Variables keep their symbolic name. IO interfaces keep their symbolic name. Operation codes receive a name that evokes the performed action. each machine instruction corresponds to one assembly language instruction An assembly language program can have pseudo instructions which do not correspond to machine instructions Machine vs. Assembly language
