The advantage of this technique compared with
outputing machine code for a particular processor is that
the same byte-code can be executed on any processor on which
the byte-code interpreter runs. The byte-code may be compiled
to machine code ("native code") for speed of execution but
this usually requires significantly greater effort for each
new taraget architecture than simply porting the interpreter.
For example, Java is compiled to byte-code which runs on the
Java Virtual Machine.

Bytecode is a term which has been used to denote various forms of instruction sets designed for efficient execution by a software interpreter as well as being suitable for further compilation into machine code.
