'''Machine code''' is a sequence of binary numbers that control a central processing unit ([[CPU]]). On very early computers, machine code was the language used to program computers. Since the 1960s, however, [[computer software]] is commonly written in a higher level language such as C, Java, [[FORTRAN]], and assembly language. | '''Machine code''' is a sequence of binary numbers that control a central processing unit ([[CPU]]).
