Assembly Language

An assembly language is a low-level programming language for a computer, microcontroller, or other programmable device, in which each statement corresponds to a single machine code instruction. Each assembly language is specific to a particular computer architecture, in contrast to most high-level programming languages, which are generally portable across multiple systems.

Assembly language is converted into executable machine code by a utility program referred to as an assembler; the conversion process is referred to as assembly, or assembling the code.

Assembly language uses a mnemonic to represent each low-level machine operation or opcode. Some opcodes require one or more operands as part of the instruction, and most assemblers can take labels and symbols as operands to represent addresses and constants, instead of hard coding them into the program. Macro assemblers include a macroinstruction facility so that assembly language text can be pre-assigned to a name, and that name can be used to insert the text into other code. Many assemblers offer additional mechanisms to facilitate program development, to control the assembly process, and to aid debugging.

Famous quotes containing the words language and/or assembly:

    It is difficult for a woman to define her feelings in language which is chiefly made by men to express theirs.
    Thomas Hardy (1840–1928)

    There is a sacred horror about everything grand. It is easy to admire mediocrity and hills; but whatever is too lofty, a genius as well as a mountain, an assembly as well as a masterpiece, seen too near, is appalling.
    Victor Hugo (1802–1885)
