Registers Note that each register has 32 bit, 16 bit and 8 bit names. We will usually use just the 32 bit names for the registers.

The full x86 instruction set is large and complex (Intel's x86 instruction set manuals comprise over pages), and we do not cover it all in this guide. For example, there is a bit subset of the x86 instruction set. Assembly language is also specific to the architecture (Here, we discuss Intel x86 and x64), whereas a language like C is portable. Assembly has a small (comparatively) set of commands: Commands that move data between various places; Commands that execute mathematic algorithms (simple to complex) Commands that check conditions (like if).
