- hierarchical routing — The complex problem of routing on large networks can be simplified by breaking a network into a hierarchy of smaller networks, where each level is responsible for its own routing. The Internet has, basically, three levels: the backbones, the mid-levels, and the stub networks. The backbones know how to route between the mid-levels, the mid-levels know how to route between the sites, and each site (being an autonomous system) knows how to route internally. See also Exterior Gateway Protocol, Interior Gateway Protocol, transit network.

- instruction prefetch — (architecture) A technique which attempts to minimise the time a processor spends waiting for instructions to be fetched from memory. Instructions following the one currently being executed are loaded into a prefetch queue when the processor's external bus is otherwise idle. If the processor executes a branch instruction or receives an interrupt then the queue must be flushed and reloaded from the new address. Instruction prefetch is often combined with pipelining in an attempt to keep the pipeline busy. By 1995 most processors used prefetching, e.g. Motorola 680x0, Intel 80x86.

- 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.
