[[Category:Encyclopedia]]'''Assembly language''' (or just '''assembly'''; often abbreviated '''asm'''; sometimes called '''assembler''', although that more properly refers to the program that translates the assembly source into machine code) is a term used for a language which is as close to raw machine code as a language can get.

~~[[Category:Encyclopedia]]'''Assembly''' is a term used for a language which is as close to raw machine code as a language can get.~~ Usually ~~Assemblies~~ use textual ~~“mnemonic”~~ instructions that correspond directly to binary machine code instructions (merely hiding details of bit-wise encoding) except for ''macros'' which expand to multiple instructions, and often give direct control over the overall layout of the assembled program on disk and in memory. Available instructions and codes are specific to the architecture being programmed on. Assembly programs are loaded directly into a computer's memory and run from there.

Usually assembly languages use textual "[[wp:mnemonic|mnemonic]]" instructions that correspond directly to binary machine code instructions (merely hiding details of bit-wise encoding), except for ''macros'' which expand to multiple instructions, and often give direct control over the overall layout of the assembled program on disk and in memory. Available instructions and codes are specific to the architecture being programmed on (although there are assemblers which provide an abstracted, non-architecture-specific language; the most notable one is the [[wp:GNU Assembler|GNU Assembler]]). Assembly programs are typically loaded directly into a computer's memory and run from there.
