operational requirements
<programming> Qualitative and quantitative parameters that specify the
desired capabilities of a system and serve as a basis for determining the
operational effectiveness and suitability of a system prior to deployment.

operational semantics
<theory> A set of rules specifying how the state of an actual or
hypothetical computer changes while executing a program. The overall state is
typically divided into a number of components, e.g. stack, heap, registers etc.
Each rule specifies certain preconditions on the contents of some components and
their new contents after the application of the rule.
It is similar in spirit to the notion of a Turing machine, in which actions are
precisely described in a mathematical way.
Compuare axiomatic semantics, denotational semantics.

mission.

operation code
<programming> (Or "op code") The part or parts of a machine language
instruction which determines what kind of action the computer should take, e.g.
add, jump, load, store. In any particular instruction set certain fixed bit
positions within the instruction word contain the op code, others give
parameters such as the addresses or registers involved. For example, in a 32-bit
instruction the most significant eight bits might be the op code giving 256
possible operations.
For some instruction sets, certain values in the fixed bit positions may select
a group of operations and the exact operation may depend on other bits within
instruction word or subsequent words.
When programming in assembly language, the op code is represented by a readable
name called an instruction mnemonic.
