Every processor or processor family has its own instruction set. Instructions are patterns of bits, digits or characters that correspond to machine commands. Thus, the instruction set is specific to a class of processors using (mostly)

A computer program is a list of instructions that can be executed by a central processing unit (CPU). A program's execution is done in order

The MIPS architecture provides a specific example for a machine code whose instructions are always 32 bits long. The general type of instruction

In some computers, the machine code of the architecture is implemented by an even more fundamental underlying layer called microcode, providing a common machine language interface across a line or family of different models of computer with widely different underlying

A much more human friendly rendition of machine language, called assembly language, uses mnemonic codes to refer to machine code instructions, rather than using the instructions'

On processor architectures with variable-length instruction sets (such as Intel's x86 processor family) it is, within the limits of the control-flow resynchronizing phenomenon known as th

Machine code is generally different from bytecode (also known as p-code), which is either executed by an interpreter or itself compiled into machine code for faster (direct) execution. An
