==Description==
Assembly language is not a proper "programming language" per se, but rather a tool that allows you to write machine code using short, semi-human readable mnemonic instructions and link the into an executable, as an alternative to having to write streams of ones and zeroes and load them into memory. This effectively means that not only do each microprocessor family have their own assembly language format and instructions but also each processor version inside that family has its own instruction variations, but in addition to that different assemblers may use different mnemonic substitutes for each processor instruction.

Assembly language is not a proper "programming language" per se, but rather a tool that allows you to write machine code using short, semi-human readable mnemonic instructions and link the into an executable, as an alternative to having to write streams of ones and zeroes and load them into memory. This effectively means that not only do each microprocessor family have their own assembly language format and instructions but also each processor version inside that family has its own instruction variations, but in addition to that different assemblers may use different mnemonic substitutes for each processor instruction.
