Assembly language

The Raspberry Pi comes equipped with an ARM v7 quad core processor. Each processor has its own set of specific machine code that it understands; this machine code is represented in binary format. The machine code is different for each processor architecture, so the Raspberry Pi's ARM processor machine code will not work on an IBM or Intel CPU.

Short of writing out 32-bit binary machine code instructions, the lowest level of programming language we can find ourselves using is Assembler language, also known as Assembly language.

The computer architecture's Assembly language is usually a one-to-one mapping between itself and the underlying machine code. This is achieved through using a mnemonic. A combination of these mnemonic codes will result in an operation such as addition or subtraction.

A program written in Assembly language is compiled into machine code by the Assembler program. This program passes through the code one or more times and generates an object file as part...
