'''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.

For many CPUs, Machine code is generated from assembly language via an assembler, or sometimes directly from higher level languages such as C, via an interpreter or a [[compiler]].
