While it is possible to write computer applications as lengthy lists of numbers (device language) and whilst this technique was used with several early computers,[h] it is incredibly tedious and potentially error-prone to take action in follow, especially for sophisticated programs. Rather, Each individual essential instruction can be specified a brief name that is definitely indicative of its purpose and simple to keep in mind – a mnemonic for instance Incorporate, SUB, MULT or JUMP.
