- java virtual machine — (language, architecture) (JVM) A specification for software which interprets Java programs that have been compiled into byte-codes, and usually stored in a ".class" file. The JVM instruction set is stack-oriented, with variable instruction length. Unlike some other instruction sets, the JVM's supports object-oriented programming directly by including instructions for object method invocation (similar to subroutine call in other instruction sets). The JVM itself is written in C and so can be ported to run on most platforms. It needs thread support and I/O (for dynamic class loading). The Java byte-code is independent of the platform. There are also some hardware implementations of the JVM.

- linear address space — A memory addressing scheme used in processors where the whole memory can be accessed using a single address that fits in a single register or instruction.

Linear addressing greatly simplifies programming at the assembly language level but requires more instruction word bits to be allocated for an address.
