12-letter words containing c, o, a, h, m, n
- hamming code — (algorithm) Extra, redundant bits added to stored or transmitted data for the purposes of error detection and correction. Named after the mathematician Richard Hamming, Hamming codes greatly improve the reliability of data, e.g. from distant space probes, where it is impractical, because of the long transmission delay, to correct errors by requesting retransmission.

- harmonic law — any one of three laws governing planetary motion: each planet revolves in an ellipse, with the sun at one focus; the line connecting a planet to the sun sweeps out equal areas in equal periods of time (law of areas) or the square of the period of revolution of each planet is proportional to the cube of the semimajor axis of the planet's orbit (harmonic law)
- harmonically — pertaining to harmony, as distinguished from melody and rhythm.
- harmonichord — a musical instrument resembling an upright piano intended to fuse the sound of a violin with the functionality of a piano, the tone therefore produced using friction rather than through striking

- machine code — (language) The representation of a computer program that is read and interpreted by the computer hardware (rather than by some other machine code program). A program in machine code consists of a sequence of "instructions" (possibly interspersed with data). An instruction is a binary string, (often written as one or more octal, decimal or hexadecimal numbers). Instructions may be all the same size (e.g. one 32-bit word for many modern RISC microprocessors) or of different sizes, in which case the size of the instruction is determined from the first word (e.g. Motorola 68000) or byte (e.g. Inmos transputer). The collection of all possible instructions for a particular computer is known as its "instruction set". Each instruction typically causes the Central Processing Unit to perform some fairly simple operation like loading a value from memory into a register or adding the numbers in two registers. An instruction consists of an op code and zero or more operands. Different processors have different instruction sets - the collection of possible operations they can perform. Execution of machine code may either be hard-wired into the central processing unit or it may be controlled by microcode. The basic execution cycle consists of fetching the next instruction from main memory, decoding it (determining which action the operation code specifies and the location of any arguments) and executing it by opening various gates (e.g. to allow data to flow from main memory into a CPU register) and enabling functional units (e.g. signalling to the ALU to perform an addition). Humans almost never write programs directly in machine code. Instead, they use programming languages. The simplest kind of programming language is assembly language which usually has a one-to-one correspondence with the resulting machine code instructions but allows the use of mnemonics (ASCII strings) for the "op codes" (the part of the instruction which encodes the basic type of operation to perform) and names for locations in the program (branch labels) and for variables and constants. Other languages are either translated by a compiler into machine code or executed by an interpreter
- machine shop — a workshop in which metal and other substances are cut, shaped, etc., by machine tools.
- machine tool — a power-operated machine, as a lathe, used for general cutting and shaping of metal and other substances.
- machine word — word (def 10).
- machine-word — a unit of language, consisting of one or more spoken sounds or their written representation, that functions as a principal carrier of meaning. Words are composed of one or more morphemes and are either the smallest units susceptible of independent use or consist of two or three such units combined under certain linking conditions, as with the loss of primary accent that distinguishes black·bird· from black· bird·. Words are usually separated by spaces in writing, and are distinguished phonologically, as by accent, in many languages.
- macintosh ii — (computer) (Mac II) A version of Apple's Macintosh personal computer, released in March 1987, using the Motorola 68020 CPU, which runs at a higher clock rate than the Motorola 68000 used in the original Mac. The Mac II has a full 32-bit data bus instead of a 16-bit bus. Mac II models have built-in 40 to 160 megabyte hard disks and can take up to eight megabytes of RAM (and more as denser memory chips arive). The Mac II was the first Macintosh to provide a colour graphics option, with up to 256 colours on screen at a 640x480 resolution. Mac II models are designed for expandability with three (Macintosh IIcx) or six (II & IIx) built-in NuBus expansion slots for additional peripheral and coprocessor boards.
